Forewings usually folded flat, partially overlapping at rest. Clavus short, ending a little beyond half-way along forewing and making a distinct angle with it. Apex of confluent anal veins of forewing reaching apex of clavus.
Hemiptera - Auchenorrhyncha (cicadas, planthoppers)
Includes cidadas, spittle bugs, leafhoppers and planthoppers. Monophyly of the Hemiptera s. str. remains controversal. Carver et al. (1991) suggest the complex tymbal acoustic system and the aristoid antennal flagellum as monophyletic for the group. Labium, originates from the posterior region of the head, near to the occiput, no intervening sclerotic gula is present.
Murray (2009 and updates) provides keys to Australian and New Zealand Auchenorrhyncha.
