Hydromanicus clavatus sp. nov.

( Figs. 11–15 View FIGURES 11–15 )

Material examined. Holotype; male, India: Uttarakhand; Mori , 1200 m, 31°01’10.2”N 78°02’37.8”E, 29-ix-2008, Pandher & Parey, ( NPC). GoogleMaps

Paratypes. 1 male, 2 females, collection data same as of holotype.

Diagnosis. In the presence of truncate apical segment of each inferior appendage, this species also is similar to Hy. luctuosus . However, the apicoventral setose lobe of tergum X is pectinate and broad apically and the preanal appendages are somewhat clavate in lateral view in H. clavatus sp. nov., setting this species apart from Hy. luctuosus and Hy. betteni .

Description, adult male. Color in alcohol fuscous, wing light brown, legs and maxillary palps pale yellow, dorsum of head coal black, forewing membrane with circular, irregular reticulate patches. Length from tip of head to apices of folded forewings about 10 mm; maxillary palps each 2.50 mm long; segment II slightly longer than III, segment V almost equal to I–IV together; labial palps each 0.90 mm long. Length of each forewing about 9 mm; crossveins m-cu and cu separate; Sc and R distinct; Cu 2 and A reaching wing margin separately. Length of each hind wing about 6.25 mm; fork I present; median cell open; Sc and R fusing before costa at crossvein s; stem of M and Cu 1 separate.

Male genitalia ( Figs. 11–15 View FIGURES 11–15 ). Abdominal segment IX in lateral view convex anterolaterally, longitudinally long, apical lobe on posterolateral margin broad, rounded, setose, its posterior spine row continuous, anterior apodeme dividing segment IX into broad sternum & small dorsal tergum; in dorsal view anterior margin very broadly concave, posteromedian keel broad, apically triangular, open distally, with pair of subapicolateral lobes. Preanal appendages forming pair of long processes, each arising on elevated base, somewhat clavate with narrow base, broadest subapically, pointed apically, covered by setae. Depression between segment IX and tergum X slightly demarcated. Tergum X long, narrow, with slightly rounded subapicoventral margins and pointed apex in lateral view; in dorsal view quadrate with pair of rounded subapicolateral protuberances; its apicoventral setose lobes capitate apically, dorsal interlobular gap deep, wide, demarcated by apicoventral setose lobes laterally, apicodorsal setose lobes reduced to pair of small setose longitudinal areas anterior of subapicolateral protuberances. Inferior appendages each two-segmented; basal segment (coxopodite) long, slender, apically broadened in lateral view; in ventral view curved mesad; apical segment (harpago) small, broad basally, constricted pre-apically, produced apicomesally and blunt apically in lateral and ventral. Phallic apparatus with anterior opening (phallic foramen) ventral, anterior part of phallotheca horizontal and very broad, narrowing before subapicoventral keel; phallotheca ending distally in semicircular sclerous endothecal process; median rim thickened, incurving; with pair of small irregular phallotremal sclerites located mesally before apex; endophallus ending anteriorly in narrow tube with gonopore; broadly rounded, ovoid subapical ventral keel of phallotheca visible in lateral view.

Distribution. India: Uttarakhand.

Etymology. The species name is derived from the somewhat clavate shape of the preanal appendages.
