Abstract

Morphological analysis of South- and Northwestern Atlantic specimens of Squatina revealed an undescribed species of angel shark occurring on the continental slope of Brazil between latitudes 11° and 22°S. The new species of Squatina is distinguished from western Atlantic congeners by a unique combination of dorsal color pattern, vertebral counts, morphology of lateral dermal folds, dermal denticles, female reproductive tract, clasper, and pectoral fin characters. A preliminary assessment of the taxonomy of angel shark species from the Central and Northwestern Atlantic is also provided.
