Richness of the Nearctic Treehopper Fauna (Hemiptera: Aetalionidae and Membracidae)
The indigenous Nearctic treehopper fauna includes 2 families, 6 subfamilies, 20 tribes, 68–72 genera, and 276–280 de-scribed species, of which 1 tribe, 16 genera, and 195 species are endemic. This work provides an alphabetical checklist of the species (with distributions as documented in the literature) as well as discussions and two tables summarizing the tax-onomic and regional diversity of this rich, distinctive fauna. The tribes Smiliini and Telamonini (Membracidae: Smilii-nae), which include many specialists on oaks (Quercus spp.), are the two most species-rich tribes. Maps of the Nearctic subregions document the species richness of each state and province, 22 of which have between 60 and 118 reported spe-cies. The Southwest U.S. has the largest number of genera of the subregions, while both the Southwest and the Central and Eastern U.S. are highly species rich. Arizona stands apart as an area of exceptional endemism with one genus and 25 species known only from within its bord...
Treehopper Diversity (Hemiptera: Membracidae) of Little Orleans, Allegany Co., Maryland
Proceedings of the Entomological Society of Washington, 2008
Fifty-six species (23 genera) of treehoppers (Membracidae) are recorded from the vicinity of Little Orleans, Maryland, with date and host-plant data. Eleven of the species represent new state records for Maryland, bringing the total number of species recorded for the state to 81. These data document annual collecting efforts since 1993 by the authors and others in connection with the informal treehopper conferences initiated by the late T. K. Wood. Photographs are given for 12 species representing 7 genera.

The hypsoprorine treehopper Philya ferruginosa (Goding), described from Arizona in 1894, has remained little known. Images of Philya posted recently on the internet represent misidentifications of the Neotropical P. lowryi Plummer, known only from the type locality in south-central Mexico; the records refer to P. ferruginosa. The nymphs and adults of P. ferruginosa we found on New Mexico locust (Robinia neomexicana A. Gray; Fabaceae) in southeastern Arizona are the first host records for the treehopper. We differentiate P. ferruginosa from its native congener P. californensis (Goding) and the Mexican P. lowryi, describe the fifth-instar nymph of P. ferruginosa, and present new records from Madrean Sky Island localities in Arizona. We regard as incidental the collection of adults from plants that seem unlikely to support nymphal development.

Dysyncritus Fowler is revised based on the examination of primary types, and restructured to exclusively accomodate Dysyncritus intectus Fowler, 1895. Allodrilus Evangelista gen. nov. (type species: Cymbomorpha nitidipennis Funkhouser, 1922 = Allodrilus nitidipennis (Funkhouser, 1922) comb. nov.) is erected with seven newly discovered taxa: A. alboferrugineus Evangelista sp. nov. (Brazil, Colombia, Guyana), A. colombiensis Flórez-V sp. nov. (Colombia), A. deitzi Evangelista sp. nov. (Ecuador), A. granulatus Evangelista sp. nov. (Ecuador), A. horizontalis Evangelista sp. nov. (Bolivia), A. intermedius Evangelista sp. nov. (Ecuador), and A. similis Evangelista sp. nov. (Peru). A key to males is provided, in addition to annotated descriptions and illustrations. Nomenclatural changes are proposed to species formerly included in Dysyncritus:

Three new genera in Acutalini are described, two of which have two discoidal cells (R2+3 and M) in the forewing, as in Euritea Stål. Ceresinoidea zackigen. nov. et sp. nov., from Guatemala, differs from other acutalines in having a pair of suprahumeral spines and a stepwise convex pronotum in lateral view. Quinquespinosa septamaculagen. nov. et sp. nov., which is widely distributed in South America, differs in having a basal cell M and three posterior pronotal spines. Tectiforma guayasensisgen. nov. et sp. nov., from Ecuador, has the pronotum strongly tectiform throughout. A key to all genera of Acutalini is provided.
Three new genera in Acutalini are described, all of which have two discoidal cells (R2+3 and M) in the forewing, as in Euritea Stål. Osaria quadrilinea n. gen. et n. sp. differs from other acutalines in having a pair of suprahumeral spines and a strongly convex pronotum in lateral view. It differs from O. zacki, n. sp., in having an evenly convex, rather than stepwise convex pronotum in lateral view, in addition to other details. Quinquespinosa septamacula n. gen. et n. sp. differs in having three posterior pronotal spines. Tectiforma guayasensis n. gen. et n. sp. has the pronotum strongly tectiform throughout. //add distro gf geera A key to all genera of Acutalini is provided
The immatures stages of 8 of the 11 genera (Amastris Stål, Bajulata Ball, Erosne Stål, Harmonides Kirkaldy, Idioderma Van Duzee, Neotynelia Creão-Duarte & Sakakibara, Tynelia Stål, and Vanduzea Goding) of the tribe Amastrini are described for the first time along with brief diagnoses of Membracidae and the subfamily Smiliinae. A key to genera and notes on biology are provided. Multiple species of most genera are illustrated. Based on its distinct nymphal morphology, Vanduzea laeta nolina Ball is elevated to specific rank as Vanduzea nolina stat. n., and Bajulata, despite the superficial similarity of its adults to those of Vanduzea, is confirmed as warranting generic rank based on its unique nymphal morphology. Colombia is a new country record for Tynelia.
Two new species of Darnini (Hemiptera: Membracidae) from Colombia and Peru
Zootaxa, 2017
Two new species of treehoppers (Hemiptera: Membracidae) from Colombia and Peru are described. Cyphotes colombiensis sp. nov. and Hypheodana sakakibarai sp. nov. both belong in the tribe Darnini. New distribution records are provided for Cyphotes (from Colombia) and Hypheodana (from Peru).
