S. text Acta Zoologica Academiae Scientiarum Hungaricae 2012 2012-05-10 58 1 31 40 journal article 106152 10.5281/zenodo.5732051 c2065769-4c1e-45a3-88ed-dd5426b58267 2064-2474 5732051 72B1F588-06E2-44A4-98A8-40F279D9D274 Lepidostoma sonmargae sp. n. ( Figs 13–18 ) Description: Golden brown. Scapes ( Fig. 13 ) each 3.88 mm , with two small subbasal processes dorsally, more distal process slightly curved. Maxillary palps ( Fig. 17 ) each 0.97 mm , two-segmented, 1st segment slightly thicker and longer than apical segment, covered with mixed hairs and scales. Length of each forewing 7.9 mm . Wing venation as in Figure 18 . Male genitalia ( Figs 13–16 ): Tergum IX apicodorsally produced into triangular projection. Segment X with narrow excision at its centre reaching to its base. Both dorsolateral and mesal processes well developed: dorsolateral processes triangular in dorsal view, mesal processes rounded and serrate in lateral view both pairs of processes appearing subquadrate. Inferior appendages each two-segmented, 1st segment apically rounded, 2nd segment apically excised in dorsal view; basodorsal processes absent. Phallus shorter than parameres, phallobase with anteroventral flange; paramere spines apically pointed and diverging from one another. Wing venation of this species is similar to that of L. nagana and is given in Figure 18 . Diagnosis: The male of this species appears close to that of Lepidostoma nagana MOSELY, but differs from the latter by having segment IX triangular apicodorsally, not truncate. Segment X of this species has its dorsolateral processes triangular, not rounded; when seen laterally, both dorsolateral and mesal processes are of the same length, not of unequal length. The scape of each antenna is relatively shorter than in L. nagana , the basal process of the scape is straight, not angled. The basal segment of each maxillary palp is relatively shorter than in L. nagana . Material : India : Holotype : male, ( MDZ ), Jammu & Kashmir , Sonmarg , 2900 m , 11-viii-2008 . Female and immature stages: Unknown. Etymology: The name of the species is based on the locality from where the type specimen was collected.
