Dellapé, Gimena, 2015, Description of the female terminalia of twenty species of Proconiini (Hemiptera: Cicadellidae) from Argentina, Zootaxa 3915 (4), pp. 521-539 : 524

Diestostemma ptolyca Distant 1908

Diagnosis. Coloration of crown, pronotum and scutellum ocher; pronotum dotted, without tubercles; forewings whitish, with dark line located between claval suture and radial vein, on basal part of wing. Male: aedeagus with pair of short sharp basal processes; paraphyses paired and long in base of aedeagus.

Female terminalia. Abdominal sternite VII, in ventral view ( Fig. 5 ), with lateral margins slightly convergent posteriorly, lateroposterior margins broadly rounded, and posterior margin with conspicuous median lobe; surface with scattered microsetae. Pygofer, in lateral view, slightly produced posteriorly; surface with scattered microsetae. First valvifers, in lateral view, longer than tall; with small spiniform processes on ventral region. First ovipositor valvulae, in lateral view, slightly broadened beyond basal curvature and then narrowing gradually toward apex; dorsal sculptured area formed by scale-like processes arranged in oblique lines; ventral sculptured area formed by scale-like irregular processes; apex acute ( Fig. 25 ), with denticles on dorsal margin. Second valvulae, in lateral view, broadened beyond basal curvature and then narrowing gradually toward apex; dorsal margin of blade bearing 78 to 84 continuous teeth, each tooth subtriangular, with denticles on anterior and posterior margins ( Fig. 45 ); some ducts extending toward base of teeth and toward apical blade portion; apex narrowly truncate, with denticles along entire margin ( Fig. 65 ); without preapical ventral prominence. Gonoplacs, in lateral view, with scattered microsetae on ventral margin and a few strong setae on apex; apex rounded.
