| Abstract:The Macrophya planata species group is proposed and defined by mesoscutellum very flat with sharp lateral carina and the dorsal side of some antennomeres white. A new species of the group from Tibet, China is described: Macrophya acutiscutellaris Wei, Li & Heng sp. nov.. The new species is similar to M. pseudoplanata Saini et al., 1996, but differs from the latter in body length 13.5 mm in female; apical third of hind tibia entirely black; antenna 2.5 times as long as head breadth; postocellar area 1.6 times as broad as long; harpe weakly narrowed toward apex. A key to all known species of Macrophya planata group is provided. Type specimens of this new species are deposited in the Insect Collection of Central South University of Forestry and Technology, Changsha, Hunan, China. |
