Melinnopsis spp. nov. Fig. 4G

Diagnosis.

Minute acicular chaetae present on segments II-V. One long buccal tentacle present, diagnostic of genus. Four pairs of branchiae. Colour in ethanol pale yellow. Many specimens, but usually in poor shape.

Remarks.

At least two species of Melinnopsis are present. Further molecular investigation is required to delineate species. Some specimens are near to Melinnopsis tetradentata (Imajima, 2001) described from 621-622 m depth in Tosa Bay, Japan, but further investigation of type material is required to confirm their identity.

Records.

112 specimens. Suppl. material 1: ops. 4, 6, 14, 22, 30, 43, 44, 56, 69, 80, 90, 101, 104, 121, 122 (AM).
