Most haustoria in Hyobanche (Scrophulariaceae) are formed directly from the scale leaves of the extensive rhizome system and may be found on adaxial surfaces, margins, or tips of such leafy organs. The only exceptions are occasional haustoria, emerging from rhizome areas between adjacent scale leaves, and the primary haustorium. Host roots appear to be attracted to the rhizome, growing along its surface and apparently eliciting haustorial formation in adjoining parasitic tissues. The established parasite is completely rootless.

A revision of the south African genus Neopimus Özdikmen, Demir & Türkeş, 2008 is presented. Based on revision of the type and additional material, three species are recognised. The genus Neopimus is redescribed and all species are described or redescribed and illustrated, two of them for the first time: Neopimus capensis Janák, sp. nov., from Eastern Cape Province, South Africa and N. zulu Janák, sp. nov., from KwaZulu-Natal Province, South Africa. The distribution of the genus is mapped and a key of species is presented.

Systematists have frequently interpreted lateral compression of the idiosoma in post-larval instars of water mites as a synapomorphy indicating common ancestry. This paper re-examines the evidence to support this assumption and concludes that lateral flattening has occurred independently several times during water mite evolution, and especially often in various basal clades of the superfamily Hygrobatoidea. Reassessment of the phylogenetic relationships of the genera attributed to these clades results in improved understanding of the early evolution and biogeography of hygrobatoid water mites and necessitates redefinition of several clades and significant revision of the family classification. The South African genus Karlvietsia K.O. Viets, 1962 is transferred from the subfamily Frontipodopsinae of the family Aturidae to the Hygrobatidae. The Australian genera Tasmanaxona Cook, 1986, Wheenyella Cook, 1986 and Wheenyoides Harvey, 1990 are also removed from Frontipodopsinae and placed with the genus Wettina Piersig, 1892, here removed from the family Pionidae, in the family Wettinidae Cook, stat. nov. Based on apparent relationship with members of Wettinidae, the South African genus Stormaxonella K.O. Viets, 1962 is transferred from the Aturidae and provisionally placed in the Wettinidae. The clade including the predominately Holarctic genus Lethaxona K.H. Viets, 1932 and the Western Hemisphere genus LethaxonellaCook, 1963 is recognised as the probable sister group of Wettinidae, and these genera are consequently removed from the Aturidae and placed in Lethaxonidae, fam. nov. The genus Frontipodopsis Walter is reassigned from Aturidae to the now monobasic family Frontipodopsidae K.H. Viets, stat. nov. Finally, five new species are described, including Frontipodopsis (Frontipodopsella) sudafricanus, sp. nov., Wettina occidentalis, sp. nov., Karlvietsia simplex, sp. nov., Hygrobates (Hygrobates) gereckei, sp. nov. and Hygrobates (Hygrobatides)frontipodoides, sp. nov., and both Karlvietsia brevipalpis K.O. Viets and K. angustipalpis K.O. Viets are redescribed.

The South African genus Griffiniana Karny of squamipterous to macropterous katydids (Tettigoniidae: Mecopodinae:Aprosphylini) is revised and a key to species is provided; G. duplessisae sp. n. from the Western Cape Province is de-scribed; acoustic behavior of G. capensis Karny, G. duplessisae, and G. longipes (Naskrecki) is described. The genusEwanella Naskrecki is considered a junior synonym of Griffiniana, and E. breviuscula Gorochov is synonymized with G. longipes.

The South African genus Austrodontura Fontana & Buzzetti of brachypterous katydids is revised. A. capensis (Walker, 1869) is redescribed and A. castletoni sp. n. from the Eastern Cape Province is described, A. raggei Fontanta & Buzzetti is considered a junior synonym of A. capensis. Acoustic behavior of A. castletoni is described.

SUMMARYStudy of casts of Stegomosuchus, a small reptile from the Upper Trias of the Connecticut Valley, hitherto regarded as a pseudosuchian thecodont, suggests that the skull of Protosuchus includes two pairs of supraorbital bones, and as a consequence the narrow interorbital region indicates a closer relationship to the South African genus Notochampsa than has previously been thought. These three genera of late Triassic crocodilians are placed in the family Stegomosuchidae von Huene, 1922. Proterochampsa, from the Ischigualasto Formation of Argentina, described by Reig (1959) and Sill (1967) as an ancestral crocodile, is considered to be an extremely primitive phytosaur.
