Dirhininae
Dirhininae is a subfamily of chalcidid wasps established by Ashmead in 1904, containing four genera and over 100 species, many of which remain undescribed. Members of the tribe Dirhinini are distinguished by a pair of prominent head horns and are primarily distributed in tropical regions. These wasps are parasitoids that develop within various Brachycera flies, with the adult wasp using its horns, mandibles, and robust body to forcefully emerge from the host.
