The monophyly of Magelona F. Müller, 1858 (Polychaeta, Magelonidae): Comments on Meißner et al.'s (2023) reinstatement of Octomagelona Aguirrezabalaga, Ceberio & Fiege, 2001.

The first published phylogenetic hypotheses involving members of the polychaete taxon Magelonidae Cunningham & Ramage, 1888, were reported by Mortimer et al. (2021), wherein results showed that for the two genera in the family, Magelona F. Müller, 1858, was paraphyletic relative to Octomagelona Aguirrezabalaga, Ceberio & Fiege, 2001.

Redescription of Naineris aurantiaca (Müller, 1858) and designation of a neotype from the Brazilian coast (Annelida: Orbiniidae).

The genus Naineris differs from other genera of the Orbiniidae in that all its species possess a rounded prostomium and one or two achaetous rings. Currently, 21 species of this genus have been described worldwide, five of which are recorded from Brazil. Naineris aurantiaca is the only species originally described from the Brazilian coast and the original description is the only record of this species.
