Type material.

Holotype: male (AS19.4895 = NCBS IBC-BP847) in NCBS from India: Karnataka: Kodagu: Yavakapadi, Honey Valley area, 12.2224°N, 75.6553°E, 1045 m elev., 27 June 2019, W. Maddison WPM#19-083. Paratypes: Female (AS19.4934 = NCBS IBC-BP848) in NCBS with data as holotype except 12.2214°N, 75.6556°E and 1130 m elev. One male and one female in CATE from India: Kerala: along state highway 21 east of Chalakudy, 10.296°N, 76.685°E, 26 June 2021, Vishnudas & Sudhikumar CATE9826705. One female with same data but 17 July 2021.

Etymology.

From the Sanskrit for 'from the Western Ghats mountains’, where this species lives.

Diagnosis.

Embolus differs in shape from that of the similar K. leucomelas : embolus tip with retrolateral flange less distinct and smaller (Figs 64 View Figures 46–72 , 66-69 View Figures 46–72 ), and prolateral edge of embolus curves gently to the distal to make the embolus appear to be leaning slightly to the retrolateral (Figs 64 View Figures 46–72 , 68 View Figures 46–72 , 69 View Figures 46–72 ). Compared to K. leucomelas , the longitudinal pale bands on body less distinct, and the carapace is narrower.

Description.

Male (based on holotype). Carapace length 3.0, width 2.1; abdomen length 3.9. Carapace: Relatively flat; area around fovea slightly depressed. Dark brown, loosely clothed with white scales below and behind PLE forming an indistinct longitudinal band on each side. Clypeus very narrow, dark, with black setae. Chelicerae diverging slightly, lacking the distinct bulge of K. frenata and K. leucomelas , but with hair-bearing tubercles. Narrow stripes of white scales form inverted V as in other Kelawakaju frenata group species (Fig. 83 View Figures 82–89 ). Two promarginal and one large triangular retromarginal teeth, as in K. frenata (Fig. 8 View Figures 2–9 ). Palp dark to light brown, with white scales and long white hairs. The prolateral hairs on the tibia appear as a distinct long brush projecting medially (Figs 83 View Figures 82–89 , 84 View Figures 82–89 ). Embolus with prolateral edge gently curved. Retrolateral flange near tip fairly large, but emerges gradually, without strong cleft near tip (Figs 66 View Figures 46–72 , 67 View Figures 46–72 ). Endite subrectangular, with no projection, dark brown. Legs: First leg dark to light brown, with loose patches of white setae (Figs 82 View Figures 82–89 , 85 View Figures 82–89 ). Posterior legs paler, darker on femora and near the joints. Length of femur I 2.0, II 1.5, III 1.4, IV 1.7; patella + tibia I 3.1, II 2.0, III 1.7, IV 2.3; metatarsus + tarsus I 2.0, II 1.5, III 1.5, IV 1.7. Leg spination reduced: femur I d1-0-0, p1-1-0, II d1-1-0, p0-0-1, III d1-1-2, 0, IV d1-1-0, 0; patella I-IV 0; tibia I v2-2-2 (asymmetrical), II v1r-1r-1p, III 0, IV 0; metatarsus I-II v2-2, III v0-0-1p, IV v0-0-1p. Abdomen narrow, dark medially, paler and mottled laterally.

Female (based on specimen NCBS IBC-BP848). Carapace length 4.0, width 2.9; abdomen length 5.0. Carapace, Clypeus as in male. Chelicerae dark, with black hairs arising from small tubercles. Two promarginal and one larger triangular retromarginal teeth. Legs: First leg darkest, but all legs have dark patches, especially the sides of the femora and near the joints. Length of femur I 2.4, II 1.9, III 1.8, IV 2.1; patella + tibia I 3.3, II 2.5, III 2.3, IV 3.3; metatarsus + tarsus I 2.1, II 1.6, III 2.0, IV 2.3. Leg spination reduced: femur I d0-1-0, p0-3-0 or 2-0, II d1-1-0, p0-0-1, III d1-1-0, p0-0-1, IV d1-1-0, 0; patella I-IV 0; tibia I v2-2-2 (asymmetrical), II v1r-1r-1p, III 0, IV 0; metatarsus I-II v2-2, III v0-0-1p, IV v0-0-1p. Abdomen long, narrow, dark medially and pale laterally. Epigyne with two crescent-shaped openings behind a pale desclerotized area (Fig. 71 View Figures 46–72 ).

Natural history.

The holotype and female paratype from Kodagu were found under loose bark of large trees standing in a field, beside a small road. The specimens from Kerala were found in crevices in the bark of Swietenia mahogany trees.
