A male specimen labeled ���Tschang Tang, Tibet ��� From ZFMK (1 6, Tibet, Tschang-Tang, Dsagar- Berge, 4500 m, Juli, ex coll. Wehrli, 17/55.) has clearly different antennae and male genitalia. It should be treated as another new species of Aquilargilla (D. St��ning, pers. comm.). However, since the single specimen is in bad condition and the locality is dubious, more specimens need to be collected and studied to enable it to be described in future. Etymology. The species is named on the basis of Latin word basifixus, which relates to the processes arising from the base of the tegumen., Published as part of Cui, Le, Xue, Dayong & Jiang, Nan, 2018, Aquilargilla gen. nov., a new genus of Sterrhinae from China with description of two new species (Lepidoptera, Geometridae), pp. 431-437 in Zootaxa 4514 (3) on pages 433-436, DOI: 10.11646/zootaxa.4514.3.8, http://zenodo.org/record/2608156

Aquilargilla gen. nov. Type species. Aquilargilla ceratophora sp. nov. Gender feminine. Description. Head. Antennae sub-quadripectinate (longly bipectinate with short additional branches from base, ventral side of each segment) in male; filiform in female. Forewing length: ♂ ♀ 14���16 mm. Frons slightly protruding. Vertex usually pure white. Labial palpi slightly extending beyond frons. Thorax. Male hind tibia without spurs, not dilated and without hair-pencil in male, two pairs of spurs present in female. Frenulum well developed in both sexes. Forewing with apex pointed, hind wing with apex rounded. Postmedial line wavy. Discal spots on fore- and hind wings usually black and faint. Venation. Forewing with one or two areoles within species; veins R 2���4 always from apical angle of areole, veins R 1 and R 5 distally or directly from apex; veins R 5 and R 2���4 sometimes shortly stalked. Vein M 2 closer to M 1; Veins M 3 and CuA 1 unstalked. Hind wing with veins Rs and M 1 usually short-stalked, sometimes separate and from apical of discal cell; M 3 and CuA 1 separated. Abdomen. Male 8 th tergite with posterior margin concave and forming a pair of narrow spine-like lateral processes. Male 8 th sternite with anterior margin strongly concave, cerata horn-like, arising from ventral side of mappa, mappa rounded. Male genitalia. Uncus and gnathos absent. Socii composed of a pair of small processes. Tegumen with one or two pairs of processes on inner margin. Valvula and sacculus separate. Juxta quadrate with a pair of lateral lobes. Coremata present (easily lost during preparation). Saccus concave medially. Aedeagus strongly curved; vesica with a small patch of tiny spines. Female genitalia. Papillae anales rounded. Lamella antevaginalis well developed; lamella postvaginalis not developed. Ostium sclerotized. Ductus bursae narrow. Corpus bursae large and elongate; signum with a patch of small and scobinate sclerites, pointing away from longitudinal axis. Diagnosis. The male antennae in Aquilargilla is sub-quadripectinate and uncommon in the tribe Scopulini, which is similar to Ideae serpentata (H��fnagel, 1767) of the tribe Sterrhini, but the rami in Aquilargilla are much longer. The posterior margin of the male 8 th tergite in Aquilargilla is concave and forms a pair of lateral spines; this character is also present in the type species of the genus Dithalama (D. cosmospila Meyrick, 1888). The shape of the male 8 th sternite in Aquilargilla is unique in the Scopulini, as the anterior margin is strongly concave, and the cerata are present, arising from the ventral side of the mappa. In the male genitalia, the processes on the inner side of the tegumen in Aquilargilla are atypical but not unique among the Scopulini, as a similar structure is found in Somatina mendicaria (Leech, 1897) and Dithalama. The juxta in Aquilargilla is unique in the Scopulini, as it is quadrate with a pair of lateral lobes. Etymology. The generic name is derived from the Latin dark (aquilus-) and clay (argilla), corresponding to the dark colour of the wings of the type species. The name is to be regarded as feminine. Remarks. The DNA work was attempted but failed in our study., Published as part of Cui, Le, Xue, Dayong & Jiang, Nan, 2018, Aquilargilla gen. nov., a new genus of Sterrhinae from China with description of two new species (Lepidoptera, Geometridae), pp. 431-437 in Zootaxa 4514 (3) on page 432, DOI: 10.11646/zootaxa.4514.3.8, http://zenodo.org/record/2608156, {"references":["Hufnagel, J.

