Pristiophorus cirratus ( non Latham): Thompson, 1914: 153 . A single record of this species is based on a specimen from False Bay (WC) that was a misidentification by G.A. Boulenger, but later used by Regan as one of the two syntypes for P. warreni (see Barnard, 1925: 53 ; Smith, 1949a: 61 ; Smith, 1965: 61 ). South Africa voucher material : Syntypes : BMNH 1899.2 .10.4, BMNH 1905.6 .8.9.

South Africa distribution : Table Bay (WC) to the KZN border with Mozambique. Remarks : The genus Pliotrema has been considered to be monotypic, but a recent revision has revealed two new species in the genus ( Weigmann et al. , 2020 ); both new species do not occur off South Africa . The global distribution of P. warreni is now considered to range from central Namibia to southern Mozambique , with most of the population occurring on the Agulhas Bank (EC), South Africa . Conservation status : LC (2020).
