Daseul Ham, Sunghwan Park: 2 females (EMKU). Description: Medium sized Perlodinae, males brachypterous, females slightly brachypterous (Figs. 17–18). Forewing length: holotype male 7.5 mm, male paratypes 6.5–7.5 mm, female paratypes 10.0–11.0 mm; body length: holotype male 14.0 mm, male paratypes 12.0– 12.5 mm, female paratypes 15.0– 15.5 mm. Sexual dimorphism regards size, terminalia and different wing length: female wings terminate above tip of abdomen while male wings do not cover terminal segments; shortened male wing has less crossveins but branching Radial vein. Setation generally short and dense. General colour dark brown, contrasting pale pattern on wings and appendages. Head and pronotum entirely dark brown; tentorial callosities and M-line hardly visible, occiput with well developed but not contrasting rugosities (Fig. 11). Eyes and ocelli black and small, ocelli located far from each other, in a regular triangle.Antenna as long as the length of body, with more than 45 slightly clubbed antennomeres. Scape bicolored: base and inner edge dark brown, apex and outer edge light brown; pedicel and the next few antennomeres are light brown, gradually darkened towards dark brown two thirds of the antennae. Palpi brown, mouthparts mostly dark brown but glossa, paraglossa and apex of labrum contrastingly pale; vestigial submental gills present (Fig. 4). Pronotum rectangular, about as wide as long, edges rounded; rugosities numerous and small. Meso- and metanotum dark brown with whitish membranes around the wing base. Forewing with contrasting pattern: costal area and anal field shiny dark brown with metallic tint, the rest of the remigium off-white; venation brown, darker in the costal area. Hindwing is less contrasting, mostly brown with dark brown costal area (Figs. 2–3). Ventral surface of thorax contrasting: membranous areas white, while sclerotized plates brown to dark brown. Legs long and slender; tibiae distinctly longer than femora, and even more slender; claws symmetrical, arolium large. Femora dark brown with contrasting pale apical ring. Basal third of tibiae dark brown, then gradually lightened towards pale brown apical third. Tarsi light brown to brown but apical half of metatarsi dark brown. Ventral sclerites of thorax (Fig. 1): Prothorax: cervical sclerites large, with bud-like gill vestiges; rounded presternum fused with small basisternum,both with a longitudinal median ridge;precoxal bridge vestigial,eutrochantin well developed; furcasternum large and triangular, fused with basisternum, postcoxal bridge and medially ridged postfurcasternum; the furcasternal area similar to the mesothoracic furcasternum–furcasternal arm–furcasternal pit complex. Mesothorax: anterior thoracal bud-like gill vestiges present; spinasternum vestigial, presternum large and triangular, fused with the small, stripe-like basisternum; trochantin stripe-like; furcasternum large and triangular, fused with basisternum; furcal pit (furcasternal arm) connecting anteriorly to arm of mesosternal ridge that continued in a long stem (furcasternal pit); areas between furcal pit and stem sclerotized but hardly delimited. Metathorax: anterior thoracal bud-like gill vestiges present; spinasternum vestigial, presternum large and triangular, fused with the small, stripe-like basisternum; trochantin stripe-like; furcasternum large and quadrangular, fused with basisternum; furcal pit connecting to lateral margin of furcasternum; sternum I fused with furcasternum. Wing venation (Figs. 2–3, 5–6): Forewing: Costal field enlarged, with many irregular, often forked or interrupted crossveins between Costa and irregular Subcosta, humeral crossvein not clearly distinguishable. Subcosta joins the unbranched Radial vein before single radiomedial crossvein in the female, well after the branching of Radial vien in the male; there are one or two crossveins between Subcosta and Radial vein, further two between Costa and Radial vein, stigma is lacking. Medial vein originates independently from Radial vein but its base is obscure, the two veins are distinctly separated well before arculus; Medial vein branches into an irregular network shortly after arculus in the female, with several crossveins, and four longitudinal veins reaching wing margin. There are 3–5 mediocubital crossveins besides arculus. Cu1 and Cu2 branching before arculus, cubital cell quadrangular, there are 8–9 cubital crossveins in the female, 3–4 in the male; Cu1 ends about the position of Radial vein ending, last 2–3 crossveins end directly in wing margin, Cu2 ends about the position of Subcosta ending. Cubital vein and A1 basally fused, branches at the anal crossvein, cubitoanal crossvein distinct in the female but lacking in the male; A1 strongly curved after the crossveins, ends about half of wing length. There are three further anal veins besides A1; A2 and A3 can be connected with a crossvein, A4 is very short. Hindwing: Enlarged costal field, Costa, Subcosta and Radial vein network is generally similar to forewing, but humeral crossvein can be identified more distinctly. Origin of Medial vein separated from Radial vein, similarly to forewing, but irregular network of its branching is with less crossveins. There are two mediocubital crossveins besides arculus. Cu1 and Cu2 branching before arculus, cubital cell quadrangular but short, there are 5–6 cubital crossveins. Cubitoanal crossvein short and connected to a basal anal cell, there is an additional crossvein between Cu2 and A1 well after half wing length. Anal field very large and as long as the remigium, the fold of the wing extending between the parallel Cu2 and A1. Additional A veins are 7–8, branching irregularly, the last Anal vein gives irregular crossveins towards wing margin. Male abdomen (Figs. 7–8, 19–20): Segments I–II are fully divided into terga and sterna by pleura, segment III with shallow posterior notch of pleura, rest of the segments are entire. Terga I–III with wide, lightly sclerotized medial field, tergum IV with small medial field, terga V–IX entirely sclerotized and unmodified, dark brown; terga I–IX with entire antecosta, lack sensilla basiconica. Tergum X full divided into hemiterga; mostly dark brown, apical portions lighter, lack sensilla basiconica. Hemiterga triangular with rounded apex, the apical halves are converging in dorsal view, and elevated in lateral view; the wide basal anchor of epiproct divides hemiterga in the basal third by more than half of segment width, apices of hemiterga divided by a gap as wide as one fifth of the segment width. Sterna I–VIII brown, gradually darkening towards the apical segments, lacks vesicle. Sternum IX forms a well developed, rounded subgenital plate, covering sternum X and most of paraproct; sternum X widely divided medially. Paraproct dark brown, triangular with narrowed apical half, ending in a blunt apex; eversible portion is lacking. Cercus as long as the length of body, with 22–24 cylindrical segments, apical ones are rather elongated; basal 4–5 cercomeres yellowish, the rest is gradually darkened towards dark brown apical half of the cercus, but each cercomere with pale apical ring. Epiproct (Figs. 7–8, 12–14, 19–20): Basal anchor large and wide, connected to large, posteriorly directed lateral arms with raised tip, stretching basal membranes.The lever arm long and curved, rather wide in dorsal view, separated from the complex epiproct tip. The epiproct tip is shaped like an elongated 8 in dorsal, straight stripe-like in caudal, and half moon shaped in lateral view; most of the surface is lightly coloured but with a wide, lateral dark stripe and a dark dorsal ridge; the apex is arrow-shaped, tip slightly down curved in lateral view, and basally connected to rounded membranous portion. Paragenital plate large and bears ventral projection; stripe-like and slightly curved in dorsal view, dorsal portion darker in lateral view and with down curved apical portion, ventral projection has caudal edge perpendicular to the dorsal portion. Lateral stylet small, not fused and hidden in the cowl in resting condition of the epiproct; curved and stripe-like, apex with a curved, acute tooth. The cowl is densely covered by setae on most of its surface, with the exception of the dorsal surface basally to lateral stylets; bears a distinct, wide field of dense, tiny golden spikes between the stretched lateral stylets, seen only in fully everted position. In everted condition of the epiproct, the lateral arms of basal anchor raised dorsad, as well the rather enlarged cowl and epiproct tip that is fully exposed. Paragenital plates only slightly change posture, holding tight the base of the cowl. The lateral stylets are turning outwards by the base of the epiproct tip, stretching the apex of the cowl into two small, apicolateral lobes, and exposing the field of golden spines in front of the epiproct tip. The everted cowl has no other lobes, its shape is blunt conical in lateral, and rectangular in caudal view. Aedeagus (Figs. 15–16): Shape and lobes of the fully everted aedeagus remained unknown, but surface armatures and certain lobes around the armatures were clearly seen after dissection. On the ventral surface, golden brown scales are forming a large T-shaped loop; the scales are irregular small plaques with raised flanges. Adjacent to the upper part of the T, a pair of small lobules present, while the lower stem of the T is connected to a larger lobe forming an upside down C, bearing a small patch of scales beneath the stem of the T. Both the paired lobules and the lower lobe bear minute colourless spicules, scarce spinules distributed also on the surface beneath lower lobe; the surface lateral and above to the T is rarely wrinkled. The dorsal surface is armed with three small patches of golden scales similar to the ventral surface but no spicules; the upper two, elongated patches are positioned on inverting lobes, while the third, rounded patch is positioned medially on a rounded lower lobe. Female abdomen (Figs. 9–10): Segments I–II are fully divided into terga and sterna by pleura, segment III with shallow posterior notch of pleura, rest of the segments are entire. Terga unmodified, uniformly brown but apical two segments are darker, all with entire antecosta. Sterna I–VII brown, gradually darkening towards the apical segments. Subgenital plate reduced to a very slightly protruded, widely rounded posterior margin of sternum VIII, slightly bulging in lateral view; sternum VIII dark brown, with an inconspicuous longitudinal pale stripe medially. Sterna IX–X unmodified, dark brown but sternum IX with a mediobasal paler area. Paraproct dark brown with paler tip, elongated and narrow triangular, ending in a blunt apex. Cercus nearly as long as the length of body, with 24 cylindrical segments, apical ones are rather elongated; basal 3–4 cercomeres yellowish, the rest is gradually darkened towards dark brown apical two thirds of the cercus, but each cercomeres with narrow, pale apical ring. Egg: No fully matured eggs are available, but one of the females contains several dozens of nearly matured eggs. These are spherical, elongated oval with 0.3–0.4 mm length and 0.2–0.3 mm diameter. The chorion is golden light brown, apparently with dense punctuations of FCIs. No traces of collar or rims can be recognized. Larva: unknown. Affinities: As for the genus. Ecology and distribution: The species was caught by Malaise traps during May, June and July. The traps were set at elevations ranging from 700 to 1300 m, along medium sized forest streams with fast flow and mixed rocky and sandy substrate (Fig. 21). The known localities are located in the Thebaek ranges, in three counties of Gangwon province (Gangwon-do): Inje-gun, Pyeongchang-gun, Jeongseon-gun (Fig. 22). Etymology: The name koreanus refers to the Korean Peninsula where this remarkable stonefly was found.

