Ceratonereis japonica Imajima, 1972 View in CoL

Ceratonereis japonica Imajima, 1972: 69 View in CoL –71, figs 15a–p, 17.

Material examined. NTM: W23995 (1), Channel bommies, 14°41.3088'S 145°27.8339'E, coll. CReefs Lizard 10 Team, 25 Aug 2010.

Comparative material examined. NTM: W25885 (1), W25884 (1), Tanjung Merah, Bitung, North Sulawesi, Indonesia, 1°27'N, 125°12'E.

Diagnosis. Ceratonereis species having rod-like paragnaths arranged in eight groups in maxillary ring (Areas I: 6 in single cluster; II: 6–8 in single cluster on each side; III: 5 in each of 3 clusters; IV: 3 in single cluster on each side (but some paragnaths apparently missing as a result of damage); oval-shaped yellow glands at base of dorsal cirri chaetigers.

Remarks. The present specimen, which is epitokous, corresponds with the description of Imajima (1972), particularly in the arrangement of paragnaths in eight groups in the maxillary ring, which sets it apart from other Ceratonereis and allies it more with Solomononereis . Indeed this species shows intermediate characteristics between Ceratonereis and Solomononereis : like members of Ceratonereis it is large-bodied, has a deeply-cleft anterior prostomium and large postchaetal neuropodial lobes, but like the latter it has rod-like paragnaths (Imajima refers to them as cones, but his illustrations are indicative of rods) and oval-shaped yellow glands at the base of dorsal cirri chaetigers. Because of these similarities Nateewathana (1992) suggested that the original material of Ceratonereis japonica Imajima, 1972 should be re-examined to determine whether it should be included in Solomononereis . As the two genera were shown by Bakken & Wilson (2005) to be sister groups, then a more inclusive systematic study is required to investigate the taxonomic position of species.
