Pareumenes (Nortonia), de Saussure, 1869

Subgenus Nortonia de Saussure, 1869

Nortonia de Saussure, 1869: 53 View in CoL , genus.

Type species: Odynerus intermedius de Saussure, 1852 , by original designation.

Afrorhynchium Gusenleitner, 2020: 221 , genus.

Type species: Afrorhynchium dathei Gusenleitner, 2020, by original designation and monotypy. Syn. nov.

Notes. Gusenleitner (2020) described the monotypic genus Afrorhynchium providing the impunctate dorsal side of the mesosoma and the longitudinally ridged S2 as diagnostic characters, in addition to the characters of the species. These two characters considered as diagnostic of Afrorhynchium are in fact observed in other genera of Eumeninae , either combined or separately; in particular, all the species of the subgenus P. ( Nortonia View in CoL ) show a variously developed ridge on S2, and the species occurring in the Afrotropical region (including the Arabian Peninsula) are all characterized by the mostly impunctate mesosoma. Comparison of the description and some pictures of the holotype of Afrorhynchium dathei with several species of P. ( Nortonia View in CoL ) did not allow finding any character supporting the recognition of Afrorhynchium as a distinct taxon, leading to its synonymy.