Materials examined: The specimens re-studied from Guangxi, Guizhou, and Jiangxi were recorded in Zhao (2019) and Zhao et al. (2019). Distribution: Fujian, Guangdong, Guangxi, Guizhou, Jiangxi and Zhejiang. Remarks: The shorter process lateral to the basal cercal segment has forks of different sizes and shapes and on some males are asymmetric (Fig. 5A–C). The small lateral spines present along the longer medial process on basal cercal segment varies in distance from the apex, sometimes as much as two-fold (Figs. 6A–B). In one particular male, the left and right process on basal cercal segment are completely asymmetric, with one side having a shape similar to that of specimens (Zhao et al. 2019, Mo et al. 2022) previously determined as S. jiangxiensis (Figs. 6C – D)., Published as part of Huo, Qing-Bo, Zhao, Meng-Yuan, Du, Yu-Zhou, Murányi, Dávid, Zhu, Bin-Qing & Yu, Lei, 2023, The intraspecific morphological variability of Styloperla Wu, 1935 (Plecoptera: Styloperlidae), pp. 125-137 in Zootaxa 5249 (1) on page 128, DOI: 10.11646/zootaxa.5249.1.7, http://zenodo.org/record/7685409, {"references":["Wu, C.

Habaek gen. n. Diagnosis: Medium sized, dark brown Perlodinae with contrasting pale pattern on wings and rather long appendages; vestigial submental and thoracal gills present, furcal pit anteriorly connected to mesosternal ridge. Wings with enlarged costal field in both sexes, and unbranched Radial vein in the female. Male: sterna lack vesicle, terga lack sensilla basiconica, tergum X widely divided into triangular hemiterga; epiproct with large basal anchor and lateral arm, large paragenital plate and ventral projection, small lateral stylet and densely setose cowl, large and complex epiproct tip that is not connected with wide lever arm. Aedeagus displays a distinct pattern of golden scales. Female: subgenital plate reduced. Type species: Habaek koreanus sp. n., by monotypy. Affinities: The present tribal concept of the subfamily Perlodinae recognizes three tribes, based mainly on larval and egg characters and a few distinct characters of the male terminalia (Stark & Szczytko 1984, 1988). The lack of finger-like male hemiterga preclude the new genus from the tribe Arcynopterygini, while the lack of male sternal vesicle preclude it from Diploperlini. Consequently, we classify it in the Perlodini. However, discovery of the larva and matured egg may require modification of this classification. The spherical shape of immature eggs found in the paratype females already suppose classification in Arcynopterygini, since, with few exceptions, Perlodini species have eggs triangular in cross section, but it cannot be excluded that eggs become triangular when fully matured. The anteriorly connected furcal pit and mesosternal ridge is unique among Perlodini, while usual in Arcynopterigini (Arcynopteryx, Frisonia Ricker, 1943, Megarcys, Neofilchneria Zwick, 1973, Pseudomegarcys Kohno, 1946, Skwala Ricker, 1952) and rare in Diploperlini (Osobenus Ricker, 1952 and Stavsolus). Probably more important, and supportive of the new genus being classified in Perlodini, is the presence of fully divided but widely rounded hemiterga that lacks sensilla basiconica. This type of hemiterga occur only in the Perlodini: Tadamus Ricker, 1952 and an unnamed genus sensu Inada (1996) and Shimizu et al. (2005) from Japan, Malirekus Ricker, 1952, Oconoperla Stark & Stewart, 1982 and Yugus Ricker, 1952 from the eastern Nearctic, and Susulus Bottorf, Stewart & Knight, 1989 from California. The arrow-like apex of the epiproct tip is another character shared in only a few Perlodini genera (Dictyogenus Klapálek, 1904, Hydroperla Frison, 1935 and Isogenoides Klapálek, 1912) and not known in the Arcynopterygini and Diploperlini. The extreme reduction of the female subgenital plate is unique among the Perlodinae, though poorly produced subgenital plate is characteristic for the Pacific East Asian Megaperlodes and the Californian Salmoperla Baumann & Lauck, 1987. The presence of thoracic gills is characteristic for the Arcynopterygini. The new genus is the only Perlodini where thoracic gills are documented; however, gill vestiges are small and can be easily overlooked. Submental gills may both be present or lacking in all three tribes. In the Perlodini, more or less developed submental gills are present in Helopicus Ricker, 1952, Hydroperla, Isogenoides, Malirekus, Susulus, Tadamus, Yugus and the new genus. There are four genera of Perlodidae that are characterized by an entirely dark head and pronotum: Hemimelaena Klapálek, 1907, Levanidovia, Tadamus Ricker, 1952 and the new genus. Surprisingly, three of these are restricted to the southern temperate Pacific area of Asia and classified in the Perlodini, though they are apparently not closely related. Contrasting dark and pale wing pattern is rare among the Asian Perlodidae; besides the new genus, patterned wings are known for Megaperlodes tiunovi Teslenko, 2015 and Filchneria zhouchangfai (Chen, 2020), both of which belong to the Perlodes genus group sensu Zwick (1997). The enlarged costal field and unbranched Radial vein of both fore- and hindwings are unique among Perlodidae, and can be regarded as apomorphies. The enlarged costal area (and unusually large, rounded anal field of hindwing) is reminiscent of the Antarctoperlarian family Eustheniidae, but it surely does not reflect on phylogenetic relations with that basal family. The unbranched Radial vein of the female is unique among the Plecoptera. Etymology: The new genus is named after the Korean water god Habaek.

