Brasema allynii

Identification to species level in Brasema requires examination of microscopic characters including wing venation, antennae segmentation, and body sculpture patterns. Members of Eupelmidae are recognized by their laterally compressed hind femora with a ventral tooth or keel, and reduced wing venation with a characteristic long marginal vein. B. allynii may be distinguished from congeners by subtle differences in mesosomal sculpture and propodeal structure, though definitive identification typically requires specialist taxonomic keys.

Recorded from Canada (Manitoba, Ontario, Prince Edward Island) and Hawaii, United States. The Hawaiian record may represent an introduced population.

As a member of Eupelmidae, likely functions as a parasitoid of other insects, potentially contributing to population regulation of host species. Specific ecological impacts remain undocumented.

• Brasema cameroniCongeneric species with overlapping distribution; distinguished by fine structural differences in propodeal sculpture and antennal proportions requiring microscopic examination.
• Eupelmus spp.Related eupelmid genus with similar body plan and compressed hind femora; Eupelmus species generally have more pronounced mesosomal sculpture and different wing proportions.
