Ophelina cf. helgolandiae Augener, 1912 View in CoL Fig. 17D, E View Figure 17

Diagnosis.

Prostomium triangular, longer than wide with oval palpode. Four annuli on prostomium revealed using Shirlastain. Eyes absent. 32 chaetigers. Chaetigers 2-7 having more abundant chaetae. Chaetigers 25-32 ventrally located and compressed. Branchiae on chaetigers 2-5, then on chaetigers 25-32. Anal funnel slightly longer than the last two posterior chaetigers, directed dorsally, with thickened ventral keel and small terminal cirri.

Remarks.

Observed specimens closely resemble Ophelina helgolandiae Augener, 1912, which is recorded from the Nordic Seas at depths of 600-1300 m ( Kongsrud et al. 2011), but differ in having a pointed, annulated prostomium and lacking branchiae in the midbody chaetigers.
