N2 - The jaw ontogeny of Dorvillea albomaculata and D. bermudensis was studied in cultured specimens, reproducing asexually by transverse fission. Mandibular growth was found to occur by lateral apposition. Maxillary development exhibited a gradual growth pattern, as opposed to the maxillary moults found in closely related species (Macnaughton et al. 2009). Details of dentition and numbers of maxillary plates as well as the ontogenetic growth patterns of the jaws were found to provide significant information of systematic value. Based on detailed studies of jaw ontogeny and morphology, Dorvillea albomaculata and D. bermudensis are here reassigned to the genus Parougia (Dorvilleidae, Annelida). This is supported by the external morphology as well as previous molecular studies. (C) 2011
