[ Porthesia kurosawai: Chao 2003: 317 .] Misidentification

Diagnosis. Forewing length 12–17 mm. Forewing reddish brown with a yellow irregular border in male, and a yellow patch at apex, central termen and dorsum respectively in female. Male genitalia ( Fig. 29 ): Uncus broad, weakly bifid. valva divided in the distal half, the dorsal arm broad, the ventral arm slender, acute apically; saccus triangular; aedeagus simple, vesica unadorned. Female genitalia ( Fig. 43 ): Papilla analis small; ductus short, cylindrical, sclerotized; bursa long, sausage-shaped, with a bicornute signum.

Material examined. 33, Nanling National Nature Reserve, Guangdong, 6.V.2006; 1Ƥ, same locality, 31.IV.2008.

Distribution. China (Hebei, Jiangsu, Anhui, Zhejiang, Hubei, Sichuan, Fujian, Hunan, Guangdong, Guangxi, Hainan, Taiwan), Korea, Japan, Nepal, India, Sri Lanka.

Remarks. Strand (1933) regarded the species as typical of Porthesia Stephens. However , Porthesia has been confirmed by Maes (1984) as an invalid genus. P. k u ro s a w a i Inoue reported by Chao (2003) from Guangxi Province in China is actually Somena scintillans , based on the adults and male genitalia.
