Abstract. A new genus, Spinagonalia , and new species, S. rubrovitta , are described and illustrated from Southern Brazil. Specimens of the new species were collected on citrus trees and grapevines. The new genus can be distinguished from other Neotropical Cicadellinae by the anal tube segment X with a pair of basal ventrolateral processes, which are acute and curved posteriorly.

Resumo. Um novo gênero, Spinagonalia , e uma nova espécie, S. rubrovittata , são descritos e ilustrados do Sul do Brasil. Os espécimes foram coletados em citros e videiras. O novo gênero pode ser distinguido dos demais Cicadellinae neotropicais pela presença de um par de processos na base do segmento X do tubo anal, os quais são agudos e curvados posteriormente.
