Neanthes cricognatha (Ehlers, 1904) View in CoL Fig. 15A View Figure 15

Diagnosis.

Prostomium with entire anterior margin. Longest tentacular cirri extend back to chaetiger 4. Maxillary ring of pharynx without papillae. Area I = 9-16; II = 22-45; III = 23-45 paragnaths; IV = 29-54; V, VI, VII-VIII forming a dorsally and ventrally continuous ring.

Notopodial prechaetal lobe present, well developed, so that notopodium made up of two ligules and one lobe similar and triangular. Dorsal cirrus length ~ 1 × ventral notopodial ligule at chaetiger 10-20. Neuropodial postchaetal lobe present, at least on some anterior chaetigers. Ventral neuropodial ligule on posterior chaetigers similar to length of acicular neuropodial ligule. Ventral cirri single.

Notopodial homogomph spinigers present; sesquigomph spinigers absent. Notopodial homogomph falcigers absent. Neuropodial dorsal fascicle fused falcigers absent.

Remarks.

At 1194-1257 m, this is the deepest record of this species which is widely distributed in Australia and New Zealand from the intertidal to 253 m, suggesting this may be a species complex.
