This species differs from other species of the genus by the combination of: elytra with metallic green lateral stripes, elytra disc reddish brown with metallic hue, postgenae without suborbital setae, and males with rudimentary adhesive setae on mesotarsomere 1. It is most similar to P. latecincta, with both having metallic green lateral stripes on the elytra. However, P. circumdata is readily differentiated from the latter species in having the elytra lateral stripes narrower, only extended medially to interval 7 in the middle, elytra disc with distinct metallic hue, and males with adhesive setae ventrally on mesotarsomere 1. Description. Body length 10.0–11.0 mm. Head and pronotum dark brown, with faint metallic green hue; mouthparts yellowish brown, apices of mandibles dark brown; basal four antennomeres reddish brown, apical ones distinctly darker; elytra disc reddish brown, with distinct metallic purple hue, with narrow metallic green lateral stripes, extended medially over intervals 8 and 9 and half of interval 7 at middle, stripes narrowly continuous at base, nearly extended to sutural angles at apex, interval 1 completely brown; elytral lateral margins and epipleura brown with strong metallic hue; legs dark brown, apices of femora piceous with metallic green hue; venter dark brown. Vertex finely and densely punctate; postgenae without suborbital setae; antennae barely extended to pronotal base; labrum quadrate, apex nearly straight; mentum with a pair of minute median setae, barely visible in some specimens. Pro notum sub-cordate, PW/PL = 1.35–1.43, usually slightly wider than head, PW/HW = 0.99–1.04; widest at anterior third, strongly narrowed to base, more or less sinuate before posterior angles; posterior angles widely obtuse; disc usually with sparse punctures. Elytra slightly dilated to apex, with shallow isodiametric microsculpture; striae well incised, with fine puncture rows; intervals sparsely punctate; disc with large shallow depressions near basal third of intervals 3 to 6. Males with uniseriate adhesive setae near apex of mesotarsomere 1, with biseriate setae on apical half of mesotarsomere 2 and almost full length of mesotarsomere 3. Apex of abdominal sternite VII nearly straight in males. Median lobe of aedeagus stout (AL/AW = 3.9–4.1), right margin weakly pointed before apical lamella; apical lamella thick, ovate in dorsal view, LL subequal to LW, not declined to left; subuliform in lateral view, apex not bent upward. Endophallus with very large flared basal expansion of primary sclerite; flagellum extending almost to the base of apical orifice; apical sclerite narrowly V-shaped, weakly defined, basal core indistinct; basal sheath coarsely scaled, apical sheath finely scaled, similar size as basal sheath; squamate sac well divided, near middle of median lobe, dorsal-right to squamate sheath; distal sac smaller and closer to apex than proximal sac. Gonocoxite II of ovipositor nearly trapezoid, slightly longer than width, apex curved, angulate near inner apical angle, with two ensiform setae on outer apical angle, three on inner apical angle, one of them slightly distant from other two.

2. Parena laesipennis species group This species group contains three very similar and allopatric species, distributed from East Asia to western part of Indonesia, but not known from south India or islands east of the Wallace line (Map 3). This species group is characterized by: dorsal surface entirely yellowish brown to reddish brown; elytral striae not incised, replaced by lines of punctures, intervals flat; elytral sutural angles more or less pointed, forming short spines, outer apical angles more or less angulate; LL much bigger than LW., Published as part of Shi, Hongliang & Liang, Hongbin, 2023, Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina), pp. 1-144 in Zootaxa 5286 (1) on page 32, DOI: 10.11646/zootaxa.5286.1.1, http://zenodo.org/record/7958937

[29] Parena (Parena) amamiooshimensis Habu, 1964 Habitus: Fig. 59C. Male genitalia: Fig. 61. Habu, 1964a: 29 (type locality: Amami-oshima Is., Hatsuno, holotype in NIAES: National Institute for Agro-Environmental Sciences, Japan); Habu, 1967: 156; Habu, 1982: 113. Type material examined. Parena amamiooshimensis Habu: Paratype: 1 male (NHML), "Paratype" [round label with yellow circle], " Amamiôshi- / ma Is., Kago- / shima Pref. / Japan ", "Paratype / Parena / amamiooshi- mensis Habu " [green label] . Comparisons. This species is very similar to P. nigrolineata, but its stout male genitalia shows they are distinct. Externally, P. amamiooshimensis differs from P. nigrolineata mainly in having the elytra black stripes obliterated from the apices and background color darker. According to Habu (1967), these differences are valid when determining Japanese species. However, we examined one specimen of P. nigrolineata from Guizhou, China (Fig. 56E) having elytral stripes similar to P. amamiooshimensis, and two specimens of P. nigrolineata from Yunnan having dark reddish brown background similar to P. amamiooshimensis. Thus, distributional information is sometimes necessary when identifying this species. Description. Body length 8.0– 9.3 mm. Dorsum dark reddish brown, elytra with black lateral stripes, without metallic hue, stripes completely or partly obliterated from intervals 1 to 4 basally and apically; antennae, mouthparts, legs and venter brown. Postgenae without suborbital setae; antennae hardly reaching pronotal base; mentum with a pair of very short median setae. Pronotum rounded-hexagon, PW/PL = 1.43–1.49, slightly wider than head, PW/HW = 1.04–1.08; widest at anterior third, strongly narrowed to base, lightly sinuate before posterior angles; posterior angles widely obtuse. Elytra slightly dilated to apex, surface with very faint isodiametric microsculpture; striae well incised, with fine puncture rows; intervals sparsely punctate; disc with large and shallow depressions near basal third of intervals 3 to 6. Apex of abdominal sternite VII weakly emarginate in males. Median lobe of aedeagus stout, right margin sinuate before apical lamella; apical lamella wide rounded-triangular, LL smaller than LW, apex weakly bent upward in lateral view. Females not studied, but according to Habu (1967) gonocoxite II of ovipositor similar to P. nigrolineata. Distribution (Map 10, cyan). Only known from the Ryukyu Islands, including Takera Is., Amami Is., Okinawa Is., Tokuno Is. and Ishigaki Is. (Habu, 1967, 1982). It is sympatric with P. nigrolineata. Remarks. P. amamiooshimensis is a species with the stoutest male genitalia within the P. nigrolineata group, which is somewhat similar to the P. latecincta group. However, the male genitalia of P. amamiooshimensis is different from that of P. latecincta group in the apical lamella (in lateral view) thin and apex slightly bent dorsally. This character well corresponds to other species in the P. nigrolineata group., Published as part of Shi, Hongliang & Liang, Hongbin, 2023, Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina), pp. 1-144 in Zootaxa 5286 (1) on page 103, DOI: 10.11646/zootaxa.5286.1.1, http://zenodo.org/record/7958937, {"references":["Habu, A.

