( Figs. 3 , 6 , 9 )

Ethmia pingxiangensis Liu, 1980: 276 . Type locality: Guangxi, China.

Ethmia amissus Kun, 2001: 210 , syn. nov. Type locality: Saraburi, Thailand.

Material examined. Holotype: Ƥ, China: Pingxiang City (22°6' N, 106°45'E), Guangxi Zhuang Autonomous Region, 11.vi.1976, genitalia slide No. 74063 ( IZCAS).

Additional material. 63, 1Ƥ, Jingxi County, Bangliang, Guangxi Zhuang Autonomous Region, 31.vii −5.viii.2010, coll. Jianhua Huang; 13, Liusanjie Town, Yizhou City, Guangxi Zhuang Autonomous Region, 169 m, 19.viii.2011, coll. Shulian Hao and Yinghui Sun; 13, Pingxin Town, Yizhou City, Guangxi Zhuang Autonomous Region, 150 m, 16.viii.2011, coll. Shulian Hao and Yinghui Sun, genitalia slide Nos. WJJ 100403, WJJ10074Ƥ, WJJ 110123 (NKU).

Male genitalia. ( Fig. 6 ). Uncus 2/3 as long as tegumen, narrowed at base, widened gradually to middle; distal half stout, extending obliquely to both sides in V shape, blunt at apex. Gnathos with caudal part trilobed: middle lobe rectangular, apically dentate and concave triangularly at middle; lateral lobes stubbed and broad, shorter than middle lobe, with fine thorns on posterior margin, bluntly rounded apically; oral part membranous, ventrally connected with caudal part by a semi-rounded process, concave anteriorly at middle. Labis about 2/5 length of uncus, more or less hammer-shaped, apex blunt. Valva with costa weakly sclerotized, arched dorsally, slightly protruded dorsoapically; sacculus broad, ventral margin obliquely straight; cucullus irregularly shaped, about half length of sacculus, bluntly rounded at apex, with a thin spine at middle on dorsal margin bearing a row of long setae on inner margin, with a strong spine at end of ventral margin, with a cluster of long thick subventral spines on dorsal surface apically exceeding apex of valva. Transtilla narrow-banded. Aedeagus tubular, with a heavily sclerotized ring distally, vesica sclerotized; cornutus needle-like.

Diagnosis. This species can easily be separated from its congeners by the forewing having a tadpole-shaped marking on distal 1/3 of cell.

Distrbution. China (Guangxi); Burma, Thailand, India (Sikkim).

Remarks. Liu (1980) described E. pingxiangensis based on one female specimen collected from Guangxi, with illustration of genitalia. After checking the holotype, we found that the adult and genitalia of E. amissus Kun, 2001 , recorded from Thailand, Burma and India are identical to those of E. pingxiangensis . We herein synonymize E. amissus with E. pingxiangensis , and describe the male of this species for the first time.
