Ethmia guangzhouensis Liu, 1980 (Figs. 2, 5, 8) Ethmia guangzhouensis Liu, 1980: 274. Type locality: Guangdong, China. Ethmia pseudozygospila Kun & Szabóky, 2000: 71, syn. nov. Type locality: Taiwan, China. Material examined. Paratypes: 3 3, 2 ƤƤ, China: Botanical Garden (23°9' N, 113°20' E), Guangzhou City, Guangdong Province, 23.vi.1978, genitalia slide Nos. 781053/106Ƥ/1093 (IZCAS). Additional material. Taiwan: 1 3, Ping Tung Co. Kenting Bot. Garden, subtropical forest, 260 m, 22−25.vii.1980, coll. D. R. Davis; 1Ƥ, Kao Hsiung Co., 10−11 km NE Chiahsien, ca. forest, 300 m, 03−08. vii.1980, coll. D. R. Davis, genitalia slide Nos. WJJ 101333, WJJ10134Ƥ (NMNH). Diagnosis. This species is similar externally to E. zygospila Meyrick, 1934, but can be distinguished by the forewing having one indistinctly marked V-shaped pattern, while in the latter species, the forewing has two Vshaped patterns longitudinally. It is close to E. damaoshanae Wang & Zheng, 1997 in the male genitalia, but can be recognizd by the cucullus having a blunt dorsoventral tip, while the cucullus of E. damaoshanae has a pointed dorsoventral tip. Distribution. China (Guangzhou, Taiwan). Remarks. Liu (1980) described E. guangzhouensis based on five male and four female specimens collected from Guangzhou, with illustrations of male and female genitalia. After checking three male and two female paratypes, we found that the forewing patterns and the genitalia of E. pseudozygospila Kun & Szabóky, 2000, known from Taiwan are identical to those of E. guangzhouensis Liu. So we regard E. pseudozygospila Kun & Szabóky, 2000 as a synonym of E. guangzhouensis Liu.
