Leitoscoloplos sp. 1 Fig. 18D

Diagnosis.

Incomplete specimen, 17 mm long, 1.9 mm wide. Thorax slightly flattened, abdomen cylindrical. First nine segments short, then becoming longer. Fourteen thoracic chaetigers, last one intermediate. Prostomial sharp conical; one peristomial ring. All thoracic segments and at least first three abdominal segments without branchiae. Thoracic postchaetal lobes short conical in both rami, notopodial lobes slightly longer. No subpodial or stomach papillae. Thoracic noto- and neurochaetae long crenulated capillaries. Abdominal region macerated; chaetae broken. Shape of abdominal parapodia and chaetae unknown. Colour in ethanol brown-yellowish.

Remarks.

This specimen is similar to L. abranchiatus but has more thoracic chaetigers and shorter thoracic postchaetal lobes. Two OTUs assigned to Leitoscoloplos (four stations, 486-2224 m) were recorded in the GAB ( MacIntosh et al. 2018: additional file 2), but further investigation is required to determine if any of the species from this study match those from the GAB.

Records.

1 specimen. Suppl. material 1: op. 30 (AM).
