Neanthes sp. 1 Fig. 15C, D

Diagnosis.

Antennae ~ one quarter length of prostomium. Longest tentacular cirri extending back to chaetiger 5-6. Area I = 13; II ≥ 30; III ≥ 30; IV> 30; V absent; VI = 6; VII-VIII = 51. Prechaetal notopodial lobe present; approximately equal to length of dorsal notopodial ligule at least on anterior chaetigers (thus notopodium of three similar sized ligules/lobes); present throughout all chaetigers. Dorsal cirrus length ~ 1 × acicular notopodial ligule at chaetiger 10-20. Neuropodial prechaetal and postchaetal lobes absent. Neuropodial postchaetal lobe present, at least on some anterior chaetigers; projecting strongly beyond end of acicular ligule throughout all chaetigers. Ventral neuropodial ligule of anterior chaetigers ~ as long as acicular neuropodial ligule. Notopodia larger than neuropodia, dorsal notopodial ligule prominent triangular, largest structure in the parapodia.

Notopodial homogomph spinigers present. Neurochaetae: dorsal fascicle homogomph spinigers only (heterogomph falcigers absent). Neurochaetae, ventral fascicle: heterogomph spinigers absent. Homogomph spinigers present, heterogomph falcigers absent.
