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.
