Review of Atopopompilus (Hymenoptera: Pompilidae) from China, with description of one new species and an updated key to the world species

Abstract

Atopopompilus Arnold, 1937 is a small genus of Pompilini. Most species are distributed in the Afro-tropical Region, but there are a few in the Oriental region. In this contribution, the taxonomy of Atopopompilus from China is addressed, to ascertain species diversity and distribution in the country. One new species, Atopopompilus robusticarinatus Yang & Ma, sp. nov., is described from Yunnan and Tibet. The new species is similar to Atopopompilus daedalus daedalus (Bingham, 1896), but can be distinguished by the facial carina, the posterior margin of the pronotum and the male SGP and genitalia. In addition, the geographic distribution of and a key to the world species of Atopopompilus are updated. This study increased the number of known species Atopopompilus, and expanded the known distribution of the genus to the Palearctic region.
