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.

Abstract A new leafhopper genus in the tribe Gyponini is proposed based on Magnana splendida gen. nov. et sp. nov., from the state of Rio de Janeiro, Brazil. Representatives of the new genus differ from other genera in the tribe mainly by the large body size, the narrow head, moderately produced anterad, the rugose crown and frons, the ventral surface of metatarsomere I with two double rows of setae, and the aedeagus bearing atrial processes. Detailed descriptions and illustrations are provided, as well as remarks on the morphology of other gyponine genera.
