Abstract
Marganana DeLong, 1948 currently includes three species known to occur in the United States, Mexico and Guyana. In this paper, we describe a new species from Brazil - Marganana (Declivana) tetramaculata sp. nov. - which represents the first record of this genus for the country. A revised diagnosis of the subgenus Declivana is provided, along with detailed descriptions and illustrations of males and females of the new species. A key to the four species of Marganana is also provided.
