Psyra gracilis Yazaki, 1992 , in Haruta, Tinea , 13 (Suppl. 2): 35, pl. 11, figs 8, text-fig. 31. Holotype 3, Nepal: Godavari (NSMT).

Material examined. CHINA: Yunnan ( IZCAS): 13, Luxi, Huataolin, 1200 m, 4.V.1980, coll. Li Hongxing (slide no. Geom-2024).

Diagnosis. On wing pattern, P. gracilis has a distinctive lunar antemedial patch on the inner margin. The holotype ( Fig. 8 in Yazaki 1992, in somewhat poor condition as stated by Yazaki) of P. gracilis is close to P. fulvaria ( India and Nepal), in having less black patches on the forewing. The only specimen in IZCAS, from Yunnan, has much larger black patches, and the wedge-shaped patch is much broader than in the holotype. The male genitalia are distinctive in having a triangular valva, which bears a small rounded process and a serrate sclerite near the ventral margin; the shape of the uncus is identical to that of P. cuneata ; the aedeagus has three bundles of spines as in P. cuneata and P. spurcataria , but the spines are longer. The female genitalia are unknown.

Distribution. China (Yunnan), Nepal; newly recorded here for China.
