ABSTRACT:
A new Southwestern Atlantic species of Parmaturus, P. angelae, new species, is described from two specimens captured off Brazil. It is distinguished from congeners by the following characters: origin of the first dorsal fin anterior to pelvic-fin origin, presence of well-developed upper and lower caudal crests of denticles, dorsal fins subequal, lateral denticles teardrop-shaped and lacking lateral cusplets, denticles evenly spaced, proportional dimensions, and vertebral counts. Parmaturus angelae, new species, is the second species of the genus reported from the Atlantic Ocean and only the third species outside of the Indo-West Pacific region. Parmaturus remains rather poorly defined as only two species have been studied anatomically in any detail.
