Head. In dorsal view, including eyes, about four times wider than long, about the same width as anterior margin of pronotum ( Fig 1b ). In ventral view, rostrum surpassing posterior coxa. Thorax. In dorsal view, pronotum with the length slightly less than the mesonotum; metanotum very small when compared with the pronotum and mesonotum ( Fig 1b ). Wing cases developed, reaching abdominal segments, shaded in the upper region ( Fig 1a ). In the foreleg, femur with long and sharp posterior tooth, slightly bent forward, about two and a half times longer than the width of its base; small and sharp accessory tooth present; intermediate tooth with projection in one of its sides; femoral comb usually with six teeth (femoral formula 2-1-6), the first tooth wider and projected forward ( Fig 2b ). Tibia arched, flattened laterally; apical tooth long; blade of tibia with a distinct tooth; point of blade of tibia developed and separated from the apical tooth by strong incision ( Fig 2b ). Tarsi developed, folded over the inner surface of the tibia, two segmented, the apex much longer and fitted with a pair of claws of unequal sizes ( Fig 2a ). In the hind legs, tibia with four apical spines, in some cases, internally with a very smaller spine ( Fig 4a ). Tarsi two segmented, the apical much longer and fitted with a pair of claws of unequal sizes. Table 1 Measurements (mm) (mean ± standard deviation) of fifth-instar nymphs cicadas collected from coffee trees in Brazil.

The size varies according to the development of the nymph, so it may be reduced with the distal extremity of the hind wing almost reaching the apex of the abdomen, or elongated, with the distal extremity of the hind wing reaching the middle of the abdomen. Female: 8th and 9th sternite with two sharp protrusions in the posterior margin ( Fig 3a ). Male: 10th sternite with two globular protrusions in the anterior margin ( Fig 3b ).
