PROC. BIOL. SOC. WASH. 96(2), 1983, pp. 238-249 A REVISION OF THE BOGUEIDAE HARTMAN AND FAUCHALD, 1971, AND ITS REDUCTION TO BOGUEINAE, A SUBFAMILY OF MALDANIDAE (POLYCHAETA) Paul S. Wolf Abstract. — Boguea enigmatica Hartman, 1945, is redescribed and its known range extended. Notes on its larval development are presented. The description oi Boguella ornata Hartman and Fauchald, 1971, is emended. Based on these revisions, the family Bogueidae is reduced to Bogueinae, a subfamily of Maldan-idae based on morphological and ontogenetic criteria. Keys to the subfamihes of Maldanidae , modified from Fauchald (1977), and to the genera of Bogueinae are given. Hartman (1945) first described Boguea enigmatica from Bogue Sound, North Carohna, as a member of the Oweniidae. Hartman and Fauchald (1971) later described Boguella ornata from deep waters off the coast of New England, at which time they also erected the family Bogueidae with Boguea as the type-genus. Boguea enigmatica and Boguella ornata have not been recorded outside of their type-locahties. Superficially the Bogueidae are unique among the polychaetes in possessing avicular (terebelloid) uncini and yet lacking the head modifications typical of other families with avicular uncini (e.g., Terebellidae, Ampharetidae, Sabellidae, and Pectinariidae) . However, the following redescription of Boguea enigmatica and emended description of Boguella ornata show that the Bogueidae share many morphological and ontogenetic characters with the Maldanidae; therefore, Bo-gueidae is reduced to a subfamily of the Maldanidae. Due to the apparent disagreements in definitions of life stages (see Bookhout and Horn 1949, and Hermans 1979, for example), it is necessary to define the criteria used in this paper for separating larvae, juveniles, and adults. Specimens are considered larvae if they still contain some yolk material. Depending upon the stage of development, larvae may or may not possess rostrate uncini. Larvae examined range from 2 to about 16 setigers long. Ciliated bands were not seen on any of the larvae examined. Specimens are considered juveniles if they lack yolk material, yet still possess the rostrate uncini in the anterior setigers. Juve-niles range from about 15-23 setigers. Adults are those individuals lacking rostrate uncini (except perhaps in far posterior setigers), and ranging from about 23-30 setigers. It should be noted that the above life-stage distinctions pertain only to Boguea enigmatica as it is described in this paper. Bogueinae, new rank Oweniidae (in part) .^Hartman, 1945:42.
