Beiträge zur Verbreitung und Systematik von Halictus aeneidorsum Alfken (Hymenoptera: Apidae)

Abstract

There is given a new locality of Halictus aeneidorsum Alfk. (Saxonia, Upper Lusatia, Loemischau). As to its remarkable variability the shape of the head was found not sufficient to distinguish between aeneidorsum Alfk. and continentalis Blüthgen. There are also no differences in male genitalia, which are usually known as extraordinary different in this Apid genus.
