Bathyglycinde profunda (Hartman & Fauchald, 1971) Fig. 11B, D, E

Diagnosis.

Up to 24 mm length and 69 segments; anterior 36-37 parapodia uniramous; prostomium indistinctly annulated with bi-articulated terminal appendages; eyes absent; chevrons not present; papillae on pharynx arranged in rows (Fig. 11E ); parapodia biramous at least at posterior part of body; notochaetae capillaries; one posterior neuropodial lobe.

Remarks.

A Depth range of 350-5500 m has been reported ( Böggemann 2005).This species was previously recorded from a single station, 2063 m, in the GAB ( MacIntosh et al. 2018: additional file 2). Bathyglycinde profunda was originally described from the equatorial region off northeast South America (4825 m) ( Hartman and Fauchald 1971); however, molecular evidence suggests it is a widespread deep-water species ( Böggemann 2009).

Records.

7 specimens. Suppl. material 1: ops. 16, 31, 33, 54 (AM). 3 specimens. Suppl. material 1: ops. 31, 103, 134 (NHMUK).
