REMARKS

Poecilasma aurantia was first described from Madeira, and recorded elsewhere from the eastern Atlantic. Young (1998a: 5, b: 33) considered this species distinct from P. kaempferi which is known to occur in the western Pacific region. The validity of the species of Poecilasma has yet to be reevaluated.
