Epitranus is an Old World genus of parasitic wasps (possibly introduced to the Americas) whose hosts, so far as is known, are small moths of the Pyralidae and Tineidae. Members are distinguished by low-placed antennae on a shield overhanging the mouth, and a long, slender petiole (Bouček 1988).
Characters (from Bouček 1988): Antennae inserted very low, on a shield overhanging mouth, scrobes virtually absent; forewing with marginal vein very long, stigmal rudimentary, postmarginal absent; apex of hind tibia tapering into a strong spine extended far beyond insertion of tarsus; gaster attached at coxae, on slender striate petiole which longer than half of gaster.
