Summary

Aptesini is a tribe of ichneumon wasps within the family Ichneumonidae, consisting of 24 genera and around 134 species in North America alone.

Physical Characteristics

Wings fully developed, the front wing longer than the thorax. The second recurrent vein has a single bulla. The sternaulus ends just below the lower hind corner of the mesopleurum. The apical truncation of the scape is strongly oblique. Males may have a face marked with white or yellow. The dorsal rim of the metanotum has a posterior sublateral projection. The propodeum features longitudinal carinae, and when a transverse carina is present, it is typically the apical carina instead of the basal one.