Syntypes, India: Kangra (NHM). Problepsis attenuata Warren, 1909, Novit. zool., 16: 126. Holotype ♂, India (south): Merkara (NHM). Diagnosis. The species is similar to P. paredra Prout, 1917 in the following characters: the ocellus of the forewing is inverted pyriform, the posterior part is narrower than the anterior part, the outer margin is protruding outwards centrally and concaved between M veins; the ocellus of the hind wing is similar to that of the forewing, but it is pyriform; the internal margin of the tegumen of the male genitalia is strongly dentate; the aedeagus has a patch of small teeth at apex, the vesica has sclerotized bands; the central process of the male eighth sternite is very short and not dilated at apex; the lamella postvaginalis of the female genitalia is merged with the ductus bursae. However, the species can be distinguished from P. paredra by the following characters: the pectinations of the male are longer than twice the diameter of the shaft, while those are slightly longer than the diameter of the shaft in P. paredra; the hind tarsus of the male is about one-half the length of the tibia, while in P. paredra, it is about one-third or shorter than one-third the length of the tibia. In the male genitalia, the fused socii is shorter than P. paredra, the valvula is narrower than the sacculus, but it is about equal in width with the sacculus in P. paredra. In the female genitalia, the ductus bursae is much narrower, the length of the ductus bursae are more than twice of its width, while in P. paredra, the length of ductus bursae is less than twice of its width in female genitalia.

China (Heilongjiang, Jilin, Beijing), Southeast Russia, North Korea. Remarks. In our study, we found the species and P. discophora only show some differences on the shape of ocellus. Besides, we also found one male specimen from Beijing (figs 24, 49, 70) shows a transition between the two species: the ocellus of the forewing is fused to the posterior small marking, smooth on the inner margin, and forms a small protrusion on the outer margin, not reaching the postmedial line; the ocellus of the hind wing is similar to that of P. phoebearia. Therefore we suspect P. phoebearia and P. discophora maybe the same species., Published as part of Xue, Dayong, Cui, Le & Jiang, Nan, 2018, A review of Problepsis Lederer, 1853 (Lepidoptera: Geometridae) from China, with description of two new species, pp. 101-127 in Zootaxa 4392 (1) on page 123, DOI: 10.11646/zootaxa.4392.1.5, http://zenodo.org/record/1195157, {"references":["Erschov, A.

Distribution. China (Gansu, Hubei, Hunan, Fujian, Taiwan, Guangdong, Hainan, Yunnan, Tibet), India (Sikkim), Myanmar. Remarks. Problepsis conjunctiva subjunctiva was originally described by Prout (1917). He mentioned the subspecies can be distinguished from the nominate subspecies by the smaller size, the narrower band between the ocellus of the fore- and hind wing, and the less darkly marked underside of the wings. In our study, we found one male specimen from Hainan (Lingshui, Diaoluo Shan, figs 17, 42, 63) well agree with the description of Prout (1917). In addition, we also found one female from Hainan (Tongshen, fig. 16), together with the specimens from Yunnan and Tibet (figs 15, 43, 64), well agree with the description of the nominate subspecies. The specimens from Hunan, Fujian and Guangdong shows transitions between the two subspecies in different extent. The genitalia of the above specimens shows no differences. Therefore, we consider the varied character of subjunctiva as intraspecific individual variations, and treat P. conjunctiva subjunctiva Prout, 1917 as a junior synonym of Problepsis conjunctiva Warren, 1893. We also found the venation also varies in the species: the forewing of some specimens from Gansu, Hubei, Yunnan and Tibet (about one-third of all examined material) has no areole and R1 is free from R2-5, in contrast, the forewing of the remaining specimens has one areole. However, these specimens do not show any differences on the external charcters and the genitalia., Published as part of Xue, Dayong, Cui, Le & Jiang, Nan, 2018, A review of Problepsis Lederer, 1853 (Lepidoptera: Geometridae) from China, with description of two new species, pp. 101-127 in Zootaxa 4392 (1) on pages 116-118, DOI: 10.11646/zootaxa.4392.1.5, http://zenodo.org/record/1195157, {"references":["Warren, W.

The size of the species is often large (the forewing length is 24–30 mm in male, and 26–31 mm in female); the male antenna is dentate; the vertex is white; the hind tarsus of the male is about one-half the length of the tibia; the postmedial line of the forewing is invisible near the costa; the ocellus of the forewing is large and rounded, consists of a black inner ring which is opened at anterior part, an incomplete silvery ring inside the black ring, two black patches on both sides of CuA1, and strip-like white discal spot; the ocellus of the hind wing is oval and darker than that of the forewing, covered with silvery scales; the central part of postmedial line of the hind wing is very close to the ocellus. The male genitalia are similar to P. shirozui, but the fused socii are shorter; the basal lobe of the valvula is semicircular, while it is triangular in P. shirozui; a large patch of teeth are present at the central of the aedeagus, while they are absent in P. shirozui; the manica has no spines at the apex, and two sclerotized bands arising from the dorsal side, one of them is covered with small teeth on terminal half; the vesica has a narrow and long sclerotized band, which forms a spine-like cornutus apically; the eighth sternite of the male has two long lateral processes and one short digitiform central process. The female genitalia are distinctive in the following characters: the lamella postvaginalis and the lamella antevaginalis are fused to the stout and strongly sclerotized dctus bursae, and a pair of curved digitiform membranous process are present on the ventral surface of the posterior margin; the corpus bursae is slightly sclerotized on right side of the posterior part; the signum is situated on the dorsal surface of the left side of corpus bursae.