", "Kashitu. 2.15, from umbel flower of tree" . Comparisons. P. africana can be readily distinguished from other African species of Parena by the combination of elytra mainly black with brown apical margin or entirely brown; antennae distinctly bicolor; tarsi same color as tibiae; postgenae without suborbital setae; pronotum with lateral margins strongly sinuate before posterior angles; elytral sutural angles not pointed. There are two very different color forms in this species. The pale form is externally very similar to P. ferruginea, and the dark form is similar to P. plagiata and P. scutata. The differences between P. africana and those three species are provided under each of them, respectively. Description. Body length 7.3–10.4 mm. Dorsum reddish brown, moderately polished; elytra color dimorphic: entirely reddish brown (Fig. 80D) or mainly black with narrow red apical margin, red area occupied apical tenth to eighth of elytra, disc without central red patch (Figs 80C, 80E, 80F). Antennae distinctly bicolor: basal four antennomeres reddish yellow, apical ones nearly black. Scutellum reddish brown; venter reddish brown; legs uniformly reddish brown. Vertex with sparse fine punctures; postgenae without suborbital setae; mentum with a pair of median setae, which are shorter than terminal labial palpomere; antennae extended to pronotal base. Pronotum sub-cordate, PW/PL = 1.32–1.46, subequal width as head, PW/HW = 0.97–1.07; widest at anterior third, lateral margins evenly rounded before middle, strongly sinuate before posterior angles; posterior angles rounded-obtuse, not prominent; lateral explanations slightly wide; disc finely wrinkled and punctate near median line. Elytra slightly dilated to apex; with isodiametric microsculpture, usually very shallow; striae faintly incised on apical half, with rows of fine punctures; intervals faintly convex, with fine punctures; discal depressions shallow, nearly triangular, occupying intervals 3 to 6, less than one-third of elytra length; elytral apices well rounded, sutural angles not pointed. Males with biseriate adhesive setae on apical half of mesotarsomere 1 and almost full length of mesotarsomeres 2–3. Apex of abdominal sternite VII straight, with two setae on each side in both sexes. Median lobe of aedeagus slenderer than the previous species (AL/AW = 4.5–4.8), ventral margin nearly straight at middle; apical lamella slightly thick, LW slightly greater than LL, apex rounded; in lateral view, apical lamella slightly bent upward. Endophallus with very widely flared basal expansion of primary sclerite; flagellum extending almost to base of apical orifice; apical sclerite widely V-shaped, well-defined, basal core distinct, small and strongly scaled; basal sheath coarsely scaled, apical sheath finely scaled, slightly larger than basal sheath; squamate sac divided, dorsal to squamate sheath; proximal sac large and dorsal-ventrally compressed, distal sac much smaller than proximal sac, closer to apex. Gonocoxite II of ovipositor nearly quadrate, length subequal to basal width, apex concave, inner apical angle strongly pointed; with two or three ensiform setae on outer apical angle, three on inner apical angle. Distribution (Map 14, blue). Widely distributed in Sub-Saharan African continent. Known from the following counties: Cameroon, Senegal, Nigeria, the Central Africa Republic, Gabon, Uganda, Tanzania, Zambia. Remarks. P. africana is the most common and widespread Parena species in the African continent.After studying materials with dark and pale elytra from several localities, we found that these two forms with entirely different elytra colors belong to the same species. Aside from their different elytral color, they are identical in pronotal shape, elytral apices, microsculpture, antennal color, and, most importantly, the male genitalia (Fig. 82). We examined a total of 37 specimens, nine of which were of the pale form (marked by an asterisk in the citations of examined materials) and the other 28 of the dark form. The pale form of P. africana might be confused with several other species without a distinct elytra color pattern. Within subgenus Parena, ten species have uniform elytral color, which varies from reddish yellow to dark brown. All members of seven of these have monochromatic elytra, but the other three species are pleomorphic, with only a few individuals having the yellowish-brown unicolorous form. These ten species are classified into several different species groups, but their similar external appearances make their identification troublesome. To facilitate the identification of specimens of these species, we provide a key to species in the subgenus Parena with uniformly yellowish brown elytra., Published as part of Shi, Hongliang & Liang, Hongbin, 2023, Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina), pp. 1-144 in Zootaxa 5286 (1) on pages 137-139, DOI: 10.11646/zootaxa.5286.1.1, http://zenodo.org/record/7958937, {"references":["Alluaud, C.

