Eragenia is a genus of mud-nesting spider wasps in the family Pompilidae, formerly included in the genus Priocnemella. The genus has some 16 described species, found in the found in the Neotropical and Nearctic realms.[1] There is only one species in North America, Eragenia tabascoensis, restricted to southern Texas.[2]

Description

[edit]

Wasps of the genus Eragenia are small, thin, and wiry. These wasps look almost identical to those of the genus Ageniella, though they are separated by two things: Eragenia has a "trough-like impression on the lateroapical margin of the clypeus", and a "curved, spine-like bristle on the apex of the anterior tibia". Eragenia tabascoensis is tawny (red, can be yellow) in color, with yellow wings. The wings are banded in black.[2]

Habitat

[edit]

This genus lives in open areas, and at the edges of forests. It can live in forests as well, hunting in sunny patches. Adults are not found at flowers.[2]

Nests

[edit]

Eragenia congrua, found in Brazil, uses Corrinid spiders to provision the nests, which are bored in soft wood.[2]
