Psyra cuneata dsagara Wehrli, 1953 , in Seitz, Gross-Schmett. Erde, 4 (Suppl.): 671. Lectotype 3, China: Tibet (north-east): Dsagar Mountain (ZFMK), herein designated.

Material examined. CHINA: Sichuan ( ZFMK): 13 (Lectotype, Here designated), Tibet, Tschang-Tang Dsagar- Berge, 4500 m, VI. Sichuan ( IZCAS): 13, Luding, Xinxing, 1920 m, 13.VI.1983, coll. Zhang Xuezhong; 13, Emei Shan, 15.VIII.1977 (slide no. Geom-2031); 1Ƥ, Pingwu, Laohegou, 1630 m, 16.VIII.1999, coll. Zhou Xin; Hunan ( IZCAS): 131Ƥ, Tianping Shan, 1–7.VI.1981 (slide no. Geom-2026, 2060); Yunnan ( IZCAS): 13, Zhenxiong, 1750 m, 20.VI.1980, coll. Zheng Jiahua (slide no. Geom-2025); 13, Dali, Zhonghefeng, 2600 m, 3.IX.1980 (slide no. Geom-1995).

Diagnosis. Compared to P. cuneata and P. szetschwana , P. dsagara has smaller antemedial patches, lacks a distinct hindwing medial band, but has a more complete hindwing terminal band. The male genitalia are distinctive in the up-curved, blunt and swollen apex of the valva, and in lacking the tiny pointed process on the tip of the costal basal lobe; although P. spurcataria and P. crypta also lack the tiny pointed process, they do not have the swollen valva apex. Compared to P. c u n e a t a, the female genitalia have a much broader ductus bursae and a larger corpus bursae.

Distribution. China (Sichuan, Hunan, Yunnan).

Remarks. P. szetschwana and P. dsagara were treated as synonyms of P. cuneata in Parsons et al. (1999), but no related synonymic history has been found. The male genitalia of the only dissected syntype of P. cuneata dsagara are totally different from those of P. c u n e a t a, we therefore upgrade dsagara to specific level.