Kamimuria simplex (Chu, 1929) http://lsid.speciesfile.org/urn:lsid: Plecoptera.speciesfile.org:TaxonName:7456 (Figs. 1–4) Perla simplex: Chu, 1929: 88; Claassen, 1940: 145. Kamimuria simplex: Wu, 1938: 200; Du, Sivec & He, 1999: 61; Sivec & Stark, 2008: 137; Stark & Sivec, 2013: 117, nomen dubium; Yang & Li, 2018: 31. Supplementary description: Male coloration mostly dark brown to black (Fig. 1A); area between eyes to ocellar triangle dark and ventrally most parts of head and thorax yellowish (Fig. 1A–B). Male metasternum and sterna 3–7 with setal brushes (Fig. 1A). Terga 1–7 unmodified. Sensilla basiconica patches occur both as a round dark spot present on posterior tergum 8 and a median longitudinal dark area of tergum 9 that is much denser (Fig. 2A). Hemitergal lobes are slender, hooklike, extending backward to the posterior margin of tergum 9 (Fig. 2A). Aedeagus membranous; basal half with paired patches of large spines mediolaterally on the swellings; distal half with two paired swellings (Fig. 2B–C), the apical pair are larger than the basal pair; apex with dense fine spines ventrally, and a pair of ventrolateral patches of thicker and long spines arranged in “C” shaped semicircles (Fig. 2D). Female coloration similar to male (Fig. 3A–B). Abdomen brown; sterna 6–8 slightly sclerotized medially. Subgenital plate with a pair of posterolateral lobes of which apex rounded and adjacent to each other; the notch between the lobes “Ω” shaped, darker than other parts of the plate (Fig. 4).

Nemoura alticalcaneum Mo, Wang & Li, sp. nov. (Figs. 2–4) Adult habitus. Head and mouthparts black; antennae brown but scapus and pedicel darker, palpi brown; compound eyes black. Pronotum dark brown, rectangular, corners rounded, with obscure rugosities. Legs pale brown but the apical half of tibia of hindlegs brown to dark brown; wings brownish with dark marks around the X pattern and in the basal costal field, veins dark. Abdominal segments brown but terminalia darker with pale hairs. Male (Figs. 2–4). Forewing length 5.5–5.7 mm (n=2). Tergum 9 (Figs. 2c, 3b) slightly sclerotized except anterior margin heavily sclerotized, constricted medially with a deep and broad, semicircular posterior indentation, and a few long hairs along posterior margin. Sternum 9 (Figs. 2b, 3a) with stubby claviform vesicle, length ca. 2X maximum width, slightly constricted basally; hypoproct at first half broad and rectangular, gradually tapering towards the sharp apex, with an abruptly constricted subapically. Tergum 10 (Figs. 2c, 3b) mostly sclerotized, with a narrow membranous longitudinal concavity beneath epiproct; lacks spines. Cercus (Figs. 2b–2c, 3a, 3b, 3d, 4b) basally distinctly sclerotized, medially with a ventrolateral short process (Figs. 2b–2c, 3a–3b): the process has a distinct basal bald stalk and a black spine; apical half mostly membranous, and gradually tapering towards sharp tip forming a black spike curved dorsad. Epiproct (Figs. 2c–2d, 3b, 4): rectangular, nearly 2X longer than width, with a short and rounded cone-shaped projection. Medium sized basal cushion located above the small basal sclerite. Pair of small dark ventral arms delimitate dorsal sclerite ventrally, subtriangular in lateral view. Lateral arms distinctly sclerotized, subrectangular, originate from basal dorsal fold and run along lateral sides of the epiproct. Ventral sclerite basally with a pair of small lateral knobs, after the broad base it is continued in a stout and short basal plate that bears two rows of three to four stout spines; ring of the ventral sclerite originates before the apical part of basal plate, moderately long and subrectangular, covered by a large membranous lobe; prongs widely connected to the ring, conical and lacks distinct teeth; the cone-shaped projection is short and wide, linear sclerotized area indistinct. Paraproct (Figs. 2b–2c, 3) divided into two lobes: outer lobe distinctly sclerotized and subdivided, inner lobe slightly sclerotized, long, slender and triangular with a rounded tip. Basal half of outer lobe is broad, with a triangular inner portion subdivided from outer portion and the apical half; apical half strongly sclerotized, curved outwards basally and then strongly upwards, apex is tapering toward the sharp tip forming a high-heeled process, curved inwards. Female. Unknown. Type material. Holotype: male (CAU), China: Guangxi, Guilin City, Xing’an County, Tongren Village, Maoershan National Natural Reserve, 25°54'18" N, 110°26'24" E, 1873 m, 2004.V.4, Yang D. Paratype: 1 male (HIST), the same data as the holotype. Etymology. The name refers to the high-heeled process of the apical half of the outer paraproct lobe. Latin “ altus ” means high, and “ calcaneum ” means heel. (Shimizu 1997; Sivec & Stark 2010a). It can be distinguished from the latter by the following characters: the cercal segment has a slender apical spike and lacks dorsal seta; the apical portion of hypoproct is slim with a sharp tip; the paraproct has complex outer lobe, apically with a high-heeled process. In N. magniseta, the cercal segment has a rounded simple tip and dorsally bears a distinct seta; the apical portion of the hypoproct is nipple-like with a rounded tip; the paraproct is simple, its outer lobe having a small mesoapical projection. In general, the exceptionally modified, subdivided outer lobe of the paraproct is unique among the Nemoura species., Published as part of MO, RAORAO, WANG, GUOQUAN, YANG, DING, LI, WEIHAI & MURÁNYI, DÁVID, 2022, Review and contribution to the stoneflies (Insecta: Plecoptera) of Guangxi Zhuang Autonomous Region, China, with new species and new records from South China, pp. 1-80 in Zootaxa 5176 (1) on pages 6-7, DOI: 10.11646/zootaxa.5176.1.1, http://zenodo.org/record/7025356, {"references":["Shimizu, T.

Nemoura ganeum Mo, Yang & Li, sp. nov. (Figs. 6 –9) Adult habitus. Head and mouthparts black; antennae dark brown, palpi brown; compound eyes black. Pronotum dark brown, rectangular, corners rounded with obscure, black cuticular rugosities. Legs pale brown; wings brownish, subhyaline with dark veins. Abdominal segments brown but terminalia darker with pale hairs. Male (Figs. 6–8). Forewing length 5.4–5.7 mm (n=2). Tergum 9 (Figs. 6c, 7b) slightly sclerotized except antecosta heavily sclerotized, constricted medially with a deep, broad semicircular anterior indentation; a triangular posterior indentation present with a few long hairs along posterior margin. Sternum 9 (Figs. 6b, 6d, 7a, 7c) with claviform vesicle, length ca. 3X maximum width, slightly constricted basally; hypoproct basally broad and oval, gradually tapering medially to a rounded tip. Tergum 10 (Figs. 6c, 7b) mostly sclerotized, medially with a narrow membranous longitudinal elliptical concavity in front of epiproct, lacks spines. Cercus (Figs. 6b–6d, 7, 8a) basally distinctly sclerotized but apical half mostly membranous, sclerotized portion gradually tapered to a sharp tip forming a strongly upcurved black spine; cercus length twice width. Epiproct (Figs. 6c–6d, 7b–7d, 8): subquadrate, nearly as long as wide, with a moderately long and rounded cone-shaped apical projection. Medium sized basal cushion located above the basal sclerite. Pair of small dark ventral arms delimit dorsal sclerite ventrally, subtriangular in lateral view. Lateral arms distinctly sclerotized, subrectangular, originate from basal dorsal fold that do not run along lateral sides of the epiproct. Ventral sclerite basally with pair of small lateral knobs, after the broad base continued in a stout basal plate that bears two rows of six spines; ring of the ventral sclerite originates before the apical part of basal plate, moderately long and rounded; prongs widely connected to the ring, tongue-shaped and armed with two teeth; the cone-shaped projection is moderately long and wide, linear sclerotized area distinct. Paraproct (Figs. 6b, 6d, 7) divided into two lobes: outer lobe sclerotized, basal half broad and subtrapezoidal, apical half membranous; inner lobe sclerotized, slender and claviform with a rounded tip. Female (Fig. 9). Sternum 7 extended medially, forming a well-developed, broadly hexagonal pregenital plate, which is strongly sclerotized, overlapping sternum 8 completely; ring-shaped inner sclerite transparent through its surface after NaOH treatment.

