The genus Bagnallella Salmon is restored and given a diagnosis. It takes an intermediate position between Proisotoma Börner and Cryptopygus Willem complexes and is characterized by the separation of the two last abdominal segments (like in Proisotoma) and 3 and 5 s-chaetae on the fourth and fifth abdominal segments (like in Cryptopygus and its allies). A list of and key to species belonging to Bagnallella is given. Bagnallella bisetacomb. nov., B. dubiacomb. nov., B. sedecimoculatacomb. nov., and B. tenellacomb. nov. are commented and redescribed. Morphology of Bagnallella davidi (Barra), comb. nov. is described from the specimens from South Africa. So far B. davidi appears to be a complex of forms differing in size of the furca and macrochaetae. Two types of strongly modified males were found and described. Antennae, ventral side of abdomen, posterior edge of abdominal tergites, and mandibles are affected with epitoky. The nature of the discovered strong polymorphism is unclear.

The sea-urchins (class Echinoidea) of South Africa have received little taxonomic attention since the last comprehensive regional monographic guide, which was published in 1976 and is thus now severely outdated. That account was also poorly illustrated, making it difficult to use. Recent work by the authors has also added some 19 additional species to the known fauna, which now stands at 70 species. The aims of this study are thus to revise and update the South African echinoid fauna list, and to present a new, easy to use and fully-illustrated guide to all known regional species. The analysis is based mainly on examination of samples from the Iziko South African Museum collections, although additional records from other museum collections, the published literature, photographic images submitted to the EchinoMap Virtual Museum Database and any other reliable records are also included. A short account of each species is given, including relevant synonymy and literature, and brief notes on identification, size, and global distribution. Photographs that best represent the diagnostic features of each species and a map showing its known records within the region accompany each species account. A binary key to species is also provided.

One New Species

Species of the genera of the Cryptopygus complex in South Africa are morphologically revised. Five new species of the genus Cryptopygus Willem, 1902 s. s. and one new species of the genus Isotominella Delamare Deboutteville, 1948 are described. Cryptopygus abulbussp. nov. and C. bulbussp. nov. have only one chaeta on the anterior side of dens and no chaetae on the anterior side of manubrium, the latter species being characterized by the presence of a bulb at apex of antennae; C. inflatussp. nov. shows a rare combination of eight ocelli on each side of the head with a tridentate mucro; C. longisensillussp. nov. has five long s-chaetae on the fifth abdominal segment; C. postantennalissp. nov. is unique by having a very long and slender postantennal organ with strong inner denticles; Isotominella laterochaetasp. nov. is the second member of the genus and differs from the type species by many more anterior chaetae on the manubrium and the presence of chaetae on ventral side of metathorax. The genera are discussed and a key to all species of the Cryptopygus complex recorded in South Africa is given. The focus is on the Western Cape Province where the complex is the most diverse and sampling more complete than in other provinces of South Africa.

The genus <em>Canthyporus</em> Zimmermann, 1919, is revised. A total of 35 species are recognized, all of them distributed within the Ethiopian Region, and with a centre of diversity in the South African Western Cape province. Descriptions of all species are given together with illustrations of habitus and male and female genitalia. A key to species (males), distribution maps, and ecological information are provided. Four new species are described from South Africa: <em>Canthyporus aenigmaticus</em> n.sp., <em>C</em>. <em>nimius</em> n.sp., <em>C. turneri</em> n.sp., and <em>C. wewalkai</em> n.sp. The species <em>C. congener</em> Omer-Cooper, 1956, is regarded as valid and not as a junior synonym of<em> C. canthydroides</em> (Régimbart, 1895). Lectotypes are designated for the following ten names:<em> C. alvei</em> Omer-Cooper, 1965, <em>C. consuetus </em>Omer-Cooper, 1965, <em>C. latus</em> Omer-Cooper, 1965, <em>C. lowryi </em>Omer-Cooper, 1965, <em>C. nebulosus</em> Omer-Cooper, 1965, <em>C. similator</em> Zimmermann, 1923, <em>C. simulator</em> Guignot, 1959, <em>C. testaceus</em> Zimmermann, 1923, <em>Hydroporus collaris</em> Boheman, 1848, and <em>Hydroporus hottentottus</em> Gemminger &amp; Harold, 1868. A parsimony analysis based on 32 morphological characters found 28 shortest trees. Monophyly of the genus <em>Canthyporus</em> is supported mainly by the presence of an anterior ligula on the ventral side of the elytron. Four species groups are recognized within the genus: (1) <em>canthydroides</em> group, including ten species in Namibia and South Africa; (2) <em>exilis</em> group, including four species in Lesotho and South Africa; (3) <em>hottentottus</em> group, including 18 species from the Democratic Republic of the Congo, Ethiopia, Kenya, Lesotho, Madagascar, South Africa, Swaziland, Tanzania, and Zimbabwe; and (4) <em>lateralis</em> group, including three species from South Africa.

The Old World members of the genus Parabaeus Kieffer are revised and a key to species provided. Previously only known in the Old World from the holotype P. ruficornis Kieffer (Seychelle Is), the fauna of this region is expanded to six species, viz. P. abyssus, sp. nov. (Western Australia), P. africanus, sp. nov. (Malawi), P. quasimodus, sp, nov. (Kenya), P. peckorum, sp. nov., and P. armadillus, sp. nov. (South Africa). Apterous members of the genus possess the most highly fused mesosoma of the Platygastridae (sensu Masner and Huggert 1989). The function of this morphology is discussed and compared with other apterous genera in the family.
