Type material. Holotype: Male (IZCAS-Ar39669), Shibaluohan Cave (22°32.433′N, 108°03.635′E, elevation 142 ± 3 m), Mu Village, Suwei Town, Nanning, Guangxi, China, 13 December 2017, Z. Chen leg. Paratypes: 2 females (IZCAS-Ar39670–Ar39671), same data as holotype.

Etymology. The specific name refers to the type locality and is a noun in apposition.

Diagnosis. This species resembles K. nanningensis Yao & Li, 2010 (see Yao & Li 2010: 12, f. 37A–D, 38A–D, 39A–D, 40A–D) with similar procursus (Figs 11 C–D), but can be distinguished by strong frontal apophyses medially on male chelicerae (Figs 12 C–D), absence of posterior lip on epigynum (Fig. 12A) and elliptic pore plates (Fig. 12B).

Description. Male (holotype): Total length 1.76 (1.82 with clypeus), carapace 0.70 long, 0.81 wide, opisthosoma 1.06 long, 0.82 wide. Leg I: 17.01 (4.09 + 0.36 + 4.31 + 6.22 + 2.03), leg II: 11.03 (3.09 + 0.33 + 2.70 + 3.84 + 1.07), leg III: 8.04 (2.26 + 0.31 + 1.94 + 2.76 + 0.77), leg IV: 10.51 (3.09 + 0.32 + 2.56 + 3.78 + 0.76); tibia I L/d: 48. Habitus as in Figs 12 E–F. Carapace yellowish, with black margins and narrow, dark median line; 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 0.10, 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 (0.45/0.44). Chelicerae (Figs 12 C–D) with pair of small proximo-ectal apophyses, pair of small distal apophyses on ectal surface, pair of strong frontal apophyses (arrows in Figs 12 C–D) provided with scales each, and pair of long, hooked frontal apophyses (distance between tips: 0.01) provided with scales each. Pedipalps as in Figs 11 A–D; trochanter with short retrolateral apophysis and ventral apophysis; femur with retrolateral apophysis; patella large; procursus simple proximally but complex distally (Figs 11 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 15 distinct pseudosegments.

Female (IZCAS-Ar39670): Similar to male, habitus as in Figs 12 G–H. Total length 1.90 (1.98 with clypeus), carapace 0.68 long, 0.75 wide, opisthosoma 1.22 long, 1.06 wide; tibia I: 4.08; tibia I L/d: 46. Distance PME-PME 0.12, diameter PME 0.10, distance PME-ALE 0.02. Sternum slightly wider than long (0.52/0.43). Epigynum (Fig. 12A) brown. Vulva (Fig. 12B) with curved anterior arch and pair of large nearly elliptic pore plates.

Variation: Tibia I in another female paratype (IZCAS-Ar39671): 4.44.

Natural History. The species was found on its irregular web in the entrance zone of cave.

Distribution. China (Guangxi, type locality; Fig. 17).
