Taxonomy In the original description of Nereis maxillodentata, Hutchings & Turvey (1982: 93) state "[...] Nereis is partly identified by paragnaths in both oral and maxillary rings. Nereis maxillodentata n.sp. lacks oral paragnaths and possesses notopodial falcigers. Hence it should be placed in Ceratonereis, although its affinities are clearly with N. bifida n.sp., and it has been placed in Nereis for that reason." In her partial revision of the genus Ceratonereis, Hartmann-Schröder (1985) does not make any comment on the species, but in a posterior work (Hartmann-Schröder, 1989: 35) she places the species under the new combination Ceratonereis (Composetia) maxillosa, arguing that "Paragnathen am oralen Ring (V-VIII) völlig fehlend. Darum muß die Art in die Gattung Ceratonereis überführt werden, und zwar in die Untergattung Composetia, da nur zusammengesetze Borsten vorhanden" [= "Paragnaths on the oral ring (V-VIII) completely absent. Therefore, the species must be transferred to the genus Ceratonereis namely in the subgenus Composetia, as only composed chaetae are present"]. The species, however, has been normally considered to belong to the genus Nereis, and its possible belonging to the genus Ceratonereis was never discussed again. In the phylogenetic analysis based on morphologic characters performed by Bakken & Wilson (2005), the species forms a clade with Nereis bifida Hutchings & Turvey, 1982, with Nereis cockburnensis Augener, 1913 nesting as a sister group to the clade. So, the species is here maintained in the genus Nereis, with the combination Ceratonereis (Composetia) maxillodentata being considered as an alternate representation. [details]
