Lepidostoma himachalicum sp. nov.

( Figs. 7–12 )

Male: Golden brown. Scapes ( Fig. 12 ) each 2.88 mm., with 2 posterior processes, basal process slightly shorter than apical process, apex membranous. Maxillary palps ( Fig.12 ) long, each 0.96 mm, 2-segmented, basal segment 3 times longer than terminal segment. Length of each forewing 10 mm. Wing venation and setae as in Fig. 11 . Male Genitalia ( Figs. 7–10 ): Apical margin of segment IX pentagonal in dorsal view. Tergum X forming pair of spanner-shaped plates, each deeply notched apicolaterally. Inferior appendages each 2- segmented, first article long and broad, second article shorter and shallowly excised at its apex. Phallus slender; phallobase truncate apically; parameres set across genitalia; phallicata slender, slanting downward.

Diagnosis. This species differs from other species of the L. ferox Branch in having the halves of segment X spanner-shaped and apicolaterally notched.

Etymology. The name of the species is based on the state “Himachal Pradesh” from where the type specimen was collected.

Material examined. Holotype 3 INDIA: Himachal Pradesh, Raskar 1700 m, 03- vii-2009. Material deposited in the Museum of the Department of Zoology, Punjabi University, Patiala. India.
