Saini, Malkiat S. & Parey, Sajad H., 2011, Four new species of the genus Lepidostoma Rambur (Trichoptera: Lepidostomatidae) from the Indian Himalayas, with a checklist to its Indian species, Zootaxa 3062, pp. 25-36 : 26-28

Lepidostoma kashmiricum sp. nov.

( Figs. 1–6 )

Male: Brown. Scapes ( Fig. 6 ) each 1.44 mm, with 2 processes, both processes situated posteriorly about midlength, basal process slightly shorter than apical process. Maxillary palps ( Fig. 6 ) each 0.96 mm, 2-segmented, basal segment short, apical segment twice as long basal segment, apex curved. Average length of each forewing 9.7 mm. Wing venation as in Fig. 5 .

Male genitalia ( Figs. 1–4 ): Segment IX triangular in dorsal view. Segment X, produced into 2 long, slender, finger-like, lateral processes and 2 short and conical, mesal processes. Inferior appendages each single-segmented, its apex 3-branched; outer main branch with tuft of apical setae, middle branch (probably second article) longer than others and clubbed apically, ventromesal branch broad and with acute apex curved somewhat laterad; also, basodorsal process directed dorsad apically. Phallus long and slanting downwards, phallobase apically rounded; parameres present, parallel with one another; phallicata apically dilated.

Diagnosis. The wing venation of this species closely resembles with that of L. armatum (Ulmer) in the L. ferox Branch. However , the new species can be differentiated from the latter by having longer and more slender lateral processes and shorter and conical mesal processes of segment X. Inferior appendages are each apparently 3- branched, with the central branch (probably second article) longer than the remaining 2. Scapes each have the basal process smaller than the apical process.

Etymology. The name of the species is based on the state Jammu & Kashmir from where the type specimen was collected.

Material examined. Holotype 3 INDIA: Jammu & Kashmir, Pahalgam, 2100 m, 14-viii-2009. Paratypes: West Bengal, Darjeeling, 2200 m, 14-iv-2009, 13. Sikkim, Singhik, 1400 m, 14-ix-2009, 23. All material deposited in the Museum of the Department of Zoology, Punjabi University, Patiala, India.
