The Blasticotomidae are a very small family of sawflies, containing only 9 species in 3 genera worldwide, restricted to temperate regions of Eurasia where the larvae are specialized stem borers of ferns.

The family has antennae somewhat similar to the family Argidae, with only one or two flagellomeres, but can be distinguished by the lateral portions of the metasomal tergites being sharply creased beneath the spiracles.
