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

Abstract

Two new microleafhopper genera in the Alebroides genus group, Nulliata Lu, Xu & Qin, gen. nov., based on the type species N. rubrostriata Lu, Xu & Qin, sp. nov., and Inflatopina Lu, Dietrich & Qin, gen. nov., based on the type species I. intonsa Lu, Dietrich & Qin, sp. nov., are described from southwest China. Five known species in the Alebroides sohii species group are transferred to Inflatopina as new combinations. Keys to genera of the Alebroides genus group and species of Inflatopina are given.

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

“…One of them is the Alebroides group characterized by a branched vein CuA in the hind wing and including 27 genera, widely distributed in the Oriental, Palaearctic, Afrotropical and Australian Regions but absent in the New World (Xu et al, 2017). The second is the Ficiana group comprising seven genera (Ficiana Ghauri, 1963;Ishiharella Dworakowska, 1970b;Dialecticopteryx Kirkaldy, 1907;Mahmoodia Dwora kowska, 1970a;Nimabanana Dworakowska, 1994b;Kotwaria Dworakowska, 1984 andDaluana Ram akrishnan, 1982) defi ned by having hind wing vein CuA unbranched, the male subgenital plates fused, the ventral pygofer appendage lacking and three apical veins in the fore wing arising from cell m (Xu et al, 2015).…”

“…It comprises 89 previously described genera and more than 1000 species worldwide (Xu et al, 2017), including widespread, polyphagous agricultural pests such as the Potato Leafhopper, Empoasca fabae (Harris) (Chasen et al, 2014) and Cotton Leafhopper Amrasca biguttula biguttula (Ishida) (Saeed et al, 2015), as well as pests that appear to be monophagous on one particular crop, such as the Tea Green Leafhopper, Empoasca onukii Matsuda (Qin et al, 2015). 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).…”

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

“…Habitus photos were taken using a VHX-5000 digital microscope; illustrations of male genitalia were inked in Adobe Illustrator CS6, then digitized (300dpi). For morphological terminology we mostly follow Zhang (1990), but the wing venation follows Dworakowska (1993), the legs follow Dietrich (2005) and chaetotaxy of the subgenital plate follows Southern (1982) Xu et al (2017), based on the following characters (in order of couplets): MP' vein arising from r cell, coronal suture not extending onto face, anal tube appendage absent, crown face transition without a dark medial patch and male pygofer not emarginated dorsally, aedeagus with preatrium long. The new genus differs from Nulliata in having the abdominal apodemes long and from Nulliata and other genera in having a finger-like process bearing micro-setae on the lower posterior margin of the male pygofer.…”

“…A key to the group, characterized by the branched CuA vein in the hind wing ( Fig. 13), was given by Xu et al (2017). This paper adds a new genus with one new species, based on material from Guizhou (Southwest China).…”
