South Africa distribution : The Orange River (WC) to KZN border with Mozambique. Remarks : The South African “short-nose” Squalus species-complex ( S. acutipinna , S. cf. blainville , S. mahia , S. margaretsmithae , and Squalus probatovi ) is in need of extensive taxonomic revision to clarify and identify regional species. The occurrence of five co-occurring “short-nose” species seems unlikely given molecular ( Veríssimo et al ., 2017 ) and ecological data ( Ebert et al ., 1992 ; unpubl. data), which does not support this number of species. Therefore, until further detailed data are available S. margaretsmithae and S. probatovi are considered junior synonyms of S. acutipinna . Conservation status : NT (2020).
