Verdanus is a genus of true bugs belonging to the family Cicadellidae.
The genus Verdanus was established by Oman (1949). The author distinguished Verdanus from the genus Diplocolenus on the base of aedeagal differences. Several authors considered it a subgenus of Diplocolenus. The genus Verdanus includes two subgenera, Verdanus and Erdianus.
The species of this holarctic genus are mainly found in Eurasia and Northern America, especially in meadows of the mountain regions.
Species within this genus include:
Verdanus species can reach a body length of about . These leafhoppers are pale green with dark brown or black venter and legs. In Eridianus subgenus, aedeagus shows a basal apodeme strongly produced laterally, while connective have arms parallel distally and fused over part of length. Verdanus subgenus has a long and narrow aedeagus and connective with arms divergent distally and abructly angled to midline.
Adults are on wing from mid March to mid August.
