Harmothoe indet.

Diagnosis.

Single specimen, broken, with 37 segments, missing elytrae. Fifteen pairs of elytrophores on 2, 4, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 26, 29, 32. Palps smooth. Prostomium with prominent cephalic peaks. Two pairs widely spaced large eyes, anterior ones laterally located, posterior ones also laterally placed. Median antenna with large ceratophore, style papillated and longer than palps, lateral antenna short, inserted ventrally, bases separated. Lateral antennae styles papillated, short, approximately half length of prostomium. Prostomium pigmented (brown). Tentacular segment with notochaetae. Dorsal cirri styles papillate, tapering. Notochaetae slightly thicker than neurochaetae. Notochaetal bundles held erect but not meeting dorsally. Notochaetae with rows of spines to tip. Neurochaetae slenderer, with rows of spines, medially inflated, and fine bidentate bare tips (secondary tooth small). Neuropodial acicular lobe with small distal digitiform lobe. Notopodial lobe with elongate acicular lobe.

Remarks.

As elytra are all missing, this specimen could not be identified to species. It does not resemble Harmothoe sp. 5 of this survey or any of the Harmothoe species found in the GAB surveys.
