The genus Pagellus is placed in the family Sparidae within the order Spariformes by the 5th edition of Fishes of the World.[1] Some authorities classify this genus in the subfamily Pagellinae,[2] but the 5th edition of Fishes of the World does not recognise subfamilies within the Sparidae.[1]

The fusiform, elongate body, the standard length is 2.8 to 3 times the depth, is moderately compressed. The dorsal profile of the head is convex between the upper lip and the origin of the dorsal fin.
