Abstract

Caragonia gen. nov. is described and placed in the nominate tribe of Cicadellinae, based on a previous phylogenetic analysis of the closely related genus Balacha Melichar. The new genus can be distinguished from other Neotropical genera of Cicadellini by a combination of the following features: crown slightly produced anteriorly, forming nearly a right angle with frons in lateral view; pronotum wider than head with lateral margins convergent anteriorly; female sternite VII with a median longitudinal elevated fold, posterior margin with narrow and deep concavity, lateral margins well produced posteriorly; teeth of second valvulae of ovipositor gradually declivous posteriorly; aedeagus cylindrical and elongate, shaft with base directed anteriorly and then curving gradually posteriorly, with apical pair of processes; paraphyses with stalk longer than rami; and subgenital plates with apex broadly round. Caragonia bella sp. nov. is described and illustrated from Southeastern Brazil (São Paulo and Minas Gerais states) and assigned as the type-species of Caragonia gen. nov. Tettigonia monstruosa Signoret, previously placed in the genus Caragonalia Young, is transferred to the new genus based on characters of the external morphology and female genitalia.
