Name
Phrudinae Townes & Townes, 1949

Phrudinae is a worldwide subfamily of the parasitic wasp family Ichneumonidae

Phrudinae are not a natural clade. They are rarely collected and their biology is largely unknown. Two genera have been reared as endoparasitoids of Coleoptera larvae. There are 12 genera.
