Laubieriopsis hartmanae (Levenstein, 1970) Fig. 9A-C

Diagnosis.

Prostomium retracted. Body linear, blunt on both ends with 16 chaetigers. Chaetigers 1-4 shorter with 2-3 large acicular chaetae and 2-3 small acicular chaetae per parapodia. Chaetigers 5-16 with one acicular and one capillary per ramus, longest on chaetiger 16. Granular genital papillae on boundary of chaetigers 6 and 7.

Remarks.

Similar in appearance to L. brevis from the Atlantic Ocean, but differs in the tips of the aciculars (bidentate in L. brevis ) and genital papilla (smooth in L. brevis ) ( Salazar-Vallejo et al. 2019b). One species of Laubieriopsis was recorded from five stations (932-4068 m) in the GAB ( MacIntosh et al. 2018: additional file 2); however, further investigation is required to determine if the species in the present study are the same as at the GAB.

Records.

22 specimens. Suppl. material 1: ops. 9, 16, 23, 40, 42, 45, 76, 79, 96, 110, 134 (NHMUK). 2 specimens. Suppl. material 1: op. 79.
