There are fifteen species of Profenus globally distributed across the holarctic region. Two species are present in Britain and Ireland.
The genus Profenusa can be characterised within the Fenusini by the following characteristics. The antennal pedicel is longer than it is broad and the third segment is longer than the fourth. Both the post-genal carina and the prepectus are absent. In the forewing, the stub vein 2A+3A is straight apically. In the hindwing, the radial cell R1 is absent. The tarsal claws have a single outer tooth and a large basal lobe.
Larvae feed in blister mines in the leaves of a broad range of trees and shrubs.
