WoRMS note details

ISO 639-3eng
NoteIdentity uncertain? Invalid as a homonym but the taxon was questionably referred to be a synonym of Spio filicornis (Müller, 1776) by Soderstrom (1920). However, 1) McIntosh erected this name for Spio filicornis sensu Malmgren, and 2) there are multiple Spio species similar to S. filicornis in Europe.
