Neanthes cricognatha (Ehlers, 1904) 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.
