Figs 4–6, 7

Type material. Holotype: Male, Huzhi Cave [24°49.456′N, 108°05.527′E], Sancai Village, Shuiyuan Town, Huanjiang County, Guangxi Province, China, 13 July 2010, leg. X. Wei, S. Zhu, H. Xu and Y. Chen. Paratypes: 2 males and 3 female, same data as holotype.

Etymology. The specific name derived from the name of type locality.

Diagnosis. This species resembles K. liuzhouensis Yao & Li, 2010 in having a similar dorsal shape of the prosoma (Fig 4 C) and similar shape of bulb, but can be distinguished by different shape of apophyses of male chelicerae (Fig 6 C), different distal elements of procursus (Figs 4 A–B, D, 6A–B), which are shorter than the bulb, and the nearly triangular shape of the lateral pore plates of the vulva (Figs 5 A–B, 6D–E).

Description. Male (holotype): Total length 2.05 (2.25 with clypeus), prosoma length 0.74, width 0.93; opisthosoma length 1.31, width 1.02. Leg I: 18.59 (4.80 + 0.45 + 4.81 + 6.79 + 2.50), leg II: 11.93 (3.33 + 0.40 + 2.88 + 4.05 + 1.27), leg III: 9.51 (2.85 + 0.36 + 2.24 + 3.01 + 1.05), leg IV: 11.77 (3.51 + 0.39 + 2.95 + 4.05 + 0.87); tibia I L/d: 51. Habitus as in Fig 4 C. Dorsal shield of prosoma yellowish, with black margins and a median black stripe behind ocular area. Sternum black. Legs yellowish. Opisthosoma grey with large black spots dorsally and ventrally. Distance PME–PME 0.10, diameter PME 0.12, distance PME–ALE 0.02, AME absent. Ocular area slightly elevated and separated from Prosoma. Thoracic furrow shallow but distinct. Sternum slightly wider than long. Chelicerae as in Fig 6 C, with a pair of long, slightly hooked frontal apophyses (tips close together), a pair of very small, triangular anteromedian apophyses, a pair of strong proximal apophyses provided with lateral elliptic ledges and a pair of small distal apophyses on the anterolateral surface. Pedipalpi as in Figs 4 A–B and 6A–B; trochanter with a retrolateral apophysis and a small ventral apophysis; femur with a retrolateral apophysis; patella large, procursus simple proximally, no longer than bulb, complex distally, with an apophysis retrodistally (Figs 4 B and 6B) and a membranous apophysis prolaterally (Figs 4 A and 6A); bulb simple, no other apophyses except for embolus. All metatarsi with short, vertical hairs (most hairs situated dorsally and laterally), without spines and curved hairs; tarsus I with more than 20 pseudosegments, of which the distal 13 pseudosegments distinct.

Variation. Tibia I length in other males (n=2): 3.76–4.81 (mean: 4.38).

Female. Similar to male, habitus as in Figs 5 C–D. Leg I lost in all female specimens. Epigynum brown (Figs 5 A and 6D), without pockets. Vulva (Figs 5 B and 6E) with two nearly triangular lateral pore plates. Distribution. The species is known only from the type locality (Fig. 7).
