The Sharpshooter Genus Geitogonalia Young: Descriptions of a New Brazilian Species and of the Female of Geitogonalia quatuordecimmaculata (Taschenberg) (Hemiptera: Cicadellidae)

The sharpshooter genus Geitogonalia Young was so far known from a single species from Southeastern Brasil—Geitogonalia quatuordecimmaculata (Taschenberg). A new species, Geitogonalia viridis, is described and illustrated in this paper based on males and females from the state of Rio de Janeiro. In addition, the female of G. quatuordecimmaculata is for the first time described and illustrated in detail. Geitogonalia quatuordecimmaculata is a dark species marked with bright orange on the fore wings, whereas the new species has the corium and clavus of the fore wings mostly green. The paraphyses are well developed in G. quatuordecimmaculata, with elongate rami, whereas they are inconspicuous in G. viridis, with the rami modified as a pair of very small sclerites.
