Genus Philaenus Stål, 1864

The species of this genus include the most polymorphic of Auchenorrhyncha (Drosopoulos, 2003, Drosopoulos et al., 2010). Eight species are now recognized, including some that have been described by careful study of the widely distributed Philaenus spumarius (L.) (e.g. Abdul-Nour & Lahoud, 1995; Drosopoulos & Remane, 2000; Remane & Drosopoulos, 2001). Tishechkin (2013) described two new Philaenus species from Iran, but he did not find Ph. spumarius among the specimens he studied.
