Melanepyris Kieffer, 1913 was proposed to accommodate a single species of Epyris Westwood, 1832, E. imicola Kieffer, 1913, mainly based on the absence of the posterior propodeal carina. Today, Melanepyris includes only two nominal species. The type-material of these species has been considered lost since their original description. In this study, the single(More)
Mesitiinae include 218 species classified in 21 genera. Hitherto all species are confined to Old World (Afrotropical, Oriental and Palaearctic Regions). However most of their species are reported from Mediterranean areas, and few species are recorded from Northern areas of Palaearctic Asia. While visiting Queensland Museum Daniele Mugrabi sort part of it(More)