Remarks. Prout (1935) described a new form of this species from Yunnan, P. superans f. summa, based on the larger size and the lager ocellus. Parsons et al. (1999) listed the form as a subspecies of P. superans. After examination of a long series of material, we found the size of the adults and the size of the ocellus are varied at the same locality, e.g. Hubei, figs 29, 30. In addition, there is no genital difference among the specimens from different localites of China. Therefore, we still consider summa as a variant form of P. superans., Published as part of Xue, Dayong, Cui, Le & Jiang, Nan, 2018, A review of Problepsis Lederer, 1853 (Lepidoptera: Geometridae) from China, with description of two new species, pp. 101-127 in Zootaxa 4392 (1) on pages 123-126, DOI: 10.11646/zootaxa.4392.1.5, http://zenodo.org/record/1195157, {"references":["Butler, A.

Problepsis discophora discophora Fixsen, 1887 Figs 21, 22, 46, 67, 87, 104 Diagnosis. Similar to P. shirozui Inoue, 1986 in the following external characters: the antennae of the male is dentate; the vertex is white; the hind tarsus of the male is about one-third to one-half the length of the tibia; the ocellus of the forewing is rounded, consists of complete greyish silvery inner ring, black patches between M veins and on both sides of CuA1, black scales which are covered around the slivery ring, and strip-like white discal spot; the ocellus of the hind wing is simiar to that of the forewing, but is oval and the silivery ring is opened at anterior part. But the species can be distinguished by the following characters: the postmedial line of the forewing is thickened on the costa, while in P. shirozui, it is narrow and weak; the grey band on the forewing costa of the underside is lighter than that of upperside, while it is darker and more distinct than that of upperside in P. shirozui; the ocellus of both wings of the underside are much lighter than those of P. shirozui; in the male genitalia, the fused socii have a digitiform process at the base of the ventral surface, while the process is absent in P. shirozui; the valvula is angle-like at the central part, while it is smoothly curved in P. shirozui; two sclerotized band are present at the the manica of the aedeagus, but they are absent in in P. shirozui.

Problepsis discophora kardakoffi Prout, 1938 Figs 23, 47, 68, 88, 105 Problepsis discophora kardakoffi Prout, 1938, in Seitz, Macrolepid. World, 4 (Suppl.): 222. Holotype ♂, Russia: S Ussuri, Vladivostok district,?Okeanskaja (NHM). Diagnosis. The subspecies differs from the nominate subspecies externally by the following characters: the submarginal spots of both wings are larger and darker, inner ones are fused or touch to outer ones partly, and outer ones are fused to the terminal lines except on the apical area of the forewing, while the submarginal spots of the nominate subspecies are lighter, inner ones are separate from outer ones; the fringes are mostly dark grey to blackish grey, but they are white mixed with grey in the nominate subspecies. The subspecies is almost identical to P. phoebearia Erschov, 1870 in the dentate male antenna, the white vertex and the length of the hind tarsus of the male and the genitalia, and only can be distinguished by the smaller ocellus of each wings. P. phoebearia has larger ocellus, the one of the forewing is fused to the posterior small marking, forms one to three teeth on the inner margin, and protrudes beyond or touch the postmedial line on the outer margin; the one of the hind wing is partly or mostly covered the postmedial line.

Problepsiodes argentisquama Warren, 1899b, Novit. zool. 6: 337. Holotype ♂, Peninsular Malaysia: Penang (NHM). Diagnosis. The species is easily recognized by the following characters: the pectinations of the male are about equal length of the diameter of the shaft, and the antennae of the female is dentate; the vertex is black; the hind tarsus of the male is about one-half the length of the tibia; the ocellus of the forewing is inverted pyriform, tapered at posterior part, smooth on the outer margin; the ocellus of the hind wing is oval; the underside of the wings has heavy dark greyish brown suffusions from the base to the submarginal lines except the area near the anal margin of the forewing and the area near the costa of the hind wing. The male genitalia are similar to those of P. transvehens (Prout, 1918), but the fused socii and the juxta are longer; the aedeagus is narrower, curved at the apex and near the central part, and has a tiny spine-like subapical process on lateral side, while in P. transvehens, it is not curved, and forms a long lobe terminally, and the subapical process is larger and triangular; the vesica has a short sclerotized band, while it has a small irregular shaped lobe in P. transvehens; the eighth sternite of the male is longer, and narrower at posterior part. The female genitalia are unique in the following characters: the lamella postvaginalis is weakly sclerotized with a pair of small digitiform processes on left side; the ductus bursae is narrow and long, weakly sclerotized on posterior half, membranous with a narrow sclerotized band on anterior half.

