Hendecaneura Walsingham, 1900

Hendecaneura Walsingham, 1900 , The Annals and Magazine of Natural History, (7)6: 401.

Type species: Hendecaneura impar Walsingham, 1900 .

Eucosmodes Kuznetzov, 1973 , Entomologicheskoe Obozrenie, 52: 689.

Type species: Eucosma axiotima Meyrick, 1937 .

Venation. Forewing with all veins separate, chorda and M-stem missing; R 4 to costa, R 5 to termen; M 2 close to M 3; CuA 1 bent forward; CuP rudimentary. In male of the type species, Sc vein absent. Hindwing with Rs and M 1 stalked at basal 1/3; M 3 and CuA 1 short stalked; CuP rudimentary. Male forewing with costal fold, sometimes undeveloped and on the upper surface often with a circular pocket covered with broad scales near the junction of 1A and 2A veins.

Male genitalia. Tegumen broad. Uncus mound-like, triangular or trapeziform; socius drooping, round apically, hairy. Neck of valva distinct; sacculus sometimes dilated towards its end, often with a lobe on the ventral edge of basal opening, sacculus angle rounded or right-angled; cucullus varied in shape, oblong, triangular or boot-shaped etc.

Female genitalia. 7th sternite partially or entirely fused with sterigma; ductus bursae with postmedian cingulum; ductus seminalis originating ventrally from cingulum. Corpus bursae with two signa present except H. rhododendrophaga Nasu & Komai with only one large funnel-shaped signum.

Remarks. Hendecaneura Walsingham is similar to Lepteucosma Diakonoff , but can be distinguished by presence of a circular pocket covered with broad scales at base of 1A+2A vein in male forewing, absence of anal fold in male hindwing, mound-like, triangular or trapeziform uncus and the fusion of the 7th sternite and the sterigma. While in Lepteucosma a circular pocket at base of 1A+2A vein in male forewing is absent, anal fold in male hindwing is present, uncus is bifurcated and the 7th sternite is separated from the sterigma. Nasu (1996) and Nasu & Komai (1997) described the circular pocket at base of 1A+2A vein in male forewing in detail, which is an important character of male forewing. During my study on the species of Hendecaneura , the circular pocket at base of 1A+2A vein is absent in male forewing of some species, such as H. tricostatum and three species in this paper. With more species of Hendecaneura found, the characters of the genus Hendecaneura will be revised.
