Diagnosis. This genus can be identified by the following characters: body robust, large and elongate with coloration brown to reddish-brown; anterior margin of head rounded with three parallel transverse carinae; crown broad with two to eight distinct, symmetrically arranged black spots; ocelli on anterior margin of head, close to eyes; face broad; frontoclypeus broad basally and narrow apically, not tumid; clypeal suture present; clypellus broadening distally, medially elevated; lora broad; gena medially concave; antennae relatively short, antennal base near anterodorsal corners of eyes; antennal ledge strong and oblique; head equal to or wider than pronotum; pronotum with six to ten dark spots in irregular row near anterior margin, lateral margin carinate; scutellum with or without dark spots; forewing macropterous, slightly to densely clothed with fine setae, with four apical cells and three subapical cells, two closed, cross vein present between claval suture and A1, A1 and A2, appendix large; fore femur with anteromedial (AM1) seta and with two or more additional proximal macrosetae, intercalary (IC) row with fine setae apically, anteroventral (AV) row with long macrosetae on ventral margin; protibia dorsal surface rounded, dorsal rows with 1+10 or more setae; metafemur with apical setal formula 2+2+1 or 2+2+1+1, metatibia dorsal surface with numerous stout long setae.

Male genitalia: pygofer basolateral membranous cleft present, without macrosetae, side apically tapering and attenuate, with or without apical process; valve articulated with pygofer at point; subgenital plate with macrosetae arising from near lateral margin, scattered; style with apical process elongate or short, lateral lobe variable; connective short, Y or H-shaped, articulated with aedeagus; aedeagus long and single, curved dorsad, with one or two pairs of lateral processes, gonopore apical; anal tube large, sclerotized laterally and dorsally, linked to triangular sclerotized plates and aedeagus by membrane.

Female genitalia: pygofer with numerous macrosetae; ovipositor not or extended posteriorly beyond apex of pygofer; the first valvulae ( Fig. 2 , O, P) convex apically a-third, dorsal margin sculpturing pattern strigate texture, without conspicuously ventroapical sculpturing; the second valvulae ( Fig. 2 , Q, R) slender, hardly with middle dorsal tooth, dorsal margin with serrate teeth about apically a-third, teeth large; the third valvulae ( Fig. 2 , S) sheathshaped, connected with pygofer by membrane, with several setae on ventrolateral surface.

Biology. Dwightlina leafhoppers inhabit rain forests and have been collected at lights.

Distribution. Afrotropical Region.