Type species: Problepsis conjunctiva Warren, 1893. India. Generic characters: Head: Male antennae bipectinate or dentate, with fascicles of cilia (often bipectinate in African species); female antennae often filiform, sometimes dentate, ciliated. Frons not protruding. Labial palpus extending beyond frons distally. Thorax. Ventral surface of thorax and fore femora hairy. Male hind tibia dilated, with hair-pencil, without spurs; tarsus abbreviated; female hind tibia normal, with two pairs of spurs. Venation: Forewing often with one single areole, but variable in P. conjunctiva Warren, 1893, (see its remarks). R1 arising from or before apex of areole; R5 usually long stalked with R2-4. Hind wing with Rs and M1 separate, M3 and CuA1 separate. Forewing with apex almost quadrate, outer margin arched; hind wing with apex rounded, outer margin slightly wavy. Wings ground colour white or greyish white or light ochre-brown or light grey. Each wing usually with a ocellus at end of cell, sometimes invisible on both wings (e.g. P. rorida Prout, 1932 and P. ochripicta Warren, 1901), or indistinct on hind wing (e.g. P. aegretta Felder & Rogenhofer, 1875 and P. flavistigma Swinhoe, 1904); ocellus usually containing silvery scales, projecting from surface, sometimes containing dark patches and white stripe-like discal spot inside, submarginal line often composed of two rows of spots.

Socii fused at apex, ventral of tuba analis, setose, sometimes with lateral or central lobes. Valvula and sacculus separate, symmetrical, long, tapering towards apex. Juxta forming an inverted triangular or tongue-like lobe, anterior margin concaved centrally, fused to sacculus, sometimes free. Saccus broad. Aedeagus strongly sclerotized, with one or several teeth at apex, coecum penis dilated; vesica often with partly sclerotized and crinkled, sometimes with cornuti. Male eighth sternite elongated and anterior margin bifurcate, often with one process centrally, forming a head-shaped posterior dilation. Female genitalia: Papillae anales stout and short. Lamella postvaginalis often well developed; lamella antevaginalis often absent, sometimes weakly developed. Ductus bursae often sclerotized. Corpus bursae large, spherical or oval, membranous; signum sometimes absent, often composed of an oval patch of small spines, arranged in longitudinal rows, medial spines often fused to a sclerite along longitudinal axis. Diagnosis. The genus is unique in the ocellus of the wings and the fused socii of the male genitalia. Biology. The host-plant records are mainly from the Oleaceae (Singh 1957; Sugi 1987; Holloway 1997). The habitat preferences of some Problepsis species are provided by Holloway (1997) and Stadie & Stadie (2016). The larvae are long and slender, tapered anteriorly and often without any pattern (Stadie & Stadie 2016). They rest on straight position, and are able to produce a silk thread if they are disturbed (Hausmann 2004; Stadie & Stadie 2016). Distribution. Palearctic, Oriental, Australian, and Afrotropical regions. Remarks. Considering the present study is a review of Chinese species of Problepsis, the above generic characters are mainly summarized from Chinese species, and also from the studies of Prout (1912 ���1916, 1934��� 1939, 1920���1941, 1929���1938), Holloway (1997), Hausmann (2004), Sihvonen (2005) and Stadie & Stadie (2016).

Problepsis transvehens (Prout, 1918) comb. nov. Figs 14, 41, 62, 83, 100 Somatina transvehens Prout, 1918, Novit. zool., 25: 81. Holotype ♂, China: Hainan, Manchyo (NHM). Diagnosis. The external characters of the species are characterized by: the male pectinations are short than the diameter of the shaft; the vertex is black, and diffused with white on the posterior margin; the hind tarsus of the male is about two-fifths length of the tibia; the forewing R5 is shortly stalked with R2-4 or separate; the ocellus of fore- and hind wings are incomplete, the former is narrow band-like, covered by pale yellowish brown mixed with silvery scales, the latter is indistinct, cosists of two silvery lines and sparse yellowish brown scales centrally. The diagnosis of the male genitalia could be seen under P. delphiaria auriculifera. The female genitalia are unique in the small semicircular lamella postvaginalis and the short partly sclerotized ductus bursae. Material examined.

Prout (1938) mentioned this species shows the venational transitions between Somatina Guen��e, 1858 and Problepsis. Later, Sihvonen (2005) mentinoned the species should probably be combined with Problepsis, as it has weakly developed ocellus and slivery scales. In our study, we found this species well agrees with Problepsis in the wing patterns and the genitalia, especially the slivery (opalescent) scales on the wings. Hausmann (2004) mentioned the structure and arrangement of the opalescent scales are unique in Geometridae. Therefore we transfer this species to Problepsis., Published as part of Xue, Dayong, Cui, Le & Jiang, Nan, 2018, A review of Problepsis Lederer, 1853 (Lepidoptera: Geometridae) from China, with description of two new species, pp. 101-127 in Zootaxa 4392 (1) on pages 115-116, DOI: 10.11646/zootaxa.4392.1.5, http://zenodo.org/record/1195157, {"references":["Prout, L.

