Type material. Holotype not located, paratypes (BMNH ZK 1961.9.480/ 1).
Records. USA: off Florida and Texas, 15–90 m, coarse to fine sand (Johnson, 1984). Cuba: Batabano (Ibarzabal 1986).
Remarks. The presence of Aonidella cirrobranchiata (Day, 1961) in the Grand Caribbean is questionable. Specimens of Johnson (1984) and Ibarzabal (1986) require examination, because these specimens differ from A. cirrobranchiata (Day, 1961), in having a slight medial indentation on the prostomium, four eyes instead of none, and hooded hooks with 2–4 apical teeth instead of one.
