Material examined. Two specimens, 180.0–235.0 mm TL: USU 0 1405 (1, 180.0 mm, x-rayed), MD, 64 CB 105; MNHN 1989 - 349 (1, 235.0 mm, x-rayed), MD, 64 CB 105.
Distribution. Acromycter atlanticus is being reported for the first time in the WSA. It was described from the Caribbean Sea, and is also known from off the coast of Florida, USA (Smith 2002).
Remarks. Diagnosis of Acromycter atlanticus from A. perturbator was made based on vertebral counts (167 to 171 in A. atlanticus vs. 159 to 164 in A. perturbator). Also, A. atlanticus is known to inhabit shallower regions (from 500 to 650 m) than A. perturbator (about 1,300 m) (Smith 1989 b). Both specimens examined were reported by Séret and Andreata (1992) as A. perturbator; other specimens reported by them as A. perturbator were correctly identified.
