A remarkable new species of the sharpshooter genus Egidemia (Insecta, Hemiptera, Cicadellidae, Cicadellinae)

A new species of Egidemia China, 1927, Egidemia impudica, is described and illustrated from the Department of Magdalena (Colombia). The male genitalia of the new species have a very peculiar, diagnostic feature: the pygofer is considerably reduced and truncate posteriorly, so that part of the aedeagus is exposed. A key to males of all known Egidemia species is provided. Notes comparing Egidemia impudica with the other nine known species of the genus are also given.     

Phylogenetic analysis of the sharpshooter genus Subrasaca Young, 1977 (Hemiptera,Cicadellidae, Cicadellini)

The South American sharpshooter genus Subrasaca comprises 14 species. Some species of this genus are quite common in the Brazilian Atlantic Rainforest. In this paper, a phylogenetic analysis of Subrasaca, based on a matrix of 20 terminal taxa and 72 morphological characters of the head, thorax, and male and female genitalia, is presented. The analysis yielded six equally most parsimonious trees (197 steps, CI = 0.6091, RI = 0.5722, and RC = 0.3486). The results suggest that Subrasaca is a monophyletic taxon, although the genus branch is not robust. The clade showing the highest bootstrap and Bremer scores is formed by species with longitudinal dark brown to black stripes on the forewings (Subrasaca bimaculata, Subrasaca constricta, Subrasaca curvovittata, and Subrasaca flavolineata), followed by Subrasaca atronasa + Subrasaca austera.     

A remarkable new genus of leafhoppers (Hemiptera,Cicadellidae, Iassinae) from Southeast Asia

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 new species of the sharpshooter genus Onega Distant, 1908 (Hemiptera: Cicadellidae: Cicadellini) from Ecuador and Peru

Onega comprises nine valid species distributed in South American countries, Bolivia, Colombia, Ecuador, Paraguay and Peru, commonly at high altitudes. The genus has as diagnostic characteristics the transition crown-frons with transversal carina; crown and superior portion of frons with concavities; pronotum wider than transocular width of head; and paraphysis, when present, as a median esclerite. The present paper describes Onega musa sp. nov., from Ecuador and Peru, which can be distinguished from other Onega species by: body mostly yellow, with brown maculae distributed on dorsum; posterior margin of male pygofer serrate, with long microsetae on the basiventral margin; aedeagus with shaft bisinuate with dorsal acute preapical process; female sternite VII with posterior margin slightly convex; and first valvula of ovipositor with 38 noncontiguous teeth. Intraspecific morphological variations are discussed.

A new species and new records of the leafhopper genus Taperus Li & Wang, 1994 (Hemiptera,Cicadellidae, Evacanthinae) from China

The paper deals with the species of the Oriental leafhopper genus Taperus Li & Wang. A new species, Taperus daozhenensissp. n., from Guizhou Province, China is described and new records for other Chinese species are given together with a key for their separation. The type specimens of the new species are deposited in the Institute of Entomology, Guizhou University (GUGC).     

Descriptions of a new Brazilian Tacora species and the female of Tacora saturata, and a key to the species of the genus (Insecta, Hemiptera, Cicadellidae, Cicadellini)

Tacora johanni, a new species from Rondônia State, North Brazil, is described and illustrated. The new species can be recognized by the male genital features, especially the subgenital plates with the basal half distinctly expanded and with outer lateral margin round, the long and slender preapical pygofer process, and the styles with apical half strongly curved. Also, the genus is recorded for the first time from Venezuela, based on specimens of Tacora saturata Young, 1977, while the female of this species (here described in detail for the first time) shows two unusual features of the genitalia. A key to males of all known Tacora species and a map showing the known distribution of the genus are provided.     

Two new species of the genus Abrus Dai & Zhang, 2002 (Hemiptera,Cicadellidae, Deltocephalinae) from China

Two new species of leafhoppers: Abrus damingshanensissp. n. (from Guangxi) and A. expansivussp. n. (from Guizhou) are described and illustrated from China. A map showing the geographic distribution of the two new species is given. Taxonomic notes on species of the genus Abrus is also provided.     

Description of two new species of the leafhopper subgenus Pediopsoides (Pediopsoides) (Hemiptera,Cicadellidae, Macropsinae) from Guangxi Province,Southern China

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 the distribution of the new species.     

A new genus and species in the tribe Empoascini (Hemiptera,Cicadellidae, Typhlocybinae) from China

One new leafhopper genus, Circinans, is described with a new species Circinans striata sp. n. as the type species from southern China. Habitus photos and illustrations of male genitalia of this new species are given and differences between the new genus and closely related genera are discussed.     

A remarkable new opsiine leafhopper genus (Hemiptera: Cicadellidae: Deltocephalinae) from Southern China,with notes on its phylogenetic position

A remarkable new genus of tribe Opsiini (Deltocephalinae), Yinformibus gen. nov. including Yinformibus menglaensis sp. nov. is described from Yunnan of China. The new genus is placed in the tribe Opsiini based on male adults having a pair of aedeagal shafts, each with its own gonopore. Partial 28S rDNA and Histone H3 sequences are provided for the new species, and a phylogenetic analysis based on these markers for Deltocephalinae retrieved from GenBank suggests Opsiini is monophyletic and supports the placement of Yinformibus gen. nov. in Opsiini. The molecular results placed the new genus in a clade comprising Hishimonus Ishihara, Opsius Fieber, and an undescribed genus from Zambia. Additionally, we also analysed the relationships of Yinformibus gen. nov. with other genera based on morphology.

A remarkable new species of Euragallia from Peru (Insecta, Hemiptera, Cicadellidae, Agalliini), including the description of a peculiar structure of the male genitalia

A new species of Euragallia Oman, 1938 from Peru (Pasco Department) is described and illustrated. Euragallia batmanisp. n. can be distinguished from the other species of the genus by the very posteriorly pronounced male pygofer, with an apical hook-like projection, and by the well-developed dorsal area of the aedeagal base, resembling the open wings of a bat. With the addition of Euragallia batmani sp. n., the number of Euragallia species is increased to 21. Only one additional species of the genus is recorded from Peru (Euragallia prion Kramer, 1976). A comparison between the new species and Euragallia prion is provided. A conspicuous structure, which connects the subgenital plates to the styles, is described in detail and named.
