Pseudalastor concolor, copyright Reiner Richter.

Belongs within: Eumeninae.

Pseudalastor is a genus of relatively robust potter wasps in which the female bears a large, raised oval plate on the vertex of the head.

Characters (from Giordani Soika 1962): Mesosoma squat, sub-cylindrical. Postscutellum rounded posteriorly, forming part of the posterior face of the mesosoma. Propodeum very depressed on sides, lateral margins subrectilinear and almost parallel; lateral carina strongly developed, meeting with lower carina to form an almost right angle. First tergite subtruncate at base, much narrower than the following tergite. Vertex of female with a large transverse oval plate, much larger than ocellar area, with sharp contours, sharply raised above the remaining surface of the vertex, provided in center with a round dimple bearing short and dense hair. Aedeagus with very long basal lobes, ribbon-like, depressed, arched towards apex of aedeagus.
