Redescription of two Phyllodoce (Annelida: Phyllodocidae) species from Hawaii

Abstract

ABSTRACT The two endemic Hawaiian phyllodocid species Phyllodoce hawaiia (Hartman, 1966) and P. hiatti Hartman, 1966 are only known from the original description. A redescription based upon type material helped clarify the taxonomic status of these species and to confirm the synonym of Prophyllodoce Hartman, 1966 with Phyllodoce Lamarck, 1818. Phyllodoce hawaiia is characterized by having a strongly cordate prostomium, proximal region of proboscis with 20 rows of round papillae and distal region with six longitudinal rows of tubercles, tentacular cirri with short and ringed cirrophores and long cirrostyles and parapodial prechaetal lobes bilobed and asymmetrical. Phyllodoce hiatti has an oval prostomium, papillae diffusely distributed in proximal region of proboscis, tentacular cirri with well-developed cirrophores, prechaetal lobes bilobed, round and symmetrical and rounded dorsal cirri.
