Abstract: | A new fossil digger wasp Rovnoecus klesovicus gen. et sp. nov. (Hymenoptera, Crabronidae, Pemphredoninae, Pemphredonini) is described from the Upper Eocene Rovno amber.
The genus Rovnoecus gen. nov. is characterized by an incomplete occipital carina, partly reduced second discoidal cell, and the presence of spines
on all tibiae. Rovnoecus gen. nov. is most similar to the fossil genus Eoxyloecus Budrys, 1993 from the Baltic amber. The two genera form a monophyletic group that is a sister group to the group formed by
the genera Passaloecus Shuckard, 1837 and Eopinoecus Budrys, 1993. This indirectly corroborates the hypothesis of the geographically different origin of the Rovno and Baltic
ambers. |
