Apodotrocha progenerans n.gen., n.sp. from tidal beaches or shallow waters on the east coast of the USA (Massachusetts) is a gonochoristic interstitial polychaete (length ca. 600 ?m; six trunk segments), that lacks parapods, setae, and fleshy appendages, but has three characteristic caudal cirri. The habitus greatly resembles a larval stage of the Dorvilleidae, a family with which it also shares several anatomical features as revealed by ultrastructural investigations. Great similarities to the so-called archiannelids belonging to the Dinophilidae are also apparent, thus demonstrating the close phylogenetic relationship of the latter family to the Dorvilleidae.
