The planthopper genus Neometopina Yang (Hemiptera: Fulgoroidea: Delphacidae: Delphacinae: Delphacini) is revised to include 2 species: Neometopina penghuensis Yang, 1989 (China: Guizhou: Maolan), and Neometopina orientalis (Qin & Zhang) comb. n. (China: Hainan: Bawangling) (transferred from Laminatopina Qin & Zhang). The included species are described and illustrated, and a key to species is pr...

The number of species of planthoppers (excluding Delphacidae) known from Delaware is updated from 7 (in 4 families) to 62 species (in 9 families). Specimen abundance is tallied by county and seasonally by two week intervals. The Chao1 abundance estimator suggests that the true fauna may be 74 species, although species incidence tallied from adjacent states (MD, NJ, PA and DC) suggests that a to...

The planthopper superfamily Fulgoroidea (Insecta: Hemiptera) is one of the most dominant groups of phytophagous insects. It comprises about 20 families, containing a total of 9000 species worldwide. Despite several recent studies, the phylogeny of Fulgoroidea is not yet satisfactorily resolved and the phylogenetic positions of several key families, especially Cixiidae, Delphacidae, Tettigometri...

This report is concerned primarily with the family Issidae as represented m the Lesser Antilles, but opportimity has been taken to comment on a few species of interest from other parts of the Caribbean area. The material on which this study has been based, with only one or two exceptions, was collected by the writer. Holotype and allotype specimens of new species described have been deposited i...

In the framework of the recent expedition results of "Our Planet Reviewed Papua-New-Guinea 2012-2013" we provide here the first Issidae (Hemiptera, Fulgoroidea) fauna review of New Guinea with the description of three new taxa: one new genus Papunega Gnezdilov et Bourgoin gen. nov. with two new species: Papunega magnifacies Gnezdilov et Le Cesne, sp. nov. (type species), Papunega armocula Gnezd...

Abstract Acanalonia conica (Say, 1830), the first representative of Nearctic planthopper family Acanaloniidae (Hemiptera: Auchenorrhyncha: Fulgoroidea), introduced to Europe, is reported for time from multiple locations in Hungary. Diagnosis, detailed illustration male genitalia and notes on ecology are provided along with distributional records.

An updated list of Issidae known from Vietnam is provided. Two new species, one from the genus Darwallia Gnezdilov, 2010, and another one from a new genus are described from the Hòn Bà massif in Central Vietnam. A key to species of the genus Darwallia is provided. Gelastyrella hainanensis Ran et Liang, 2006 is placed in synonymy under Thabena litaoensis Yang, 1994. This last taxon and the genus...

The planthopper genus Neohemisphaerius Chen, Zhang & Chang, 2014 (Hemiptera: Fulgoroidea: Issidae) is reviewed to include 3 species: Neohemisphaerius wugangensis Chen, Zhang & Chang, 2014 (China: Hunan), Neohemisphaerius yangi Chen, Zhang & Chang, 2014 (China: Guangdong) and Neohemisphaerius guangxiensis sp. n. (China: Guangxi). A revised generic diagnosis is given. The new species is described...
