We used morphological data for a phylogenetic analysis of the genus Petaloptoctus (Maldanidae: Polychaeta). We found three most parsimonious phylogenetic trees with length = 37, CI = 0.89 and RI = 0.92. The genus Petaloproctus is monophyletic, and is supported by a strongly arched prostomium, pinnate capillary setae, and an anal cup with a reduced dorsal border. Our proposal for the systematisation of the subgroups of Petaloproctus is (( P. tenuis ( P. terriculus + P. neoborealis )) ( P… Expand
