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.
