A review of the Neotropical sharpshooter genus Onega Distant, 1908 (Hemiptera: Cicadellidae: Cicadellini)
Tettigonia sanguinicollis Latreille, 1811, and its junior synonym Tettigonia farinaria Amyot & Serville, 1843, are herein transferred to the genus Onega Distant, 1908. Thus, the previously incertae sedis genus Paragonalia Evans, 1947 (type-species: T. sanguinicollis), becomes a new junior synonym of Onega. Onega sanguinicollis comb. nov. is redescribed and its female genitalia are described and illustrated for the first time. A color variant of Onega fassli Young, 1977 is described. Three new species of Onega are described and illustrated: O. freytagi sp. nov. from Colombia (Cauca Department), O. krameri sp. nov. from Ecuador (Azuay and Bol var provinces), and O. orphne sp. nov. from Ecuador (Bol var and Pichincha provinces). A key to all nine species now included in Onega is provided along with notes on the distribution of the species. O. bracteata Young, 1977 is newly recorded from Azuay province (Ecuador) and Jun n and Pasco departments (Peru), and O. fassli is newly recorded from Ecuador (Napo Province) and Cundimarca Department (Colombia). Records of Onega from Cuba are considered doubtful.
