“…After the publication of Young's (1977) monograph on the New World Cicadellini, new Neotropical genera of this tribe have been proposed by several authors (Mejdalani 1994;Nielson & Godoy 1995;Cavichioli 1996Cavichioli , 1998Cavichioli , 2000aCavichioli , 2000bCavichioli , 2003Cavichioli , 2010Takiya et al 2001Takiya et al , 2003Takiya & Cavichioli 2005;Freytag 2007;Cavichioli & Takiya 2012a;Mejdalani & Cavichioli 2013;Mejdalani et al 2014). Here we propose an additional new genus of Cicadellini, which is so far recorded from the Atlantic Forest of southern and southeastern Brazil (Paraná and Rio de Janeiro states).…”

The remarkable sharpshooter Prodigiella silvanoi gen. et sp. nov. is described and illustrated (including the external form, color, male and female terminalia) from the Atlantic Forest of southern and southeastern Brazil (states of Paraná and Rio de Janeiro). The new genus can be distinguished from other Neotropical genera of the Cicadellini by a combination of various morphological features, including an asymmetrical aedeagus with a bifid shaft and peculiar basal and apical processes and ovipositor valvula II distinctly expanded beyond basal curvature, its dorsal margin with 35–40 teeth, and ventral margin without preapical prominence. A discussion comparing Prodigiella with superficially similar taxa of the genera Macugonalia Young, 1977, Ruppeliana Young, 1977, and Versigonalia Young, 1977 is provided. The discovery of this peculiar new genus indicates that much collecting work in the remaining parts of the Atlantic Forest is clearly and urgently needed.

“…Young's (1968, 1977, 1986) revisionary study of the subfamily increased the number of sharpshooter species to more than 2000, and since then many new species and genera of sharpshooters have been described, especially from the Neotropical region (e.g. Cavichioli, 1996; Mejdalani & Emmrich, 1998; Takiya et al ., 2001). In spite of Young's (1968, 1977, 1986) enormous effort, the majority of genera of this economically important leafhopper subfamily (all species being potential vectors of xylem‐borne phytopathogenic bacteria) are still in need of taxonomic revisionary studies.…”

Abstract. Balacha currently includes six valid described species and B. caparao sp. nov., here described from Minas Gerais State, Brazil. The new taxon differs from other Balacha species in the ventrally inflated preapical aedeagal area and oblique bases of the ovipositor first valvulae. New records are as follows: B. decorata from Paraguay and Minas Gerais State (Brazil); B. distincta from Brazil; B. melanocephala from Montevideo Department (Uruguay) and Buenos Aires and Distrito Federal provinces (Argentina); and B. similis from Rio de Janeiro and Minas Gerais states (Brazil). Colombia is considered a dubious record for the genus. Phylogenetic relationships among Balacha species are examined based on a matrix of eighteen terminal taxa and sixty‐seven morphological characters. Balacha may be defined by the following synapomorphies: crown–frons transition approximately acute, crown anteriorly produced and with anterior margin subangulate, flattened pronotum continuing contour of head and mesonotum in lateral view, and teeth of second valvulae of ovipositor with anterior dorsal projection. The genus comprises two major lineages: the red Balacha clade (B. lepida(B. distincta + B. rubripennis)), and the black Balacha clade (B. caparao(B. decorata(B. melanocephala + B. similis))). Despite the scarcity of data on host plant usage of outgroup taxa (probably generalists on Lamiaceae, Lauraceae, and Asteraceae), we believe that the shift to feeding on Eryngium(Apiaceae) occurred in the ancestor of all recent Balacha species. Their small size and depressed body appear to be adaptations to living inside the rosette‐disposed leaves, and they seem to be restriced to this microhabitat. Balacha and their Eryngium hosts occur in grasslands in temperate South America, but at lower latitudes in Brazil they are isolated in alpine meadows on peaks of the southeast highlands. Dispersal between such areas through the lowland humid Atlantic forest in recent times would be difficult, thus the ancestor of Balacha was probably distributed in southeast South America before the uplift of the mountain ranges, during the late Eocene or Oligocene. This event may have triggered speciation of some lineages of the genus by vicariance.
