Irenangelus

Irenangelus is a genus of kleptoparasitic spider wasps in the subfamily Ceropalinae of the family Pompilidae. The genus has a pantropical distribution, occurring in the Oriental, Neotropical, Australian, eastern Palearctic, and Madagascan zoogeographic regions, with the highest diversity found in the Neotropics.

Irenangelus is closely related to the more widespread genus Ceropales, with both forming a monophyletic subfamily, Ceropalinae, within the Pompilidae. This subfamily is considered the most basal lineage of the Pompilidae. However, this classification is debated due to the kleptoparasitic life history of ceropalines. Current research suggests that Ceropalinae and other pompilids evolved from a common ectoparasitoid ancestor.
