Abstract:
The East African freshwater crab Potamonautes obesus (A Milne-Edwards, 1868) (family Potamonautidae) is redescribed from a large series of specimens from Tanzania and Somalia, and Potamon (Potamonautes) bottegoi de Man, 1898 is judged to be a junior objective synonym of P. obesus. The related taxon, Potamonautes calcaratus (Gordon, 1929) from Mozambique and South Africa, is recognised here as a valid species and is redescribed from type material. The distributions of P. obesus and P. calcaratus are described and discussed.

Abstract:
AbstractPotamonautid river crabs were collected from four sites along the Olifants River in the Western Cape, South Africa in order to determine morphological and genetic differentiation among these populations. Two distinct forms were identified, and fixed allele differences at some allozyme loci between sympatric populations of the two forms confirmed that they were reproductively isolated. It was concluded that these forms represent two species, one of which was previously unknown, and is described in this paper as Potamonautes parvispina sp. nov.

Abstract:
ABSTRACTRecent taxonomic studies of forest habitats in South Africa have revealed the presence of three new species of freshwater crabs, suggesting that decapod diversity within the indigenous forest biome remain poorly documented. Surveys of the freshwater crabs of north eastern KwaZulu-Natal province produced a number of specimens from Ntendeka Wilderness Area (Ngome forest) and Nkandla and Ngoye forests that proved to belong to two new species following morphological and molecular analysis (mtDNA sequencing of three loci, 12S rRNA, 16S rRNA and COI).

Thesis (PhD)--University of Stellenbosch, 2002.<br>ENGLISH ABSTRACT: In the present study, the systematic status, aspects of the evolutionary biology and phylogenetic relationships among species of the African freshwater crab genus Potamonautes in South Africa are examined. Systematic research between allopatric populations of P. brincki, using allozyme and morphometric data has revealed the existence of a new undescribed freshwater crab species occurring in mountain streams of the Cape Peninsula. This species is described in the present study. In addition, the diagnostic value of carapa

The urban rivers of the Western Cape are no different. The Lourens River flows through the agricultural and urban areas of Somerset West in the Western Cape and as a result is subjected to a variety of pollution sources. In the upper reaches this river flows through two large farms where metal containing pesticides are used. Further downstream it passes through an urban area where a variety of pollution sources could contribute to the con
