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.

Eight new species of Costanana DeLong & Freytag (Hemiptera: Cicadellidae: Gyponini): taxonomic changes, key to males, and description of Metacostana gen. nov.

“…Gyponini Stål, 1870, the most diverse of the twelve tribes of Iassinae Walker, 1870, currently comprise about 1465 species in 79 genera, but with an expectation of easily surpassing 2000 species (Gonçalves et al 2021;Silva et al 2022;Domahovski & Cavichioli 2022a, 2022b, 2022c, 2023Laranjeira et al 2022). This tribe is restricted to the New World, with a distribution of approximately 18%, 19.3% and 63.6% of the species in North, Central and South America, respectively, and 20, 30 and 73 genera recorded for each Continent, respectively.…”
