Type material. Holotype: Male, Pleasant Fall Area (16°13.763′N, 107°50.891′E, elevation 371 m), Bach Ma National Park, Thua Thien-Hue, Vietnam, 27 August 2015, Q. Zhao, Y. Li and Z. Chen leg. Paratypes: 2 males and 3 females, same data as holotype.
Etymology. The specific name refers to the type locality, and is a noun in apposition.
Diagnosis. This species resembles K. dangi Yao, Pham & Li, 2015 (see Yao et al. 2015: 12, figs 35A–D, 36A– E, 37A–D) with similar male chelicerae (Figs 2C–D) but can be distinguished by narrow median line on carapace (Fig. 2E) and by presence of two sclerites distally on procursus (arrows 1 and 2 in Fig. 1C). This species also resembles K. quangbinh Yao & Li sp. nov. (Figs 9–10) with similar male chelicerae (Figs 2C–D) and female genitalia (Figs 2A–B) but can be distinguished by large, nearly angular prolateral sclerite (arrow 1 in Fig. 1C) and nearly square retrolateral sclerite (arrow 2 in Fig. 1C) on procursus.
Description. Male (holotype): Total length 2.57 (2.74 with clypeus), carapace 0.80 long, 0.83 wide, opisthosoma 1.77 long, 1.10 wide. Leg I: 28.99 (7.05 + 0.43 + 6.93 + 11.45 + 3.13), leg II: 17.36 (4.82 + 0.42 + 4.15 + 6.58 + 1.39), leg III: 12.81 (3.83 + 0.35 + 2.95 + 4.55 + 1.13), leg IV: 16.85 (5.10 + 0.38 + 3.95 + 6.38 + 1.04); tibia I L/d: 62. Habitus as in Figs 2E–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 tibiae. Opisthosoma yellowish, with large black spots. Distance PME-PME 0.14, 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 (0.67/0.60). Chelicerae (Figs 2C–D) with pair of small proximo-lateral apophyses, pair of small distal apophyses on front-lateral surface, pair of strong frontal apophyses (arrows in Figs 2C–D) provided with scales each, and pair of long, hooked frontal apophyses (distance between tips: 0.03). Pedipalps as in Figs 1A–D; trochanter with short retrolateral apophysis and small ventral apophysis; femur with retrolateral apophysis; patella large; procursus simple proximally but complex distally, with nearly angular prolateral sclerite and nearly square retrolateral sclerite (arrows 1 and 2 in Fig. 1C); bulb simple, no other projections except for embolus. Retrolateral trichobothria of tibia I at 9% proximally; legs with short vertical setae on tibiae, metatarsi and tarsi, without spines and curved setae; tarsus I with 10 distinct pseudosegments.
Female: Similar to male, habitus as in Figs 2G–H. Total length 2.48 (2.64 with clypeus), carapace 0.74 long, 0.92 wide, opisthosoma 1.74 long, 1.08 wide; tibia I: 6.12; tibia I L/d: 61. Distance PME-PME 0.12, diameter PME 0.11, distance PME-ALE 0.02, AME absent. Sternum slightly wider than long (0.60/0.56). Epigynum (Fig. 2A) yellowish, without pockets. Vulva (Fig. 2B) with slightly curved anterior arch and pair of large, nearly triangular pore plates.
Variation: Tibia I in male paratypes (n = 2): 7.08, 7.50. Tibia I in the other female paratypes (n = 2): 6.58, 6.98.
Natural History. The species was found on its irregular web between rocks.
Distribution. Vietnam (Thua Thien-Hue, type locality; Fig. 11).
