Lumbrineris de Blainville, 1828

Type species.

Nereis ebranchiata Pallas, 1788

Diagnosis

(after Carrera-Parra (2006b)). Prostomium without antennae, without eyes. Maxillary apparatus with five pairs of maxillae, carriers as long as MI, joined along entire base of MI; MI forceps-like without inner accessory teeth, with attachment lamella; MII as long as MI, with ligament, with attachment lamella well developed along 2/3 of lateral edge; with wide connecting plates slightly developed; MIII completely pigmented, with attachment lamella well developed along entire lateral edge; MIV completely pigmented, with attachment lamella well developed; MV free, reduced just to attachment lamella, lateral to MIV and MIII. Mandible fused up to 3/4 of its length. Parapodia with dorsal cirrus slightly developed; without branchiae. Chaetae limbate capillaries and simple and compound multidentate hooded hooks. Pygidium with anal cirri.

Remarks.

Lumbrineris is the most species rich of lumbrinerid genera. It has a long and confused taxonomic history, summarised in the most recent review carried out by Carrera-Parra (2006b), who also provided an updated and restricted definition of this genus, recognising only ~ 35 species as valid. However, it is important to state that according to G. Read (Read in fide 2019 in Read and Fauchald 2022b), many studies, including that of Carrera-Parra (2006b), have cited incorrect type species for this genus; the correct type species is Nereis ebranchiata Pallas, 1788 now accepted as Lumbrineris ebranchiata (Pallas, 1788), a species that Carrera-Parra (2006b) did not recognise as Lumbrineris . Solving such taxonomic difficulties is beyond the scope of this study and for practical reasons, we follow the definition as given by Carrera-Parra (2006b). One species consistent with the genus Lumbrineris has been found in our CCZ samples.
