According to 45.6.4 ICZN article: “it is subspecific if first published before 1961 and its author expressly used one of the terms "variety" or "form" (including use of the terms "var.,” "forma,” "v." and "f."), unless its author also expressly gave it infrasubspecific rank, or the content of the work unambiguously reveals that the name was proposed for an infrasubspecific entity, in which case it is infrasubspecific.” As mentioned before, and because there is no evidence that Aurivillius, Prout, and Meyrick (1922) have referred to this taxon as lower in rank than subspecies, I consider it a subspecies and subjective junior synonym of Agrotis malefida .

Cited materials correspond to specimens at IMLA, no material was found at ZSM. Despite cited material does not fully agree with the data given in the description, these specimens are maintained as types because part of the information does agree and they are conspecific with Scotia (Feltia) canietensis . Agrotis canietensis (Köhler) : Poole, 1989 : 45 (new combination); Pastrana, 2004 : 15 (hosts). Diagnosis. Agrotis malefida differs from other South American species of Agrotis by the following combination of characters: 1) patagium basal half dark brownish gray and distal half dark gray; 2) forewing length in males 19.5– 20.9 mm, in females 18.8–21.1 mm; 3) ground color whitish to dark grayish brown; 4) subterminal line light brown; 5) in male genitalia vesica 10 × as long as aedeagus; and 6) in female genitalia appendix bursae 14 × as long as corpus bursae. Redescription. Male ( Fig. 32 ). Head . Frons central projection small, with raised edge of rough surface, projected anteriorly into a point, some specimens with no projection. Antenna biserrate, widest at 1/5 its length, gradually tapering to apex, widest segment 2 × as wide as central shaft, anterior process 2 × as wide as posterior process. Thorax . Patagium with whitish postbasal line and blackish medial line, basal half dark brownish gray and distal half dark gray; tegulum light gray, with blackish basal and marginal lines, later widened anteriorly. Forewing length 19.5–20.9 mm; ground color whitish to dark grayish brown; subcostal band dark grayish brown; basal area darker than ground color; basal line black, double; antemedial line black, double, convex between veins, extended as a sharp tooth between 1A+2A vein and posterior margin, in some specimens it coming near 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; subterminal line light brown, concave between veins, extending basally as small light arrows, longest ones between M1–M2–M3 veins, black edged basally, arrows never contiguous with postmedial line; terminal line a series of darkish lunulae between veins; fringe concolorous with ground color with dark transversal lines at apex of veins. Hind wing iridescent, in dark specimens wing margins diffuse brown; fringe iridescent. Abdomen . Light grayish brown, with dark dorsal line. Genitalia ( Fig. 58 ). 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. 76 ) 10 × as long as aedeagus, consisting of six wide loops, right basal diverticulum subtriangular, vesica slightly swollen on apical 1/5. Female ( Fig. 33 ). Differences from male. Forewing length: 18.8–21.1 mm; antenna filiform; ground color dark grayish; hind wing with dark brown veins, anal and apical margins diffuse dark brown. Genitalia ( Fig. 89 ). Posterior apophysis 2 × 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 14 × as long as corpus bursae, consisting of six wide loops, apex globose; ductus seminalis originating laterally near corpus bursae apex. Variation. Specimens from Brazil are much lighter than the others, with color pattern very diffuse. Claviform and orbicular spots almost undifferentiated and transverse lines not well defined. Immature stages and hosts. Crumb (1956) makes a detailed description of all stages and biology of this species, Hampson (1903) , Forbes (1954) , Crumb (1956) , Godfrey (1987) , and Lafontaine (2004) make a larval diagnosis. Chiesa Molinari (1942) , Hayward (1969) , and Pastrana (2004) (as A. psammophila and A. canietensis ) make lists of economically important host species. Distribution.

Köhler (1961) describes A. psammophila based on dark specimens collected at San Rafael, Mendoza, Argentina . Nevertheless, those specimens have the same thoracic lines, forewing lines, spot pattern, and genitalia of both sexes are identical to A. malefida . Founded on these similarities, I decide to synonymize the species. Hampson (1903) describes Lycophotia achromatica with three male specimens from Bahia, Brazil . These specimens have forewing ground color whitish with diffuse spots and transverse lines. Adults share with A. malefida the patagium and tegulum color patterns and male genitalic characters. Based on these resemblances, I decide to synonymize the species.