Holotype: male (HIST), China: Guangxi, Nanning City, Wuming County, Damingshan National Nature Reserve, vicinity of a restaurant, 23°29'45" N, 108°26'14" E, 1225 m, 2015.III.22, Kontschán J, Li JY, Li S, Li WH, Murányi D, Wang GQ; Paratypes: 1 male (HNHM), 1 female (HIST), same location and collectors as holotype Etymology. The name refers to the restaurant where it was collected. The Latin “ ganeum ” means restaurant. Distribution. China (Guangxi Zhuang Autonomous Region). Remarks. The new species belongs to the ovocercia group, and it is most similar to certain northeast Indian species, namely Nemoura chugi Aubert, 1967 and N. mawlangi Aubert, 1967 (Aubert 1967; Shimizu 1997). These species have similar paraprocts, and similar cercus and epiproct. Both can be distinguished from the new species on the basis of having their cercal spine originating about the middle length of cercus, and the prongs of the epiproct are sharp, instead of tongue-shaped. These two Indian species were indicated as members of the cercispinosa complex by Baumann (1975), however, they meet with the definition of the ovocercia group sensu Shimizu (1997)., Published as part of MO, RAORAO, WANG, GUOQUAN, YANG, DING, LI, WEIHAI & MURÁNYI, DÁVID, 2022, Review and contribution to the stoneflies (Insecta: Plecoptera) of Guangxi Zhuang Autonomous Region, China, with new species and new records from South China, pp. 1-80 in Zootaxa 5176 (1) on pages 11-14, DOI: 10.11646/zootaxa.5176.1.1, http://zenodo.org/record/7025356, {"references":["Aubert, J.

Nemoura tauripitis Mo, Li & Murányi, sp. nov. (Figs. 11 –13) Adult habitus. Head and mouthparts pale brown; antennae pale brown, palpi pale; compound eyes black. Pronotum pale brown, rectangular, corners rounded with obscure darker cuticular rugosities. Legs brown; wings brownish subhyaline with brown veins. Abdominal segments brown but terminalia darker with pale hairs. Male (Figs. 11 –13). Forewing length 5.4–5.8 mm (n=3). Tergum 8 (Figs. 11c, 12b) weakly sclerotized, with four large, stout spines. Tergum 9 (Figs. 11c–11d, 12b) sclerotized, constricted medially with a deep and broad, semicircular indentation anteriorly, and produced posteromedially into a pair of distinct triangular processes. The processes are armed asymmetrically with 1–2 large apical spines, and several scattered large median spines. Sternum 9 (Figs. 11b, 12a) with slender claviform vesicle, length ca. 4X maximum width, slightly constricted basally; hypoproct basally broad and oval, abruptly tapering toward rounded tip. Tergum 10 (Figs. 11c–11d, 12b, 13e) mostly sclerotized but medially with a narrow, weakly sclerotized longitudinal concavity; large and stout spines occur medially on the tergum along the concavity, and a pair of large humps present on either sides of the concavity, ending in a large spine at tip. Cercus (Figs. 11b–11c, 12a–12b, 12d, 13a–13b, 13d) distinctly sclerotized, except inner margin membranous; a large ventrobasal hooked process originating from the inner basal portion, curved dorsad; apex of cercus rounded, curved inwards. Epiproct (Figs. 11c–11d, 12b, 13): bull head shaped, nearly 1.5X longer than the widest width. Large basal cushion located above the small basal sclerite. Pair of large dark ventral sclerite basally with pair of small lateral knobs, after the moderately broad base continued in a stout basal plate that bears rows of five to six spines; ring of the ventral sclerite very small and thin, originates before the apical part of basal plate, covered by a membranous lobe; prongs widely connected to the ring, horn-shaped and curved outwards, lacks teeth; the cone-shaped projection is short and slim, linear sclerotized area indistinct. Paraproct (Figs. 11b, 12a, 12c–12d) divided into two lobes: outer lobe sclerotized, large apically rounded, with a weakly sclerotized oval area at the inner base; inner lobe sclerotized, short and slender, banded with a truncated tip.

Paratypes: 1 male (CAU), 1 male (HIST), same data as holotype, Etymology. The name refers to the bull head shaped epiproct. Latin “ taurus ” means bull, and “ -pitis ” means head. Distribution. China (Guangxi Zhuang Autonomous Region). Remarks. The new species has a similar male sternum 9, male tergum 10, paraproct and cercus to that of two Chinese species: Nemoura cochleocercia Wu, 1962 and N. mucronata Li & Yang, 2008. However, the new species is easily distinguished from N. cochleocercia and N. mucronata by the distinctive prongs of the epiproct. In addition, the cercus of N. cochleocercia is much wider than that of the new species, while the hooked process of the cercus originates around midlength in N. mucronata, contrary to the basal position of the process of the new species. The new species is most similar to the Indian species, N. chugi. They share similar male sternum 9, paraproct and cercus and the horn-sharped prongs of epiproct, but the new species can be separated from the latter by tergum 10 having a pair of triangular processes, epiproct having a well sclerotized pair of lateral arms and the subtrapezoidal basal cushion. In N. chugi, according to the original description, tergum 10 is simple and lacks additional processes or humps, and the epiproct lacks sclerotized lateral arms and the basal cushion is rectangular. In addition, the apical portion of epiproct in the new species is covered by a membranous lobe, while the original figures of N. chugi do not show any membranous lobe., Published as part of MO, RAORAO, WANG, GUOQUAN, YANG, DING, LI, WEIHAI & MURÁNYI, DÁVID, 2022, Review and contribution to the stoneflies (Insecta: Plecoptera) of Guangxi Zhuang Autonomous Region, China, with new species and new records from South China, pp. 1-80 in Zootaxa 5176 (1) on pages 16-19, DOI: 10.11646/zootaxa.5176.1.1, http://zenodo.org/record/7025356, {"references":["Wu, C.

The species is included in the revision of Taiwanese Neoperla by Sivec & Zwick (1987), but as a mainland species and no Taiwanese specimens were enumerated among the material examined. Remarks. Both sexes of most examined Guangxi specimens agree well with illustrations and redescription of the designated lectotype: (compare Figs. 23–24 with figs. 9–13 in Sivec & Zwick 1987). However, the male from Huaping (Fig. 24) differs slightly in the spinulation of the aedeagal sac. This variation was already reported for Yunnan specimens of N. cavaleriei, and the species was considered a probable complex with N. lui Du, 2004 (in: Du & Sivec 2004) (Li et al. 2014c). We note that N. kachin was not considered as a junior synonym of N. cavaleriei by Sivec & Zwick (1987). Only the female sex of N. kachin, figured in the original description (Stark & Szczytko 1979), was considered conspecific with N. cavaleriei. Nevertheless, the specific identity of N. kachin is in need of clarification, since the details of aedeagal sac spinulation was not described., Published as part of MO, RAORAO, WANG, GUOQUAN, YANG, DING, LI, WEIHAI & MURÁNYI, DÁVID, 2022, Review and contribution to the stoneflies (Insecta: Plecoptera) of Guangxi Zhuang Autonomous Region, China, with new species and new records from South China, pp. 1-80 in Zootaxa 5176 (1) on page 29, DOI: 10.11646/zootaxa.5176.1.1, http://zenodo.org/record/7025356, {"references":["Navas, R.

