Male genitalia. Pygofer (Fig. 17) with posteroventral margin obtusely emarginate, apex acutely angulate in lateral view. Anal tube processes moderately slender and nearly straight, extended 2/3 distance to pygofer apex. Subgenital plate (Fig. 17) narrow and elongate, with long fine setae on apical margin. Connective (Fig. 18) Yshaped, with long stem. Style (Fig. 19) curved dorsally with acute indentation just distad of lateral lobe, with few short apical setae in lateral view. Aedeagus shaft (Figs. 20, 21) straight for most of length in lateral view, expanded distally in posterior view with laterall lamella finely dentate, apex acute in lateral and posterior view, with one pair of slender lateral preapical processes extended ventrolaterad to basal half of shaft.
Measurements (mm). Male: body length 5.0–5.2, face length 1.1–1.2, width 1.3–1.4; distance between ocelli 0.70–0.80; distance fromcellus to eyes 0.20–0.30; medial length of pronotum 0.50–0.55, width 0.80–0.85; scutellum length 0.80–0.85, width 0.70–0.75.
Type material. Holotype, ♂, Xinping County, Mt. Ailao, Yunnan Province, China (101° 30′ 34″ E, 23° 58′ 06″ N; H: 2071 m), 4–5 June 2019, coll. Xianyi Wang & Qin Zuo. Paratypes, 2♂♂, Pingbian County, Mt. Daweishan, Yunnan Province, China. (101° 41′ 18″ E, 22° 59′ 12″ N; H: 1500 m), 14–16 June 2019, coll.

Remarks. The new species is similar to C. shii, but it can be distinguished from the latter by the serrate lateral margins and single pair of elongate lateral processes of the aedeagus.
Etymology. The new species name is derived from the words “ dent- ” and “ aedeagus ”, referring to the aedeagus subapex with dentate lamellar.
Distribution. China (Yunnan province). (Fig. 22).
