A new species, Ischnodemus brusai, from Ucayali, Peru is described and illustrated, including characters of the male genitalia. Adult males and females, and immature specimens of I. subflavus Slater and Wilcox 1969 were collected on Sporobolus rigens (Trinius) Desvaux (Poaceae) in the province of Chubut, Argentina. This is the first record of the male for this species. Descriptions and illustrations of a male individual, as well as male and female genitalia and immature stages II to V are provided. Affinities with other Neotropical species of Ischnodemus are discussed.
