Notes.

Recorded by Erlandsson (1972) and Schembri (1980). This species’ distributional range includes much of southern Europe as well as a few northern countries such as Austria and Slovakia; it also occurs in North Africa and the Middle East. Leptochilus regulus is another eumenine whose colouration may vary greatly between individuals; some lacking much of the yellow markings from the clypeus down to the second tergite, instead having those areas completely black ( Gusenleitner 1993).
