Scotia canities (Grote) : Köhler, 1967 : 299 , fig. 65 (new combination). Diagnosis. Agrotis canities differs from other South American species of Agrotis by the following combination of characters: 1) forewing length in males 15.2–17.3 mm, in females 15.3–15.6 mm; 2) ground color light grayish brown; 3) in male genitalia vesica 8 × as long as aedeagus; 4) right basal diverticulum absent; and 5) in female genitalia appendix bursae 6–7 × as long as corpus bursae. Redescription. Male ( Figs 34, 35 ). Head . Frons central projection small, with raised edge of rough surface, not projected anteriorly, some specimens with central projection without raised edge. Antenna biserrate, widest at 1/5 its length, gradually tapering to apex, widest segment 2 × as wide as central shaft, anterior process 1.3 × as wide as posterior process. Thorax . Patagium dark grayish brown, with black medial line; tegulum light gray, with blackish marginal line widened anteriorly. Forewing length 15.2–17.3 mm; ground color light grayish brown; subcostal band dark grayish brown; basal area darker than ground color; basal line black, double, undifferentiated in some specimens; antemedial line black, double, convex between veins, extended as a sharp tooth between 1A+2A vein and posterior margin, never close to medial line; claviform spot black; orbicular spot strongly oval, extending toward reniform spot, contiguous in some specimens, concolorous with ground color, black edged with grayish center; reniform spot concolorous with orbicular spot, distal margin with no streak; discal cell concolorous with ground color, with black streak of variable width joining both spots; medial line faint, as a dark thick waved band; postmedial line black, double, concave between veins, some specimens with a single line, extending on veins to apical margin; subterminal line faint, light brown and black edged, concave between veins, in some specimens like arrows, never contiguous with postmedial line; terminal line a series of darkish lunulae between veins; fringe concolorous with forewing ground color with dark transverse lines at veins apex. Hind wing iridescent; fringe iridescent. Abdomen . Light grayish brown, with dark dorsal line. Genitalia ( Fig. 59 ). Uncus sinuous. Clavus cylindrical, short, 2 × as long as wide. Ampulla 1/5 × as long as valve, basal 1/3 expanded, then narrowed to half its widest diameter; saccus hemispherical. Vesica ( Fig. 77 ) 8 × as long as aedeagus, consisting of four wide loops, right basal diverticulum absent, vesica slightly swollen on apical 1/5. Female ( Fig. 36 ). Differences from male. Forewing length: 15.3–15.6 mm; antenna filiform; ground color light grayish brown to grayish brown; hind wing iridescent or with dark brown veins and anal and apical margins diffuse dark brown. Genitalia ( Fig. 90 ). Posterior apophysis 1.5 × as long as anterior apophysis; ductus bursae 2 × as long as anterior apophysis; corpus bursae 7 × as long as anterior apophysis, signum absent, apex subtriangular; appendix bursae 6–7 × as long as corpus bursae, consisting of six wide loops, apex globose; ductus seminalis originating laterally near corpus bursae apex. Distribution. Center and North of Argentina ( Fig. 107 ). Specht et al. (2004 , 2005 ) cite this species for South of Brazil . Material examined. ( 21 ♂ , 5 ♀). ARGENTINA : Catamarca.
