Etymology. The specific name is a patronym in honor of the collector Prof. Hao Yu (Guizhou Education University), and is a noun (name) in genitive case.

Diagnosis. This species resembles K. digitata Yao & Li, 2010 (see Yao & Li 2010: 5, Figs. 1 A–D, 2A–D, 3A–D, 4A–C) and K. qian Yao & Li, 2019 (see Yao et al. 2019: 348, Figs. 9–10) with similar male chelicerae (Figs. 6 C–D) but can be distinguished by procursus with thin sclerotized apophysis distally (arrow in Fig. 5C), by epigynum without posterior lip (Fig. 6A), and by vulval pore plates narrow anteriorly (Fig. 6B); also distinguished from K. digitata by vulval anterior sclerite relatively small laterally (arrow in Fig. 6B); also distinguished from K. qian by vulval pore plates wide posteriorly (Fig. 6B).

Description. Male (holotype): Total length 2.31 (2.46 with clypeus), carapace 0.82 long, 1.12 wide, opisthosoma 1.49 long, 1.18 wide. Leg I: 28.85 (7.24 + 0.46 + 6.94 + 10.97 + 3.24), leg II: 18.16 (4.94 + 0.45 + 4.28 + 6.81 + 1.68), leg III: 13.52 (4.07 + 0.41 + 3.16 + 4.79 + 1.09), leg IV: 16.49 (5.03 + 0.42 + 3.88 + 6.02 + 1.14); tibia I L/d: 53. Distance PME-PME 0.14, diameter PME 0.16, distance PME-ALE 0.04, AME absent. Habitus as in Figs. 6 E–F. Carapace yellowish, with black margins and dark median line; ocular area yellowish, with dark brown marks laterally; clypeus dark brown; sternum black. Legs brownish, but whitish on distal parts of femora and tibiae, with darker rings on subdistal parts of femora and proximal and subdistal parts of tibiae. Opisthosoma yellowish, with large black spots. Ocular area slightly elevated and separated from rest of carapace. Thoracic furrow shallow, but distinct. Sternum wider than long (0.70/0.57). Chelicerae (Figs. 6 C–D) with pair of proximo-lateral apophyses provided with scales each, pair of small distal apophyses laterally, pair of large frontal apophyses provided with scales each (arrows in Figs. 6 C–D), and pair of long and hooked frontal apophyses provided with scales each (tips close together). Pedipalps as in Figs. 5 A–B; trochanter with short retrolateral apophysis and small ventral apophysis; femur with retrolateral apophysis; patella large; procursus simple proximally but complex distally, with thin sclerotized apophysis distally (arrow in Fig. 5C) and long distal apophysis provided with scales; bulb simple, no other projections except for embolus. Retrolateral trichobothrium of tibia I at 6% proximally; legs with short vertical setae on tibiae, metatarsi and tarsi, without spines and curved setae; tarsus I with 11 distinct pseudosegments.

Female: Similar to male, habitus as in Figs. 6 G–H. Total length 2.47 (2.56 with clypeus), carapace 0.88 long, 1.09 wide, opisthosoma 1.59 long, 1.55 wide; tibia I: 5.82; tibia I L/d: 49. Distance PME-PME 0.16, diameter PME 0.14, distance PME-ALE 0.05, AME absent. Sternum wider than long (0.72/0.62). Epigynum (Fig. 6A) brown, without pockets. Vulva (Fig. 6B) with curved anterior arch and sclerite (arrow in Fig. 6B) and pair of nearly triangular pore plates.

Variation: Tibia I in male paratype: 6.38, in the male from Daheba: 6.28. Tibia I in the female from Daheba (n=1, leg I missing in the other two specimens): 6.02.