Neoperla fanjingshana Yang & Yang, 1992 (Figs. 25–26) Neoperla fanjingshana Yang & Yang, 1992: 63; Du, Sivec & He, 1999: 62; Yang & Li, 2018: 39; Mo, Liu, Li & Shi, 2020: 375. Supplementary description. Tergum 6 bears a few posterior sensilla basiconica, further terga agree with the original description (Fig. 25c, 26a). Aedeagus (Figs. 26b–26e) mostly membranous. Aedeagal tube (Figs. 26b–26c) nearly straight, only dorsal surface sclerotized. Aedeagal sac (Figs. 26b–26e) slightly longer than tube and strongly curved ventrally, and in our only specimen it forms a loop looking like a lowercase “b”; dorsal surface of basal half irregularly covered with scattered brown spines, but its ventral surface bare; near sac apex lateral spines become large, dark with a broad base and hooked apex, occurring in two groups, one of 3–4, the more distal of 2; apex of sac with a H-shaped, dark uneverted sclerite (Fig. 26e), dorsal surface covered in a field of smaller spinules. Material examined. 1 male (HIST), China: Guangxi, Laibin City, Jinxiu Yao Autonomous County, Dayaoshan National Natural Reserve, Yinshan Park, 24°10'07" N, 110°14'38" E, 1129 m, 2020.VI.11, light trap, Mo RR, Lai Y et al. Distribution. China (Guangxi and Guizhou). Remarks. This species was originally described from Fanjing Mountain of Guizhou Province by Yang and Yang (1992). However, the aedeagal sac of the holotype was not everted and described. Other aspects from the original description agree well with the Guangxi specimen (compare Figs. 25–26 with fig. 2 in Yang & Yang 1992). The only difference is that our male specimen has a few sensilla basiconica on tergum 6 posteromedially, which are easy to overlook. This species is a member of the Neoperla montivaga group, sinensis species subgroup as defined by Li & Yan (2021), having a pair of apical sclerites of aedeagal sac. The recently described Neoperla annulatispina Mo, Li & Wang, 2021 from Guangdong Province also fit the definition of this subgroup and can be included.

Egg oval, with marked ornamentation of FCIs, collar with slightly flanged rim. Larva with pronotum half as long as wide, lacinia trapezoid shaped, paraproct blunt with widely rounded apex, cercus lacks dorsal hair fringe. Description of the larva: Body length of the mature larva: 16.0���18.0 mm (n=3). General colour brown, with indistinct paler markings on the dorsum and pale ventral aspect (Figs. 1, 3���4). Pilosity usual for the genus, consists of fine black clothing hairs and acute marginal spines. Occipital row dense, medially interrupted only at the occipital suture (Figs. 1, 9���10); pronotal marginal fringe distinct, longest spines are as long as one tenth of pronotal width (Figs. 1, 12); posterior tergal fringe with acute spines nearly half as long as tergal length on tergum 5 (Figs. 3, 13); cercal apical fringes dense but short and acute, on medial cercomeres most are shorter than one sixth of the length of segments but one or two spines of the fringe reach about one third of the length (Fig. 14); dorsal hair fringe lacking from the entire cercus (Figs. 7, 14). Head mostly brown and lacks interocellar spot, yellow markings limited to a small spot on the occipital suture, tentorial callosities and M-line; occipital rugosities and lateral occipital spots obscure; eyes small, the head is rather wide and frontal area slightly elongated (Fig. 1). Scape and apical half of pedicel brown, following antennomeres paler; palpi and mouthparts light brown, with dark edges on the maxilla and mandible (Fig. 11). Lacinia bidentate, wide trapezoid shaped; subapical tooth more than half of the length of apical tooth; submarginal row with one A seta interrupted from three B setae, the last one is being much shorter than previous two; one thin marginal seta (TMS) and one dorsal seta (DS) present; 9���11 marginal setae (C) initially widely spaced, last few shorter and closer, difficult to differentiate from dorsal surface setae; 12���16 ventral surface setae (D) starting from submarginal setae B, ending posteriorly at approximately four fifth of the inner lacinia margin length; dorsal surface setae (DSS) continue from last marginal seta (C) as a single submarginal row along inner-lateral margin, ending before posteriormost ventral surface setae (Figs. 15, 17, 19). Galea with 6���10 surface setae and 3���4 apical setae, basally slightly swollen, reaching base of apical tooth (Figs. 15, 17, 19). Mandible with three molars and three incisor dens, molar brush dense and long (Figs. 16, 18, 20). Pronotum short and slightly narrower than head, length half of width; brown with indistinct paler rugosities (Fig. 1). Mesonotum and metanotum mostly brown with indistinct pale brown pattern, wingpads paler; outer margin of wingpads nearly straight (Fig. 1). Thoracic sternites entirely pale, furcasternites and furcal pits large and slightly darker (Fig. 4). Legs entirely brown, tarsal claw lengths equal (Figs. 1, 3). Abdomen divided laterally by pleura in the first two segments; abdominal terga brown with moderately distinct, paired oval pale patch medially (Figs. 3, 13). Ventral surface of abdomen pale, the distal segments slightly darker. Paraprocts brown, large and blunt, apex widely rounded (Figs. 5, 7). Cercus light brown to brown, cercomeres cylindrical; medial cercomeres twice as long as wide (Fig. 14). Updated characters of the male: Paraprocts dark brown, blunt, wide and slightly recurved in dorsal view (Fig. 63 in Mur��nyi (2011)). In caudal view, the base is wide and bears only a very small membranous portion; apex bluntly triangular, inner edge slightly sinuous (Fig. 22). Penis (Fig. 21): Divided into four lobes and a tubular basal section when extruded, lateral lobes poorly developed. The medial penial armature is divided into an upper and a lower part, lateral penial armatures lacking. Lower part of the medial armature located on the ventral lobe, upper part is on the medial lobe between the vestigial lateral lobes. The upper part of medial armature trapezoidal, tapered towards basal section; length 350 ��m, width 200 ��m. The lower part of medial armature is rounded triangular or rounded, length 200 ��m, width 220 ��m. The scales are spike-like, all of the same width, but those on the lower part are less dense, and generally shorter; width 15 ��m, length 30���100 ��m. The ventral lobe is small and weakly separated from the basal section, mostly aspinulate besides bearing the lower part of medial armature; spike-like coloured scales of the armature gradually turn into colourless triangular scales basolaterally, triangular scales continued on the basal section. The medial lobe is large and spherical, bearing the upper part of medial armature; upper edge of the armature transitioning into colourless triangular scales, then rapidly transitioning into hydra-like scales that are covering a wide area on the ventrobasal surface, becoming denser towards margins of the scale field; apical area aspinulate, lateral margin connecting small lateral lobes with small hydra-like scales. Lateral lobe is poorly developed and hardly delimited from medial lobe; mostly smooth, but with lateral band of small hydra-like scales, and a few sensillae. The basal section is completely covered by triangular scales. Egg: Chorion brown; length 0.28���0.35 mm, width 0.22���0.26 mm (n=8). Shape oval, opercular end usually depressed, collar end less rounded; cross section rounded or indented. Hatching line inconspicuous. Micropyles in a row on the opercular third, not raised, each located on the junction of carinae between follicular cell impressions (FCIs). Chorion with marked ornamentation of penta- and hexagonal FCIs. Collar round, rim slightly flanged, bears one row of FCIs. Anchor large and flat. Distribution and biology: Isoperla vevcianensis has a narrow endemic distribution, restricted to the Jablanica Mts, on the border zone of Albania and North Macedonia (Ikonomov 1980, Mur��nyi 2011). The species is mostly associated with headwater brooks in the alpine and subalpine grasslands, at elevations above 1100 meters (Figs. 25���27). The adults emerge in June and July. The adult and larval specimens from our study were found together with Leuctra metsovonica Aubert, 1956, Perla cf. pallida and another Isoperla species belonging to the I. tripartita species complex (sensu Mur��nyi et al. 2016). Species relationships: Isoperla vevcianensis was assigned to the Isoperla silesica group sensu Mur��nyi (2011) on the basis of the male penial armatures. Monophyly of the two Central European-Alpine species, I. silesica Illies, 1952 and I. zwicki Tierno de Figueroa & Fochetti, 2001 with the Central Balkanian I. vevcianensis and I. breviptera Ikonomov, 1980 should be confirmed by details of the penial lobes and cox-1 sequences, but these are known only for I. vevcianensis. The mature larva is distinctive among congeners by its large head and short pronotum, similar to the Alpine I. claudiae Graf & Konar, 2014 (in: Graf et al. 2014) and the Crimean I. prokopovi Zhiltzova & Zwick, 2012. An undescribed species from Montenegro, closely related to I. breviptera, has similar large head and short pronotum (W. Graf, pers. comm.). In the collection of the MM, we have larvae similar to the Montenegrian species, and probably belong to the same undescribed species from Kosovo. The wide trapezoid shaped lacinia is also unique among European species, but this character is rather variable among Nearctic species (Hilsenhoff & Billmyer 1973, Stewart & Stark 2002, Sandberg 2011). The blunt paraproct is unique among the known larvae of the genus (Zwick 2004), though this character is not documented for the East Palaearctic and Nearctic species (Stewart & Stark 2002, Teslenko & Zhiltzova 2006, and Sandberg 2011). For comparison, head, pronotum and paraprocts of sympatric larvae of the unidentified member of the I. tripartita species complex are depicted on Figs. 2, 6, and 8. Larvae of the I. tripartita species complex display characters typical for the West Palaearctic Isoperla. The egg of I. vevcianensis proved to be the usual type of West Palaearctic species, similar to those of e.g. I. tripartita tripartita as depicted in Mur��nyi (2011). Genetics. Haplotypes from Isoperla vevcianensis formed a cluster of identical sequences for the coxI gene (Fig. 24) with zero intraspecific genetic distance. Molecular analyses agreed with the morphological association between female, male and larvae of I. vevcianensis based on sequence similarities among the specimens. Interspecific genetic distances between I. vevcianensis and the members of the I. tripartita species complex exhibited a 3% divergence, suggesting different species., Published as part of Mur��nyi, D��vid, Kov��cs, Tibor, Gamboa, Maribet & Watanabe, Kozo, 2021, Loss of a larval generic character: an interesting and new description for Isoperla vevcianensis Ikonomov, 1980 (Plecoptera: Perlodidae) with updated adult characters, pp. 541-552 in Zootaxa 5082 (6) on pages 543-548, DOI: 10.11646/zootaxa.5082.6.2, http://zenodo.org/record/5797606, {"references":["Ikonomov, P.

