REMARKS

Acasta cyathus is a common species found associated with several species of sponges along all the tropical oceans. Young (1995) recorded this species as ranging to 18°S from Brazil. The new samples show a wide tropical South Atlantic distribution of this species from 8°S to 18°S. It is presently the only species of Acasta found along the Brazilian coast.
