Crawford, 1914
Species Guides
1Erimerus is a of chalcidoid wasps in the Torymidae, established by Crawford in 1914. It is the type genus of the Erimerinae, a small and poorly known group within the Torymidae. The genus is characterized by distinctive morphological features that separate it from other , though detailed biological information remains scarce. Erimerus are believed to be , consistent with the of related torymids, but specific associations are largely undocumented.

Identification
Erimerus can be distinguished from other Torymidae by features associated with the Erimerinae, including structural characteristics of the and ovipositor. The genus is morphologically distinct from the more speciose Toryminae, though precise diagnostic characters require examination of minute structural details. Identification to level is challenging and typically requires reference to original species descriptions.
Ecological Role
As a member of Torymidae, Erimerus likely functions as a of other insects, potentially contributing to of its . The Erimerinae is considered rare and poorly collected, suggesting either specialized ecological requirements or genuine rarity in natural .

Taxonomic History
Erimerus was established by Crawford in 1914 and has remained a valid within the redefined Erimerinae. The subfamily was historically submerged within Toryminae but has been resurrected in modern classifications based on phylogenetic studies. The genus contains relatively few described .
Data Deficiency
No observations of Erimerus are recorded in iNaturalist, and the is rarely encountered in collections. This reflects both the small size of these (typical of Chalcidoidea, often under 5 mm) and possibly genuine biological rarity or highly specialized requirements.
