Diagnosis. The species is different by the forewing of male has the upper edge of cell diffused with fuscous long setae at basal half and androconial hairs covered with apical 1/3 of the cell from the upper edge. In male genitalia, it is characteristic by the three strong specialized setae about 3/5 length of valva, and the third seta with minute spines laterally and a knifeshaped apex. In female genitalia, it can be distinguished by its signa about 5/6 length of corpus and the shape of signa.

Male genitalia ( Fig. 12 ). Uncus slender; gnathos about 4/5 length of uncus, apex with several dorsal teeth; tegumen with sclerotized dorsal ridge X-shaped; valva densely covered with setae, slightly constristed in base and apex, three strong specialized setae present at apex, about 3/5 length of valva, third seta with minute spines laterally and a knife-shaped apex; vinculum broad; saccus round; juxta plate-like, with apex bifid; aedeagus slender, vesica with many minute spines, ductus ejaculatorius arising from middle.

Female genitalia ( Fig. 13 ). Anal papillae relatively broad, densely covered with setae; apophysis anterioris and posterioris near same length; antrum elongated, cylindric; collar sclerotized; ductus seminalis arising below collar; ductus bursae about 1/3 length of corpus bursae, with many minute spines; a pair of singa present, about 5/6 length of corpus, consisting of many minute spines, and with base and apex constricted.

All deposited in IZCAS.

Distribution. China (Heilongjiang (?), Zhejiang, Hubei, Jiangxi, Hunan, Guangdong, Hainan, Guangxi, Sichuan, Yunnan, Xizang), Vietnam, India, Nepal, Afghanistan, Ethiopia.

Remarks. The specimens examined were mostly from South China, except a female from Heilongjiang Province (Dailing). The discontinuous distribution is hard to explained. We doubt the specimens from Heilongjiang was mislabeled. So the distribution of Heilongjiang is in doubt.

In China, the species was misidentified as E. peribocalis ( Walker, 1859) pastly. Caradja ( Caradja, 1925; Caradja & Meyrick, 1934) reported the distribution of this specis in Jiangxi, Fujian and Guangdong Provinces in China. Speidel (1984) rechecked the materials collected by Caradja between 1925–1938, and proposed those materials are the misidentification of E. halialis . By examing all materials from IZCAS and part materials from NKU, we agreed the point that the past “ E. peribocalis ” in China should really be E. halialis . The “ E. peribocalis ” from Song (1993, 2001, 2002) should be E. halialis . The “ E. peribocalis ” from Li, You & Wang (2003) should be the mixture of E. halialis and E. menglensis . The real E. peribocalis is not distributed in China.
