Magnana, a new genus of Gyponini from Southeastern Brazil (Hemiptera: Cicadellidae: Iassinae)

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.

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

“…The New World tribe Gyponini Stål, 1870 is the largest of the 12 tribes of Iassinae Walker, 1870, currently comprising 1,448 described species classified into 75 genera. To date, 347 species and 42 genera are known to occur in Brazil (Domahovski & Cavichioli, 2021, 2022Domahovski, 2021;Gonçalves et al, 2021, Laranjeira et al, 2022, Silva et al, 2022Takiya et al, 2022. These leafhoppers can be collected by sweeping shrubs, trees, grasses or herbaceous vegetation in the understory.…”
