During the trawling survey for shrimp fisheries undertaken by the ORSTOM Center in Nosy-Be (small island of Madagascar) from 1971 to 1975, twelve specimens of deep-water skates were collected off the West coast of Madagascar (part of A. Crosnier’s collection). Two are referred to Anacanthobatis ori (Wallace, 1967), previously known only from the type-specimens (holo- and paratype) reported from off Bazaruto Island (Mozambique). A. ori is compared with its congeners so far described from the Indo-Pacific region and from the Western Central Atlantic.
