Abstract

Based on features of the holotype and seven Brazilian specimens examined under stereomicroscope, light microscope, and scanning electron microscope, Eunice rubra Grube, 1856 is redescribed, allowing for intraspecific variation and providing informationon characters not included in a previous redescription. Characters important for the taxonomy of the genus varied widely, although in some cases because of fixation artefacts.
