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 M 1 –M 2 –M 3 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 1 A+ 2 A 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 M 1 –M 2 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 M 1 –M 2 –M 3 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).
