( Figs 6–10 ) Material examined. Holotype : Male , India : Sikkim : Sangkalang , 27°30’21.0”N , 88°31’43.3”E , 1600 m , 13.v.2009 , Pandher & Parey ( NPC ) . Paratypes . 1 female , collection data same as of holotype . Himachal Pradesh ; Khajjiar , 32°33’20.9”N , 76°3’56.2”E , 1920 m , 20.v.2016 , 2 males , Pandher & Kaur ( NZC ) . Diagnosis. The male genitalia of this species are similar to those of Hydromanicus inferior Chantaramongkol & Malicky 1995 (reported from Thailand ), Hydm. punctosalis Mey 1996 ( Thailand , Vietnam ), and Hydm. fallax Mey 1996 from Vietnam . All of these species have long apical setose lobes of tergum X. However, in Hydm. sikkimensis sp. nov. the apicolateral lobes of segment IX are narrow (not as broad as in the other three species) and triangularly pointed in lateral view; preanal appendages are finger-like; the ventral margins of the preanal appendages are produced (in other species the dorsal margin is produced in lateral view); apical setose lobes of tergum X are very long, almost equal to the length of the body of tergum X in dorsal view, whereas the apical setose lobes of tergum X are smaller than the body of tergum X in dorsal view in other three species.

Description, adult male. Color in alcohol brown, dorsum of head dark brown, forewing membranes brown. Body covered with small, scattered yellow pubescence. Length from tip of head to apices of folded forewings about 8.25 mm. Maxillary palps each about 2 mm long, segment II slightly longer than III, segment V long, flexible; labial palps each 0.90 mm long. Forewings each 7 mm long; crossveins m-cu and cu far apart; Sc and R veins ending independently on wing margin, Cu2 and A separate to wing margin. Hind wings each about 4 mm long; Sc and R meeting at crossvein s before wing margin; stems of M and Cu1 separate; fork I present; median cell closed. Male genitalia ( Figs 6 – 10 ). Abdominal segment IX convex anterolaterally, more than twice as tall as long, apicolateral lobe tall, triangular, setose, anterior apodeme dividing segment IX into broad sternum and small dorsal tergum in lateral view; in dorsal view anterior margin concave, notched in middle; posterodorsal keel narrow, apically blunt, closed distally between pair of anterodorsal setose lobes of tergum X; with pair of apicolateral lobes. Preanal appendages long, slender basally, broadest in middle, covered with setae, pointed apically both in lateral and dorsal views. Depression between dorsum IX and tergum X not clearly demarcated. Tergum X long, broad basally, its apical setose lobes curved slightly ventrad, apically pointed in lateral view; in dorsal view tergum X quadrate, apical setose lobes digitiform, pointed, long, curved mesad, almost as long as body of tergum X in dorsal view, dorsal interlobular gap between them deep, anterodorsal setose lobes reduced to small, setose, transverse ridges on either side of the posteromedian keel of dorsum IX. Inferior appendages each two-segmented; basal segment (coxopodite) long, slender, apically broader in lateral view; in ventral view curved mesad; apical segment (harpago) small, broad basally, tapering and hooked dorsomesad at apex both in lateral and ventral views. Phallic apparatus with anterior opening (phallic foramen) wide; anterior part of phallotheca broad, ending distally in pair of regularly circular sclerous endothecal processes; pair of small irregular phallotremal sclerites located preapicomesally; tubular ejaculatory duct visible in lateral and ventral views (not shown in Fig. 9 ), joining endophallus at gonopore, endophallus ending apically at bases of pair of small sclerites (possibly vestigial phallicata). Distribution. India : Sikkim , Himachal Pradesh . Etymology. This species is named for the state from where the type was collected.