Legs pale brown, joints darker; wings subhyaline and yellowish brown, veins brown, Sc of forewing short, typical of the genus; cerci pale. ABDOMEN (Figs 1B–D, 3D–E). Sterna 3–5 with hair brushes. Dark median sclerite of tergum 9 trumpetshaped, about half as long as the segment, heavily sclerotized, distally forked with two blunt points. Hemitergal processes slender, about 2.5× as long as basal width; triangular in lateral view; basal callus fully covered with sensilla basiconica. AEDEAGUS (Figs 2, 3F). Aedeagal tube dorsally sclerotized, sclerite forming a T-shaped marking. Sac as long as the tube when fully everted, distinctly curved dorsad; dorsoapical surface with a low membranous median lobe and several small spines located in a fringe; a single large straight spine about as long as ⅓ aedeagus length and a large spinose lobe medially at apex, directed dorsally; ventral surface with a large basal patch of spinules, and a rectangular sclerite armed with three to five spines arranged in a combshape; two subapical groups of small spines located in ventrolateral surface; lateroapical part with six large curved spines on each side. Female ADULT HABITUS (Fig. 4A). Forewing length ca 8.0 mm, hindwing length ca 7.0 mm. Habitus generally similar to male. ABDOMEN (Fig. 4B). Subgenital plate of sternum 8 slightly produced, triangular, bearing a small semicircular mesal notch. EGG (Figs 4C–D, 5). Length 272–280 μm, width 214–218 μm (N = 5). Several mature eggs were dissected from female terminalia. Oval-shaped with obscure opercular line, widest in subequatorial area towards opercular end. Anchor absent from the studied eggs. Collar short and button-shaped. Chorionic surface brown with heavy and distinct punctuations throughout. Micropylar orifices sessile, much larger than punctuations, set on subequatorial line. Distribution China: Hainan Province. Known only from the type locality. Remarks One of the male paratypes of C. nigrifrons (Banks, 1939) belongs to C. changjiangensis sp. nov. The aedeagal tube of this male had been damaged before our examination.After further gentle squeezing, the sac was nearly fully everted but quite distorted; the observable armatures are illustrated on Fig. 3F. Since the aedeagus is partly damaged, we are not sure whether additional spines remained hidden and were not disclosed in the present study, hence the specimen is not designed as a paratype of C. changjiangensis sp. nov. The new species and C. biprojecta Lü, Yan, Li & Wang, 2019 are most similar in head pattern, hemitergal processes, aedeagal tube, and aedeagal sac that is apically armed with a long spine, a large lobe and a comb-shaped sclerite. However, C. changjiangensis sp. nov. is easily distinguishable from the latter by the trumpet-shaped median sclerite of tergum 9 and the comb-shaped sclerite of the aedeagal sac with five short spines arising from the rectangular sclerite. In C. biprojecta, the median sclerite of tergum 9 is triangular with two finger-shaped projections bearing several black tiny warts, and the comb-shaped sclerite has four longer spines extending from the triangular basal sclerite. The apical portion of the aedeagal sac of the new species has six curved lateral spines on each side and three groups of short spines, while in C. biprojecta the lateroapical spines of the aedeagus are longer and hook-like, without more spine groupings. In addition, the apical lobe of the aedeagus of C. changjiangensis sp. nov. is covered with distinct small spines, whereas in C. biprojecta it is bare. Besides the distinctly different armatures of the aedeagal sac, C. changjiangensis sp. nov. can easily be distinguished from the sympatric C. nigrifrons by external morphology: the anterolateral extension of the interocellar marking is moderately angled, not so rounded or heart-shaped as in C. nigrifrons; the hemitergal lobe is evenly tapering in lateral view, not like the medially abruptly tapering lobe in C. nigrifrons that could be observed both in dorsal and lateral aspects. Both of these characters were overlooked in previous studies (compare Sivec & Zwick 1989: fig. 3b and Figs 1, 3B, D–E vs Figs 6B–E, 8A–B)., Published as part of Mo, Rao-Rao, Liu, Rui-Jun, Wang, Guo-Quan, Li, Wei-Hai & Murányi, Dávid, 2021, Review of the genus Chinoperla Zwick, 1980 (Plecoptera: Perlidae: Perlinae) from China, pp. 62-85 in European Journal of Taxonomy 775 on pages 64-71, DOI: 10.5852/ejt.2021.775.1547, http://zenodo.org/record/5578472, {"references":["Banks N. 1939.

