A new species of deep water skate, Raja (Dipturus) crosnieri, is described from 23 specimens, juveniles and adults of both sexes, trawled on the continental slopes of the north-western coast (off Nosy Be) and south-western coast (off Tulear) of Madagascar, between 300 and 850 m depth. The taxonomic status of subgenera Dipturus Rafinesque, 1810, and Okamejei Ishiyama, 1958, is discussed and the new species is compared to its congeners of subgenus Dipturus.
