Type material. Holotype: Male, Botanic Garden (17°33.15′N, 106°18.083′E, elevation 117 m), Phong Nha-ke Bang National Park, Quang Binh, Vietnam, 14 May 2016, Q. Zhao 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 10C–D) but can be distinguished by narrow median line on carapace (Fig. 10E) and by presence of two sclerites distally on procursus (arrows 1 and 2 in Fig. 9C). This species also resembles K. bachma Yao & Li sp. nov. (Figs 1–2) with similar male chelicerae (Figs 10C–D) and female genitalia (Figs 10A–B) but can be distinguished by small, narrow prolateral sclerite (arrow 1 in Fig. 9C) and nearly semicircular retrolateral sclerite (arrow 2 in Fig. 9C) on procursus.
Description. Male (holotype): Total length 3.05 (3.24 with clypeus), carapace 1.10 long, 1.14 wide, opisthosoma 1.95 long, 1.28 wide. Leg I: 30.51 (7.25 + 0.50 + 7.44 + 11.99 + 3.33), leg II: 19.20 (5.33 + 0.47 + 4.58 + 7.00 + 1.82), leg III: 14.38 (4.30 + 0.41 + 3.35 + 5.13 + 1.19), leg IV: 18.27 (5.38 + 0.43 + 4.38 + 7.10 + 0.98); tibia I L/d: 55. Habitus as in Figs 10E–F. Carapace yellowish, with brown 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 0.04, AME absent. Ocular area slightly elevated and separated from rest of carapace. Thoracic furrow shallow, but distinct. Clypeus unmodified. Sternum slightly wider than long (0.80/0.76). Chelicerae (Figs 10C–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 10C–D) provided with scales each, and pair of long, hooked frontal apophyses (distance between tips: 0.04). Pedipalps as in Figs 9A–D; trochanter with short retrolateral apophysis and small ventral apophysis; femur with retrolateral apophysis; patella large; procursus simple proximally but complex distally, with small, narrow prolateral sclerite and nearly semicircular retrolateral sclerite (arrows 1 and 2 in Fig. 9C); 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 9 distinct pseudosegments.
Female: Similar to male, habitus as in Figs 10G–H. Total length 3.06 (3.16 with clypeus), carapace 0.75 long, 0.85 wide, opisthosoma 2.31 long, 1.60 wide; leg I missing. Distance PME-PME 0.12, diameter PME 0.12, distance PME-ALE 0.04, AME absent. Sternum slightly wider than long (0.64/0.60). Epigynum (Fig. 10A) yellowish, without pockets. Vulva (Fig. 10B) with slightly curved anterior arch and pair of large, nearly triangular pore plates.
Variation: Tibia I in one male paratype (leg I missing in another specimen): 7.20. Tibia I in the other female paratypes (n = 2): 6.43, 6.68.
Natural History. The species was found on its irregular web between rocks.
Distribution. Vietnam (Quang Binh, type locality; Fig. 11).