Chorion dark brown, covered with fine punctuations. Micropylar orifices sessile, much larger than punctuations, set on subequatorial line. Distribution Originally described from Tam Dao, Vietnam, and herein reported from China: Guangdong Province. Remarks The Chinese specimens are similar to the original description of Chinoperla gorohovi from northern Vietnam, in regards of head pattern, male terminalia, aedeagal tube, and the long apical spine of the aedeagal sac. However, the Chinese specimens differ in having two membranous dorsomedial lobes on the aedeagal sac (compare Fig. 12A–B with Sivec & Stark 2010: fig. 2). In the type specimens, the aedeagal sac apically has only one dorsal membranous lobe. In addition, the aedeagal sac of the Chinese specimens have an obscure, slightly sclerotized ventroapical patch, without a ventroapical spinose lobe, while in the type specimens, the aedeagal sac lacks the sclerotized ventroapical area, but has a short additional ventroapical spinose lobe. Unfortunately, the type specimens are permanently not available for study due to the re-organization of the Slovenian Museum of Natural History, Ljubljana (PMSL) collection (Ignac Sivec pers. com.)., Published as part of Mo, Rao-Rao, Liu, Rui-Jun, Wang, Guo-Quan, Li, Wei-Hai & Murányi, Dávid, 2021, Review of the genus Chinoperla Zwick, 1980 (Plecoptera: Perlidae: Perlinae) from China, pp. 62-85 in European Journal of Taxonomy 775 on pages 77-82, DOI: 10.5852/ejt.2021.775.1547, http://zenodo.org/record/5578472, {"references":["Sivec I. & Stark B.

Redescription Male ADULT HABITUS (Figs 6A–B, 8C, 9A). General color brown. Forewing length 7.7–8.0 mm, hindwing length 6.7–7.1 mm. Head brownish, with a dark brown heart-shaped spot, but specimens from Mount Yinggeling with a long brown band located on the occiput, and with a subtriangular dark brown spot in front of M-line; biocellate, ocelli about 3 diameters apart of each other, slightly closer to each other than to the compound eye; antennae brown. Pronotum trapezoidal, brown with paler lateral margin and with darker, distinct rugosities; anterior corners pointed but posterior corners obtuse. Legs generally brown, proximal part of femora mostly lighter; wings subhyaline and brownish, veins brown, Sc of forewing short, typical of the genus (Fig. 8C); cerci brownish. ABDOMEN (Figs 6C–E, 8A–B, 9B–E). Sterna 3–5 with hair brushes. Dark median sclerite of tergum 9 trumpet-shaped, about half as long as the segment, heavily sclerotized, distinctly forked distally with two sharp points. Hemitergal processes slender, about 2.5× as long as basal width, distinctly narrowing subapically; medially indented in lateral view; basal callus fully covered by sensilla basiconica. AEDEAGUS (Figs 7, 10). Aedeagal tube partially sclerotized dorsally, forming a distinctly T-shaped marking on the holotype (Fig. 7A–B), but marking in specimens from Mount Yinggeling indistinct, well seen only in lateral view (Fig.10A–B). Fully everted sac as long as the tube, curved dorsad; ventroapical and dorsoapical surface heart-shaped in specimens from Mount Yinggeling (Fig. 10), less definite in the holotype (Fig. 7); dorsoapical surface with a small bulgy membranous median lobe; a single large spine about as long as ¼ aedeagus length, and a large membranous lobe medially at apex, slightly directed dorsally; ventral surface with a large basal patch of spinule, and one long and one shorter subapical spines (Fig. 7) but in fresh specimens from Mount Yinggeling the two of approximately equal length (Fig. 10); lateroapical part with dense, large and curved spines arranged on each side. Distribution China: Hainan Province, found in three counties. Remarks We carefully compared the type specimens of O. nigrifrons deposited in MCZ with the illustrations in Sivec & Zwick (1989). The head pattern, direction of antennae and shape of the pronotum of the female paratype collected on 13 July 1935 are consistent with those illustrated in Sivec & Zwick (1989: fig. 3a, d–e). The figures of the terminalia and vagina also refer to the same female paratype, because the second female paratype collected on 2 August 1935 had not been dissected, and its sternum 9 is more narrow. The figure of the male terminalia in Sivec & Zwick (1989: fig. 3b) shows a shallow apical notch of the median sclerite of tergum 9, and tapering and curving hemitergal processes without a straight apical half. These characters are consistent with those in the male paratype, that is not conspecific with the holotype and has been reassigned to C. changjiangensis sp. nov. above (Fig. 3B–E). However, the small basal sclerite in the aedeagus of the holotype (Fig. 7B) corresponds to that illustrated in Sivec & Zwick (1989: fig. 3c). Therefore, we believe that the half-everted aedeagus of the holotype, the terminalia of the male paratype (C. changjiangensis sp. nov.), and the head, pronotum, sterna 7–9 and vagina of the female paratype of Chinoperla nigrifrons were redescribed by Sivec & Zwick (1989). Color photographs and illustrations of the male holotype are provided in the present study (Figs 6–7). The characteristics of both female paratypes agree well with the description and illustrations provided by Sivec & Zwick (1989). We checked the types of S. furcomacula in IZCAS, but the aedeagus of S. furcomacula with the holotype label was difficult to fully evert due to the poor condition of the specimen. Based on the original description and redescription of C. nigrifrons in the present study, we believe that the holotype of S. furcomacula is conspecific with the holotype of O. nigrifrons, and is therefore a junior synonym of C. nigrifrons (Banks 1939; Wu 1973; Sivec et al. 1988; Sivec & Zwick 1989). The two recently collected males from Hainan Province examined in this study agree well with the type specimens in general characteristics such as head pattern, lateral aspect of the hemitergal lobes, and armatures of the aedeagus. However, these fresh specimens from Mount Yinggeling show slight differences in the head pattern and aedeagus, as they have a long brown posterior band on the head, and the two ventroapical spines of the aedeagal sac are straight and nearly equal in length. We believe this brown occipital band disappears in fully aged adults, such as the holotype. Similar differences were documented in the case of Kamimuria guangxia Li & Wang, 2013 and Neoperla lihuae Li & Murányi, 2014 (Wang et al. 2013; Li et al. 2014). The differences in the aedeagal armatures can be regarded as intraspecific differences. We provide illustrations of the fully everted sac of the C. nigrifrons holotype and the fresh adults to allow a reliable identification for future studies (Figs 7, 10). Unfortunately, the paratype female of S. furcomacula in IZCAS is badly damaged and difficult to study. According to the original description and figures of S. furcomacula (Wu 1973: fig. 93), the terminalia of the paratype female distinctly differ from those of C. nigrifrons by the unmodified subgenital plate. Sivec & Zwick (1989) drew up three possibilities for the specific identity of this female; we support the third, which suggests that the paratype female may not be conspecific with the holotype of S. furcomacula. Further specimens from Hainan are needed to confirm the identity of the female., Published as part of Mo, Rao-Rao, Liu, Rui-Jun, Wang, Guo-Quan, Li, Wei-Hai & Murányi, Dávid, 2021, Review of the genus Chinoperla Zwick, 1980 (Plecoptera: Perlidae: Perlinae) from China, pp. 62-85 in European Journal of Taxonomy 775 on pages 71-77, DOI: 10.5852/ejt.2021.775.1547, http://zenodo.org/record/5578472, {"references":["Banks N. 1939.