Rai", "Pothana / 1900 m / 7-9.VI.84", " Parena / obscura / Det. Sciaky '95" . Comparisons. This species is very similar in several aspects to P. tesari, especially to specimens of that species from Yunnan and Vietnam. These two species differ mainly in the characters of male genitalia: in P. obscura, apical lamella very short, LL half as LW, endophallus with flared basal expansion strongly bent and basal sheath reduced (Fig. 35); in P. tesari, apical lamella much longer, LL subequal to LW, endophallus with flared basal expansion straight and basal sheath well-developed (Fig. 33). These two species also differ as follows: P. obscura has longer tempora, with the length of tempora plus neck-constriction about the same as length of the eye, and P. tesari has shorter tempora, with the length of tempora plus neck-constriction about two-thirds of the length of the eye. Description. Body length 11.0– 11.2 mm. Dorsum piceous, tarsi, antennae, and mouthparts distinctly lighter than body. Tempora gradually narrowed behind eyes, length of tempora plus neck-constriction subequal to diameter of eye; vertex with a pair of short additional setae posteromedial to the primary posterior supraorbital seta; mentum with a pair of short setae. Pronotum nearly quadrate, PW/PL = 1.20–1.21, distinctly narrower than head, PW/HW = 0.85; lateral explanations narrow; widest at anterior third, slightly rounded at anterior half, and then clearly sinuate before posterior angles; posterior angles nearly rectangular and slightly pointed outward. Elytra wide, slightly dilated to apex, surface without microsculpture; striae not incised, replaced by fine puncture rows; intervals flat, with fine and sparse punctures; interval 3 with three setigerous pores; apical truncation indistinct, evenly rounded, sutural angles indistinct. Apex of abdominal sternite VII with three setae on each side. Males with uniseriate adhesive setae on apical three-fourths of mesotarsomere 2 and biseriate adhesive setae on nearly full length of mesotarsomere 3. Median lobe of aedeagus slender (AL/AW = 5.0), apical lamella laminar, LL half of LW, apex rounded. Endophallus with relatively small primary sclerite, flared basal expansion strongly bent, apical flagellum very short, ending at basal third of median lobe; apical sclerite elongate and well defined, basal core ovate; basal sheath reduced to fine scales surrounding flagellum, apical sheath composed of two scaled regions; squamate sac not divided, large and square, near middle of median lobe, right to squamate sheath. Female unknown, but inferred to have an ovipositor similar to that of P. tesari. Distribution (Map 7, red).

Shi H.L. 2022" [red label] . Diagnostic characters. Dorsum pale yellow, pronotum with a pair of dark stripes, elytra with a pair of short basal stripes and a pair of well separate subapical spots; labrum slightly dilated to apex, apex strongly emarginate; antennae extended only slightly beyond elytral base; elytra intervals with very sparse fine punctures. Comparisons. The new species is different from all other species of the genus Parena by the apex of labrum strongly emarginate (Fig. 46C). Several other species of the P. tripunctata group have the labrum apex very weakly emarginate, but the labrum apex is straight or slightly curved in all other species groups of the genus. The elytral color pattern of the new species is similar to some individuals of P. taiwana with four spots. However, the new species can be easily distinguished from P. taiwana by: labrum apex emarginate; pronotum with a pair of dark stripes; elytral intervals without dense punctures; and antennae shorter, extended beyond the elytra base by the length of only one antennomere. Description. Body length 6.3–6.7 mm; body relatively narrow for the genus; dorsum without microsculpture. Color. Dorsum mostly pale yellow to light brown; head yellowish brown, vertex with indistinct dark brown patch, mouthparts and antennae yellow, apices of mandibles dark. Pronotum disc with a pair of dark stripes aside median line, not extended to anterior or posterior margins. Elytra with four black patches: a pair of short stripes slightly distant from elytra base, about one-fifth as long as elytra, extending from outer half of interval 4 to inner half interval 6; another pair of round spots near apical third of elytra, extending from outer half of interval 3 to inner half of interval 5. Scutellum, epipleura, legs and venter yellow. Head with sporadic fine punctures on vertex and occiput; eyes large and strongly prominent; tempora short, abruptly narrowed behind eyes, length of tempora plus neck-constriction approximately one-third of diameter of eye; postgenae with a pair of suborbital setae, as long as supraorbital setae. Antennae extended beyond elytral base by length of only one antennomere. Labrum slightly dilated to apex, apex strongly emarginate; mandibles short and wide; mentum with a pair of long median setae, lateral lobes short, apex narrow, inner margins strongly oblique, outer margins rounded, epilobes rather wide. Pronotum nearly rectangular, PW/PL = 1.35–1.37, about same width as head, PW/HW = 1.00–1.03, widest at anterior third, lateral explanations slightly wide; lateral margins fully rounded at anterior half and then narrowed to base with distinct sinuation before posterior angles; posterior angles weakly pointed outwards, forming rectangular angles with rounded apex; anterior margin nearly straight at middle; posterior margin oblique at sides; disc convex, with very fine transverse wrinkles. Elytra weakly convex, slightly dilated to apex. Striae very shallowly incised at basal half, almost flat at apical half, with rows of fine punctures on basal five-sixth, punctures absent from apical sixth; intervals weakly convex, with very sparse fine punctures. Disc without depression, lateral sides slightly depressed near anterior third. Elytral basal pore present at base of stria 1; interval 3 with three discal setigerous pores: first one on a level much behind scutellar apex, adjacent to stria 3; second one slightly before middle, adjacent to stria 3; third one on apical eighth, adjacent to stria 2; interval 9 with 23–24 umbilicular pores. Apical truncation indistinct, evenly rounded, sutural angles indistinct. Venter. In females, apex of abdominal sternite VII straight, with two setae on each side. Female genitalia. Gonocoxite II of ovipositor rounded rectangle, basal width much greater than length, apex straight, with five or six very short ensiform setae nearly evenly arranged. Male unknown. Distribution (Map 8, dark green). China (Sichuan, Xizang). Only known from two specimens from well separated localities. Etymology. The scientific name of the new species " emarginata " is derived from Latin referring to its labrum apex strongly emarginate, which is the unique character of this species. Remarks. The holotype was collected in a sparse riparian forest, about six meters high in the canopy, using a long-stick sweep net., Published as part of Shi, Hongliang & Liang, Hongbin, 2023, Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina), pp. 1-144 in Zootaxa 5286 (1) on pages 78-79, DOI: 10.11646/zootaxa.5286.1.1, http://zenodo.org/record/7958937

