A new leafhopper (Hemiptera: Cicadellidae) from late Eocene Rovno amber described based on an adult and associated last-instar nymph from Perebrody (Ukraine)

Abstract

Rovnoxestus rasnitsyni gen. & sp. nov. is described from Eocene Rovno amber based on an adult female and fifth-instar nymph collected at a recently discovered locality at Perebrody, Rovno Province, Ukraine. The new fossil taxon is tentatively placed in Aphrodinae and resembles Xestocephalites Dietrich & Gonçalves from Eocene Baltic amber but has the hind femur macrosetal formula 2+2+1 and hind tarsomere I in both nymph and adult with an elongated inner preapical seta. This is the first species of Eocene leafhopper for which both the adult and nymph are described in detail.
