Rubiparvus bistigma, a new genus and species of Empoascini (Hemiptera, Cicadellidae, Typhlocybinae), with a checklist of the Alebroides group in Chinese fauna

Abstract

A new leafhopper genus of the tribe Empoascini, Rubiparvus gen. nov., is described based on Rubiparvus bistigma sp. nov. from Yunnan (southwest China). Habitus photos and illustrations of male genitalia of this new species are given. Differences between the new genus and closely related genera are discussed. A checklist of the Alebroides generic group in the Chinese fauna is provided.

Two new leafhopper genera of the Alebroides genus group (Hemiptera: Cicadellidae: Typhlocybinae) from China, with a key to genera of the group

“…Rubiparvus Xu, Dietrich & Qin in Xu et al , : 584. Type species: Rubiparvus bistigma Xu, Dietrich & Qin, 2016…”

“…It can be distinguished from other tribes of Typhlocybinae as follows: ocelli usually well developed; forewing without appendix; hind wing submarginal vein extended between apices of veins MP’ or RP + MP’ and MP” + CuA’; male anal tube usually with pair of processes at base; male paramere without preapical lobe; male subgenital plate usually with numerous macrosetae (Qin et al ). Genera of this tribe have been divided into two informal groups, the Alebroides group and the Empoasca complex (Young ; Xu et al ). Members of the Alebroides group have hind wing vein CuA branched, while members of the Empoasca complex have this vein unbranched.…”

“…The taxonomy of the Empoasca complex seems rather complicated and the status or diagnoses of many known taxa need reclarification (especially in the cosmopolitan genus Empoasca Walsh, 1862). In contrast, the Alebroides group appears more stable in classification, comprising 156 species in 25 genera so far, widely distributed in the Oriental, Palaearctic, Afrotropical and Australian Regions but absent from the New World (Xu et al ).…”

A new leafhopper genus of Empoascini (Hemiptera, Cicadellidae, Typhlocybinae) from China

“…The Alebroides group of Empoascini leafhoppers includes 25 genera and 156 species, widely distributed in the Palaearctic Region and Old World tropics (Xu et al 2016). Of these taxa, 16 genera and 60 species are known from China (Xu et al 2016, Yu and Yang 2013, 2014a. A key to the group, characterized by the branched CuA vein in the hind wing ( Fig.…”

Condensella and Endogena, two new genera of the Alebroides genus group (Hemiptera: Cicadellidae: Typhlocybinae) from the Oriental Region with notes on the phylogeny of Empoascini

“…Knowledge of the world fauna of Empoascini remains incomplete and new genera and species continue to be discovered at a rapid pace. Members of this tribe have been assigned to three informal generic groups (Qin et al, 2011;Xu et al, 2015Xu et al, , 2016, one of which, the Alebroides group, is characterized by the vein CuA in the hind wing branched preapically. The Alebroides group comprises 158 species in 27 genera so far, widely distributed in the Old World (Xu et al, 2017).…”