Parena shapingensis Xie & Yu : Holotype (IZAS, Fig. 40A): male, body length = 6.5 mm, board mounted, " Shaping / 27.IX.1943 " [in Chinese], " HOLOTYPE " [red label], " Parena shapingensis / Xie et Yu / Xie Weiping det. 1991", "IOZ(E) 211403" [blue label] . Notes on types and synonyms. Parena shapingensis Xie & Yu : The holotype of this species is briefly labeled as "Shaping, 27.IX.1943 " in handwritten Chinese without other explanation of this locality. In the original description, the type locality was explained as Guangdong (Shaping), referring to Shaping town of Heshan city. However, this speculation could be wrong because Guangdong is far from all other known localities of this species. The handwriting of the locality label is identified that of a famous Chinese entomologist, Prof. Sicien Chen. He worked in Academia Sinica in Chongqing from 1939 to 1946. Thus the type locality "Shaping" is very likely to refer to Shapingba (N29°32' E106°27') in Chongqing City. Parena yunnana Kirschenhofer : We did not examine the type of this species, but the specimens from very close to its type locality that we examined are perfectly in accord with the original description and illustration of P. yunnana. So, we confirmed that P. yunnana is identical to P. shapingensis in external and male genital characters. Non-type material examined. 1 female (HBUM), " Sichuan, Lixian, Shangmeng, 2009.VII.24–25, Gao ZH., Niu YP. lgt.". 1 male (IZAS), " Yunnan, Lijiang, Yulongshan, 1979.VIII.12, Zou Huanguang leg." . 1 male (CRS), " China Yunnan, 1800 m, Lijiang 23.6–21.7, 26.53N 100.18E, lgt. S. Becvar 1992". 1 male (IZAS), " Kunming, World Horticultural Expo Garden, 2004.6.27, Ou Xiaohong lgt.". Comparisons. This species is easily distinguished from all other species of subgenus Bothynoptera by the small size and elytra light yellowish brown with an indistinct large pale patch. The male genitalia of this species are very similar to those of P. tripunctata, but differ in the ventral margin of median lobe, which is nearly straight, and the apical lamella not bent dorsally. Description. Body length 6.5–6.7 mm. Head and pronotum yellowish red; elytra gradually graded from yellowish brown basally to pale yellow subapically, apical eighth of elytra yellowish red, forming a vague, large pale patch on the middle of elytra; legs, antennae, and mouthparts yellowish brown; venter yellowish brown. Labrum slightly dilated to apex, apex very weakly emarginate. Pronotum nearly cordate, PW/PL = 1.26–1.36, slightly narrower than head, PW/HW = 0.93–0.97; lateral explanations narrow; widest at anterior third, well rounded at anterior half, and then strongly sinuate before posterior angles; posterior angles nearly rectangular with distinct apex, slightly pointed outward. Elytra slightly dilated to apex, surface without microsculpture; striae shallowly incised, with fine puncture rows; intervals with very sparse punctures. Males with biseriate adhesive setae near apex of mesotarsomere 2 and apical two-thirds of mesotarsomere 3. Median lobe of aedeagus very stout, in dorsal view apex distinctly bent to right; in lateral view ventral margin nearly straight before middle; apical lamella thick and short, LL much smaller than LW, apex rounded-truncate; in lateral view apical lamella not bent dorsally. Endophallus with squamate sac partly divided. Female ovipositor not studied. Distribution (Map 8, magenta). China (Chongqing, Sichuan, Yunnan).

This species is clearly most similar to P. rubripicta. The two are distinguished from all other species in the genus by the combination of the following two characters: (1) elytra metallic; (2) postgenae with a pair of suborbital setae. Some individuals are superficially similar to P. pendleburyi or P. monticola in general appearance but can be readily differentiated by the presence of suborbital setae. Description. Body length 6.3–8.3 mm. Head and pronotum reddish yellow to dark brown; antenna reddish brown, antennomeres 5–11 same as basal four antennomeres or darker; elytra metallic green or bluish green, with copper lustre near apices in some specimens, elytra without red patch, interval 1 completely green, epipleura same color as abdomen; venter of head and prothorax same as dorsum, venter of mesothorax, metathorax and abdomen yellowish red or piceous; legs same color as pronotum, femora with apex darker in some specimens, metatibiae same color as abdomen. Postgenae with a pair of suborbital setae; antennae barely extended to pronotum base; labrum quadrate, apex very weakly protruded at middle; mentum with a pair of short median setae. Pronotum nearly quadrate, PW/PL = 1.26–1.41, nearly same width as head, PW/HW = 0.96–1.09; widest at anterior third, slightly rounded at anterior half, and then clearly sinuate before posterior angles; posterior angles widely obtuse. Elytra slightly dilated to apex, surface usually without or with very faint isodiametric microsculpture, with distinct microsculpture in a few specimens; striae very shallowly incised, with fine puncture rows; intervals weakly convex, very sparsely punctate; disc with shallow and large depressions near basal third of intervals 3 to 6. Males with biseriate adhesive setae on apical half of mesotarsomere 1, and most of length of mesotarsomeres 2 and 3. Apex of abdominal sternite VII weakly emarginate in males. Median lobe of aedeagus slightly slender (AL/AW = 4.7–5.2), gradually narrowed to apex, ventral margin nearly straight; right margin very weakly sinuate before apex in dorsal view; apical lamella wide and short, apex rounded, weakly bent upward in lateral view. Endophallus with primary sclerite linear, without flared basal expansion; apical flagellum ending before middle of median lobe; apical sclerite narrowly V-shaped, strongly chitinized, basal core distinct, elongate, right to the major part of apical sclerite; basal sheath large, well scaled; apical sheath large and coarsely scaled; squamate sac large and well divided, near middle of median lobe, dorsal to squamate sheath; proximal sac strongly chitinized at apex, forming a dentate semicircular piece; distal sac file-like, smaller than proximal sac, much closer to apex than proximal sac. Gonocoxite II of ovipositor nearly quadrate, same length as basal width, apex strongly concave, with three ensiform setae on inner apical angle, and two on outer apical angle. Distribution (Map 9, red). Java, Sumatra, Sulawesi, The Philippines. This species was recorded from China (Anhui) by Xie & Yu (1993). After examining the specimen, we found that their record was based on a misidentified specimen of P. monticola. Geographical variation. This species is known from four regions of the Malay Archipelago. Specimens from different localities are different in the following aspects. (1) Elytra color. Elytra are generally metallic green (Fig. 50A) but slightly different in some specimens. For all examined specimens from the Philippines and a few from Sumatra, the elytra are bluish green (Fig. 50C); for some other specimens from Sumatra, the elytra have bright copperish lustre near the apices (Fig. 50B), giving them an appearance very similar to P. pendleburyi. (2) Color of venter, including mesothorax, metathorax, abdomen, epipleura, and metatibiae. These parts are always in the same color in any one specimen. They are piceous in specimens from Java and Sumatra (Fig. 50B), and red in those from Sulawesi and the Philippines (Fig. 50C). (3) Color of antennae. In most specimens, the antennae are completely reddish brown or apical the seven antennomeres slightly darker (Fig. 50B). However, for the two examined specimens from the Philippines, antennae are distinctly bicolor with the basal four antennomeres reddish brown and apical seven black (Fig. 50C). (4) Elytra microsculpture. The elytra are without or with very faint isodiametric microsculpture in specimens from most localities, but distinctly present in one female from Makassar examined., Published as part of Shi, Hongliang & Liang, Hongbin, 2023, Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina), pp. 1-144 in Zootaxa 5286 (1) on pages 86-89, DOI: 10.11646/zootaxa.5286.1.1, http://zenodo.org/record/7958937, {"references":["Motschulsky, V.