Problepsis crassinotata Prout, 1917 Figs 18, 44, 65, 85, 102 Problepsis crassinotata Prout, 1917, Novit. zool., 24: 310. Holotype ♂, India: Khasi Hills (NHM). Diagnosis. The species is characterized by the following characters: the male antenna is dentate; the vertex is black; the hind tarsus of the male is about two-fifths the length of the tibia; the ocellus of the forewing is rounded, consists of an incomplete black inner ring and covered by greyish silvery scales; the ocellus of the hind wing is digitiform and narrow at anterior half, broad and rounded at posterior half, darker than that of the forewing, and contains a dark greyish silvery inner ring at posterior half. The male genitalia of the species are similar to P. diazoma Prout, 1938, but the base of the valvula is much narrower, without a small digitiform process inside; the apical spine of the aedeagus and the coecum penis is larger; the vesica has two narrow, long, curved sclerotized band and one tiny lobe, while the later lobe is replaced by two small lobes and one large spinous lobe in P. diazoma;the central process of the eighth sternite of the male is much shorter. The female genitalia of the species are also very close to P. diazoma in the short and dilated ductus bursae and the signum, but the two digitiform membranous processes of the posterior margin of the lamella postvaginalis are smaller.

A reliable external distinguishing character of S. histrionaria compared to S. sanguinaria, except those mentioned already under sanguinaria, is the straight medial line of hindwing, composed of short costal and anal streaks, with the large discal spot in the middle. S. sanguinaria has a round anal spot, a distinctly smaller discal spot with less white in the centre, and no costal spot or streak. Further comparisons on external characters and genitalia see under S. sanguinaria. S. ornata (Bastelberger), has for long been treated as a subspecies of S. histrionaria, but is raised to species-rank again.

Moreover, the postmedial line is always continuous and less distinctly curved outwards at the centre of the forewing than in S. histrionaria. In most specimens of S. ornata also a continuous medial line is present, running distally along the discal spot. In S. histrionaria a short streak near anal margin of forewing indicates the position of the medial line only. In the hindwing, the medial line is continuous and curved in S. ornata, almost straight and interrupted in S. histrionaria. Besides a dark, strongly suffused, crimson-brown form (Fig. 6) also a lighter form with yellowish bands between medial and postmedial lines and also at basal half of the wings occurs (Fig. 7); both were collected at the same locality: C. Taiwan, Arrizan, Khagi District, at elevation of 7000���10000 ft (Bastelberger 1909), the light form also at slightly lower elevation (specimens in coll. ZFMK). Type-specimens photographed in the collection of SDEI agree with the light form. S. ornata is similar to S. hyriaria and S. elasmlatus, sharing with them the yellowish or red-brown coloration and similar transverse bands. However, S. ornata has one areole in the forewing venation, but there are two in S. hyriaria and S. elasmlatus. The male genitalia of S. histrionaria and S. ornata differ in the shape of the uncus (much narrower in S. ornata, with different apical sclerotization) and in the saccular, ventral process which is acute in S. histrionaria and rounded at tip in S. ornata. The aedeagus has a rather narrow vesica, with a compact cornutus, rounded on proximal side, and an elongate sclerotized band in S. ornata, in S. histrionaria the aedeagus is longer and broader, the vesica is decorated with a weakly sclerotized patch only. The female genitalia are distinct from those of S. histrionaria particularly in the structure of the lamella postvaginalis. The imbricate process of S. histrionaria is absent, instead a longitudinal, sclerotized bulge is present. It is continued posteriorly with a furrowed, granulose, transparent plate. Other structures of the genitalia are similar and only gradually differing. Material examined. CHINA: Taiwan (ZFMK): 2 6, " Formosa "; 1 6 1♀, " Ile Formose, Moltrecht, 1908", ex coll. E.

Synegiodes diffusifascia Swinhoe, 1892 Figs 8, 20, 30 Synegiodes diffusifascia Swinhoe, 1892, Trans. ent. Soc. Lond. 1892 (1): 11, pl. 1, fig. 9. Syntype (s) ��, India: Khasi Hills (BMNH). Diagnosis. The species S. diffusifascia, S. expansus and S. obliquifascia resemble each other externally. General coloration and transverse lines and bands on wing surface are so similar that it is impossible to identify these three species only based on wing markings. However, S. diffusifascia and S. expansus can be separated by having one areole in the forewing venation, while there are two in S. obliquifascia. In the male genitalia, S. diffusifascia can be differentiated from the other two species by the ovally extended apex of the uncus and the rim-like process on the anellus. The female is unknown to us. More detailed comparisons with the other two species see under S. expansus. Material examined. INDIA (ZFMK): 1♂, paratype, ex coll. BMNH by exchange, "Khasis, Nat. Coll.", gen. prep. No. 2322-DS. Distribution. India, Vietnam (Tonkin: Prout (1938: 152), Malaysia (Pahang: Prout (1938: 152). Records from Vietnam and Peninsular Malaysia may refer to S. expansus sp. nov. or the undescribed species from Borneo. Remarks. Holloway (1997) recorded diffusifascia from Borneo, supplying also a photo of the male genitalia. The dissection of a topotypical paratype of S. diffusifascia revealed that particularly ���socii��� and uncus are different from the illustration provided by Holloway (1997: genitalia fig. 7). In the male genitalia of the paratype, the tip of the uncus is ovally enlarged, and the socii are inflated dorsally at base, while in fig. 7, the uncus is apically not enlarged and the socii are swollen ventrally at middle, the bases narrower. So the species found in Borneo very probably may be another, undescribed one (provided that the paratype we were able to study is conspecific with the holoype of diffusifascia)., Published as part of Cui, Le, Jiang, Nan, St��ning, Dieter & Han, Hongxiang, 2018, A review of Synegiodes Swinhoe, 1892 (Lepidoptera: Geometridae), with description of two new species, pp. 259-274 in Zootaxa 4387 (2) on page 266, DOI: 10.11646/zootaxa.4387.2.2, http://zenodo.org/record/1187402, {"references":["Swinhoe, C.

