Sometimes placed in genus Phalacrocorax, Stictocarbo or occasionally in Leucocarbo, but classification here follows results of a comprehensive molecular phylogeny for the entire family#R. Race riggenbachi may be inseparable from desmarestii; further investigation required. Three subspecies tentatively recognized.

  • G. a. desmarestii (Payraudeau, 1826) – C Mediterranean E to Black Sea.