8. Parena tripunctata species group This species group contains eight species distributed mainly in East Asia. They are characterized by: body smallsized, length 6.4–9.1 mm; retinacular ridge of right mandible about one-third length of terebral ridge (Fig. 2E); mentum with a pair of long setae, longer than terminal labial palpomere; elytra with distinct pattern in most species; antennae extended slightly beyond elytra base; tempora short, abruptly narrowed behind eyes, length of tempora plus neck-constriction approximately one-third of diameter of eye; elytral intervals slightly convex, very sparsely punctate; interval 3 with three setigerous pores; elytral apices evenly rounded, sutural angles indistinct; males without adhesive setae on mesotarsomere 1; abdominal sternite VII with two pairs of setae in both sexes; median lobe of aedeagus very stout (AL/AW 3.3–4.0); gonocoxite II of ovipositor nearly rectangular or rounded-rectangular, apex with five to seven ensiform setae, nearly evenly arranged. The endophallus in this group is very similar among different species: primary sclerite with very wide flared basal expansion, its right-basal angle strongly pointed; flagellum short, ending before the middle of median lobe; apical sclerite widely V-shaped, well-defined, basal core distinct, large, ovate, heavily chitinized and scaled; basal sheath reduced to a triangular scaled structure left-ventral to flagellum; apical sheath large and coarsely scaled; squamate sac divided or undivided, near the middle of median lobe, right to squamate sheath. The species of this group are easily differentiated by their elytra pattern (see the key above), but it is difficult to find other differences on the external features besides the color. Their stout male genitalial shaft and endophallus are also similar in all the species. Although the shape of the apical lamella varies slightly individually in some species, differences in the apex and ventral margin of aedeagus can well define each species (except for P. emarginata sp. n. with male unknown). To interpret these differences better, we provide an alternate key for the male genitalia of this group. Key to species of P. tripunctata group by male genitalia 1.

Crossoglossa madagascariensis Alluaud : The original description mentioned three specimens from "Montagne d'Ambre", but no holotype was fixed. In the collection of MNHN, we found two males perfectly in accord with the original description. We herein designated the one with Alluaud's handwriting label as the lectotype. Parena alluaudi Jeannel : The original description mentioned one female from "Mahatsinjo". In the collection of MNHN we found one specimen perfectly in accord with the original description, but the holotype is a male. This specimen is very similar to the type of P. madagascariensis, except the color is slightly lighter. After examining the male genitalia of the holotype of P. alluaudi, we found that it is perfectly identical with P. madagascariensis (Figs 77, 78). Thus, we treat Parena alluaudi Jeannel as a junior synonym of Crossoglossa madagascariensis Alluaud herein. Non-type material examined. 1 female (MNHN), "Mars", "Mt. d'Ambre, Madagascar ", "MUSEUM PARIS MADAGASCAR, COLL A SICARD 1930", " Crossoglossa madagascariensis All. ". 1 female (NHMB), " MADAGASCAR C., Moramanga env., 10-18.xii.1997, P. Pacholatko leg." . Comparisons. This species can be readily distinguished from all other species of the subgenus Parena by the shape of elytral apices, which are distinctly truncate, with outer apical angles rounded-angulate and sutural angles forming sharp spines (Fig. 5D). For species of all other species groups in the subgenus Parena, the elytra apical margin is evenly curved with sutural angles not pointed (Fig. 5A). In the other three species of the P. scutata species group, the elytral apical margin is only moderately truncate, with the outer apical angles nearly rounded and sutural angles forming very small denticles (Figs 5B, 5C). P. madagascariensis is also different from the other three species of the same species group in having elytra without a dark pattern, elytra with shallow isodiametric microsculpture, and slightly larger size. P. madagascariensis is quite distinct from all other known species in the subgenus Parena but is externally similar to an Oriental species, P. kurosai, of subgenus Bothynoptera. These two species can be distinguished by differences in the position of the first elytral discal pore. Description. Body length 10.9–11.7 mm. Dorsum reddish brown to dark brown, moderately polished; antennae brown, apical antennomeres slightly darker than basal four ones; pronotal lateral explanations slightly lighter than disc; elytra without pattern; venter and legs reddish brown, tarsi slightly darker than tibiae. Vertex with fine punctures; postgenae without suborbital setae; mentum with a pair of median setae, which are the same length as terminal labial palpomeres. Pronotum sub-quadrate, PW/PL = 1.36–1.41, slightly wider than head, PW/HW = 1.01–1.08; widest at anterior third, lateral margins evenly rounded before middle, gradually sinuate before posterior angles; posterior angles widely rounded; lateral explanations wide; disc smooth, without punctures or transverse wrinkles. Elytra slightly dilated to apex; with shallow isodiametric microsculpture, visible only near base in some specimens; striae distinctly incised, very shallow near base, with fine puncture rows, punctures absent near elytral apices; intervals slightly convex, with sparse fine punctures; discal depression indistinct; apical truncation straight, outer apical angles prominent but apically rounded; sutural angles forming sharp spines. Males with biseriate adhesive setae on apical half of mesotarsomere 1 and full length of mesotarsomeres 2–3. Apex of abdominal sternite VII weakly emarginate in males, with two setae on each side in both sexes. Median lobe of aedeagus rather slender (AL/AW = 5.4–5.6), ventral margin straight near middle; apical lamella thin and narrow, oblong in dorsal view, LL much greater than LW, apex rounded; in lateral view, apical lamella slightly bent upward. Endophallus with very narrow flared basal expansion of primary sclerite; flagellum thick, extending near to the base of apical orifice; apical sclerite narrowly V-shaped, moderately defined, basal core distinct, small and moderately scaled; basal sheath very weakly scaled, apical sheath densely scaled, larger than basal sheath; squamate sac not divided, coniform, well chitinized, near middle of median lobe, ventral to squamate sheath. Gonocoxite II of ovipositor nearly quadrate, length subequal to basal width, apex strongly concave, inner apical angle strongly pointed; with four ensiform setae on outer apical angle, three on inner apical angle.

