INTRODUCTION
During the last several years, a number of new Lithosiini species were described from Indochina by the second and third authors of the present paper (Dubatolov & Bucsek, 2013;2014;2016).In many cases, species were described on the basis of males only, and in some small species male vesici were not everted and described.During our studies on Lithosiini of Indochina, additional materials on some of these recently described species were obtained, and the male genitalia of some small-sized species were re-prepared and mounted in euparal by the senior author of the present paper.All the newly obtained data are presented below.

MATERIAL AND METHODS
The paper is based on the materials of collections of the Siberian Zoological Museum of the Institute of Systematics and Ecology of Animals, Siberian Branch of RAS (SZMN, Novosibirsk, Russia), the Natural History Museum, London (formerly British Museum of Natural History, NHM, London, Great Britain) and the private collection of Anton Volynkin (CAV, Barnaul, Russia).The genitalia were dissected and mounted in euparal on glass slides.Photos of imago where taken using the camera Nikon D3100/AF-S Nikkor, 18-55 mm.Photos of the genitalia where taken by same camera attached to a microscope with an LM-scope adapter, and further processed by Adobe Photoshop CS4® software.
Note.The type series of the species includes both males and females, but the male genitalia without everted vesica were described and illustrated only (Dubatolov & Bucsek, 2013).
Description of male aedeagus (Fig. 16).Aedeagus straight, short and broad; vesica short and broad, with small, conical and membranous dorsal subbasal diverticulum, large bulbous lateral diverticulum having strong scobination, several smaller diverticuli of different shape and size with scobination, and bunch of two-three strong spearhead-like cornuti that situated apically on one strongly sclerotized bundle-like base.
Description of female genitalia (Fig. 26).Ovipositor short and broad, papillae anales rectangular; apophyses anteriores and posteriores long and thin, with broadened triangular bases.Ostium bursae situated in the middle of 7th sternite; antrum rugose, with two lateral triangular lateral lobes; ductus bursae short, rugose, weakly sclerotized; corpus bursae pear-like, with numerous thorns in anterior section and laterally at the left side, and three large bands of strong spines in posterior and medial sections; appendix bursae large, globular, strongly rugose-sclerotized, situated laterally at the right side.7th sternite with very small lateral pockets.
Distribution.The species is known from Vietnam (Kon Tum and Lam Dong provinces).
Note.The type series of the species includes both sexes, but the female genitalia were not described and illustrated (Dubatolov & Bucsek, 2013).
Description of female genitalia (Fig. 27).Ovipositor short and broad, papillae anales rectangular; apophyses anteriores and posteriores long and thin, with broadened triangular bases.Ostium bursae situated in the posterior third of 7th sternite; antrum rugose, narrow; ductus bursae very short, membranous; corpus bursae kidney-like, its anterior two-thirds with numerous thorns of diffrent size; posterior third of corpus bursae strongly rugose-sclerotized; appendix bursae large, globular, strongly rugose-sclerotized, situated laterally at the right side.7th sternite with very large lateral pockets.
Diagnosis.In the original description (Dubatolov & Bucsek, 2013), the species was not compared with any other Lyclene species, its characteristic hindwing dark margin was mentioned only.There is one more species with close appearance, Lyclene punctata (Rothschild, 1913), comb.nov.(Figs 5,19) known from eastern India (Meghalaya, Khasi Hills), but it has strongly different male genitalia structure.According to the male genitalia structure (presence of the weakly sclerotized dorsal crest on apical part of costa, configuration of diverticuli in vesica, and presence of a bunch of several strong claw-like cornuti on a sclerotised plate in the distal part of vesica), L. kosterini (Fig. 17) is similar to Lyclene angulifera Holloway, 2001 (Fig. 18) known from Sundaland, but differs externally by the larger size, longer forewings and the different wing pattern; the male genitalia of L. kosterini (Fig. 17) differ from those of L. angulifera (Fig. 18) by the valva medially broader, the dorsal crest of apical part of costa very short and broad, the valva apex triangular, the distal saccular process very short and thin, the ventral subbasal diverticulum broader, the scobination of medial diverticulum weaker, and the cornuti slightly shorter.
Notes.In NHM collection, besides the specimen having the red type-label, there are three more specimens with the same geographic label from the Rothschild's collection, but not marked as types.In the original description (Rothschild, 1913), the number of types was not mentioned.Hampson (1914) recorded as "Type" only one male specimen, that is equivalent to a present-day lectotype designation.Therefore the specimen with a type-label (Fig. 5) is treated here as the lectotype.The species has an appearance typical for the genus Lyclene, but long time it was treated by authors (Strand, 1922;Kirti et al., 2014) as a member of the genus Asura.Our examination of its male genitalia confirmed its belonging to the genus Lyclene, so the new combination is established here: Lyclene punctata (Rothschild, 1913), comb.nov.The male genitalia of the species (Fig. 19) are very characteristic in the aedeagus strongly curved and the vesica structure, and differ strongly from those of externally close L. kosterini that has a similar broad blackish hindwing margin.
