Dellapé, Gimena, 2015, Description of the female terminalia of twenty species of Proconiini (Hemiptera: Cicadellidae) from Argentina, Zootaxa 3915 (4), pp. 521-539 : 525

Homalodisca ignorata Melichar 1924

Diagnosis. Crown and pronotum light brown; crown with dark triangular spot on disc; clypeus with large, black ventral macula; anal veins fused along a considerable distance. Male: processes of pygofer not attaining pygofer apex; shaft of aedeagus robust with gonopore conspicuously visible, and with pair of ventral processes.

Female terminalia. Abdominal sternite VII, in ventral view ( Fig. 7 ), with lateral margins parallel, lateroposterior margins slightly convergent posteriorly, and posterior margin with shallow elongated median emargination; surface with numerous scattered microsetae. Pygofer, in lateral view, moderately produced posteriorly; surface with scattered microsetae. First valvifers, in lateral view, subquadrate, with small spiniform processes on ventral region and a few fine setae on posterior margin. First ovipositor valvulae, in lateral view, rectilinear beyond basal curvature; dorsal and ventral sculptured areas formed mostly by scale-like processes arranged in oblique lines; apex acute and slightly curved downward ( Fig. 27 ), with denticles on dorsal and ventral margins. Second valvulae, in lateral view, rectilinear beyond basal curvature; dorsal margin of blade bearing 32 to 34 noncontiguous teeth, each tooth triangular, with denticles along entire dorsal margin ( Fig. 47 ); there are no ducts, but there are pores near the base of each tooth; apex rounded ( Fig. 67 ), with strong denticles on ventral margin; preapical ventral prominence conspicuous. Gonoplacs, in lateral view, with small spiniform processes on ventral margin; apex rounded.