Neoperla annulatispina Mo, Li & Wang, sp. nov. (Figs. 1–2) Adult habitus (Fig. 1). Body color generally dark brown, abdomen pale. Head pale, with a prominent dark brown rectangular ocellar patch, and a smaller, semicircular spot interrupted by M-line; palpi brown; antennae generally brown, basal part paler; biocellate, the distance between ocelli ca. 2.0 X as wide as the diameter of the ocellus; head slightly wider than pronotum. Pronotum dark brown and rectangular, with scattered, dark rugosities and a pair of pale lateral areas; corners rounded. Wings brownish and transparent, veins dark brown; legs dark brown, basal two third of femora pale (Fig. 1e); cerci pale. Male (Figs. 1b–1d, 2a–2e). Forewing length 11.0– 12.4 mm (N=3). Tergum 6 with a posteromedial patch of sensilla basiconica. Tergum 7 with an anteromedian pair of sclerotized, upraised, nipple-shaped processes and a distal rectangular process on posterior margin covered with sensilla basiconica. Tergum 8 with a recurved triangular process, fringed with small distal spines. Tergum 9 with two paramedial patches of long hairs. Hemitergal processes of tergum 10 upcurved, finger-like. Aedeagus mostly membranous, falciform (Figs. 2a–2e). Aedeagal tube mostly straight, only dorsal surface sclerotized (Figs. 2a, 2c–2d). Aedeagal sac slightly longer than tube and curved ventrally, forming a right angle to tube; dorsolateral surface with 2–3 irregular rows of small spines; subapical portion with a complete ring of small spines; apical surface densely covered with tiny spinules; apical portion with a H-shaped, dark uneverted flagella (Figs. 2a–2e). Female (Figs. 2f– 2g). Forewing length 13.0– 14.5 mm (N=2). Habitus generally similar to male except dark brown marking on head is more extensive. Sternum 8 lightly sclerotized; the posteromedial margin slightly produced forming a small quadrate sclerotized subgenital plate. Eggs. Available females were void of matured eggs. Type Material. Holotype: male (HIST), China: Guangdong Province, Shaoguan City, Chebaling National Nature Reserve, Xiba, N 24°43’48”, E 114°15’36’’, 360 m, 2016.V.1, light trap, Luo, Liu, Xun & Zhao. Paratypes: 1 male and 1 female (CAU), 1 male and 1 female (HIST), same locality and date as holotype. Etymology. The specific name refers to the ringed section of small spines of aedeagus. Latin “annulatus” means ringed and “spina” means spine. Distribution. China: Guangdong, Chebaling National Nature Reserve (Fig. 15). The exact habitat is unknown. Remarks. The new species is a member of the Neoperla montivaga species group (Zwick 1983). The new species shares similar head pattern, terminalia and aedeagus with N. nigromarginata Li & Zhang, 2014 known from Henan Province of Central China. However, the new species can be separated from the latter by the following features: the paired lateral pale area of pronotum is smaller; aedeagal sac only with 2–3 irregular rows of small spines in dorsolateral surface; subapical spinous ring is complete; paired apical flagella is linked by a short sclerotized band. In N. nigromarginata, the paired lateral pale area of pronotum is bigger, comprising about 50% of the total surface; aedeagal sac with 2–3 irregular rows of small spines in dorsal surface and a large lateral patch of small spines, without subapical spinous ring or the ring is not complete; paired apical flagella are not connected. In addition, subgenital plate of female sternum 8 of N. nigromarginata has a small median notch at posterior margin, while the subgenital plate of the new species lacks a median notch. The COI sequence of Neoperla annulatispina Mo, Li & Wang, sp. nov. and N. nigromarginata had a consistent length of 659 bp, and both biased toward A and T nucleotides (N. annulatispina: 26.0% A, 21.3 C, 18.6% G and 34.1% T; N. nigromarginata: 26.3% A, 21.7 C, 18.1% G and 34.0% T). The genetic distances were calculated for the 16 sequenced specimens (Table 2). In our study, pairwise distances of the two Neoperla species were 2.0–2.8%; with an average of 2.3%, slightly higher than 2% threshold considered for a rough differentiation between intraspecific and interspecific distances (Hebert et al. 2003; Zhou et al. 2009). The minimum and average interspecific sequence divergences of the two species are higher than the maximum intraspecific sequence divergences (0.6–1.1%) without overlap (Table 2). In the Neighbor-joining (NJ) tree (Fig. 3), male and female specimens of N. annulatispina are grouped in the same clade, separated from the clade of male and females of N. nigromarginata. The combination of morphology and molecular data suggest that N. annulatispina is a new species to science.

Neoperla similidelphina Mo, Li & Murányi, sp. nov. (Figs. 11–14) Adult habitus (Fig. 11). Body color generally brown. Head pale, with a dark brown subtriangular spot on frons and a dark brown subtriangular ocellar patch; palpi brown; antennae generally brown, scape darker; biocellate, the distance between ocelli ca. 2.0 X as wide as the diameter of the ocellus; head slightly wider than pronotum. Pronotum pale brown and rectangular, with scattered, brown rugosities and dark midline; corners rounded. Wings brownish and transparent, veins brown; legs brown; cerci pale. Male (Figs. 11b–11d, 12). Forewing length ca. 12.3 mm. Tergum 7 with a trapezoidal posteromedial process covered with sensilla basiconica. Tergum 8 with an erect tongue-shaped process, fringed with small distal spines. Tergum 9 with two paramedial patches of long hairs. Hemitergal processes of tergum10 up-curved, finger-like. Aedeagus mostly membranous, hook-like (Fig. 12). Aedeagal tube mostly straight, only dorsal surface sclerotized; ventroapically with an erect, medially bifurcated Y-shaped lobe; arms of the lobe are without spines and as long as stalk of the lobe. Aedeagal sac slightly longer than tube, curved ventrally and forming an open loop, fully covered with brown spines, spines are larger but scarcer dorsoapically; apical part gradually tapering to a nipple-like tip. Female (Fig. 13). Forewing length ca. 14.5 mm. Habitus generally similar to male. Sternum 8 slightly sclerotized in most parts; posteromedial area strongly sclerotized, produced into a short but distinct subtriangular subgenital plate with a shallow posterior notch. Eggs (Fig. 14). Length 363–373 μm, width 213–215 μm (N=6). Elongate oval in shape with 78–82 outer striae connecting collar and lid; striae set closely with fine sulci between them. Hatching line inconspicuous. Micropyles sessile, dispersed between striae, set on subequatorial line. Collar and lid sessile without distinct flange, lid slightly wider than collar; both surrounded by two rows of regular follicle cell impressions (FCIs) at junction of striae and fully covered with fine punctations; anchor not studied. Type Material. Holotype: male (HIST), China: Guangxi Zhuang Autonomous Region, Guilin City, Xing’an County, Maoershan National Nature Reserve, Grand Canyon, N 25°51’ 27’’, E 110°28’0”, 523 m, 2020.VI.20, light trap, Mo, Lai et al. Paratype: 1 female (HIST), same locality and date as holotype. Etymology. The specific epithet refers to the similarity to the closely related species, Neoperla delphina Li, Mo & Wang, 2020. Distribution and ecology. China: Guangxi, Maoershan National Nature Reserve (Fig. 15). The type locality is the same river in Maoershan where N. chebalinga was collected. Remarks. The new species is assigned to the Neoperla diehli subgroup of N. montivaga species group (Mo et al. 2020b, Zwick 1983, Zwick & Sivec 1985). It is most similar to N. delphina Li Mo & Wang, 2020 which is known from Guangxi. Both species share similarities in male terminalia and aedeagal structure. It may be separated from N. delphina by its head pattern lacking a distinct posterior notch, by the aedeagal tube having a straight Y-shaped lobe in lateral view, by the aedeagal sac being fully covered by tiny spines and with a nipple-shaped tip. In N. delphina, the head pattern has a triangular posterior notch; the apical half of Y-shaped lobe of aedeagal tube is strongly curved backward; the aedeagal sac is covered with tiny spinules only in the apical half, and in having a finger-like tip. The female subgenital plate of the new species is short and subtriangular with a small posteromedial notch, while in N. delphina, the female subgenital plate is longer, triangular, and with an obscure apical emargination., Published as part of Mo, Raorao, Wang, Ying, Wang, Guoquan, Li, Weihai & Murányi, Dávid, 2021, Two new species and three new provincial records of Neoperla (Plecoptera: Perlidae) from Nanling Mountains, China, pp. 195-214 in Zootaxa 5040 (2) on pages 206-211, DOI: 10.11646/zootaxa.5040.2.2, http://zenodo.org/record/5531145, {"references":["Mo, R.
