Etymology. The specific epithet is an adjective and referring to the brown body colour of the new species ( Fig. 1A–B View FIGURE 1 ). Latin fuscus = brown.
Type material. Holotype ♀ ( ADSH57131 View Materials ) and paratype ♀ ( ADSH57132 View Materials ) from INDIA: Kerala: Thrissur, Chimmony Wildlife Sanctuary (10°25'06.80''N, 76°32'07.25''E; 709 m a.s.l.), 31.V.2013, leg. M.S. Pradeep, from ground, by hand. GoogleMaps
Diagnosis. Females of K. fusca sp. nov. are closely related to the females of K. princeps Deeleman-Reinhold, 2001 by having rectangular epigynal window, globular secondary spermathecae and posterolaterally located, diverging primary spermathecae, but can be distinguished from the latter by femur I with two prolateral spines (vs. absent in K. princeps ), contiguous secondary spermathecae (vs. widely spaced in K. princeps ), intertubular ducts with anterior twist (vs. absent in K. princeps ) and broad primary spermathecae (vs. narrow in K. princeps ) (cf. Figs 1I–J View FIGURE 1 , 2A–B View FIGURE 2 and Deeleman-Reinhold 2001: figs 394–395). Females of K. fusca sp. nov. can be distinguished from the females of K. armata (both share two strong prolateral spines on femur I) by lacking short, thorn-like ventral spines of femur I (vs. present in K. armata ), epigynal window with straight anterior margin (vs. M-shaped in K. armata ), and vulva with contiguous anterior parts (vs. widely spaced in K. armata ) (cf. Figs 1G, I View FIGURE 1 , 2A View FIGURE 2 and Fig. 3D, H View FIGURE 3 ).
Description. Female (holotype, Fig. 1A–H View FIGURE 1 ) in alcohol. Prosoma, chelicerae, labium, endites, palps and legs brownish; thoracic part with pale black patches; all leg femora, patellae and tibiae with black patches; opisthosoma greyish, with brown dorsal scutum; spinnerets pale yellow. Fovea narrow, longitudinal, short, dark ( Fig. 1A View FIGURE 1 ). AER slightly and PER moderately procurved, both in dorsal view ( Fig. 1A View FIGURE 1 ). Chilum present, inverted triangular, unipartite ( Fig. 1C View FIGURE 1 ). Cheliceral promargin with cluster of setae, with paired shaggy hairs, with three teeth ( Fig. 1E–F View FIGURE 1 ); retromargin with four denticles ( Fig. 1F View FIGURE 1 ). Sternum rebordered, with intercoxal extensions connected to carapace, sparsely covered with setae ( Fig. 1D View FIGURE 1 ). Metatarsus III–IV with weak preening brush ( Fig. 1H View FIGURE 1 , arrow 2); femur I with two ventrally directed prolateral spines ( Fig. 1G View FIGURE 1 , arrows 1); all tarsi without scopulae and with reduced claw tufts ( Fig. 1H View FIGURE 1 ). Palp with single claw. Opisthosoma oval, with complete dorsal scutum ( Fig. 1A–B View FIGURE 1 ). Body length 3.35. Carapace 1.52 long, 1.13 wide. Opisthosoma 1.83 long, 1.21 wide. Eye sizes and interdistances: ALE 0.08, AME 0.09, PLE 0.05, PME 0.04; ALE–PLE 0.03, AME–ALE 0.04, AME–AME 0.08, AME–PME 0.06, PME–PLE 0.12, PME–PME 0.14. Clypeus height at AMEs 0.19, at ALEs 0.10. Length of chelicerae 0.53. Length of palp and legs: Palp 1.79 [0.53, 0.25, 0.43, 0.58], I 5.59 [1.40, 0.49, 1.46, 1.51, 0.73], II 4.15 [1.13, 0.43, 0.97, 1.08, 0.54], III 3.56 [0.94, 0.42, 0.71, 0.98, 0.51], IV 5.17 [1.34, 0.46, 1.15, 1.52, 0.70]. Leg formula: 1423. Spination of palp: femur v 4, patella pld 1 do 1, tibia pl 1 pld 1 rlv 2, tarsus pl 1 rlv 1; legs: femur I pld 2, II–IV spineless; patella I–IV spineless; tibia I plv 8 rlv 8, II plv 7 rlv 7, III–IV spineless; metatarsus I plv 6 rlv 5, II plv 5 rlv 4, III–IV spineless; tarsus I–IV spineless. Genitalia ( Figs 1I–J View FIGURE 1 , 2A–B View FIGURE 2 ): epigyne weakly sclerotised, with wider than long epigynal window having small, rectangular, median flap with concave posterior margin ( Figs 1I View FIGURE 1 , 2A View FIGURE 2 ; EW, MF); anterior epigynal margin with paired lateral, downward directed conical protrusions, posterior margin convex ( Figs 1I View FIGURE 1 , 2A View FIGURE 2 ). Copulatory openings indistinct. Copulatory ducts short, thick, with slight median curvature, attached posteriorly to secondary spermathecae and anteriorly to intertubular ducts ( Figs 1J View FIGURE 1 , 2B View FIGURE 2 ; CD). Secondary spermathecae (bursae per Deeleman-Reinhold) globular, contiguous, connected to broad diverging primary spermathecae by obliquely oriented intertubular ducts having anterior twist ( Figs 1J View FIGURE 1 , 2B View FIGURE 2 ; ITD, ST I, ST II). Fertilization ducts narrow, anteriorly oriented, diverging ( Fig. 2B View FIGURE 2 ; FD).
