Description.

A detailed description and images of the species in Papp (1991) and Fernandez-Triana et al. (2013).

Hosts.

Comments.

This species has a widespread distribution in the western Palaearctic Region and it also has relatively large morphological variation - for example, propodeum with a transverse carina (commonly) or without a transverse carina (rarely); areola size small (commonly) or relatively larger (rarely). We suspect that, under the name P. wesmaeli , there could be a complex of species. However, more collecting and study of specimens (throughout the Palaearctic Region), as well as DNA barcoding, will be needed before any attempt to unravel this complex is made.
