South Africa voucher material : Uncatalogued specimens at SAM . South Africa distribution : Mossel Bay (WC) but likely more wide-ranging. Remarks : Most previous records of this species from South Africa were misidentifications with either C. coelolepis or C. crepidater , but a few specimens of this species were caught in very deep water off Mossel Bay. This record, along with several specimens caught east of South Africa on the Walters Shoal and Madagascar Ridge, confirm the widespread distribution of this species. Conservation status : VU (2018).
