Ordo: Aciculata
Familia: Nereididae
Name
Platynereis Kinberg, 1865 – Wikispecies link – Pensoft Profile
Includes
Iphinereis Malmgren, 1865; Pisenoë Kinberg, 1865; Leontis Malmgren, 1867; Nectonereis Verrill, 1873; Uncinereis Chamberlin, 1919.
Type species
Platynereis magalhaensis Kinberg, 1865, by subsequent designation (Hartman 1948[1])
Diagnosis
(after Read 2007[2], emended). Proboscis with chitinous paragnaths in form of parallel, tight rows of minute rods usually present on all areas except I, II and V. Prostomium with 2 antennae, biarticulate palps and 2 pairs of eyes; 4 pairs of tentacular cirri. Peristomial segment apodous and first 2 parapodia sub-biramous. Chaetae include spinigers and falcigers. Homogomph notopodial falcigers usually present, in least in juveniles.
Remarks
The above description is emended with respect to the paragnath terminology introduced by Bakken et al. (2009)[3]. However, it should be noted that Bakken et al. (2009)[3] only confirmed the form of paragnaths as tight rows of rods, as opposed to the previously described pectinate bars, for 3 species of Platynereis that did not include Platynereis magalhaensis. This is now, however, confirmed for Platynereis magalhaensis below.
