Type material. Holotype: Male (IZCAS-Ar39653), Menshuiluxie Cave (25°38′N, 108°2′E, elevation 520 m), Ban- zhai Village , Dongtang Town, Libo County, Guizhou, China, 20 June 2011, Z. Zha leg. GoogleMaps Paratype: 1 female (IZ- CAS-Ar39654), same data as holotype GoogleMaps .
Etymology. The specific name refers to the type locality and is a noun in apposition.
Diagnosis. This species resembles K. sancai Wei & Xu, 2014 (see Wei & Xu 2014: 184, f. 4A–D, 5A–D, 6A–E) with similar procursus ( Figs 3 View FIGURE 3 C–D) and epigynum ( Fig. 4A View FIGURE 4 ), but can be distinguished by short proximo-lateral apophyses on male chelicerae ( Figs 4 View FIGURE 4 C–D) and triangular pore plates ( Fig. 4B View FIGURE 4 ).
Description. Male (holotype): Total length 2.28 (2.38 with clypeus), carapace 0.93 long, 1.05 wide, opisthosoma 1.35 long, 1.14 wide. Leg I: 20.81 (5.15 + 0.42 +5.13 + 7.70 + 2.41), leg II: 12.66 (3.52 + 0.40 + 2.98 + 4.48 + 1.28), leg III: 9.74 (2.86 + 0.35 + 2.31 + 3.34 + 0.88), leg IV: 12.29 (3.70 + 0.39 + 2.92 + 4.43 + 0.85); tibia I L/d: 44. Habitus as in Figs 4 View FIGURE 4 E–F. Carapace yellowish, with black margins and wide, black median stripe; sternum black. Legs brownish, but slightly whitish on distal parts of femora and tibiae, with distinct darker rings on subdistal parts of femora and on proximal and subdistal parts of tibiae. Opisthosoma yellowish, with large black spots. Distance PME-PME 0.13, diameter PME 0.14, distance PME-ALE 0.02, AME absent. Ocular area slightly elevated and separated from rest of carapace. Thoracic furrow shallow, but distinct. Clypeus unmodified. Sternum slightly wider than long (0.67/0.61). Chelicerae ( Figs 4 View FIGURE 4 C–D) with pair of small proximo-ectal apophyses, pair of small distal apophyses on ectal surface, pair of small frontal apophyses (arrows in Figs 4 View FIGURE 4 C–D), and pair of long, hooked frontal apophyses (tips close together) provided with scales each. Pedipalps as in Figs 3 View FIGURE 3 A–D; trochanter with small retrolateral apophysis and ventral apophysis; femur with retrolateral apophysis; patella large; procursus simple proximally but complex distally ( Figs 3 View FIGURE 3 C–D); bulb simple, no other projections except for embolus. Retrolateral trichobothria of tibia I at 11% proximally; legs with short vertical setae on metatarsi and tarsi, without spines and curved setae; tarsus I with 10 distinct pseudosegments.
Female (IZCAS-Ar39654): Similar to male, habitus as in Figs 4 View FIGURE 4 G–H. Total length 2.30 (2.38 with clypeus), carapace 0.77 long, 0.89 wide, opisthosoma 1.53 long, 1.22 wide; tibia I: 3.64; tibia I L/d: 39. Distance PME-PME 0.11, diameter PME 0.11, distance PME-ALE 0.02. Sternum slightly wider than long (056/0.46). Epigynum ( Fig. 4A View FIGURE 4 ) brown. Vulva ( Fig. 4B View FIGURE 4 ) with slightly curved anterior arch and pair of triangular pore plates.
Natural History. The species was found on its irregular web in the entrance zone of cave.
Distribution. China (Guizhou, type locality; Fig. 17 View FIGURE 17 ).
