First new Dodecaceria (Polychaeta: Cirratulidae) species from the SW Atlantic (38ºS - 57ºW, Argentina)

ABSTRACT Cirratulids are a difficult group because they have a few taxonomic characters and these are often misinterpreted. The genus Dodecaceria, in particular has been reviewed in several parts of the world but not in the southwestern Atlantic shore. The benthic surveys of organically enriched are...
