A new species of Marganana (Declivana) (Hemiptera: Cicadellidae: Gyponini), the first record of the genus from Brazil

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.(AU)
