One additional worm that deserves mention is Flout flubelligera, another pelagic polychaete. Hartman (1967) initially con- sidered it a tlahelligerid, hut she later transferred it to Fauveliopsidae (1971). Recently, Plot a has been considered to be closely related to taxa in Terebellida and especially to Poeobius (Rouse and Pleijel, 2001, 2003). Under the Lin- nean system, Flotu is still considered a separate family. Neither F. flabelligera nor P. me seres is known to have a fossil record. To our knowledge, a formal phylogenetic hypothesis has never been proposed for relationships within Flabelligeri- dae. The first flabelligerid (Amphitrite plnmosn. now Phentsa plumosa) was formally described in 1776 by Miil- ler. and the family was erected in 1894 by Saint-Joseph. The current taxonomic scheme for the group is based largely on the works of Haase (1915), Fauvel (1927). Stop-Bowitz (1948). Day (1961. 1967). and Hartman (1961, 1969). Re- cent morphological cladistic analyses (Rouse and Fauchald, 1997; Rouse and Pleijel. 2001) place Flabelligeridae within Cirratuliformia, Terebellida. and Canalipalpata. Relation- ships within this putative clade (also including Acrocirridae. Cirratulidae. Ctenodrilidae. Fauveliopsidae. Poeobiidae. and Sternaspidae) remain unclear. With the recognition of Poeobiidae Heath 1930. the monophyly of Flabelligeridae has been called into question. There are morphological similarities between these two groups, such as the presence of a retractable head, a pair of grooved palps, an anterior ring of branchiae, and a gelati- nous mucus sheath, although some of these features are not exclusive to these taxa.
