Lepidostoma sonmargae sp. n.

( Figs 13–18 View Figs 13–18 )

Description: Golden brown. Scapes ( Fig. 13 View Figs 13–18 ) each 3.88 mm, with two small subbasal processes dorsally, more distal process slightly curved. Maxillary palps ( Fig. 17 View Figs 13–18 ) 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 View Figs 13–18 .

Male genitalia ( Figs 13–16 View Figs 13–18 ): 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 View Figs 13–18 .

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.