Durban", "H.E. Andrewes Coll., B.M. 1945.-97.", " Metallica formidulosa, Per. " . Comparisons. P. plagiata is distinguished among the African species of Parena by its unique elytra pattern: elytra with a very narrow red apical margin, inner intervals somewhat reddish at the middle, forming a vague central patch. This species is most similar to the dark individuals of P. africana in elytra pattern and the shape of elytral apices; but it differs from the latter species in: (1) elytral red apical margin much narrower; (2) elytral discal depressions more elongated; (3) lateral margins of pronotum less sinuate before posterior angles; and (4) median lobe of aedeagus stout, much stouter than in P. africana. Description. Body length 7.3–7.5 mm. Dorsum reddish brown, moderately polished; elytra mainly black, apices with very narrow red margin, less than one-twentieth of elytral length; inner four or five intervals slightly reddish, forming a vague central patch; antennae distinctly bicolor: basal four antennomeres reddish yellow, apical ones nearly black; scutellum reddish brown; venter reddish brown; legs uniformly reddish brown. Vertex with sparse fine punctures; postgenae without suborbital setae; mentum with a pair of median setae which shorter than terminal labial palpomere; antennae extended just beyond pronotal base. Pronotum trapezoidal, PW/PL = 1.39–1.41, subequal width as head, PW/HW = 0.98–1.00; widest at anterior third, lateral margins evenly rounded before middle, slightly sinuate before posterior angles; posterior angles rounded-obtuse, not prominent; lateral explanations slightly wide; disc finely wrinkled and punctate aside median line. Elytra slightly dilated to apex; with distinct isodiametric microsculpture; striae shallowly incised, with fine puncture rows; intervals slightly convex, with fine punctures; discal depressions elongate, occupying intervals 3 to 6, near half of elytra length; apices well rounded, sutural angles not pointed. Males with biseriate adhesive setae on full length of mesotarsomeres 2 and 3. Apex of abdominal sternite VII straight, with two setae on each side in both sexes. Median lobe of aedeagus stout (AL/AW= 4.0), ventral margin slightly inflated near middle; apical lamella slightly thick, LW slightly greater than LL, apex rounded; in lateral view, apical lamella slightly bent upward. Endophallus with very wide flared basal expansion of primary sclerite; flagellum extending beyond middle of median lobe; apical sclerite widely V-shaped, well-defined, basal core distinct, small and strongly scaled; basal sheath coarsely scaled, apical sheath finely scaled, smaller than basal sheath; squamate sac divided, dorsal to squamate sheath; proximal sac large and dorsal-ventrally compressed, distal sac much smaller than proximal sac, closer to apex. Gonocoxite II of ovipositor nearly quadrate, length slightly less than basal width, apex strongly concave, inner apical angle pointed; with two ensiform setae on outer apical angle, two or three on inner apical angle.

Kirschenhofer 2004" [red label], "COLL.WRASE / BERLIN". Notes on types and synonyms. Bothynoptera tesari Jedlička : This species was originally described from a single specimen from Karenko. The female we examined in the collection of NMPC in accord with the original description is undoubtedly the holotype. Parena esakii Habu : Kirschenhofer (2006) firstly proposed it is a synonym of P. tesari. We agree with this treatment according to the original description and illustrations. Parena nantouensis Kirschenhofer : We did not examine the type of this species. However, from the description and illustrations in the original description (Kirschenhofer, 1996), this species is almost identical to P. tesari except for its size (slightly smaller) and interval 3 with only two setigerous pores. We examined one specimen of P. tesari from Taiwan with two setigerous pores (the middle one missing) on the right elytron. Thus, we believe that the holotype of P. nantouensis is just an aberrant individual but not representing a separate species. Parena kataevi Kirschenhofer : This species was described from Hubei, Shennongjia. We examined specimens from Hubei and many other localities in central China that are in accord with it. Their male genitalia are identical to that of P. tesari from Taiwan. Thus, we treat P. kataevi as a junior synonym of P. tesari. Non-type material examined.

