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 splendidagen. 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.(AU)
