Acaenitinae
Acaenitinae is a subfamily of parasitoid wasps within Ichneumonidae, comprising 28 genera distributed across all continents except Antarctica. The subfamily is poorly known biologically, with only one species (Acaenitus dubitator) reared to confirm its life history as a koinobiont endoparasitoid of weevil larvae. Females possess a distinctive large triangular projecting genital plate, a key diagnostic feature. Traditional tribal classification into Acaenitini and Coleocentrini remains debated, with molecular studies challenging the monophyly of Coleocentrini.