Synegiodes Swinhoe, 1892 Synegiodes Swinhoe, 1892, Trans. ent. Soc. Lond. 1892: 11. Type species: Anisodes sanguinaria Moore, 1868. (here fixed under Article 70.3 of the Code, misidentified as Anisodes diffusaria Moore, 1868 in the original designation by Swinhoe (1892). Synegioides Swinhoe, 1893, Ann. Mag. nat. Hist. (6) 12: 150. An incorrect subsequent spelling. Generic characters. Moths of moderate size, wingspan roughly between 25 and 35 mm. Species of Synegiodes are superficially similar to members of the ennomine genera Synegia Guene��, Yashmakia Warren or some species of Parasynegia Warren externally, but are distinguished by the discal spot which is white-centred and ringed black on outer edge in Synegiodes [but some Parasynegia also have discal spots with white centre] (besides other evident differences between the subfamilies) (Holloway 1997). Wings broad, apex of forewing moderately pointed, termen waved between the vein ends, moderately projecting at end of vein M3 (more strongly so in the hindwing). Pattern consisting of transverse, more or less inclined, sometimes interrupted lines or bands of variable shape, antemedial line absent or weak in all species (if present, indicated by a few black dots on veins only). Coloration grey or brown, in some species pinkish or red on yellow or orange ground color. Discal spots distinct, consisting of a black circle with a white center, larger in the hindwing in all but one species. Head. Antennae bipectinate, with terminal 1/4���1/3 filiform in male, rami long and narrow, dorsally not scaled, with rows of long sensillae; filiform, very shortly setose (pubescent) in female. Frons broad (broader than compound eyes in frontal view), smooth-scaled (scales very small), roundly protruding, lateral margins steep (less expressed in females). Vertex with slightly larger, contrastingly colored, smooth scales, pure white and shining in almost all species. Chaetosemata present near margin of compound eyes, but consisting of a few setae only. Labial palpi rather short and porrect in males, curved upwards in females, third segment slightly (in males) or distinctly (in females) extending beyond frons. Proboscis well developed. Thorax. Patagia and tegulae covered with larger, lamellar scales of different colors, distal scales of tegulae elongate, only very few hair-like. Hind tibia long, with two pairs of spurs in both sexes, not dilated and without hair-pencil in male. Tarsal segments not modified in males. Posterior surface of metathorax, opposite to the tympanal opening, covered with a large, scaled, sometimes folded membrane in males (Fig. 45), rarely with a brush of elongate scales outside. Frenulum well developed in both sexes. Forewing with one elongate or two smaller areoles (i.e., in the latter case, the elongate areole is divided by the -still present- base of vein R2). Prout (1918) used this character to separate the genus into two species-groups. However, the venation of both wings is considerably variable, interspecific as well as intraspecific, especially in relation to the veins branching off from areole (but not in relation to the number of areoles). The common stalk of the veins R2���4 is always arising from the apical angle of the areole, but the veins R1 and R5 can arise proximally or distally or directly from the apical angle of the areole, or the origin of both may even be different in both wings in the same specimen. Veins M3 and CuA1 are not stalked. In the hindwing, the veins Rs and M1, and M3 and CuA1 are short-stalked or not stalked, sometimes stalked only in one of the two pairs. Pregenital abdomen. Tergites and sternites weakly sclerotized (tergites 1 and 2 and sternite 1+2 slightly stronger so), without modifications; tympanal organs without laciniae, ansa hammer-headed; sternite 3 without setal comb. Male genitalia. Uncus very broad at base, truncate or slightly bilobed at apex in a group of four species including the type-species; long and thin in the remaining five species. In the latter species-group, large ���socii��� (Holloway 1997) of variable shape arise from the posterior portion of the tegumen. Gnathos absent. Valva narrow at basal half, even narrower distally, costa well sclerotized until tip, the latter with strong, curved setae; sacculus with a small process, pointed or rounded at tip, arising more or less from the middle of the ventral margin of valves. Juxta elongate, often constricted centrally. Anellus sclerotized, ring like, sometimes with a process or a rim on posterior margin. Aedeagus narrow (e.g. Fig. 29), vesica narrow and simple or aedeagus larger and broader (e.g. Fig. 30), vesica voluminous and composed of several diverticula. Cornutus-like structures or sclerotized bands always present (absent in brunnearia). Male genitalia of S. brunnearia distinctly different in most characters (Fig. 25). Female genitalia. Apophyses anteriores roughly about 1/2 as long as apophyses posteriores, weak and narrow, moderately strong, or short and stout. Lamella postvaginalis not or only weakly sclerotized, triangular or appearing as an irregular, longitudinal plate. Two species (histrionaria, expansus) with more conspicuous sclerotization. Lamella antevaginalis a narrow, arched bridge between the antero-ventral angles of genital segment in most species. Ostium sometimes surrounded by a wide ostial funnel, the latter weakly sclerotized. Colliculum developed in all species, varying in size. Ductus bursae abruptly widening near colliculum, with diverticula of variable size distally, then moderately wide or as wide as corpus bursae, both often not separable from each other. Signum composed of a narrow, longitudinal sclerotized rib, set on a slightly sclerotized, flat plate of variable shape, anteriorly bent inwards and forming a triangular pouch in the bursa wall (all except hyriaria and elasmlatus in which the signum is shaped differently and the pouch is absent). Remarks. On the basis of essential differences of the male genitalia, members of Synegiodes, as it is currently defined, are divided into two species-groups, either of which may be monophyletic. The first group consists of four species, sanguinaria, punicearia, histrionaria and ornata stat. rev. All these species have very broad, stout, distally truncate or slightly bilobed, strongly sclerotized uncus, but lack teguminal processes (���socii���). We refer to this group as the ��� sanguinaria group���. The second group consists of five species, obliquifascia, diffusifascia, expansus sp. nov., hyriaria and elasmlatus sp. nov., in which the male genitalia are characterized by the presence of a narrow, elongate uncus and conspicuous processes diverging from the posterior part of the tegumen, stretching ventrally like gnathal arms in their natural position (���socii��� sensu Holloway 1997). We refer to this group as the ��� obliquifascia group���. These two groups also can be differentiated by the wing pattern: the species of the sanguinaria group are more or less tinged with pink, the medial line on the forewing is indistinct, and that on the hindwing is only represented by a short patch (except in ornata); the members of the obliquifascia group are not tinged with pink, and the brown medial line is distinct on both, fore- and hind wings. Such essential differences are usually not found among species of the same genus and the question turned up whether a new genus was necessary for the reception of the obliquifascia group. Prout (1918) turned the attention to the existence of one or two areoles in the forewing venation of different species, and later he separated the species of Synegiodes into two sections, based on this character (Prout 1938). One section includes sanguinaria, diffusifascia, histrionaria, ornata, punicearia and expansus sp. nov. which have one areole, and the other species, obliquifascia, hyriaria and elasmlatus sp. nov., have two areoles, i.e. the resulting subdivision is a different one, compared to the use of wing pattern and male genitalia for separation of the groups. Considering the similarity of other parts of the male genitalia, such as valva, juxta, anellus, aedeagus, and those of the female genitalia across both species-groups, we believe that it is not justified to separate the species of Synegiodes into different genera.

