A new viral pathogen of the glassy-winged sharpshooter, GWSS, (Homalodisca vitripennis, aka H. coagulata) was discovered and characterized. Few pathogens of leafhoppers have been discovered which have potential for use as a biological control agent. To identify new pathogens of GWSS we used a genomic approach to isolate, sequence, and identify expressed sequence tags, ESTs, produced from field ...

Two new species of the Macropsinae leafhopper subgenus Pediopsoides (Pediopsoides) Matsumura, 1912, Pediopsoides (Pediopsoides) damingshanensis Li, Dai & Li, sp. n. and Pediopsoides (Pediopsoides) tishetshkini Li, Dai & Li sp. n., are described and illustrated from Guangxi Province of southern China. A key to males is provided to distinguish the species of the subgenus along with a map showing ...

A previously unknown species of the North American leafhopper genus Flexamia, Flexamiawhitcombi sp. n., is described from pinebarren smokegrass (Muhlenbergiatorreyana (Schult.) Hitchc.), a state-listed threatened grass in the New Jersey Pine Barrens. The serrata species group, to which it belongs, is redefined and a key to the species of the group is provided. This is the first reported insect ...

Tardrabassus pakneunensis, n. gen. & sp. is described and illustrated. The new genus shows morphological affinities to three leafhopper subfamilies, Tartessinae, Deltocephalinae, and Iassinae, but is tentatively placed in Iassinae based on the position of the ocelli, the reduced lateral frontal sutures, the leg chaetotaxy, and the structure of the male genitalia.

A novel iflavirus was discovered from the transcriptome of the leafhopper Graminella nigrifrons. The assembled virus genome has 9,700 nucleotides (nt) and encodes a 3,035-amino-acid polyprotein. Sanger sequencing was used to confirm the sequence encoding the polyprotein and indicated a genome length of 9,617 nt with a polyadenylated tail.

The South American leafhopper genus Parandanus Linnavuori & DeLong (Deltocephalinae: Deltocephalini) is reviewed and four of its six species are illustrated and male genital characters are provided. Three new species from Peru, Parandanus longistylus Duan, sp. n., Parandanus nigricephalus Duan, sp. n. and Parandanus paracruciatus Duan, sp. n. are described. A key to species is also provided.

The Chinese mainland species of the leafhopper genus Nephotettix Matsumura (Hemiptera: Cicadellidae: Deltocephalinae: Chiasmini) (Nephotettix cincticeps (Uhler), Nephotettix malayanus Ishihara & Kawase, Nephotettix nigropictus (Stål), Nephotettix parvus Ishihara & Kawase rec. n., and Nephotettix virescens (Distant)) are reviewed. This genus is redescribed. Variation is described and illustrated...

Bambusananus cuihuashanensis sp. n. (Hemiptera: Cicadellidae: Deltocephalinae: Athysanini), a new bamboo-feeding leafhopper species, is described and illustrated from Shaanxi Province of China. Checklist, host plants and distribution for each species of Bambusananus is given along with a key to all known species.

Four new species of the empoascine leafhopper genus Alebroides Matsumura are reported from China: A. strumae Yu & Yang, sp. nov., A. chiasmaticus Yu & Yang, sp. nov., A. serrulatus Yu & Yang, sp. nov. and A. spanner Yu & Yang, sp. nov. A list of all Chinese species of the genus is provided.
