The genus Psix Kozlov & Lê (Hymenoptera: Scelionidae) is revised from a worldwide perspective. Twelve species are described as new: annulatus [Cameroon], asper [Uganda], aulax [Australia], confluus [Sri Lanka], flavicoxa [Ivory Coast, Zimbabwe], fusm [Australia], lacunatus [Pakistan east to Taiwan, south to Australia], metopa [Australia], rasilis [Ivory Coast, Gambia], sulcifer [Malaysia], viriosus [India east to Philippine Is.] and watshami [E. Africa, Madagascar] . Psix abnormis Kozlov & Lê [W. Africa east to at least India], glabris‐crobus (Girault) nxomb. [Australia], olympus (Dodd) n.comb. [Australia], saccharicola (Mani) n.comb. [India], striaticeps (Dodd) n.comb. [W. Africa east to India, Madagascar] and tunetanus (Mineo and Szabó) n.comb. [Tunisia, Gambia, Ivory Coast, Saudi Arabia, S.W. Nearctic, Venezuela] are redescribed. An identification key for the species of Psix is presented. The relationships among species are discussed. The earliest derived species are generally found in Australia and southeast Asia. The more apomorphic species occur generally in Africa, southwest Asia and India. The distribution of Psix tunetanus has possibly been influenced by man. Details of the relationship with Trissolcus and Archi‐phanurus are unclear; the position of Psix within the subfamily is therefore also obscure.
