Nasoona indianа sp. nov.

Figs 1-3, 28-33

Holotype: Male; INDIA, West-Bengal, Darjeeling District, Ghoom, Tigerhill, southern slope, 2200-2300 m a.s.l., sifting in forest; 13.X.1978; leg. C. Besuchet & I. Löbl [#13].

Diagnosis: According to the male palpal conformation, N. indianа sp. nov. seems to be most similar to N. setifera (Tanasevitch, 1998), known from a single locality in the mountains of Nepal (Tanasevitch, 1998). The new species differs by the bifid distal apophysis of the convector, by the slender distal process of the paraconvector which was erroneously named the suprategular apophysis (Tanasevitch, 1998), as well as by the shape of the carapace. The carapace of N. indianа sp. nov. has a small, conical postocular elevation bearing a stout seta, while in N. setifera the carapace is armed with several stout, bent spines and a seta situated on a huge postocular elevation. The shape of the carapace and the structure of the embolic division of N. indianа sp. nov. is also similar to that of N. conica (Tanasevitch, 1998), known from high altitudes of the Nepalense Himalayas, but the new species differs clearly by the shape of its palpal tibia.

Etymology: The specific epithet, a Latinized adjective, is derived from the name of the country of origin, India.

Description: Male (holotype): Total length 2.01. Carapace 1.13 long, 0.90 wide, pale reddish brown, with grey radial stripes and a narrow margin. Behind posterior median eyes a conical elevation with a socket terminally, indicated with arrow in Fig. 3, probably for a large, stout seta which was lost in this specimen (Figs 1-3). Chelicerae 0.55 long, unmodified. Legs yellow. Leg I 4.38 long (1.25+0.30+1.13+10.05+0.65), IV 4.44 long (1.25+0.28+1.13+1.15+0.63). Chaetotaxy: spines mostly lost, but probably 2.2.1.1. Each metatarsus with a trichobothrium. TmI 0.71. Palp (Figs 28-33): Tibia slightly expanded distally, with several very short spinules terminally. Retrolateral side of tibia with a tooth-like tubercle, prolateral side with a small dark protuberance and two larger keel-shaped outgrowths. Proximal part of paracymbium narrow, distal part expanded and bearing several weak spines. Tegulum terminating in transparent protegulum. Distal suprategular apophysis short, wide, T-shaped distally, bearing a black, sharp tooth in middle. Embolus long and thin, forming a loop, radix reduced. Main body of convector relatively narrow, twisted, its distal apophysis well-sclerotized, black, bifid. Paraconvector large, complicated, with a long, sabre-shaped distal process. Abdomen 1.40 long, 0.88 wide, dorsal pattern as in Fig. 1.

Female: Unknown.

Distribution: Only known from the type locality in the mountains of West-Bengal, India.
