“…The presence of G. macrolepidotus in the Upper Zambezi System was confirmed by Jubb (1958). We disagree with Gilchrist and Thompson's view (1917, p. 562) that their description of a South African specimen of Gnathonemus macrolepidotus (in Gilchrist and Thompson 1913) closely matches that of G. macrolepidotus from the Upper Zambezi.…”

Allopatric differentiation in the AbstractWe critically compared local populations of the bulldog fish, Marcusenius macrolepidotus (Peters 1852), from different watersheds, from the furthest south (28u South, South Africa) to the Equator in Kenya. We ascertained allopatric differentiation from topotypical M. macrolepidotus from the Lower Zambezi River (Mozambique) in morphology, electric organ discharges, and molecular genetics for: (1) samples from the Okavango and Upper Zambezi Systems (Botswana and Namibia), (2) samples from South Africa's rivers draining into the Indian Ocean, and (3) samples from the East African Tana River (Kenya). Significant genetic distances in the mitochondrial cytochrome b gene and differing ISSR-PCR profiles corroborate differentiation between the four taxa. We resurrect M. pongolensis (Fowler, 1934) for South Africa (sample 2), and M. angolensis (Boulenger, 1905) for the Quanza River/Angola. We recognize M. altisambesi sp. n. for the Upper Zambezi/Okavango specimens (sample 1), and M. devosi sp. n. for those from Kenya (sample 3).

“…In the description Smith referred to "four grown specimens", of which only one is known to survive, preserved in the Natural History Museum, London (NHMUK). The species was initially recognized as the Berg-Breede River whitefish or witvis (Afrikaans for whitefish) (Boulenger 1911;Gilchrist & Thompson 1913;Barnard 1937). However, on information that he received from J.R. Norman at the NHMUK about the form of the scales of the type specimen, Barnard (1937) attributed the name to the Clanwilliam yellowfish, a well-known species from the Olifants River system (Skelton 2001).…”

“…Accordingly, they restored the name of the witvis to Barbus capensis (Smith, 1841) and that of the Clanwilliam yellowfish to Labeobarbus seeberi (Gilchrist & Thompson, 1913). As both the witvis and the Clanwilliam yellowfish are large and well-known species, these scientific name changes are undoubtedly disruptive to the community and need a clear explanation (Skelton 2016).…”

Abstract. The identity of Barbus capensis, as described by Andrew Smith (1841), is reviewed following a careful examination of the lectotype in the Natural History Museum, London. Evidence shows clearly that it represents a specimen of the Berg-Breede River whitefish or 'witvis' and not the species known as the Clanwilliam yellowfish, to which it was attributed until recently. The original illustration of the species is shown to be a composite of these two different species. A replacement name for the Clanwilliam yellowfish is drawn from the earliest described synonym, Labeobarbus seeberi (Gilchrist & Thompson, 1913). Following widespread recognition that the genus Barbus Daudin, 1805 does not occur in subSaharan Africa, the generic status of the Berg-Breede River whitefish (witvis) and other tetraploid cyprinines of southern Africa is reviewed, taking genetic and morphological characters into account. Five distinct lineages, each representing a genus, are recognized, including the genera Pseudobarbus Smith, 1841 and Cheilobarbus Smith, 1841, and three new genera described herein: Amatolacypris gen. nov., Sedercypris gen. nov. and Namaquacypris gen. nov.

1. Mediterranean climate regions are globally recognized as hotspots of endemism in fishes; however, these unique assemblages are increasingly threatened by human mediated impacts including water abstraction, damming and non-native species introductions.2. The Cape Fold aquatic ecoregion (CFR) of South Africa supports an assemblage of range-restricted endemic freshwater fishes, the majority of which are conservation priorities because they are under severe threat of extinction. Effective conservation and management are constrained by the lack of readily available information on this imperilled group of fishes because research efforts over the last century have been temporally disjointed and relatively uncoordinated.3. This review provides an exhaustive appraisal of published literature on the taxonomy, biogeography, life history, ecology and physiology of freshwater fishes in the CFR, and the human impacts that affect them. Its aim is to direct future research needs for effective management and conservation of this imperilled group. 4. Only 103 peer-reviewed articles on CFR fishes were recorded and the majority of available research is on taxonomy and biogeography (40.8%), followed by ecological investigations (22.3%), conservation (19.4%) and human impacts (17.5%). 5.Despite a plethora of studies on taxonomy and biogeography, recent genetic evidence suggests that fish diversity in the CFR has been severely underestimated and requires urgent attention. Human impacts severely threaten the existence of many native CFR fishes and require further study. Information on the biology and ecology of CFR fishes is limited to studies on selected species; of particular note is the lack of physiological information which is particularly pertinent given projected climate change scenarios.
