Sigambra sp. 1

Diagnosis.

Small specimen, complete, 47 chaetigers. Pharynx with eight or nine terminal papillae. Dorsal cirri (except for first) slightly longer than ventral cirri. Dorsal hooks starting from chaetiger 3, extending to within a few segments from pygidium; accompanied by one or two small capillary chaetae. Neurochaetae smooth, broad-bladed capillaries of varying lengths. Chaetiger 2 with ventral cirri. Median antenna much longer than laterals, extending back to chaetiger 6; first dorsal cirri cirriform, several times longer than following ones which are slender, foliose. Colour in ethanol white.

Remarks.

The specimen is similar to S. magnuncus Paterson & Glover, 2000. It probably represents a new species.
