Diagnosis. The male of newly described species is most similar to C. tsurui Ono, 2007 in the general shape of its palp, but can be easily distinguished by winding structure of embolus and broad tipped and twisted embolic apophysis.

Description. Male (holotype). Carapace: dark yellowish brown, oval, lustrous, several long setae at middle, longer than wide; head region flat, thoracic region with black marginal stripes slope gently; cervical furrow and radial furrow distinct, fovea indistinct, slightly depressed (Fig. 1A, B); clypeal outgrowth round, small warts with a short hair dorsally (Fig. 1 A-D). Eyes: ALE largest, interdistance between PME-PME farthest; PER slighly longer than AER; AER almost straight and PER recurved from front, AER recurved and PER almost straight from above. Chelicera: weak, dark yellowish brown; two promarginal teeth, lower tooth larger with small projection (Fig. 1E). Endite and labium: dark yellowish brown, endite wider than long (Fig. 1F). Sternum: dark yellowish brown, round, slightly convex, wider than long; covered densely with small warts bearing a short hair; not protrude between fourth coxae (Fig. 1F). Legs: short and thick, yellowish brown, semi-transparent, hairy without spines, no annuli; I≒ IV-II-III. Abdomen: grayish brown, globular, hairy, no particular pattern with two pairs of muscle impressions, longer than wide (Fig. 1A, B); venter grayish brown. Spinnerets: pale grayish brown, anterior spinnerets largest and posterior ones poorly developed; colulus small with a pair of setae (Fig. 1G). Male palp (Fig. H-J): tibia short and simple without spines and trichobothria; cymbium slender and semi-transparent with long transparent setae, distally modified with a finger-shaped process; embolus filate and winding with a twisted and broad tipped embolic apophysis (Fig. 1K).
