Classification / Names Nombres comunes | Sinónimos | Catalog of Fishes(Género, Especie) | ITIS | CoL | WoRMS | Cloffa

Elasmobranquios (tiburones y rayas) (sharks and rays) > Squaliformes (Sleeper and dogfish sharks) > Centrophoridae (Gulper sharks)
Etymology: Centrophorus: centr[um] (L.), prickle or sharp point; phorus, from phoreus (Gr.), bearer or carrier, referring to grooved spines on dorsal fins. (See ETYFish); lusitanicus: -icus, belonging to: Lusitania, ancient name of Portugal, type locality (although identity of holotype is in dispute, treated as a junior synonym of C. granulosus by some workers). (See ETYFish).

Issue
Portugal and so must be considered a junior synonym of the latter species. The purported syntype BMNH 1867.7.23.2 is not a type specimen and refers to a separate long-finned species (see Ref. 116740 for available evidence).
