Cheiraster sepitus (Verrill, 1885) — Harvey et al. 1988: 160–161; García-Diez et al. 2005: 47.
Type locality: S of Cape Sable, Nova Scotia, USA.
See: A.M. Clark (1981); A.M. Clark & Downey (1992); Benavides–Serrato et al. (2011).
Occurrence: North Atlantic, from Nova Scotia south to the Caribbean (A.M. Clark 1981), east from west of Iceland (A.M. Clark & Downey 1992) and the Rockall Trough (Harvey et al. 1988) southwards to the Cape Verde area including the Azores (Koehler 1909).
Depth: 304– 3,706 m (Benavides–Serrato et al. 2011), mostly 1,000 –2,000 m (A.M. Clark 1981); AZO: 1,165 – 3,706 m (Sladen 1889).
Habitat: soft bottoms, muddy sand to ooze (Koehler 1909).
Remarks: the inaccurate original description of the type material by Verrill (1885a) and subsequent multiplicity of synonymies resulted in an unclear geographical and bathymetric range for Cheiraster sepitus (A.M. Clark 1981; A.M. Clark & Downey 1992).
