Material examined: Ceará —2 M, Parque Estadual Marinho da Pedra da Risca do Meio , associated with Callyspongia (Cladochalina) aculeata ( Linnaeus 1759) , 22.0 m depth, MOUFPE 18389 ; Rio Grande do Norte — Natal: 1 M, Almirante Saldanha Expedition , St. 1657, 08.x.1967, 05°33.4′S 35°0.02′W, 52.0 m depth, MOUFPE 8778 .

Description: Coutière (1909), Verrill (1922), and Anker et al. (2012).
