Verdanus is a genus of true bugs belonging to the family Cicadellidae.
Taxonomy 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. A. Guglielmino & C.

Distribution and habitat The species of this holarctic genus are mainly found in Eurasia and Northern America, especially in meadows of the mountain regions.
Species Species within this genus include: Verdanus abdominalis (Fabricius, 1803) Verdanus bensoni China, 1933) Verdanus caucasicus (Emeljanov 1962) Verdanus ciscaucasicus (Emeljanov, 1964 Verdanus evansi (Ashmead, 1904) Verdanus hardei (Dlabola 1980) 80 Verdanus intermedius (Emeljanov 1964) Verdanus limbatellus (Zetterstedt 1828) Verdanus logvinenkoae (Emeljanov 1964) Verdanus monticola (Linnavuori 1958) Verdanus nigricans (Kirschbaum 1868) Verdanus obenbergeri Dlabola 1945 Verdanus orientalis (Ribaut 1936) Verdanus oseticus (Emeljanov 1964) Verdanus pazoukii Dlabola 1980 Verdanus penthopitta (Walker 1851) Verdanus quadrivirgatus (Horvath 1884)
Description 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.