P. tesari is different from other species of subgenus Bothynoptera (except for P. obscura) in having the elongate tempora, which are gradually narrowed behind eyes. In other species, the tempora are very short and abruptly narrowed behind the eyes with the length of tempora plus neck-constriction approximately one-third of the diameter of the eye. Description. Body length 8.8–11.0 mm. Dorsum reddish brown to piceous; in dark color specimens, legs, antennae, and mouthparts distinctly lighter than body. Tempora gradually narrowed behind eyes, tempora plus neck-constriction two-thirds as long as eyes; vertex often with a pair of additional short setae postermedial to the posterior supraorbital seta; mentum with a pair of short setae. Pronotum nearly quadrate, PW/PL = 1.20–1.32, much narrower than head in most specimens, PW/HW = 0.85–0.95; lateral explanations narrow; widest at anterior third, slightly rounded at anterior half, and then clearly sinuate before posterior angles in most specimens; posterior angles nearly rectangular, more or less pointed outward. Elytra wide, slightly dilated to apex, surface without microsculpture; striae not incised or shallowly incised, with fine puncture rows in striae; intervals flat or slightly convex, with fine and sparse punctures; interval 3 with three setigerous pores, only two in some specimens; apical truncation indistinct, evenly rounded, sutural angles indistinct. Males with uniseriate adhesive setae on apical half of mesotarsomere 2 and biseriate adhesive setae on nearly full length of mesotarsomere 3. Apex of abdominal sternite VII with three setae on each side in both sexes, four pairs present in a few specimens. Median lobe of aedeagus slender (AL/AW = 4.5–4.8), apical lamella laminar, LL subequal to LW, slightly narrowed to apex, apex rounded. Endophallus with relatively small primary sclerite, flared basal expansion straight, apical flagellum very short, ending at basal third of median lobe; apical sclerite small and well defined, basal core elongate; basal sheath well scaled, apical sheath composed of three heavily scaled regions; squamate sac not divided, large and elongated, near middle of median lobe, right to squamate sheath. Gonocoxite II of ovipositor nearly quadrate, length slightly greater than basal width, apex slightly concave, with three or four ensiform setae on outer angle, and two or three on inner angle. Distribution (Map 7, blue). China (Anhui, Zhejiang, Jiangxi, Hubei, Hunan, Sichuan, Guizhou, Yunnan, Taiwan), Vietnam. Geographical variation. This species ranges throughout southern China. Its external features vary slightly and geographically in the following aspects: (1) Coloration: Dorsum is gradually darker from north to south. In most parts of China, the dorsum is always reddish brown. In southern provinces such as Taiwan and Yunnan, the dorsum is often nearly piceous, but dark brown individuals occur there as well. (2) Elytra striae: For specimens from most localities of China, elytra striae are well incised and intervals slightly convex. However, for specimens from Yunnan and Vietnam (Fig. 32D), the elytra striae are so shallow that striae 7 and 8 are hardly visible in the apical half. (3) Vertex setae: For specimens from mainland China and Vietnam, there is a pair of additional setae on vertex, which are shorter than the primary posterior supraorbital setae and placed posteromedial to them. However, such additional setae are absent from all specimens examined from Taiwan. Based on the above external differences, P. tesari can be divided into three populations: Taiwan, S. Yunnan + N. Vietnam, and other localities of China. We do not think they should be treated as subspecies because their male genitalia are almost identical (Fig. 34)., Published as part of Shi, Hongliang & Liang, Hongbin, 2023, Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina), pp. 1-144 in Zootaxa 5286 (1) on pages 58-62, DOI: 10.11646/zootaxa.5286.1.1, http://zenodo.org/record/7958937, {"references":["Jedlicka, A.

[43] Parena (Parena) ruficornis sp. nov. Habitus: Fig. 76F. Gonocoxites of ovipositor: Fig. 11W. Type locality. the Central African Republic, Lobaye province, La Maboke. Type material. Holotype (MNHN, Fig. 76F): female, body length= 9.2 mm, board mounted, "LAMABOKE / 2.v. 19 67 ", "MUSEUM PARIS / CENTRAFRIQUE / P.

