Dellapé, Gimena, 2015, Description of the female terminalia of twenty species of Proconiini (Hemiptera: Cicadellidae) from Argentina, Zootaxa 3915 (4), pp. 521-539 : 522-523

Acrogonia virescens (Metcalf 1949)

Diagnosis. General coloration greenish, with dark V-shaped spot at apex of crown; clypellus with dark spot of variable shape and size. Male: connective Y-shaped; styles elongated and curved toward the midline; aedeagus long and thin, apex sharp, and basal portion Y-shaped.

Female terminalia. Abdominal sternite VII, in ventral view ( Fig. 2 ), with lateral margins slightly parallel, lateroposterior margins broadly rounded, and posterior margin deeply emarginate bearing conspicuous median lobe inside emargination; with a few macrosetae at edges of emargination. Pygofer, in lateral view, slightly produced posteriorly; surface with scattered microsetae and macrosetae on posterior one-third of disc. First valvifers, in lateral view, longer than tall; with small spiniform processes in posterior one-third. First ovipositor valvulae, in lateral view, short and slightly rectilinear, basal portion expanded; dorsal sculptured area formed by scale-like processes arranged in oblique lines; ventral sculptured area formed by scale-like processes arranged irregularly; apex truncate with acute median projection ( Fig. 22 ). Second valvulae, in lateral view, short and slightly rectilinear; dorsal margin of blade bearing 18 to 20 noncontiguous teeth, each tooth subtriangular, declivous posteriorly, with denticles along entire dorsal margin ( Fig. 42 ); size of teeth increases from proximal portion to middle region, and then decreases towards apex, ducts extending toward teeth and toward apical blade portion; apex obtuse, forming a concavity with preapical ventral prominence ( Fig. 62 ). Gonoplacs, in lateral view, with basal half narrow, and apical half short and distinctly expanded; apex acute.
