The genus Orionis Shaw (Hymenoptera, Braconidae, Euphorinae) in the Old World

The euphorine braconid genus Orionis Shaw, 1987 is found to be more diverse in the Old World than had previously been recognised. Orionis was regarded previously as largely Neotropical, with one Oriental species (Orionis orientalis Shimbori & Shaw, 2016) known from Thailand, but we recognise an additional three species from the Oriental and Palaearctic regions. Three species of Euphorinae are transferred to Orionis Shaw, 1987 and are new combinations: Orionis coxator (Belokobylskij, 1995), comb. nov., Orionis erratus (Chen & van Achterberg, 1997), comb. nov., and Orionis flavifacies (Belokobylskij, 2000), comb. nov. Previously known from the Far Eastern Palaearctic, O. coxator has surprisingly been found in Europe, in Belgium, England and the Netherlands. The inclusion of these species in Orionis, whereas most previous species have been described from the Neotropics, is justified by Bayesian analysis of the D2 region of 28S, Cytochrome Oxidase I barcode sequences, and morphology
