Genus Onega Distant

Onega Distant, 1908: 528 . Type species: Onega avella Distant , by original designation. Paragonia Melichar, 1926: 342 . Type species: Tettigonia sanguinicollis Latreille , by subsequent designation of China, 1938: 183 (preoccupied).

Paragonalia Evans, 1947: 163 (new name for Paragonia Melichar ). New synonym.

Diagnosis. Large cicadelline sharpshooters ranging in length from 12.4–16.8 mm; crownfrons transition with transverse carina; apex of crown and superior portion of frons with concavities; pronotum much wider than transocular width of head with lateral margins convergent anteriorly; scutellum swollen; male paraphysis, when present, a median sclerite; second valvulae of ovipositor with ventral margin rectilinear and teeth noncontiguous.

Female genitalia. Internal abdominal sternite VIII forming simple membranous plate. Pygofer ( Figs 3 G, 4I, 5C) with apex narrowly round. First valvulae ( Fig. 3 F, 4H) of ovipositor with base in ventral view with short lateral external projection connecting to valvifers; inner side with lobed evagination. Second valvulae of ovipositor ( Fig. 5 D) in lateral view regularly broadened along apical 3/4 beyond basal curvature, ventral margin rectilinear; blade bearing 43–45 noncontiguous teeth, each tooth ( Fig. 5 F) subtriangular, irregularly emarginated, and declivous posteriorly; preapical area of blade with denticles more conspicuous on ventral area; apex ( Fig. 5 F) round.
