Diagnosis. The forewing length is 15.0–15.5 mm in males. Parabitecta yanmena sp. n. is externally similar to P. baoshana sp. n. but can be distinguished by the somewhat more convex costal and anal margins of the forewing, the paler, ochreous brown body and forewing ground colour (vs. greyish-brown in the congener), the more distinct, broader and nearly straight medial transverse line having irregularly sinuous margins (it is angled in P. baoshana sp. n.), the paler subbasal androconial patch on the forewing upperside, and the darker, ochreous hindwing. In the male genital capsule, the new species differs from P. baoshana sp. n. in the narrower apex of the valva extended into a small process, the narrower but more swollen lamella centralis, and the thinner and less upcurved distal saccular process. The phallus of P. yanmena sp. n. is markedly shorter and distally broader than in P. baoshana sp. n., has a broader coecum and lacks the dorsal carinal process. Compared to P. baoshana sp. n., the vesica of the new species is considerably broader and medially dilated (whereas it is rather tubular in the congener), has an additional, bilobate distal diverticulum, and bears a shorter, medially angled and apically thinner and more pointed cornutus, which is displaced laterally.

The female is unknown.

Distribution. The new species is currently known only from its type locality in north-western Yunnan Province, Southwestern China.

Etymology. The specific epithet is derived from the town of Yanmenxiang, near which the new species was collected. The name is a noun in the nominative singular in apposition.
