(Figs 11, 12, 49, 67, 97)
Agrotis dispar Köhler, (1958)1959: 52; Köhler, 1967: 331, figs 66, 67; Poole, 1989: 47. Syntypes: ♂ ♀ Bolivia, Oruro, 3700m (W. Wittmer) (IMLA); ♂ (W. Wittmer) (ZSM). Note: Köhler ((1958)1959) designates holotype, allotype, and paratypes for this species, but at IMLA and ZSM collections only cotypes were found. In Köhler’s (1967) catalog there are two photos of female specimens labeled as “Cotype.” Possibly Köhler never labeled the specimens he designated in the species description.
Diagnosis. Agrotis dispar 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) forewing basal dash extending from wing base to beyond claviform spot, not reaching wing outer margin; 3) reniform spot shaped like a horizontal “ Y;” 4) basal, antemedial, postmedial, and subterminal lines undifferentiated; 5) in male genitalia ampulla 1/5 × as long as valve; and 6) basal spined band absent.
Redescription. Male (Fig. 11). Head. Palpus whitish ventrally; frons smooth, central projection and raised edge absent. Antenna bipectinate, widest at 1/5 its length, gradually tapering to apex, widest segment 3 × as wide as central shaft, anterior process 2 × as wide as posterior process. Thorax. Patagium with a black medial line; tegulum with a black marginal line. Forewing length 14 mm; ground color light brown; subcostal band undifferentiated; basal dash thick, brown, from wing base to beyond claviform spot, not reaching wing outer margin; basal line undifferentiated; antemedial line undifferentiated; claviform spot slightly differentiated, dark brown; orbicular spot slightly oval, light brown, black edged with grayish center; reniform spot concolorous with orbicular spot, shaped like a horizontal “ Y;” discal cell brown; medial line undifferentiated; postmedial line undifferentiated; subterminal line undifferentiated; terminal line a series of darkish lunulae between veins; fringe concolorous with forewing ground color. Hind wing iridescent; discal spot blackish; fringe iridescent. Abdomen. Light brown. Genitalia (Fig. 49). Clavus slightly sclerotized, cylindrical, short, 2 × as long as wide. Ampulla 1/5 × as long as valve, basal 1/3 expanded, then narrowed to 1/3 its widest diameter; saccus subtriangular. Vesica (Fig. 67) 4 × as long as aedeagus, consisting of 1 1/2 wide loop, right basal diverticulum subtriangular, basal spined band absent. Female (Fig. 12). Differences from male. Forewing length: 9.2 mm; antenna filiform; forewing ground color slightly darker than male; hind wing diffuse brown, with slightly darker discal spot and postmedial band. Genitalia. Not examined.
Remarks. Köhler ((1958)1959) describes wing span in males as 28–40 mm and in females as 17–25 mm. These measurements could not be checked because of unavailability of more material to examine.
Distribution. Restricted to type locality of Oruro, Bolivia (Fig. 97).
