Syntypes : ♂ ♀ [ Argentina ], [Tucumán], Tafí, San José, 2500m , IV-1933 (Schreiter) (IMLA). Examined. Scotia schreiteri ( Köhler): Köhler, 1967 : 317, fig. 58 (new combination). Agrotis schreiteri ( Köhler): Köhler, 1973 : 17 (new combination); Poole, 1989 : 55 (world noctuid checklist). Feltia schreiteri (Köhler) : Lafontaine, 2004 : 220 (new combination). Diagnosis. Agrotis schreiteri differs from other South American species of Agrotis by the following combination of characters: 1) male antenna bipectinate, widest segment 3 × as wide as central shaft; 2) patagium darker than thorax and tegulum lighter than thorax; 3) forewing basal dash thick, extending from wing base to beyond claviform spot, not reaching wing outer margin; 4) basal, antemedial, and postmedial lines undifferentiated; and 5) in male genitalia clavus barely differentiated as an area of piliform setae. Redescription. Male ( Fig. 37 ). Head . Frons central projection small, with raised edge of rough surface, projected anteriorly into a point. Antenna bipectinate, widest at half its length, gradually tapering to apex, widest segment 3 × as wide as central shaft, anterior process 2 × as wide as posterior process. Thorax . Patagium darker than thorax, with black medial line; tegulum lighter than thorax, with no lines. Forewing length 14.5–15.1 mm; ground color grayish brown; subcostal band undifferentiated; basal dash thick, black, extending from wing base to beyond claviform spot, not reaching wing outer margin; basal line undifferentiated; antemedial line undifferentiated; claviform spot dark brownish and black edged; orbicular spot oval, light grayish brown with grayish center and black edged; reniform spot concolorous with orbicular spot, distal margin with one or two sharp streaks extending between M1–M2–M3 veins to postmedial line; discal cell dark brown; medial line undifferentiated; postmedial line undifferentiated; subterminal line light brown black-edged arrows between veins, arrows between M1–M2–M3 veins extending to postmedial line, first arrow contiguous with reniform streak like one continuous line; terminal line black; fringe concolorous with forewing ground color with light brown basal line. Hind wing dark brown diffuse to wing base; fringe whitish, with light brown medial line. Abdomen . Grayish brown. Genitalia ( Fig. 60 ). Uncus sinuous. Clavus barely differentiated as an area of piliform setae. Ampulla 1/5 × as long as valve, basal 1/4 expanded, then narrows to 1/3 its widest diameter. Aedeagus not examined. Female . Differences from male. Forewing length: 16.7 mm; antenna filiform. Genitalia . Not examined. Distribution. Restricted to Túcuman province, Argentina ( Fig. 108 ). Remarks. Specimens examined are poorly preserved, characters as patagium and tegulum may vary on better preserved specimens. Male genitalia description is based on a slide made by Köhler, where aedeagus was lacking. Male specimens cited under examined material were dissected by Köhler and slides are not at IMLA. Material examined. ( 2 ♂ ) ARGENTINA . Tucumán. Tafí, San José, 2500m , ♂ IV-1933 (Schreiter) ( IMLA ); Cerro de la Mina, 3000m , ♂ IV-1933 ( IMLA ).
