The following species are recognized: Mantelliceras mantelli (J. Sowerby, 1814), M. cantianum Spath, 1926a, M. picteti Hyatt, 1903, M. couloni (d'Orbigny, 1850), M. saxbii (Sharpe, 1857), M. dixoni Spath, 1926b, M. lateretuberculatum Collignon, 1964, M. nitidum (Crick, 1907), Utaturiceras vicinale (Stoliczka, 1864), Submantelliceras prenodosoides (Boule, Lemoine & Thévenin, 1907), Sharpeiceras laticlavium (Sharpe, 1855), S. falloti (Collignon, 1931), S. mocambiquense (Choffat, 1903), S. minor sp. nov., S. florencae Spath, 1925, Sharpeiceras sp. A, and Sharpeiceras sp. B. Submantelliceras Spath, 1923, variously regarded as a synonym of Mantelliceras and othergenera by previous authors, is shown to be a valid genus, and a paedomorphic dwarf. http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S2305-79632015000100002&lng=en&nrm=iso&tlng=en The cosmopolitan ammonite genus Douvilleiceras de Grossouvre, 1894, is the commonest ammonite in the Lowerand lower Middle Albian in northern KwaZulu-Natal. Two variable, dimorphic species, D, mammillatum (Schlotheim, 1813) and D. inaequinodum (Quenstedt, 1849) are recognized, of which the majority of previously named taxa referred to the genus are regarded as synonyms. http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S2305-79632015000100003&lng=en&nrm=iso&tlng=en Ophiuroid research in South Africa has not kept pace with global taxonomie research with the last major taxonomie review of the group being published in 1976. This paper documents all new records of Ophiuroidea from South Africa since (and including) 1977. These records originate from specimens housed in five zoological collections, from photographic records and from reports published in the non-taxonomic literature. A short review of the history of ophiuroid taxonomy in South Africa is also given and for each new record, key references, distribution, ecology, additional notes and, where possible, photographs, are presented. This has resulted in an additional 24 species being recorded within the mainland Exclusive Economic Zone of South Africa, elevating the total known number of ophiuroid species reported in the region to 137. http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S2305-79632015000100004&lng=en&nrm=iso&tlng=en We revise the Afrotropical genus Phorotrophus. Thirty-three species are recognized, including eight new synonyms and eight newly described species: P. cyranodebergeraci sp. nov., P. fernando sp. nov., P. frodoni sp. nov., P. hephaistosi sp. nov., P. problematicus sp. nov., P. vulcani sp. nov., P. youpi sp. nov., and P. zoutpansbergensis sp. nov. The following are considered junior synonyms: P. elevatus Benoit of P. alcides (Wilkinson); P. caffrariae Benoit of P. bivittatus (Morley); P. trimaculatus (Tosquinet) of P. capensis (Holmgren); P. katangensis Benoit and P. maynei Benoit of P. congoensis Benoit; P. basilewski Benoit, P. limpidus Benoit and P. nigromaculatus Benoit of P. mameti Benoit. New distribution records are included for P. alcides, P. bivittatus, P. congoensis, P. ealensis Benoit, P. kaluleus, P. mameti, P. perplexus Benoit and P. stictor Benoit. An illustrated dichotomous key to species is provided, and interactive dichotomous and matrix Lucid keys are also available at www.waspweb.org
