( 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 ). Description Male ( Fig. 15 ). Wingspan: 17.1 mm (n = 1). Head. Front and vertex light yellow; flagellum of antenna grey, annulated, scape grey, pecten and haustellum light yellow; labial palpus light yellow, speckled with brown ( Fig. 16 ). Thorax. Yellow, tegulae of same color. FW yellow, fringes of same color. HW light yellow, fringes of same color. Fore- and midlegs grey, hindleg light yellow; hindtibia with piliform scales light yellow. Abdomen. Light yellow. Terga with spiniform setae arranged in two rows of patches ( Fig. 34 ). Male genitalia ( Fig. 50 ). Uncus subtriangular, gnathos subsquare, shorter than uncus; juxta suboval, with dorsoposterior process acute; valva longer than wide, distal half narrower, cucullus acute with sclerotized band on inner surface and distal acute internal process, sacculus without processes, half as long as valva; phallus curved, 0.83 times valva length, apex acute ( Fig. 50b ), vesica unarmed. Female. Color pattern similar to male. Wingspan: 19.1 mm (n = 1). FIGURES 13–18. Habitus (scale bar = 5.0 mm) and labial palpi (scale bar = 0.5 mm) of the new species of Oecophoridae .

Apophysis posterioris 2.3 times as long as apophysis anterioris; ostium bursae suboval; antrum sclerotized, subconical; lamella antevaginalis sclerotized; ductus bursae membranous, 2.0 times as long as corpus bursae, corpus bursae subspherical, signum a suboval dentate plate.
