Outside South Africa , this regional endemic is known only from southern Mozambique and Madagascar . Remarks : Human (2006b) highlighted three issues that contributed to the taxonomic confusion of this species. This includes the loss of the holotype and whether it was ever formally accessioned, the type locality, and the species-complex in the KZN and southern Mozambique region. The specimen and illustration depicted by Gilchrist (1914) would qualify as the holotype , and it is likely to have gone to the SAM, but may never have been catalogued. During that period there is no reference to a scyliorhinid shark collected by Gilchrist in the SAM catalogue ( Human, 2006a ). Although Gilchrist (1914) gives the type locality as Cape Point with no further details, Human (2006a) suggested that he was referring to Cape St. Lucia (KZN) rather that Cape Point (WC). This would make sense since despite thousands of survey trawls in the WC over the past five decades this species has not been observed. However, its occurrence in KZN waters is not unexpected. Furthermore, the survey vessel S.S. Pickle traveled continuously between the WC and KZN during the early 1900s. The KZN and southern Mozambique region has several species of Holohalaelurus co-occurring and until recently a lack of accurate descriptions precluded species-specific identification ( Human, 2006 ).
