Type materials.

Holotype: China • ♂; Xizang Autonomous Region, Linzhi City , Medog County; alt. 2400 m; 1 Nov. 2023; Chuhang Qiao & Ziqi Yuan & Liang Guo leg. Paratype: • 1 ♂; same collection data as for preceding .

Diagnosis.

The new species is similar to C. glaucinoptera ( Collenette, 1934) , comb. nov. in male, but can be distinguished from the latter by the hindwings light brown, uncus slightly pointed, valvae with a weak and indistinct saccular process. It also resembles C. dudgeoni comb. nov. in male, but the latter has dark brown wings and longer valvae. The new species differs from C. flavimacula comb. nov. by forewings without a yellow-white crescent spot near anal angle, and gnathus bifurcating into two slenderer forks.

Abdomen light brown. Forewings ground color greyish-brown, with two dark brown or yellowish-brown basal spots in which the ventral one is nearly ring-like; a large, faint yellow crescent spot present along the outer margin of discal cell slanting to costa; antemedian line blurred, dark brown; postmedian fascia wavy; and cilia of outer margin dark brown. Hindwings light brown, without markings; cilia of outer margin dark brown.

Male genitalia (Fig. 4 A ). Uncus short, digitate. Gnathus well developed, bifid, each fork crescent-shaped. Valvae broad at basal half, narrowed at distal half. Juxta well sclerotized at dorsal margin. Saccus small. Aedeagus simple, slightly curved distally.
