摘　　要：The genus Acricotopus Kieffer including three species from China is reviewed.Acricotopus lucens (Zetterstedt) is reexamined. Two species A. simplex sp. nov. and A.zhalingensis sp. nov. are described as male imagines. Acricotopus simplex sp. nov. was collected from Xizang, Sichuan and Qinghai Provinces; the species differs from others of the genus by the absence of hind tibial comb, temporal and clypeal seta. Acricotopus zhalingensis sp. nov. was collected from Qinghai Province; the species is recognized by a combination of characters: the larger body size; the clypeus without setae; anal lobe strongly produced, nearly hemispherical shape; inferior volsella triangular, strongly sclerotized; gonostylus with 13 very long setae. A key to the world males of the genus is presented. The generic diagnosis is emended.All the types described in this paper are deposited in Department of Biology, Nankai University,China (BDN).