Synegiodes expansus Cui, Jiang & Stüning sp. nov. Figs 9–10, 21, 31, 40 Description. Forewing length: 12–14 mm in male; 14–15 mm in female. Head. Frons mostly white, sometimes brown or deep brown basally; vertex pure white. Thorax. Patagia pale yellowish brown, tegulae brownish at base and pale brown in other areas; dorsum yellowish brown; same coloration found in the abdomen. Wing pattern. Wings pale yellowish brown, suffused with brown spots; transverse bands brown. Costa of forewing slightly curved, apex of forewing acute; termen faintly projecting on vein M3 and even more strongly so on hindwing, with a shallow incision between M1 and M3; tornus and apex of hindwing rounded; antemedial line indistinct, indicated by three black vein-spots; medial line oblique and rather broad, expending near costa, often with an external tooth on origin of M3 from cell; postmedial line slightly curved outwards, consisting of black vein-spots, accompanied distally by a broad, dark brown band which can be expended to outer margin, the posterior part reaching tornus, but leaving smaller or larger patches of the yellowish-brown ground color included. Sometimes small, rather vague black spots are present between veins M2 and M3 and CuA2 and A, close to the postmedial line; discal spot on forewing very small, white, ringed black. Medial line on hindwing almost straight, homogenous in thickness; postmedial line as in forewing, but more strongly curved, rarely expanded to outer margin, more often leaving a band of the yellowish-brown ground-color along margin, the latter incurved between and dentate on vein-ends. Discal spot on hindwing white centred and black on outer edge, more often inside the medial line than near its distal edge. Fringe yellowish brown on both wings, black on vein ends. Underside. Ground color lighter (rather yellowish-white), with less suffusion than on upperside, transverse lines distinct. Male genitalia (Figs 21, 31). Uncus long and stick-like. “Socii” developed, apically extended, forming a plate. Gnathos not developed. Valva broad at base, terminal part gradually becoming narrower, with rounded, setose apex; costa straight at basal half; sacculus small, with a pointed distal process. Juxta long, constricted in the middle and expanded sheet-like posteriorly. Anellus sclerotized, with posterior part broadened. Aedeagus large, vesica inflated basally, with two diverticula, the elongate cornutus situated more distally. Female genitalia (Fig. 40). Papillae anales distally rounded. Apophyses anteriores short and stout, about one-third of the narrow apophyses posteriores in length. Lamella postvaginalis consisting of two sclerotized, longitudinal, terminally curved ridges, with a pair of small, round processes distally. Lamella antevaginalis formed as a U-shaped, laterally sclerotized ostial funnel. Colliculum well developed. Corpus bursae and ductus bursae proximally and distally almost of the same width, not separable, diverticulum short; signum with a longitudinal sclerite inside a slightly sclerotized plate, a pouch present distally. Diagnosis. S. expansus is close to S. diffusifascia and S. obliquifascia externally, especially the transverse lines are similar, however, the number of the areoles is one in S. expansus and S. diffusifascia, but two in S. obliquifascia. The postmedial band on the hindwing is much wider than in S. obliquifascia, but all transverse lines are more strongly inclined in the latter. In the male genitalia the apical parts of the “socii” are flattened and extended plate-like, and the anellus is broadened in S. expansus, while in S. obliquifascia, the “socii” are almost in even width, just slightly bulbous and spinulose apically, and the anellus bears a posterior process. In the female genitalia, the signa in S. expansus and in S. obliquifascia are typical for the genus (in fig. 41 viewed laterally), the longitudinal sclerite in S. expansus is a little shorter. The lamellae ante- and postvaginales are distinctly different (compare figs 40, 41). Type material. Holotype, 6, CHINA: Guangdong (IZCAS): Shixing, Chebaling, 330 m, 1–2.VIII.2013, coll.

