1992
Anuwat Nateewathana
Monotypic species Solomononereis marauensis Gibbs, 1971 has been reported from polyhaline environments in Solomon Islands, South Pacific and in the northern Australia. Samples from fully marine sea beds on the west coast of Phuket Island, Andaman Sea, have revealed one more species, described as Solomononereis phuketensis. It differs from S. marauensis in having notosetal falcigers present in most anterior setigers. Dorsal ligules are digitiform and greatly reduced already in the anterior part of the body. Paragnaths are slender conical against rod-shaped (pegs) in S. marauensis. Conspicuous glands at the base of the dorsal cirri are characteristic of both species of the genus and may constitue a unique character of the genus. The two species of Solomononereis share a number of characters with Ceratonereis japonica Imajima, 1972. A comparison of these three closely related species is given.
