The ostracod fauna of southern Africa remains ill-known, in spite of the fact that the temporary pools of this zoogeographical region hold degrees of endemicity comparable only to those of the ancient lakes of East Africa. The present contribution describes a new species of the cypridid genus Amphibolocypris, A. arida sp.nov., and announces the existence of at least two further new species from the same area. The genus, up to now presumed monospecific, might constitute an extensive radiation across southern Africa. Unusually large species-specific differences in hemipenis outline morphology appear to indicate that speciation occurred through sexual, rather than through natural selection. The occurrence of the claw-like subapical seta on the walking limb in at least four genera could be a case of convergent evolution, at least in one, maybe even in two cases between species of different genera and even subfamilies.

A new species of Cladocera, Alona begoniae sp. nov. (Anomopoda: Chydoridae) was found in ancient Lake Ohrid. Its habitus and outer morphology is similar to one of the most common Palearctic species, Coronatella rectangula (Sars, 1862), and this can be the main reason why it has remained undiscovered. A. begoniae sp. nov. belongs to the elegans-group of Alona s. lato, a relict genus-level group not formally recognised yet as a separate taxonomical unit. Its habitat seem to be sandy and stony substrates (at 2–12 m depth) bare of vegetation. The position of this new species within the Alona-like anomopods is evaluated and similarities with other cladocerans in ancient lakes are discussed.

A new species Exormotheca bulbigena is described from southern Africa and its relation to E. holstii Steph. is discussed. Morphologically these species arc very similar and can be distinguished only when fertile. The chromosome numbers, however, n = 32 for E. bulbigena and n = 18 for E. holstii, distinguish sterile living plants.

The genus Acanthistius Gill, 1862 comprises ten putative valid species occurring in shallow warm-temperate waters of the Southern Hemisphere: South America (coasts of Ecuador, Peru, Chile, Brazil, and Argentina) southern Africa (Namibia and South Africa), southern Australia, New Zealand, Lord Howe, Norfolk, Kermadec and Easter, and Sala y Gómez islands. Two species: Acanthistius sebastoides (Castelnau, 1861) and Acanthistius sp are known from shallow waters of the east coast of South Africa (Heemstra and Randall, 1986). The latter taxon, previously known from a brief description of a single specimen, is here described from 23 specimens and named Acanthistius joanae. Acanthistius sebastoides is redescribed from 13 specimens and compared with A. joanae and species of Acanthistius known from South America and Australia. A neotype is designated for Serranus sebastoides Castelnau, 1861, as the two syntypes are apparently lost.

AbstractA new species of Trox, T. mozalae, from coastal sand forest in Mozambique, is described. T. natalensis quadricostatus Scholtz is elevated to species-level and T. natalensis schaborti Scholtz and T. elizabethae van der Merwe & Scholtz are synonymised with it. A key to the subgenus Phoberus MacLeay, to which most of the flightless species in Africa belong, is provided. All species incorporated into the key are illustrated by photographs of habitus and aedeagi. A map is provided of the distribution of each of them.

In the course of his excavations in the Upper Eocene beds of the Fayûm during the early part of 1902, Mr. H. J. L. Beadnell unearthed a remarkably fine shell of a very large species of Testudo. A brief description of this specimen was afterwards published in Cairo by the present writer, and it was made the type of a new species, Testudo Ammon. At the same time Mr. Beadnell gave a short account of the beds in which it was found, and of the methods employed by him for its preservation and transport to the Museum in Cairo.
