Myrmosidae
Myrmosid Wasps
Myrmosidae is a small family of wasps in the superfamily Vespoidea, sister taxon to Sapygidae. Formerly treated as a subfamily of Mutillidae, it was elevated to family status in 2008 based on molecular and morphological evidence. Females are flightless and kleptoparasitic, entering nests of fossorial bees and wasps. The family contains approximately 10 genera and is distributed globally, though many regions remain understudied.
