Crenidens is a small genus of three species of seabream from the family Sparidae from the western Indian Ocean. It was previously regarded as monotypic, with the sole species being the Karenteen sea bream Crenidens crenidens but two other species are now accepted as valid species, separate from the type species, C. crenidens.
Crenidens was first proposed as a monospecific genus in 1830 by the French zoologist Achille Valenciennes with Crenidens forsskalii as its only species and the type species by monotypy.[1] C. forsskalii is now considered to be a synonym of Sparus crenidens, originally described by Peter Forsskål from the Red Sea of Saudi Arabia and Egypt in 1775.[2] This genus is placed in the family Sparidae within the order Spariformes by the 5th edition of Fishes of the World.[3] Some authorities classify this genus in the subfamily Boopsinae,[4] but the 5th edition of Fishes of the World does not recognise subfamilies within the Sparidae.[3]
Etymology
Crenidens combines creni, meaning “crenulate”, with dens, which means “teeth”, an allusion to the crenulate incisor-like teeth of these fishes. This is not tautonymous with Sparus crenidens as Valenciennes had unnecessarily renamed that species C. forskalii.[5]
Species
Crenidens contains three recognised species.[6] It was considered to be monotypic but a second and third species are now regarded as valid.[7][8]
