Psenulus pallipes (Panzer, 1798), an adventive wasp species (Apoidea, Crabronidae) newly recorded in the fauna of Chile

We document the presence of the Palearctic Psenulus pallipes (Panzer, 1798) in Chile for the first time. We believe this represents an adventive population introduced into the Neotropical region most likely by accidental human transportation of nests. A map of distribution in Chile, illustrations of external morphology, and a discussion of morphological features to distinguish the introduced taxon from the Neotropical species are presented.
