Caryophyllia diomedeae Marenzeller, 1904: 79–80 , pl. 1, fig. 2. — Cairns, 1991: 11–13, pl. 4c–e (description, figures); 1995: 49–50, pl. 9, figs. a–d (synonymy, description, figures). — Cairns & Zibrowius, 1997: 88–89 (synonymy, diagnosis, key). — Piñón, 1999: 20, 81 (listed). — Cairns, 2004: 277 (synonymy).

New Record. — Anton Bruun 17­673G, 21°31'S, 81°31'W ( Nazca Ridge off northern Chile), 1760 m, 9 Jul 1966, 2 specimens, USNM 83522 .

Remarks. —Compared to the type, the single intact specimen figured herein differs in having a slightly flared and thickened calicular edge and a deeper fossa, although subsequently reported specimens (see synonymy) include this range of variation. The figured specimen is 16.3 x 15.7 mm in CD and 23.4 mm in height, with a slender pedicel diameter of 3.9 mm. It has a full four cycles of septa and 12 P3, as previously described for this species.

C. diomedeae is widely known from the Pacific Ocean from Panama to Tasmania at depths of 225–2200 m (Cairns in press). It was previously reported from the eastern Pacific off Panama at 1043 m (the type locality) by Marenzeller (1904), the Galápagos at 245–806 m by Cairns (1991), and from 0°– 31°S at 55–2086 m by Piñón (1999), although the last record was meant to read 0– 31° N (Pinon, pers. comm., 2004).
