Diagnosis. Agrotis leucovenata differs from other South American species of Agrotis by the following combination of characters: 1) male antenna bipectinate, widest segment 6 × as wide as central shaft; 2) forewing veins strongly whitish; 3) basal and antemedial lines black, single, basally edged by a light brown shade; 4) in male genitalia vesica 4–5 × as long as aedeagus; 4) right basal diverticulum absent, and 5) in female genitalia appendix bursae less than 2 × as long as corpus bursae.

Redescription. Male ( Figs 26 , 55 , 73 ). Forewing length 10.8–15.5 mm. Female ( Figs 27 , 86 ). Forewing length 12–15.5 mm. (see San Blas & Gentili, 2011: 93–97).

Distribution. Restricted to Neuquén province, Argentina ( Fig. 103 ).

Discussion. Agrotis leucovenata is similar to A. elegans and A. edmondsi . Forewing veins strongly whitish and antenna strongly bipectinate in males allowing quick differentiation of this species. Distinct genitalic characters include the male vesica with no basal diverticulum and female appendix bursae less than 2 × as long as corpus bursae.
