This is a small genus of only three species distributed within the Palaearctic region. In Britain there is one species. The genus is absent from Ireland.

The genus Stauronematus can be characterised within the Nematinae by the following features. They are similar to the genus Pristiphora but the tarsal claws are distinctive through having a pronounced basal lobe and an inner tooth that is longer than the apical tooth. In the forewing, cell c is at least twice the width of vein R at the point where vein Rs+M meets vein R.

Larvae feed on the leaves of species within the Salicaceae. They are unique in constructing a palisade of dried saliva turrets around themselves, the purpose of which is uncertain.