Dorsum reddish brown, elytra largely black, suture and apex reddish brown; antennae uniformly reddish brown; tarsi yellow; elytra without microsculpture; elytral apices evidently truncate, outer apical angles well rounded, sutural angles slightly pointed, forming small denticles; gonocoxite II of ovipositor nearly quadrate, apex shallowly emarginate, with very long ensiform setae. Comparisons. This new species is very similar to other two African species, P. plagiata and P. africana, in elytra pattern (elytra largely dark with narrow red apices). However, the new species is quite different from them in: (1) elytra without microsculpture (with shallow isodiametric microsculpture in the other two species); (2) elytral apices distinctly truncate, apical margin straight near suture, and sutural angles slightly denticulate (Fig. 5B) (apical margin evenly rounded, sutural angles not pointed in the latter two species, Fig. 5A); and (3) antennomere 1 with the ventroapical seta only slightly shorter than the dorsoapical seta (Fig. 1D) (the ventroapical seta less than half length of the dorsoapical seta in the other two species, Fig. 1C). These three characters are considered to be important and support placing these three species in different species groups. (see discussions for P. scutata species group). The new species is sympatric with P. africana in the Central African Republic. In addition to the differences mentioned above, these two species are also different in having (1) first elytral interval completely reddish brown in P. ruficornis sp. n., but largely black in P. africana; (2) pronotum with lateral margins hardly sinuate before posterior angles in P. ruficornis sp. n., but more evidently sinuate in P. africana; and (3) in P. ruficornis sp. n., gonocoxite II of ovipositor nearly quadrate with very long ensiform setae (much longer than half of the basal width), but in P. africana, gonocoxite II of ovipositor nearly subulate (strongly pointed near inner angle) with relatively short ensiform setae (less than half of the basal width). Despite the different elytra pattern, P. ruficornis sp. n. is considered to be close to P. scutata and P. valeriae based on similarities in the shape of the elytral apices, elytra microsculpture, and setae on antennomere 1. The new species is different from P. scutata in: (1) P. scutata has seven apical antennomeres nearly black and basal ones reddish brown, but in the new species the antennae are entirely reddish brown; (2) in P. scutata, the elytral disc has a large red central patch which occupies the inner four or five intervals, but in the new species the elytra have no such red patch, instead just a narrow red stripe occupying the full length of interval 1; (3) in P. ruficornis sp. n., the elytral apices are more distinctly truncate and the sutural angles are more strongly pointed. The new species differs from P. valeriae in having slightly shallower elytra striae, smaller elytral sutural denticles, and a quite different elytra pattern. The above differences, especially for the color of antennomeres and shape of the elytral apices, are consistently useful for distinguishing different species in other groups of the genus. Therefore, we are confident that the new species is different from all related species, although the males of P. scutata and P. ruficornis sp. n. are both unknown at present. Description. Body length 9.2–9.7 mm, median-sized for the genus, subconvex. Color. Dorsum reddish brown; elytra disc largely black, the apical eighth, entire length of first interval, lateral margins, and basal area near scutellum reddish brown; scutellum reddish brown; antennae entirely reddish brown; venter reddish brown; all legs uniformly reddish brown. Head with sparse fine punctures on vertex; frons with shallow V-shaped depression; eyes large and strongly prominent; tempora very short, abruptly narrowed behind eyes, length of tempora plus neck-constriction approximately one-third of diameter of eye; postgenae without suborbital setae. Antennae extended beyond pronotal base by length of one antennomere; antennomere 1 with two apical setae close to each other, the ventral one slightly shorter than the dorsal one, longer than antennomere 2. Labrum quadrate, apex weakly convex; mandibles short and wide; mentum with a pair of long median setae, lateral lobes short and wide, inner margins strongly oblique, outer margins completely rounded, epilobes wide. Pronotum nearly quadrate, PW/PL = 1.43–1.47, slightly wider than head, PW/HW = 1.02–1.06, widest at anterior fourth, lateral explanations slightly wide; lateral margins rounded at anterior half and then gradually narrowed to base, slightly sinuate before posterior angles; posterior angles rounded obtuse; anterior margin nearly straight at middle; posterior margin weakly oblique at sides; disc convex, with fine punctures, without transverse wrinkles. Elytra weakly convex, slightly dilated to apex, surface without microsculpture. Striae very shallowly incised, with rows of fine punctures; intervals faintly convex, with very sparse fine punctures. Discal depressions shallow and large, nearly triangular, occupying intervals 3 to 6, greatest length near to one-third of elytra length; lateral weakly depressed near anterior third. Elytral basal pore present on base of stria 1; interval 3 usually with three discal setigerous pores: first one slightly behind level of scutellar apex, adjacent to stria 3; second one slightly before middle, adjacent to stria 3 or isolated; third one on apical eighth, adjacent to stria 2; on left elytron of one paratype, an additional pore present between the second and third pores; interval 9 with 24–26 umbilicular pores. Apical truncation evident, outer apical angles well rounded, apical margin gradually straighten to sutural angles, sutural angles slightly pointed, forming small denticles. Venter. Apex of abdominal sternite VII straight, with two setae on each side in females. Female genitalia. Gonocoxite II of ovipositor nearly quadrate, length subequal to basal width, apex shallowly emarginate, inner apical angle not pointed; apical margin with six to eight long ensiform setae, all longer than half of basal width, two or three of them grouped on inner and outer apical angles respectively, the remainder arranged near middle of apical margin. Distribution (Map 13, magenta). Only known form the Lobaye Province, the Central African Republic. Etymology. The scientific name is derived from two Latin roots: " ruf- " meaning red and " corn -" referring to the antennae. It refers to the uniformly reddish brown antennae, which distinguish the new species from related species., Published as part of Shi, Hongliang & Liang, Hongbin, 2023, Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina), pp. 1-144 in Zootaxa 5286 (1) on pages 132-133, DOI: 10.11646/zootaxa.5286.1.1, http://zenodo.org/record/7958937

9. Parena bicolor species group This species group contains three species, distributed through nearly all of the Oriental Realm and part of the Australian Realm. The two metallic species are very close to each other and are allopatric in geographical distribution. The third species is widely distributed and highly varied in elytra color pattern. Despite the different appearances, similarity in characters of the endophallic copulatory piece suggest a close relationship of these three species. Members of this species group differ from all other Oriental-Australian species in two aspects: (1) postgenae with a pair of suborbital setae; and (2) primary sclerite of endophallus linear, without a distinctly flared basal expansion (Figs 51, 52, 54). This group is most similar to the P. stigmatica group from Africa, but in the latter the basal expansion of the primary sclerite of endophallus is distinctly flared., Published as part of Shi, Hongliang & Liang, Hongbin, 2023, Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina), pp. 1-144 in Zootaxa 5286 (1) on page 85, DOI: 10.11646/zootaxa.5286.1.1, http://zenodo.org/record/7958937

P. obenbergeri is very similar to P. laesipennis. It differs from the latter species only in having the elytral apical truncation more distinct and the outer apical angles sharper. However, with the male genitalia of P. obenbergeri having the apical lamella distinctly narrower than in P. laesipennis and the wide distributional gap between them, we treat it as a distinct species. Description. Body length 9.9 mm. Dorsum reddish brown; basal three antennomeres, and basal half of antennomere 4 reddish brown, rest parts of antennae nearly black; venter brown. Pronotum strongly transverse, PW/PL = 1.60, slightly wider than head including eyes, PW/HW = 1.08; lateral explanations very wide. Elytra without microsculpture; striae not incised, replaced by lines of fine punctures; intervals completely flat, very finely and sparsely punctate; disc depressed near middle of intervals 3 to 6, depressions subtriangular; apical truncation distinct, straight, outer apical angles well angulate, forming distinct obtuse angles; sutural angles pointed, forming short spines. Median lobe of aedeagus gradually narrowed to apex, ventral margin almost straight; apical lamella slightly bent to dorsum, length 1.75 folds as its basal width, apex rounded. Endophallus very densely scaled on basal sheath, base of apical sheath ovate in dorsal view; squamate sac indistinctly divided, on basal fifth of median lobe, right to squamate sheath.
