Acarodynerus

Female Acarodynerus clypeatus, from Saussure (1852).


Belongs within: Eumeninae.

Acarodynerus is an Australian genus of mason wasps characterised by the presence of a pair of deep cavities on the posterior face of the propodeum that function as acarinaria (Giordani Soika 1961).

Characters (from Giordani Soika 1961): Overall aspect elongate, sub-cylindrical, medium to large in size. Mesosoma elongate, postscutellum horizontal or slightly oblique, moderately convex, not transversely keeled, often with a slight median longitudinal depression; dorsal face of propodeum well developed so postscutellum does not form part of posterior face of mesosoma; lower part of posterior face of propodeum bearing large convex, shiny area with two large cavities on either side of median line, in which some mites are often observed. First metasomal tergite sub-truncate at the base, sub-cylindrical.
