Etymology.
The specific name derived from the name of the
type
locality.
Diagnosis.
This species resembles
K. dongkou
Yao & Li, 2010
and
K. miaoshanensis
Yao & Li,
2010
in having similar male chelicerae (
Fig. 3
C) and a similar epigynum (
Figs 2
A and 3D), but can be distinguished by different distal elements of procursus, longer than those of
sancai
n. sp.
, (
Figs 1
A–B, D, 3A–B) and nearly rectangular lateral pore plates of the vulva (
Figs 2
A–B, 3D–E).
Description. Male (
holotype
):
Total length 2.03 (2.26 with clypeus), prosoma length 0.73, width 0.85; opisthosoma length 1.30, width 0.82. Leg I: 18.59 (4.69 + 0.44 + 4.72 + 6.48 + 2.26), leg II: 13.18 (3.78 + 0.42 + 3.14 + 4.49 + 1.35), leg III: 9.93 (2.95 + 0.38 + 2.31 + 3.33 + 0.96), leg IV: 12.71 (3.72 + 0.41 + 3.08 + 4.47 + 1.03); tibia I L/d: 46. Habitus as in
Fig 1
C. Dorsal shield of prosoma yellowish, with black margins and a median black stripe behind ocular area; sternum black. Legs yellowish. Opisthosoma grey, without large black spots. Distance PME–PME 0.08, diameter PME 0.12, distance PME–ALE 0.015, AME absent. Ocular area slightly elevated and separated from Prosoma. Thoracic furrow shallow but distinct. Sternum slightly wider than long. Chelicerae as in
Fig 3
C, with a pair of hook-shaped frontal apophyses (tips widely separated from each other), two pairs of thumb-shaped proximolateral apophyses (tips widely separated from each other) and a pair of small thumbshaped distal apophyses on anterolateral surface. Pedipalpi as in
Figs 1
A–B and 3A–B; trochanter with a retrolateral apophysis and a small ventral apophysis; femur with a retrolateral apophysis; patella large; procursus simple proximally but complex distally, and its distal part longer than the bulb, distinctly longitudinally depressed and with a sharp anterior an d distal projections; bulb simple, no other projections except for embolus. Tarsus I with more than 30 pseudosegments, of which the distal 15 pseudosegments are distinct.
Variation.
Tibia I length in other males (n=2): 3.80–4.83 (mean: 4.40).
Female.
Similar to male, habitus as in
Figs 2
C–D. Leg I lost in all female specimens. Epigynum brown (
Figs 2
A and 3D), without distinct pockets. Vulva (
Figs 2
B and 3E) with two nearly rectangular lateral pore plates.
Distribution.
The species is known only from the
type
locality (
Fig. 7
).
