Revision of the genus <i>Micronereis</i> (Polychaeta: Nereididae: Notophycinae)

World Polychaeta Database (WPolyDb)
The genus Quadricirra Banse, 1977 is not recognized, since its principal diagnostic character, the presence of accessory parapodial cirri, is sexually dimorphic and cannot be correlated with other characters; thus Micronereis is the sole genus of the subfamily Notophycinae. A new species, M. piccola, is described and M. siciliensis and M. bodegae are synonymized with M. variegata and M. nanaimoensis respectively. A key to males and descriptions of all species are provided. The Notophycinae appears to be the most derived subfamily of Nereididae, characterized by a combination of epitokal modifications retained from their nereidid relatives and specializations acquired as members of the meiofauna.
