Diagnosis. This genus can be identified by the following characters: body medium size to large leafhoppers with coloration yellow, green, brown or black, sometimes with reddish longitudinal stripes; head subequal to, wider than, or narrower than pronotum; discal portion of crown glabrous with radial or longitudinal striae, anterior margin with three sharp transverse carinae and two smooth sulci or with numerous irregular carinae and sulci; ocelli close to eyes, on anterior margin of head; face with frontoclypeus strongly broadening upward or not, anteclypeus expanded apically, lorum subequal to or wider than clypellus near base, antennae short, antennal pits at near posteroventral (lower) corners of eyes in facial view, antennal ledge carinate or weakly carinate; lateral frontal sutures reaching corresponding ocellus; pronotum with lateral margin carinate; forewings with inner anteapical cell open, cross vein present between claval suture and A1, A1 and A2, appendix distinct; fore femur with anteromedial (AM1) seta present and with one or more additional proximal macrosetae, intercalary (IC) row with one row of fine long setae or several thick setae at the base of IC, anteroventral (AV) row with relatively long macrosetae; protibia dorsal surface rounded and convex, chaetotaxy on dorsal surface with 5+5, 6+6, 7+7 setae or different combinations as 5+6 setae; metafemur with apical setal formula 2+2+1.

Male genitalia: pygofer sides strongly prolonged, elongate conical, ventral margins with hook-like or falcate process or not, with numerous macrosetae near caudal margin; valve triangular; subgenital plates with apical length and shape variable, with or without macrosetae; style with apical process long, lateral lobe blunt or pronounced; connective Y-shaped or U-shaped, stem extended posteriorly with a pair of long paraphyses or pseudostyles, fused or articulated with arms; aedeagus lying far above connective and linked to it by a thin membrane; aedeagal shaft single, tubular or digitate, recurved dorsally, symmetrical or asymmetrical, with or without apical process; gonopore usually on ventral surface; anal tube small, largely concealed by pygofer, sclerotized.

Female genitalia: pygofer with numerous macrosetae; first valvulae long and narrow, subapical margin with irregular fluctuation or notched subapically, dorsal sculpturing pattern strigate; dorsal margin of the second valvulae without median tooth, with blunt teeth restricted to approximately apical one-fourth.

Distribution. Afrotropical, Palaearctic regions.
