Genus Eupoecilia Stephens, 1829

Eupoecilia Stephens, 1829: 190 ; Razowski, 1968: 103; Razowski, 1987: 166. Type species: Tortrix angustana Hübner, 1799 .

Clysia Hübner, 1825: 409 . Type species: Tinea ambiguella Hübner, 1796 . [preoccupied]

Eupecilia Herrich-Schäffer, 1851: 179 . [misspelling of Eupoecilia ]

Arachniotes Diakonoff, 1952: 24. Type species: Arachniotes dactylota Diakonoff, 1952 .

Diagnosis. Eupoecilia is characterized by the unique socii; the forewing with a distinct median fascia; the hindwing with R S and M1 stalked to about middle; and M3 and CuA1 variably stalked from 1/3 to 1/6. In the male genitalia, the socii have a broad base and a slender distal part, usually extending anteriorly; the sacculus sometimes has ventral spines or a prominence distally; the transtilla has a well developed central part armed with minute distal spines; and the aedeagus often has numerous cornuti of various size. In the female genitalia, the ductus bursae bears thorns and has a wrinkled surface, and the corpus bursae has sclerites bearing longitudinal folds accompanied by groups of spines.

Eupoecilia is similar to Eugnosta Hübner, 1825 in the possession of a broad coecum penis in the male genitalia, but it can be distinguished from the latter by the socius having a broad base and a slender distal part extending anteriorly, and the tegumen slightly to acutely narrowed dorsally. In Eugnosta the socii are rodlike, erect, and directed posteriorly, and the tegumen is broad with an obtuse dorsum.

Biology. The larvae of Eupoecilia feed on the leaves, flowers, and seeds of various plants. Documented host plants include Acer campestris (Aceraceae) , Achillea sp. ( Asteraceae ), Cornus mascula (Cornaceae) , Gnaphalium sp. ( Asteraceae ), Hedera helix (Araliaceae) , Ligustrum sp. ( Oleaceae ), Lonicera racemosa (Caprifoliaceae) , Plantago sp. ( Plantaginaceae ), Prunus sp. ( Rosaceae ), Ribes sp. ( Grossulariaceae ), Rhamnus frangula (Rhamnaceae) , Sanguisorba officinalis (Rosaceae) , Solidago sp. ( Asteraceae ), Syringa persica (Oleaceae) , Thymus sp. ( Lamiaceae ), and Viburnum sp. ( Caprifoliaceae ) ( Razowski, 1968; Kawabe, 1982).

Distribution. The genus Eupoecilia is distributed in the Oriental and Palaearctic regions, with some fewer species in the Australian and Ethiopian regions. In China species richness is relatively high in the eastern part, but rather low in the western part (Map. 1).
