The following nomenclatorial changes are recorded in the African leafhopper genus Allophleps Bergroth, 1920 (Cicadellidae: Deltocephalinae, Athysaninae): Saudallygus Dlabola, 1979, a junior synonym of Allophleps, syn. nov.;, S. curvatus Dlabola, 1979 (the type species of Saudallygus), a junior synonym of A. elongata, syn. nov.; A. elongata (Melichar, 1912, Eutettix) comb. nov.; A. eques (Jacobi, 1910, Deltocephalus) comb. nov.; A. inspersa Bergroth, 1920, a junior synonym of A. eques, syn. nov. A new species, A. linnavuorii sp. nov., is established for specimens misidentified as A. inspersa by Viraktamath & Dash (2001); lectotypes are designated for Allophleps eques and A. inspersa and a key and figures are provided to distinguish males of the included taxa.

A new leafhopper genus, Bretega gen.n., (Hemiptera: Cicadellidae) is described from South Africa with 15 included species, all described as new: B. claviverpa sp.n., B. declispiverpa sp.n., B. delifurcaverpa sp.n., B. ensiverpa sp.n., B. furciverpa sp.n., B. juxtaspiverpa sp.n., B. Linnavuorii sp.n., B. orbiverpa sp.n., B. planuverpa sp.n., B. prospiverpa sp.n., B. quattuspiverpa sp.n., B. quinispiverpa sp.n., B. serraverpa sp.n., B. sexspiverpa sp.n. and B. truncuverpa sp.n. The new species are small leafhoppers with short forewings, non-functional hind wings and often with characteristic black markings on the head. They have been collected mainly on five species of shrubs in Asteraceae and possibly on two species in Malvaceae and Rutaceae. These plants were found in two arid habitats in the western parts of South Africa with a winter rainfall pattern and in a number of Karoo biomes in the central parts of South Africa with bimodal rainfall pattern. This new genus is placed in the Bonaspeiini of Deltocephalinae.

A new leafhopper species from China, Parabolopona basispina sp. nov., is described and illustrated and Favintiga camphorae (Matsumura, 1912) is reported for the first time from China. A key to the species of Parabolopona Matsumura is provided.

The classification and taxonomic composition of the grassland leafhopper tribe Hecalini in South America are reviewed and the following new endemic taxa are described and illustrated: Otamendiella linnavuorii, gen. & sp. nov.; Spangbergiella monzonensis, sp. nov.; S. oxapampaensis, sp. nov. A key to genera and species, checklist and synonymy of South American Hecalini are also provided. The known hecaline fauna of South America now comprises seven described species belonging to three genera.

A checklist to Chinese Idiocerinae and a key to included genera is provided and Anidiocerus fasciatus Xue & Zhang, sp. nov. from China is described and illustrated. Megipocerus Zakhvatkin and its type species, Megipocerus mordvilkoi Zakhvatkin, are newly recorded from China, the genus is redescribed and the species figured.

A new leafhopper, Odomas linnavuorii sp. nov. (Cicadellidae: Megophthalminae: Megophthalmini), is described based on a brachypterous female collected in the subalpine grassland in the highest part of the Mt Nimba massif, Guinea, West Africa. The new species has a highly derived head and wing structure and is densely covered with chalazal setae. As these features are unique both within the genus and tribe the morphology and the systematic placement of O. linnavuorii are discussed in the context of other ground-dwelling taxa of Membracoidea. In addition, the monotypic Afrotropical genus Coronophtus Van Stalle, 1983 is removed from Cicadellidae: Megophthalminae and synonymised with Listrophora Boulard, 1971 (Cicadellidae: Deltocephalinae: Chiasmini), resulting in one new combination, Listrophora cervus (Van Stalle, 1983), comb. nov.

Six new species of Neopsis from montane Atlantic forest and Cerrado of Brazil (Minas Gerais) and montane Amazon forest of Peru are described and illustrated. Neopsis amazonica Hamilton is newly recorded from Amazonas State (Brazil) and its male is described and illustrated for the first time. The female terminalia of Neopsis robusta Linnavuori and Lonnia pallida (Linnavuori & DeLong) are also illustrated for the first time. A key to all eleven species of the genus is provided. Tribe Neopsini is newly placed in subfamily Tartessinae, a subfamily previously recorded only from the Australian and Indomalayan regions, based on morphological characters and phylogenetic evidence.

Aloka depressa gen. et sp. nov. (Signoretiinae) from India (Karnataka: 36 Km West Jog Falls) representing the first record of the tribe Phlogisini from the Indian subcontinent is described and illustrated. It resembles Phlogis Linnavuori from Africa but differs in having a less arcuate pronotum that lacks lateral foveae, much broader face and depressed male genital capsule. The male of Phlogis mirabilis Linnavuori collected from Africa is also described and illustrated for the first time.

The dimorphic African leafhopper Conlopa bredoni Evans (Cicadellidae: Ulopinae) is refigured, its genus redescribed and its tribal placement discussed and a key to the tribes of Ulopinae provided. Conlopa bredoni and another ulopine, Coloborrhis corticina Germar, were recently collected from dung baited pitfall traps in Zambia (new records), together with some other Auchenorrhyncha.

The Oriental genus Protolepta Melichar is revised to include two species: P. turbata (the type species) and P. linnavuorii sp. nov., both from Sulawesi, Indonesia. Redescription is provided for P. turbata together with habitus photographs and detailed illustrations of the male genitalia for the first time. A key to the species of the genus and a distribution map are given.

The African and Middle East species of the genus Lophops Spinola, 1839 are revised and 7 new species are described: L. bwamba, L. incognita, L. kwazulu, L. malagarassi, L. sigwalti, L. stilleri and L. watshami. A key to the African species is provided.

A new species of the genus Exphora Signoret, 1860 (Tropiduchidae, Elicinae, Elicini) is described from Madagascar: Exphora linnavuorii sp. n. An identification key to all Exphora species is provided.
