Diagnosis. The forewing length is 16.0–20.0 mm in males and 18.0–20.0 mm in females. Collitoptyx fraterna sp. n. is externally very similar to C. incurvata and differs only in the somewhat larger costal spot of the forewing. In the male genitalia, the new species is distinguished from its island sister species by the longer uncus, the markedly shorter and narrower conical dorsal section of the juxta, the somewhat longer ventral lateral protrusions of the vinculum, the somewhat longer distal saccular process, and the considerably larger, spike-like cornutus in the vesica, which is tiny and conical in C. incurvata . The male genitalia of C. fraterna sp. n. differ from C. incurvata in the longer posterior section of the corpus bursae with a longer ventro-lateral sclerotised protrusion.

Distribution. The new species is known from northern Mainland Southeast Asia (Northern Vietnam, Northern Laos and Northern Thailand), and mainland China (provinces of Yunnan, Sichuan, Shaanxi, Fujian, and Jiangxi). The male genitalia from China illustrated by Daniel (1954) as ‘ Lithosia tetragona ’, and Fang (2000) as ‘ Thysanoptyx tetragona ’ belong to C. fraterna sp. n.

Etymology. The specific epithet is a Latin adjective meaning ‘brotherly’ and referring to the close relationship of the new species to the allopatric C. incurvata .
