(A–D after Adams 1971, modified). Material examined. “ Argentina : Neuquén , Pucará , 30 Nov. 1959 , F. H. Walz col.” ( 1♀ NMNH ). Distribution ( Fig. 43 ). Chile (Ñuble); Argentina ( Neuquén ). Principal characteristics. Head pale with articulating areas of antennal sockets dark, their border confluent with frontoclypeal triangle; anterior spots to anterior tentorial pits dark; borders of ocelli and vertex dark brown; antennae pale brown.

Legs brown; mid- and forefemur with a pair of subapical dark marks; hind femur pale; tarsi pale brown, except for dark brown apical tarsomere; female procoxa laterally with many short setae arising from protuberant bases. Wings with rounded tips, membrane irregularly stained with grayish-brown suffusions and amber spots, veins mainly brown with some regions pale yellow, pterostigma barely perceptible ( Fig. 36 B); forewing with dark spots around the wing margin and along anterior radial trace, MP2 fork basal of union of CuA and CuP; hindwing diffusely smoky, mainly in the distal half; nygmata dark brown. Male ( Figs. 38 A, B). Ninth gonocoxites elongated, crescent-shaped in lateral view with some setae at apex; ninth gonapophysis elongate tapering towards the apex; complex of tenth gonocoxites C-shaped in lateral view with two processes. Hypandrium internum elongated with winglike lobes fused on the midline ( Adams 1971 ). Female ( Figs. 38 C, D). Eighth sternite with numerous setae on anterior apex, posterior lobes are short and rounded; spermathecae slightly bent with basal portion spherical ( Adams 1971 ).
