Material examined. Holotype, “ Chile: Malleco , Termas de Tolhuaca, 46 Km N. Curacautín, 38°14’S −71°44’W, 15.iii.1986, L.E. Pena G.” (1♀ NMNH).

Distribution ( Fig. 43 ). Chile (Malleco, Ñuble); Argentina (Neuquén).

Principal characteristics. Head light brown ( Fig. 36 A); genae dark brown; labial and maxillary palpi pale brown with dark brown apex; antennae yellow; scape as long as wide; flagellomeres almost as long as wide, densely covered with pale setae. Pronotum light brown, with lateral dark stripes on the sides and long pale brown setae, mainly on the sides; meso- and metanota light brown with black spots and dark brown setae. Legs pale yellow; densely covered by pale amber setae; anterior and mid-femur with a black stripe. Wings hyaline, posterodistally slightly falcate, membrane irregularly stained with light amber, venation with an irregular pigmentation pattern consisting of numerous brown spots on a pale yellow background ( Fig. 36 A), two to four nygmata; forewing with many fuscous maculae, and some of them are prominent: a biangulate apical mark, marks around the wing margin, numerous marks along anterior radial trace and CuA; hindwing with some dark spots, mainly in the wing margin. Abdomen dark brown covered by small dark brown setae.

Male. Ninth gonocoxites arched and setose, crescent-shaped in lateral view and ending with membranous lobe; complex of tenth gonocoxites joined and crescent-shaped in lateral view; hypandrium internum present ( Oswald, 1994).

Female ( Figs. 36 B, C). Fused eighth gonocoxites + gonapophyses subquadrate in ventral view with a prominent anteromedial sclerotized process; fused ninth gonapophyses (subgenitalia of Oswald 1994) composed of a sclerotized transverse arch, which arise as a pair of elongate and concave lobes. Ninth gonocoxites free, elongated, and reniform, and articulated to a pair of processes on posterior margin of ninth tergite; two bilobed spermathecae present.
