The Macrophya planata species group is proposed and defined by mesoscutellum very fiat 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; postoeellar 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.
A new species ofEmphytopsis Wei ＆ Nie from Guangxi, China is described： E. maculoclypea Wei sp. nov. The new species resembles E. punctata Wei ＆ Nie, 1998 and E. unimaculata Wei, 20ll but differs from them in the anterior of clypeus and posterior of hind orbit black; the upper comer of mesepistemum and the ventral side of middle and hind coxae with black spot; the postocellar area fiat, not above temple; the lateral furrows very fine and weak; and the area below pore line in female lancet about 1.8x as high as broad. A key to the known species of the genus is provided.
