A Revision of Digger Wasps of the Genus Oxybelomorpha (Hymenoptera, Crabronidae, Oxybelini): 2. The O.funesta and O. gessi Species-groups

摘要

Two species-groups of the genus Oxybelomorpha Brauns, 1897 from South Africa are revised: O. fu-nesta, monotypic group, and O. gessi, a previously undistinguished group including five new species: O. gessi, O. imitans, O. nitens, O. pulawskii, and O.sgessae. The second part of the revision of digger wasps of the genus Oxybelomorpha Brauns, 1897 treats two South-African (Fig. 1) groups of species having a similar structure of scales of the metanotum: depressed on the upper side, rounded along the outer margin (including apex), and forming obtuse inner preapical angles directed to the median line.
