Extension of the leafhopper genus Multinervis (Hemiptera, Cicadellidae, Megophthalminae, Agalliini) from Northern to Central Vietnam, with the description of one new species

Abstract

A new species of the genus Multinervis Li & Li, 2013, Multinervis phongdienensis sp. nov., is described from two locations in Central Vietnam, Thưa Thien-Hue Province: Bach Ma National Park and Phong Dien District. It represents a second species for the genus and for the fauna of Vietnam, where the type species, M. guangxiensis Li & Li, 2013, has also previously been recorded from Northern Vietnam. Illustrations, a differential diagnosis to distinguish the two Multinervis species and a distribution map are provided. Multinervis phongdienensis sp. nov. is characterized by the absence of forewing crossveins in the claval region, the reduced subgenital plates being almost entirely fused, the absence of a subgenital angular projection and the unusual lateral flanges of the male connective.