The species is similar to S. diffusifascia and S. expansus externally. They all have yellowish brown wings and brown transverse bands and are hard to distinguish by external means only. A very clear character among the three species is that S. obliquifascia has two areoles in the forewing venation, but S. diffusifascia and S. expansus have only one. Moreover, the wings are narrower and slightly longer and the transverse lines are more strongly inclined in S. obliquifascia. A further good character of S. obliquifascia is the elongated, black marginal patch between M2 and M 3 in the forewing which is round and indistinct in the other two species.

Synegiodes punicearia Xue, 1992 Figs 3, 17, 27, 37 Synegiodes punicearia Xue, 1992, Iconography of forest insects in Hunan China: 825 [English translation p. 903], fig. 2663. Holotype ��, China: Hunan, Sangzhi, Tianping Shan (IZCAS). Diagnosis. The most distinctive difference of S. punicearia from S. sanguinaria and S. histrionaria is that the basal half of fore- and hindwings is densely colored pinkish-red throughout, as well as the broad postmedial bands which are separated in the forewings, confluent in the hindwings. The yellow band in between shows an irregular line of dots in the same color. This pattern is unmistakable. The vein R5 is shortly stalked with vein R2-4 from apical angle of the areole on the forewing, the same in S. sanguinaria and S. histrionaria, but about three times as long in S. ornata.

Synegiodes sanguinaria (Moore, 1868) Figs 1–2, 16, 26, 36 Anisodes sanguinaria Moore, 1868, Proc. zool. Soc. Lond. 1867 (3): 641. Syntypes Ƌ, India: Bengal (BMNH). Synegiodes sanguinaria: Swinhoe, 1892, Trans. ent. Soc. Lond. 1892: 11 (cited as diffusaria Moore, 1868). Synegioides [sic!] sanguinaria: Swinhoe, 1893, Ann. Mag. Nat. Hist. (6) 12, 147–157. Diagnosis. The color of the pattern elements on the wings is pink or pinkish red in S. sanguinaria, S. punicearia and S. histrionaria. The forewing postmedial area of S. sanguinaria and S. punicearia is composed of two separate patches, larger, more colorful and separated by a narrow band only in punicearia, smaller and mostly separated by a larger gap in S. sanguinaria (this gap may be suffused with pinkish dots or both patches connected along margin or even completely connected, see Figs 1–2). In S. histrionaria, the patches are connected in most specimens, a continuous postmedial line is present. But rarely the patches may be separated. In S. punicearia, the basal area of both, fore- and hind wings, until position of medial band are colored pinkish, while this area in S. sanguinaria is moderately to strongly suffused with pinkish, sometimes confluent dots. S. histrionaria has this basal area only very scarcely suffused. The ground color is a clear, light yellow in S. punicearia, pale yellow, semitransparent in S. sanguinaria and a deeper, not transparent yellow in S. histrionaria. In the male genitalia, the three pink-colored species are different from other congeneric species, as the “socii” are lacking. The uncus is stout, apically bilobed in S. sanguinaria, truncate in S. punicearia and S. histrionaria. In S. sanguinaria, the posterior margin of the anellus is more expanded than in S. punicearia and S. histrionaria. The general shape of the valva is similar in all three species. In the female genitalia, the lamella postvaginalis of S. sanguinaria and S. punicearia is weakly and irregularly sclerotized, while in S. histrionaria there is a strongly sclerotized, ventrally protruding, imbricate process, unique for the whole genus.
