They have membranous wings with delicate venation and can be confused with members of other Fulgoroid families such as the Issidae and Tropiduchidae.

Some of their key features are a frons ("face") that is longer than wide and a reticulate wing venation.

The antenna arises well below the eye, has the base clubbed and flagellum unsegmented.

On the hind leg, the second tarsal segment has an apical spine arising from it.

An important family character is found in the shape of the male genital structure, a style that is longer than broad.
