Pirquelia vidali Urra sp. nov.

(Figs. 15, 16, 33, 34, 50, 51).

Diagnosis. Pirquelia vidali can be distinguished from P. aragoni by its color pattern, FW is completely yellow, while P. aragoni has a shortened diagonal fascia that extends from the tornus to the discal cell. In the male of P. vidali the juxta has an acute dorsoposterior process, the process of the cucullus is straight and acute; in the female the antrum is subconical. In P. aragoni the juxta is sub-rectangular, the cucullus process curves ventrally, and in the female the antrum is tubular (Urra 2013a).
