A New Species of Digger Wasps of the Gtims Belomicroides (Hymenoptera, Crabronidae, Oxybelini) from North Africa

摘要

The new species of digger wasps, Belomicroides rufus, is described from North Africa. The new species differs from the all members of the Belomicroides schmiedeknechtii species-group in the pale coloration and dense pubescence of the body. The North African fauna of the digger-wasp genus Belomicroides Kohl, 1899 included until now five representatives of the B. schmiedeknechtii species group (Antropov, 2002), which are characterized by the following features: pronotal collar without distinct median depression, postscutellum convex and without distinct lateral ridges, hypersternaulus absent, propo-deum with lateral carinae only in its dorsal part, me-tasomal sternite VI of female strongly compressed, mesosoma densely punctate, and fore trochanter andfemur without psammophores. The all known species of the group are also characterized by the dark coloration of the body, with poorly outlined, pale (white or yellow) spots on the median lobe of the clypeus, pronotal collar, and pronotal lobes. The newspecies B. rufus described below belongs to this group, but differs in the pale pattern of the body, especially of the metasoma, which is most strongly developed in comparison with those of the other congeners, and also in the dense pubescence of the head and mesosoma.
