Figs 1–18
Type material. Holotype: ♁ (NRC-AA-4151) from INDIA: Maharashtra: Sindhudurg: Kudal, Vetal Bambarde Village (16°02’51”N, 74°42’45”E; 33m alt.), 2 July 2021, G. Kadam leg., from tree bark, by hand. Paratype: 1♀ (NRC-AA-4152), same data as for the holotype.
Etymology. The specific epithet is a noun in apposition and refers to the type locality.
Diagnosis. The new species is similar to S. gombakensis Zhang, Woon & Li, 2006, but differs in the male palp having a short VTA with apex directing at 11 o’clock in ventral view (vs. slightly longer, directing at 1 o’clock), a long and narrow RTA with a ventral extension at tip (vs. short, broad, without extension), a DTA fused with RTA at basal half part (vs. DTA & RTA with different origin point), a long and narrow conductor with tip serrated (vs. short, wide, without serration), the dorsum of cymbium covered with white hairs when alive (vs. orange) (compare Figs 1, 10–11 & 14–16 with figs 6–8 & 10 in Zhang, Woon & Li 2006); and the female epigynum with median septum comparatively narrow posteriorly (vs. wide), accessory gland large and round (vs. small and humped), spermathecae oval and wide (vs. nearly cylindrical and narrow) (compare Figs 12–13 & 17–18 with figs 4–5 in Zhang, Woon & Li 2006).

Chelicera promargin with three long teeth and retromargin with four closely spaced teeth. Legs III–IV notably paler than legs I–II, all legs with black streaks. Abdomen brown, hirsute, without any distinct pattern, except for longitudinal band along each side. Body length 7.85. Carapace 3.44 long, 2.55 wide. Abdomen 4.41 long, 1.77 wide. Eye size and ocular distance: AME 0.61, ALE 0.38, PME 0.20, PLE 0.33; AME–AME 0.01, AME–ALE 0.03, PME–PME 1.64, ALE–ALE 1.34, PLE–PLE 1.45, ALE-PLE 1.05. Chelicera 1.14 long. Clypeus height 0.10.

Pedipalp: DTA longer than RTA, falcate in shape; RTA three times broader than DTA with a slim ventral extension at tip (Figs 10–11 & 14–15); VTA thumb-like, with rounded apex directed at 11 o’clock ventral view; VTA with extension, nearly same length, with bend tip (Figs 11 & 15); tegulum with pronounced tegular furrow, located apicolaterally (Figs 10 & 14); embolus long, curved originating medio-prolaterally at 9 o’clock position, masked behind the conductor (Figs 10 & 14); conductor translucent long, broad and curved, serrated near tip (Figs 10 & 14, arrow 1 in Fig. 14).
Female (paratype, colour in alcohol): As male except, a tuft of white hairs beneath to posterior eyes absent. Chelicerae 3/4th region black. Abdomen darker. Body length 8.75.
