Diagnosis. Medium to large-sized and robust leafhoppers ( Figs 74 –83). Coloration ( Figs 1 –4, 74–83) reddishbrown, with black punctures on head and thorax, forewing with creamy spots, being the largest at middle of inner discal cell. Head ( Figs 1 , 3) short and rounded in profile. Posterodorsal corner of pro and mesotibiae with two longitudinal carinae and setae of PD row placed between the carinae. Metatibia AD row without intercalary setae between macrosetae. Subgenital plate (Figs 8, 21) with filiform setae on dorsal surface, near outer lateral margin and apex, ventral surface without filiform setae.

Coloration. Head and thorax ( Figs 1 , 14 ) background yellowish. Ocelli red. Crown and transition crown-face ( Figs 1 , 2) with black punctures. Face (Figs 2, 49) yellow, sometimes with few punctures present on frons; lorum commonly with light-yellow spot on dorsal portion; clypeus frequently with light-yellow laterally maculae near epistomal suture, lateral margins and apex. Pronotum, mesonotum and scutellum ( Figs 35 , 48 ) with many brown or black punctures; mesonotum with two pairs of small light-yellow spots near anterior margin and pair of larger spots adjacent to scutoscutelar suture. Forewing (Figs 4, 16) reddish-brown with several small creamy spots variable in size, quantity and shape, but the largest one always present at middle of inner discal cell. Legs (Figs 75, 77, 84, 85) yellow with black maculae mainly on anterior surface of pro and mesofemur, dorsal surface of pro and mesotibia, and bases of macrosetae and apex of metatibia.

Protibia ( Figs 84 , 85), in cross-section, more or less cylindrical, posterodorsal corner with two longitudinal carina, one anterior and one posterior of PD row; AV row formed by setae gradually increasing in thickness and length towards apex, longer setae only as long as diameter of protibia; AD row formed by undifferentiated setae; PD row with 3–4 long setae; dorsal surface with apical setae AD 1 absent and PD 1 developed; PV row with undifferentiated setae and 8–12 long setae; ventral surface with or without long filiform setae. Mesotibia posterodorsal corner with two longitudinal carina, one anterior and one posterior to PD row. Metafemur setal formula 2:2:1. Metatibia rows PD, AD, and AV with 24–26, 14–15, and 17–20 macrosetae, respectively; AD row without intercalary setae between macrosetae; PV row with setae of apical half formed by sequence of 1 thicker and 3–4 thinner macrosetae, ending with a single short and thin seta after the last macroseta.
