Female. Unknown.

Material examined. Holotype male. KOREA: Seoul, Noweon-gu, Sanggye-dong, Mt. Suraksan, 37°41'N 127°04'E, 230 m a.s.l., 15–21.viii.2009, leg. J. Lim.

Paratypes. KOREA: Gyeunggi-do, Suwon-si, Gwonseon-gu, Seodun-dong, Mt. Yeogi, Malaise trap, 8.v.1995, leg. J. Choi (1♂); 4.ix.1995, leg. J. Choi (2♂).

Habitat. Unknown.

Distribution. Only known from Korea.

Remarks. This species is similar to C. (s. str.) freemani Menzel & Mohrig, 2000 in the shape of the maxillary palpus and genitalia. However, the new species is easily distinguished by the medial inner side of gonostylus possessing distinctly separated lobes, with a pair of spines on each lobe (Fig. 3 B, 4).

Etymology. - ensis (Latin) = a suffix denoting place, locality or country. This species is named after the locality where the species was first collected, Suwon-city.
