Hadrostethus

Hadrostethus is a genus of ichneumon wasps in the family Ichneumonidae, first described by Townes in 1969. It belongs to the diverse parasitoid wasp lineage within the suborder Apocrita. Members of this genus are part of the rich ichneumonid fauna that parasitize other insects, though specific biological details remain poorly documented. The genus is rarely encountered, with only five observations recorded on iNaturalist, indicating either genuine rarity or undercollection.
