Diagnosis. Agrotis propriens differs from other South American species of Agrotis by the following combination of characters: 1) forewing basal dash black, extending from wing base to base of claviform spot; 2) antemedial and postmedial lines black, double; 3) subterminal line light brown and black edged, extended basally as arrows, longest ones placed between M1–M2–M3 veins; 4) in male genitalia vesica 6 × as long as aedeagus; and 6) right basal diverticulum and basal spined band present.

Redescription. Male ( Fig. 8 ). Head. Palpus whitish ventrally; frons central projection with raised edge of rough surface, not projected anteriorly into a point. Antenna bipectinate, widest at 1/3 its length, gradually tapering to apex, widest segment 3 × as wide as central shaft, anterior process 1.5 × as wide as posterior process. Thorax. Patagium slightly darker than thorax, with black medial line and diffuse brown marginal line; tegulum without differentiated lines. Forewing length 15.2–15.9 mm; ground color light brown; subcostal band undifferentiated; basal dash black, extending from wing base to base of claviform spot; basal line undifferentiated; antemedial line black, double, convex between veins, strongly extended as a sharp tooth between 1A+2A vein and posterior margin, not differentiated in light specimens; claviform spot wide, dark grayish brown and black edged; orbicular spot strongly oval, extending toward the reniform spot, never contiguous with the latter, concolorous with ground color, black edged with dark grayish brown center; reniform spot concolorous with orbicular spot, with a streak extending between M1–M2 veins to subterminal line; discal cell dark grayish brown; medial line undifferentiated; postmedial line black, double, concave between veins; subterminal line light brown and black edged, strongly concave between veins, extended basally as arrows, longest ones between M1–M2–M3 veins, in some specimens first arrow joined with reniform streak like one continuous line; terminal line a series of darkish lunulae between veins; fringe light brown with darker medial and marginal lines. Hind wing iridescent with diffuse light brown margins, or diffuse light brown; fringe iridescent, with light brown medial line. Abdomen. Concolorous with forewing ground color. Genitalia ( Fig. 47 ). Clavus barely differentiated as an area of piliform setae. Ampulla 1/5 × as long as valve, basal 1/3 expanded, then narrowed to half its widest diameter; saccus subtriangular. Vesica ( Fig. 65 ) 6 × as long as aedeagus, consisting of 1 1/2 wide loop, right basal diverticulum subtriangular, basal spined band present. Female. Differences from male. Forewing length: 14.8 mm; antenna filiform; forewing and hind wing slightly darker than males. Genitalia. Posterior apophysis as long as anterior apophysis; ductus bursae 1.5 × as long as anterior apophysis; corpus bursae 3 × as long as anterior apophysis, signum absent, apex subtriangular.

Distribution. Restricted to the southern part of Peru ( Fig. 95 ).

Material examined. (4 ♂). PERU: Cuzco. Cuzco, 3800m, 4 ♂ 14-IX-1963 ( IMLA).
