Centroselachus crepidater (Barbosa du Bocage & de Brito Capello, 1864) Longnose Velvet Dogfish Centrophorus crepidater Barbosa du Bocage & de Brito Capello, 1864: 262, fig. 3. Holotype (unique): MB t.112(49) [destroyed in fire in 1978]. Denticles from holotype in MCZ 89511. Type locality: [Nossos mares] Portugal, northeastern Atlantic. Local synonymy : Centroscymnus crepidater : Compagno et al ., 1989: 32, pl.; Compagno et al ., 1991: 58; Ebert et al ., 1992: 604; Compagno, 1999: 115.

South Africa voucher material : SAIAB 25724, SAIAB 26278, SAIAB 26279, SAIAB 26280, SAIAB 26281, SAIAB 26337, SAIAB 27599, SAIAB 27600, SAIAB 27602. South Africa distribution : The Orange River (NC) to Cape Agulhas (WC), but not yet confirmed from the EC or KZN. Remarks : First reported in South African waters by Compagno et al . (1989) and Compagno et al . (1991); previous southern African records were from off Namibia (Bass et al ., 1976; Bass et al ., 1986). Although the species has not been reported from the EC or KZN, it is quite common east of South Africa along the Madagascar Ridge. A somewhat common species along the upper continental slope, C. crepidater appears to be a faunal associate of C. coelolepis since both species are frequently collected together (Compagno et al ., 1991). Conservation status : NT (2020). Genus Scymnodalatias Garrick, 1956 Spineless Velvet Dogfishes Scymnodalatias Garrick, 1956: 564.
