Comparative material examined. NTM: W23797 (1), W23804 (1), Ambon, Maluku, Indonesia. ZMA: Neanthes gisserana ( Horst, 1924) VPol 0 854 (2 syntypes), R/V Siboga Station 172, Gisser anchorage, between this island and Seram-Laut, Maluku, Indonesia, 18 m, coll. 26 Aug 1899.

Diagnosis. Neanthes species having transverse brown bar on dorsal surface of chaetiger 4; two notopodial ligules in anterior parapodia; both bar-shaped and conical paragnaths in Area IV (bars are adjacent the jaws), and one row of 4–6 paragnaths in Area III.

Remarks. The specimens examined here are similar to Neanthes gisserana and apparently identical with specimens from Ambon described by Pamungkas & Glasby (2015). The present material was compared to the epitokous syntype specimens, and agrees closely at least in terms of features not altered by the epitoky. Thus paragnath numbers and pattern correspond closely, especially the presence of bars adjacent the jaws in Areas IV, which Monro (1939) referred to as the ‘most remarkable character of the species’. Here the species is given a cf. designation because it departs from the type most notably in the paragnath arrangement in Area III, which is 3–4 rows of 16–26 paragnaths across three groups in N. gisserana . It may represent a new species.

Unfortunately, photographs of specimen AM W.43844 (field no. 2342) have been misplaced, so an image record of this common species is lacking. Comparative specimens from Ambon, Indonesia (NTM W23797, W23804) have a transverse brown bar on the dorsal surface of chaetiger 4, and other irregular brown mottling on the anterior end. Horst (1924) noted a red-brown buccal segment, blackish pigment on the prostomium and narrow transverse blackish stripes on the anterior part of each segment.

Habitat. Lagoon, fore-reef and reef slope, 1– 30 m.

Type locality. Between Gisser and Seram-Laut, Maluku, Indonesia.

Distribution. Eastern Indonesia, Lizard Island.
