Type material. Holotype: male ( SMF), secondary forest, forest floor and foliage (10°29’25”N, 104°18’6”E, elevation 119 m), Phnom Kep, Kep, Kep, Cambodia, 11 July 2017, P. Jäger leg. Paratype: 1 male ( SMF), secondary forest, leaf litter (10°28’50”N, 104°17’50”E, elevation 128 m), Phnom Kep, Kep, Kep, Cambodia, 8 July 2017, P. Jäger leg.

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

Diagnosis. This species resembles K. diaoluoshanensis Tong & Li, 2008 (see Tong & Li 2008: 52, figs 1J–L, 5A–G) with similar male chelicerae ( Figs 4A, B ) but can be distinguished by the presence of a slender, laminar subdisto-prolateral apophysis (arrow 1 in Fig. 3C ) and a large, robust disto-retrolateral apophysis (arrow 2 in Fig. 3C ) on the procursus.

Description. Male (holotype): Total length 1.73 (1.85 with clypeus), carapace 0.71 long, 0.79 wide, opisthosoma 1.02 long, 0.78 wide. Leg I: 11.97 (3.27 + 0.29 + 3.21 + 3.85 + 1.35), leg II: 7.80 (2.24 + 0.27 + 1.99 + 2.50 + 0.80), leg III: 6.19 (1.79 + 0.25 + 1.47 + 2.05 + 0.63), leg IV: 7.94 (2.40 + 0.28 + 2.02 + 2.61 + 0.63); tibia I L/d: 32. Distance PME-PME 0.08, diameter PME 0.10, distance PME-ALE 0.03, AME absent. Sternum wider than long (0.56/0.44). Habitus as in Figs 4C–E . Carapace brownish, with dark margins and narrow, dark median line; ocular area and clypeus brown, with dark marks; sternum black. Legs brownish, but slightly whitish on distal parts of femora and tibiae, with darker rings on subdistal parts of femora and tibiae. Opisthosoma yellowish with black marks dorsally and laterally and wide black stripe ventrally. Ocular area slightly elevated and separated from rest of carapace. Thoracic furrow shallow but distinct. Chelicerae as in Figs 4A, B , with pair of strong proximo-lateral apophyses, pair of small, nearly transparent front-lateral apophyses (arrow in Fig. 4B ), pair of small distal apophyses on front-lateral surface, and pair of long, hooked frontal apophyses (distance between tips: 0.04). Pedipalps as in Figs 3A, B ; trochanter with short retrolateral apophysis and small ventral apophysis; femur with retrolateral apophysis; patella large; procursus simple proximally but complex distally, with slender, laminar subdisto-prolateral apophysis (arrow 1 in Fig. 3C ) and large, robust disto-retrolateral apophysis (arrow 2 in Fig. 3C ); bulb simple, no other projections except for embolus. Legs with short vertical setae on tibiae, metatarsi and tarsi, without spines and curved setae; tarsus I with 13 distinct pseudosegments.

Female: Unknown.

Variation: Tibia I in male paratype: 3.01.

Distribution. Cambodia (Kep, type locality; Fig. 11 ).
