Cicadellidae

Jassidae.

Leafhoppers.

Salient features of adults. Terrestrial.

Phytophagous (on trees, shrubs and herbs, variously tapping phloem or xylem, or feeding on cytoplasm). Tiny to small; 2–11 mm long; fliers; conspicuous jumpers; relatively stout bodied. Rostrum not separated from the prosternum by a gula. Antennae longer than the head, readily visible from above; consisting of short segments with a terminal, unsegmented arista that is much longer than the segments. Ocelli present; 2. Thorax not crested. Tegulae absent. Fore-wings well developed; in the resting insect sloping roof-like over the abdomen; more or less uniform in texture; with opaque cells; without costal fracture and cuneus; with a clavus; with conspicuously raised, reticulate venation, or without conspicuously raised, reticulate venation. Clavus without convergence of veins to form a Y. Hind coxae immobile (according to Woodward et al., forming transverse plates occupying most of the ventral surface of the metathorax). The posterior tibiae longitudinally keeled (with one to three spiny keels). Tarsi 3 segmented.

Tegulae absent.
