Gypona

Gypona species are leafhoppers with a transocular width of head slightly narrower than maximum pronotum width. The frontogenal suture is distant from the eye margins by more than the maximum width of the clypeus, not surpassing the antennal ledge, and extending to the anterior margin of the crown by a short distance. The median length of the crown is less than half the interocular width. The antennal ledge is carinate and oriented transversely in relation to the frons. The frons is approximately 1.4 times longer than wide, with a shagreen surface texture, not excavated below the anterior margin of the crown. The clypeus is not inflated, 1.3 times longer than wide, with parallel lateral margins and a carinate apex. The maxillary plate is produced ventrally as far as the clypeus apex. The pronotum is slightly declivous, continuous with the head declivity. The forewing is light-yellow translucent, with the basal third of the clavus frequently orange-yellow; the appendix is well developed and borders the first and second apical cells, wider medially than the maximum width of the inner apical cell. The profemur has apical setae AD1, AM1, and PD1 present and well developed. The protibia is more or less cylindrical in cross-section, with a longitudinal carina adjacent to the PD row. The first tarsomere has two rows of 6–8 minute setae on the plantar surface; the second tarsomere pecten has 2 platellae flanked by 2 tapered lateral setae on the inner and 1 on the external corner. Color polymorphism occurs in males, with the pronotum varying from mostly black with yellow maculae on the posterior third to other patterns; the mesonotum may be black with a pair of large yellow maculae near the lateral angles or yellow with a median triangular black macula.