Description of male genitalia (Fig. 19).Uncus long, narrow, laterally flattened, slightly curved dorsoventrally, apically pointed; scaphium thin and weakly sclerotized; subscaphium as narrow field of weak scobination; tegumen short and broad, penicular lobes broad, elliptical; manica very long, consists of two very long, narrow and strongly sclerotized lobes with strong dentation; justa broad, weakly sclerotized, band-like; vinculum large, U-shaped.Valva broad, in border of distal third weakly sclerotized and curved dorsally, its distal third broad and rounded; sacculus very narrow and strongly sclerotized, its distal process long but not reaching the calva apex, strongly separated from the distal lobe of valva, heavily sclerotized, distally slightly cirved dorsally and pointed apically.Aedeagus long, narrow, strongly curved dorsally; vesica curved dorsally, with small conical subbasal ventral diverticulum, small conical subapical diverticulum, one strong thorn-like cornutus medially, and long and narrow diverticulum projected ventrally and having one strong thorn-like cornutus apically.
Note.The species was described on the basis of a single male of bad condition having weather-stained whitish wing coloration (Fig. 7).Fresh specimens of both sexes collected in Chiang Mai province (Figs 8, 9) have bright light yellow forewing coloration.Females were collected for the first time, they have forewing pattern very similar to that of males, but broader forewing and slightly larger size (Fig. 9).Male genitalia of newly collected specimens (Fig. 22) have no differences from those of the holotype.Female genitalia are described here for the first time.
Description of female genitalia (Fig. 28).Ovipositor short, broadly conical; apophyses anteriores and posteriores long and thin; ostium bursae very broad; antrum with rugose margins and deep narrow concave medially; ductus bursae long, broad, narrowed anteriorly, heavily sclerotized, its anterior section with scobination; corpus bursae curved, pear-like, its anterior section with spinulose scobination, medial section with two short bands of very large spinules, posterior section weakly sclerotized.
Distribution.The species is known from North Thailand (Phitsanulok and Chiang Mai provinces).Note.The species was described on the basis of a single male.Its male genitalia were described and illustrated without everted vesica (Dubatolov & Bucsek, 2013).

Lyclene kepica
Diagnosis.Externally, the species resembles Himalayan L. obsoleta Moore, 1878 (the comparison was given by Dubatolov & Bucsek, 2013), but the valva configuration resembles that of L. unguifera Holloway, 2001 (Figs 11, 21).Nevertheless, kepica and unguifera are not related species because of presence of long costal lobe with dentate ventral margin, and strongly dentate lobes on transtilla in L. kepica, the features are unique among known Lyclene species.In addition, the male genitalia of L. kepica differ from those of L. unguifera by the uncus longer and evenly narrowed apically (in unguifera the uncus apex with a claw-like tip), the juxta much broader, the costa almost straight (in unguifera the costa with a strong fold apically), the apical lobe of valva shorter, the sacculus narrower, the distal saccular process much narrower, the aedeagus longer and narrower, the carina scobination presented, the vesica diverticuli configuration different, and presence of only thorn-like cornutus in the ventral diverticulum (whereas in unguifera a very large claw-like subbasal cornutus and a field of several short spike-like cornuti in the apical diverticulum are present).
Description of male aedeagus (Fig. 20).Aedeagus long and narrow, straight, with scobination in distall end.Vesica broad and short, consists of one large membranous ventral diverticulum with strong claw-like cornutus, one small membranous and one larger scobinated medio-apical diverticui, and one small conical New data on some of the recently described Lithosiini species 329 Biological Bulletin of Bogdan Chmelnitskiy Melitopol State Pedagogical University, 6 ( 3), 2016 membranous distal diverticulum; basal plate of ductus ejaculatorius very narrow, weakly sclerotized, situated dorsally.
Distribution.S Cambodia, Kep province.The species is known from its type locality only.
Note.The species was described on the basis of a single male.Its male genitalia were described and illustrated without everted vesica (Dubatolov & Bucsek, 2016).
Description of male aedeagus (Fig. 23).Aedeagus long and narrow, almost straight.Vesica elongated, narrow, curved dorsally, broadened medially, with one ventral subbasal longitudinal band of more than 10 strong spike-like cornuti of size expanding distally along the band, medio-distal ventral bunch of several strong spikelike cornuti, and subapical transverse band of 6 strong spike-like cornuti.
Distribution.Central Vietnam (Kon Tum province) and North Thailand (Chiang Mai province).The species is reported here for Thailand for the first time.
Note.The species was described on the basis of a single male in bad condition.Its male genitalia were described and illustrated without everted vesica (Dubatolov & Bucsek, 2013).
Description of male aedeagus (Fig. 25).Aedeagus short and very broad.Vesica short, membranous, with one dorsal subbasal conical diverticulum, and one twisted apical diverticulum with bunch of long and thin cornuti; distal section of vesica and ductus ejaculatorius broad, projected ventrally backwards.
Distribution.Central and South Vietnam (Kon Tum, Gia Lai and Lam dong provinces).
