WASH. 105(3), 1992, pp. 589-613 PHYLLODOCIDS (ANNELIDA: POLYCHAETA) OF BELIZE, WITH THE DESCRIPTION OF THREE NEW SPECIES Danny Eibye-Jacobsen Abstract. — Phyllodocidae (polychaetes) from Belize are reported. Eight spe-cies are treated in detail. Of these, 3 are newly described: Eumida muriatica, Sige belizensis, and Nereiphylla mi mica. Pterocirrus foliosus (Treadwell, 1924) is redescribed and the identities of Hesionura elongata (Southern, 1914), Mys-tides borealis Theel, 1879, and Phyllodoce erythrophylla (Schmarda, 1861) are discussed. Eight additional species are recognized, but not treated in detail due to the lack of sufficient material. Together with the previously recorded Phyl-lodoce panamensis Treadwell, 1917, 17 species are now known from Belize. The presence of a Smithsonian field sta-tion on the island of Carrie Bow Cay in Belize has led to great improvements in our knowledge of the polychaete fauna of the western Caribbean Sea. Notable taxonomic contributions are by Fauchald (1980, Onu-phidae), Fitzhugh (1983, Sabellidae), Young & Kritzler (1987, Terebellidae), Russell (1989a, 1989b, Syllidae), and Solis-Weiss & Fauchald (1989, Orbiniidae). To date, the only published account of the Phyllodocidae of Belize is by Young & Young (1982), who reported the presence of three species: Phyllodoce (Anaitides) pa-namensis Treadwell, 1917, Hesionura elon-gata (Southern, 1914) and Eulalia viridis (Linnaeus, 1767). During October and November of 1988 I visited Carrie Bow Cay. Several species of phyllodocids were collected, three of which were found to be new to science. This prompted the study of previously collected, undetermined phyllodocid material held at the National Museum of Natural History, Washington, D.C. (USNM). Sixteen species were found, eight of which are treated in detail below. Materials and Methods The 1988 collections were made near the following islands: Carrie Bow Cay, South Water Cay, Tobacco Cay, the Cocoas (east of northern end of Blue Ground Range), and the Sand Bores (east of the Cocoas). Earlier collected material had also been taken near Twin Cays and at Glover's Reef (for the locations of these islands see Rutzler & Macintyre 1982). Details on all stations are given in the appendix. For the individual species below, material examined (for Be-lizean animals only) is indicated by the sta-tion numbers, in each case followed by the number of specimens from that station in parentheses. Data on non-Belizean material used for comparative purposes are given in the remarks section where appropriate. Coral samples taken in 1988 each con-sisted of approximately 3.5 1 of coral rubble with a drained weight of about 4.5 kg. Rub-ble was mechanically broken into smaller pieces and shaken in seawater to obtain live specimens. The pieces were then placed in a large bucket of seawater to which a few drops of clove oil were added. After about 1 2 hours, each sample was fixed in buffered 2% formalin. Individual pieces of coral rub-ble were subsequently washed in another bucket of seawater, where obvious speci-mens were removed with forceps, and the contents of both buckets then filtered through a 200 /im sieve. The material was once again fixed in 2% formalin and two
