Etymology. The specific epithet is a noun in apposition referring to the type locality.

Diagnosis. The new species resembles C. denjii sp. nov. in body pattern and shape of genitalia, but the male can be distinguished from C. denjii sp. nov. by the absence of small denticles on the embolus and the unbranched RTA (Figs 113–117); the female can be distinguished by the different CD path (Figs 120, 122).

Measurements of legs: I 3.18 (1.00, 0.54, 0.74, 0.52, 0.38), II 2.85 (0.93, 0.42, 0.67, 0.50, 0.35), III 3.36 (1.07, 0.51, 0.59, 0.74, 0.45), IV 3.84 (1.11, 0.55, 0.82, 0.89, 0.47).

Sternum without setal tuft. Color in alcohol (Figs 107–108): carapace dark brown, CPSB frontally white; dorsal abdomen slightly sclerotized, yellowish brown with dark brown markings; ventral abdomen with a large black marking; tibiae I–II, metatarsi I–II and tarsi I–II darker than other leg segments.
