Leafhoppers in the genus Gyponana are large and robust. There are 49 species in America north of Mexico, and most of the species closely resemble each other.
In genus Gyponana, the head is narrower than the pronotum, and the two ocelli are close set, straddling the midline of the vertex.
A trait of genus Gyponana is the sharp margin of the head, and the nearly horizontal face. The leafhopper at left may be Gyponana serpenta, a forest dweller.
