Four new species in two new genera of leafhoppers (Hemiptera, Auchenorrhyncha, Cicadellidae, Deltocephalinae) are described. All are associated with Xerophyta species (Velloziaceae, Pandanales), and are usually tended by ants. Observations and discussions of the ant associations are provided. The new leafhopper genera and species are: Xerophytavorus furcillatus gen.n & sp.n., from Malawi, and t...

Evacanthinae is a small subfamily in the Cicadellidae (Young, 1968; Zhang, 1990). It was redefined by Dietrich (2004), who included the tribes Evacanthini, Nirvanini, Balbillini and Pagaroniini in this subfamily. Recently, a new species was found in loaned material from Thailand, having several peculiar features worthy of establishing a new genus, described below. In addition, based on study of...

Sweta bambusanasp. n. (Hemiptera: Cicadellidae: Typhlocybinae: Dikraneurini), a new bamboo-feeding species, is described and illustrated from Guizhou and Guangdong of China. This represents the first record of the genus Sweta Viraktamath& Dietrich from China and the second known species of the genus. The new taxon extends the range of the genus Sweta, previously known only from northeast India ...

We review the world literature on leafhoppers (Cicadellidae) that have probed human skin, update the names presented in those published reports, and sort out which are original accounts and which are citations of previous reports (Table 1). We add 19 new records, representing five subfamilies, and at least 13 genera, all from Panama (Table 2). We speculate as to why these normally phytophagous ...

A new genus of Chinese Empoascini (Hemiptera: Cicadellidae: Typhlocybinae), Radicafurcus Qin & Zhang, gen. n. with one new species, R. breviprocessus Qin & Zhang, sp. n. from Sichuan Province (S.W. China) is described and illustrated. Baguoidea Mahmood 1967 is redescribed and a new species, B. yunnanensis Qin & Zhang, sp. n. is described from Yunnan Province (S.W. China). Two genera (Faiga Dwor...

Aboveground Hemiptera and Orthoptera communities were compared among three native and three restored mesic tallgrass prairies along the Platte River in central Nebraska to assess both the relative success of restored sites and the relationship between insect and plant communities. Hemiptera and Orthoptera were sampled using sweep nets in early June, mid-July, and mid-August 2000. Plant species ...

Particular alkaloids produced by Neotyphodium endophytes show toxicity to invertebrates. Italian ryegrass (Lolium multiflorum Lamarck) cultivars and strains that are symbiotic with Neotyphodium endophytes have been recently established in Japan. N. uncinatum-infected Italian ryegrass lines accumulate N-formylloline, a type of loline alkaloid (1-aminopyrrolizidine) showing neurotoxicity to herbi...

in the course of our faunistic survey on leafhoppers (hem.: cicadellidae) in northwestern iran, 46 species were collected and identified of which the species macrosteles chobauti ribaut, 1952 is newly recorded from iran. drs. hani abdul-nour (lebanese university, lebanon) and paul freytag (university of kentucky, usa) confirmed the identification of the species.
