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.
