Prionospio steenstrupi Malmgren, 1867 Prionospio steenstrupi Malmgren, 1867: 202.— Augener, 1906.— Foster, 1971a: 84.— Sigvaldadóttir & Mackie, 1993: 204 – 207, figs 1–2, 5, table 1–2.— Bone & Viéitez, 2002: 72. Prionospio ( Prionospio ) steenstrupi .— Maciolek, 1985: 332 –335, fig. 1.— Johnson, 1984: 6.47– 6.49, figs 6.37–6.38. Type locality. Iceland (65°53’N, 19°27’W), 73 m, clay. Type material. Syntypes (NHRM 3170). Records. USA: Florida (Foster 1971a); Alabama, Texas (Johnson 1984). Venezuela: Morrocoy (Bone & Viéitez 2002). Remarks. Sigvaldadóttir & Mackie (1993) redescribed this species and noted additional distinguishing features. They mention that the species only occurs off Iceland. All records of this species for the Grand Caribbean are questionable. Foster (1971) presented a description of Prionospio steenstrupi based on material from Alaska, Canada and the east coast of the USA. Foster’s specimens differ of P . steenstrupi in the shapes of second and third pairs of branchiae, and shapes of anterior neuropodial lamellae, also dorsal crests are present on setigers 6 to 16–18 and, in some specimens are present on chaetigers 15–25, and in other specimens crests are absent. We believe that the specimens recorded for the Grand Caribbean as P. steenstrupi Malmgren, 1867 represent a new species.
