Description.

Male (IZCAS-Ar 41048). Total length 0.60. Carapace 0.28 long, 0.24 wide, 0.36 high. Clypeus 0.20 high. Sternum 0.16 long, 0.16 wide. Abdomen 0.28 long, 0.28 wide, 0.48 high. Length of legs: I 1.04 (0.30, 0.12, 0.24, 0.14, 0.24); II 0.86 (0.24, 0.12, 0.20, 0.10, 0.20); III 0.66 (0.16, 0.10, 0.12, 0.10, 0.18); IV 0.82 (0.26, 0.10, 0.16, 0.14, 0.16).

Somatic characters (Fig. 17A-C and G-I). Colouration: body dark, nearly black. Legs light brown, with black pigmentation. Prosoma: carapace longer and higher than wide. Cephalic apex at PME position. ALE> PLE = PME, PME separated by ca. half a radius, PER recurved. Clypeus concave, paired notches separated by more than width of PME (Fig. 17G and H). Labium short, with shallow notch. Legs: each patella with 1 long dorsal seta, each tibia with 2 long dorsal setae. Opisthosoma: shape as in K. maiguai sp. nov., spinnerets dark.

Palp (Fig. 18A and B): strongly sclerotised. Proximal cymbial process (CP1) small, sharp, needle-like, distal cymbial process (CP2) large, hooked. Cymbial apophysis (CP) truncated, with 2 distal long setae. Distal bifurcation of median apophysis located directly below the hooked CP2 (Fig. 18A). Tegulum translucent, weakly rugose, with a triangular apical process. Embolus longer than median apophysis, robust, horn-like, strongly sclerotised, gradually tapering, bent at nearly proximal ⅓, forked at terminus.

Female (IZCAS-Ar 41049). Total length 0.80. Carapace 0.32 long, 0.28 wide, 0.32 high. Clypeus 0.10 high. Sternum 0.20 long, 0.20 wide. Abdomen 0.52 long, 0.52 wide, 0.60 high. Length of legs: I 1.20 (0.40, 0.10, 0.30, 0.18, 0.22); II 0.90 (0.22, 0.12, 0.22, 0.14, 0.20); III 0.74 (0.20, 0.10, 0.14, 0.10, 0.20); IV 0.86 (0.26, 0.10, 0.18, 0.12, 0.20).

Somatic characters (Fig. 17D-F). Colouration: same as in male. Prosoma: carapace longer than wide, as long as high. Cephalic part lower than in male, flat dorsally. PER slightly recurved. Legs: spination of each leg as in male. Opisthosoma: laterally oviform. Spinnerets Located ventrally.

Epigyne (Fig. 18C-F): plate wider than long, strongly sclerotised. Scape wider than long, slightly protruded. Spermathecae globose, separated by more than 3.5 diameters. Copulatory ducts long, their proximal parts enlarged, forming a broad, inverted, subtriangular atrium, with knob-shaped lateral humps; middle part coiled more than 5 times; distal part connected longitudinally to spermatheca. Fertilisation duct slightly bent, runs along lateral wall of atrium, originating above coiled part of copulatory duct.
