Identification
Distinguished from other Argidae by combination of abdominal coloration (brown surface) and presumably other subtle morphological features of the Aprosthema. Separation from requires examination of specific diagnostic characters such as saw structure, wing venation details, and body proportions; precise distinguishing features for this specifically are not well documented in accessible literature.

Appearance
exhibit the typical Argidae body plan with a broad connection between and (lacking the narrow ' waist' of many other Hymenoptera). The name 'brunniventre' (brown-bellied) indicates brownish abdominal coloration. are simple, not elbowed or clubbed. Wings are membranous with reduced venation characteristic of the .
Distribution
Specific geographic range is poorly documented due to limited observations (only 2 records in iNaturalist). The Aprosthema has a Palearctic distribution, suggesting this likely occurs in Europe or adjacent regions.
