Dellapé, Gimena, 2015, Description of the female terminalia of twenty species of Proconiini (Hemiptera: Cicadellidae) from Argentina, Zootaxa 3915 (4), pp. 521-539 : 527-528

Oncometopia expansa Melichar 1925

Diagnosis. Crown, pronotum and scutellum brownish; forewings dark grayish; anal veins separate, slightly close in their mean length. Male: subgenital plates narrow and triangular; aedeagus with four ventral processes: coarse process forked in apical third, another long pointed process, and pair of short, divergent processes.

Female terminalia. Abdominal sternite VII, in ventral view ( Fig. 12 ), with lateral margins slightly parallel, lateroposterior margins rounded, and posterior margin with shallow median emargination elongated, whose edges have a small prominence, keeled on its outer side; surface with numerous scattered microsetae. Pygofer, in lateral view, slightly produced posteriorly; surface with scattered microsetae, and a few macrosetae on ventral and posterior regions. First valvifers, in lateral view, longer than tall; with small spiniform processes on ventral region and setae in posteroventral angle. First ovipositor valvulae, in lateral view, rectilinear beyond basal curvature; dorsal sculptured area formed by scale-like processes arranged in oblique lines; ventral sculptured area formed by scale-like processes arranged irregularly; apex acute ( Fig. 32 ), with denticles on dorsal and ventral margins. Second valvulae, in lateral view, rectilinear beyond basal curvature; dorsal margin of blade bearing 37 to 38 noncontiguous teeth, each tooth subtriangular, declivous posteriorly, with denticles throughout entire dorsal margin ( Fig. 52 ); ducts extending toward teeth and toward apical blade portion; apex rounded ( Fig. 72 ), with denticles on dorsal and ventral margins; slight preapical ventral prominence. Gonoplacs, in lateral view, with a few apical setae; apex rounded.
