Type materials. Holotype: ♂ from Jangheung-ri , Jangheung-eup , Cheorwon-gun, Gangwon-do, Korea (127°15 ʹ 30.5 ʺ E, 38°11 ʹ 59.8 ʺ N), 20 May 2017, S. T. Kim and S.Y. Lee GoogleMaps . Paratype: 2♂♂, same data as holotype GoogleMaps ; 1♂, same data as holotype GoogleMaps , 30 May 2017, S. T. Kim and S.Y. Lee .

Etymology. The specific epithet is a noun in apposition derived from the Korea where the types were collected.

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.

Eye; ALE 0.04, AME 0.02, PLE 0.03, PME 0.03; AME-AME 0.02, AME-ALE 0.03, AME-PME 0.03, PME-PME 0.06, PME-PLE 0.03, ALE-PLE contiguous; AER 0.22, PER 0.23. Chelicera 0.19 long, 0.09 wide. Endite 0.08 long, 0.14 wide. Labium 0.05 long, 0.04 wide. Sternum 0.27 long, 0.30 wide. Legs; I, 1.05 (0.32, 0.36, 0.20, 0.17); II, 0.96 (0.32, 0.32, 0.14, 0.18); III, 0.79 (0.24, 0.26, 0.12, 0.17); IV, 1.04 (0.31, 0.37, 0.16, 0.20). Abdomen 0.60 long, 0.52 wide.

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 View Fig ); clypeal outgrowth round, small warts with a short hair dorsally ( Fig. 1 View Fig 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 View Fig ). Endite and labium: dark yellowish brown, endite wider than long ( Fig. 1F View Fig ). 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 View Fig ). 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 View Fig ); venter grayish brown. Spinnerets: pale grayish brown, anterior spinnerets largest and posterior ones poorly developed; colulus small with a pair of setae ( Fig. 1G View Fig ). 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 View Fig ).

Ecological remarks. Present species was collected by pitfall traps at levees around traditional rice ecosystem.
