A key is provided to 14 species of Scirtothrips recorded from Africa south of the Sahara, including Cape Verde Islands. S. dodonaeae sp. n. is described from Dodonaea in South Africa, and the possibility is discussed that South African populations here referred to as S. aff. dorsalis represent a new species. Type specimens of the six Scirtothrips species described by J.C.Faure have been re-examined, and brief diagnoses are provided for all 14 species. Copyright © 2011 - Magnolia Press. Source

A new endemic deltocephaline leafhopper, Tetramelasma gen.n. is described from the Grassland Biome of South Africa, comprising four new species: T. litopyx sp. n., T. nodosatha sp. n., T. scolosatha sp. n. and T. tanyphysis sp. n. Two paired dark markings on the vertex of the head are striking features of this genus and it is found in association with a number of grass species usually at high altitudes in the Grassland Biome. Species of this genus are characterized in the male by a short, truncated plate with a dorsal sclerotized process, the aedeagus with a long, slender shaft that is fused with the connective. Tribal placement in Deltocephalini is based on the fusion between the aedeagus and connective. The style has the posterior apophysis short and hollow or elongate and somewhat serrated. Females are characterized by the sternite 7 that is deeply invaginated along the posterior margin or only with a shallow notch, semicircular and sclerotized laterally.

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 the following from South Africa, Xerophytavorus rastrullus gen.n &sp.n. (Opsiini), Xerophytacolus claviverpus gen.n &sp.n. and Xerophytacolus tubuverpus gen.n &sp.n. (Opsiini). Copyright © 2012 • Magnolia Press. Source

Pravistylus is assigned to the tribe Paralimnini. A key is provided for the identification of species. © 2010 Magnolia Press. Source

The South African grass-feeding leafhopper Vilargus Theron is revised. Vilargus pumilicans (Naudé) is redescribed and the specific status of V. campanus (Naudé) is discussed. Seven new species of Vilargus are described: V. bicornicans sp. n., V. budenticans sp. n., V. dentulicans sp. n., V. lobulicans sp. n., V. simulans sp. n., V. triquetricans sp. n. and V. trunculicans sp. n. A key is provided to males and known females of Vilargus. The species of this genus are small, light brown leafhoppers, commonly associated with grass in the Grassland Biome of South Africa, and rarely from the Savanna and Fynbos Biomes.Copyright © 2010 Magnolia Press.
