(Figs 1–5)
Material examined. Holotype: Male, India: Sikkim; Chungthang, 27°36’14.04’’N, 88°38’47.04’’E, 2200 m, 15.ix.2009, Pandher & Parey, (NPC). Paratypes. 2 females, collection data same as of holotype.
Diagnosis. This species is unique in having reduced preanal appendages in its male genitalia. The male genitalia of this species are similar to those of Hydromanicus hermosus Banks 1934 and Hydm. elam Malicky 2009 (both from Borneo) in lateral view. However, in Hydm. religiosus the apicolateral lobes of segment IX are very pointed and produced in lateral view; tergum X is broad in dorsal view; the posterodorsal keel of segment IX is open. In Hydm. hermosus and Hydm. elam the apicolateral lobes of segment IX are not strongly produced and are slightly rounded in lateral view; tergum X is not as broad as in Hydm. religiosus in dorsal view; the posterodorsal keel of segment IX is open in Hydm. elam but closed in Hydm. hermosus in dorsal view.
Description, adult male. Color in alcohol brown. Wing membrane light brown. Length from tip of head to apices of folded forewings about 10 mm. Forewings each 8.50 mm long, venation typical for genus; crossveins m-cu and cu separated; Sc and R running independently to wing margin; Cu2 and A separately joining wing margin. Hind wings each about 6.50 mm long; fork I present; median cell closed.
Male genitalia (Figs 1–5). Abdominal segment IX long, tall, convex anterolaterally, apicolateral lobe on each posterolateral margin broad and triangularly produced; anterior apodeme dividing segment IX into broad sternum and small dorsal tergum in lateral view; in dorsal view anterior margin concave; posterodorsal keel (MK) broad, triangular, open distally. Preanal appendages (PA) lobe-like, each with narrow base, sparsely setose, not arising on elevated tubercle. Depression between dorsum IX and tergum X slightly demarcated. Tergum X broad, quadrate both in lateral and dorsal views, apically pointed; apical setose lobes (ASLX) seen in profile at apicolateral corners in dorsal view, capitate apically in lateral view; dorsal inter-lobular gap (ILG) small and delimited by apical setose lobes; anterodorsal setose lobes (ADSLX) reduced. Inferior appendages (INF) each two-segmented: basal segment (coxopodite) long, slender, and sinuous in lateral view, curved mesad in ventral view; apical segment (harpago) small, broad basally and slightly narrowing to mesally hooked apex in ventral view. Externally, basal 1/4 of phallic apparatus (phallotheca) directed dorsad then bent caudad; posterior part of phallotheca horizontal, slightly sinuous, ending distally in pair of sclerous endothecal processes, regularly semicircular in dorsal view; pair of small, irregular sclerites (possibly representing vestigial phallicata) located between and beneath sclerous endothecal processes. Internally, ejaculatory duct (not shown) narrow, tubular, entering phallus through anterior phallic foramen and ending at gonopore near base of phallus; larger and retracted and inverted membranous endophallus extending from gonopore posterad to pair of small sclerites. Broad and pointed pair of sclerous endothecal processes (apicoventral keels) dominating apex of phallus in lateral view.
Distribution. India: Sikkim.
Etymology. This species is named with respect to the religious importance of the type locality. According to the belief of the local people in Chungthang, the First Sikh Guru visited here in 1509 AD. He blessed this place and spread rice grains as there was no food grown locally. This is the only place in North Sikkim where rice cultivation occurs with his blessings.
