Abstract
This paper examines the alpha level taxonomy of the genus Haploblepharus Garman, 1913 (Chondrichthyes; Scyliorhinidae). Three species are endemic to South Africa, with one species occurring in Namibia and South Africa. Haploblepharus pictus exhibits considerable colour variation which has led to some confusion between that species and H. edwardsii, resulting in a significant range extension for H. pictus. A neotype is designated for H. edwardsii, and problematic Haploblepharus juveniles are tentatively assigned to H. kistnasamyi. A novel species identification key is presented for Haploblepharus, and a comprehensive review of the taxonomy (including type material and synonyms) and distribution of all taxa is presented. The genus Haploblepharus contains four contemporary taxa: H. edwardsii (Schinz, 1822), H. pictus (Müller & Henle, 1838), H. fuscus Smith, 1950, and H. kistnasamyi Human & Compagno, 2006.References
