China. The type specimens are deposited in the Insect Holotype (cid:2), paratypes 2 (cid:2) (cid:2), West Tianmu Collections ofShandong Agricultural University. Mountain area ( 30#22∃N, 119# 26∃E; alt. 400 m), ZhejiangProvince, 19 July 2000, collected by MO Tie(cid:1) Epidiplosis dactylina sp. nov. (Figs(cid:2)1(cid:1)5) Lu. The new species is similar to Epidiplosisbicornuta Liet Etymology. The specific name is derived from the Bu2006, but differs mainly in the characters of genitalia Latin word dactylinus!, referring to the shape of in the following aspects: 1) dorsoapical projection of dorsoapical projection of the gonocoxite. gonocoxite fingered, with a long seta near apex; 2) gonostylus markedlyarched, only with alongsetaathalf Key words(cid:1) Diptera, Cecidomyiidae, Epidiplosis, new species. * Correspondingauthor.
