Abstract
Some of the intriguing issues in current polychaete systematics are reviewed. (1) The root of the `polychaete' tree. Currently there are two major hypotheses concerning the root position among polychaetes. One is based on rooting cladograms with outgroups such as Mollusca and result in simple-bodied taxa such as Opheliidae and Questidae forming a basal annelid grade along with Clitellata. Other hypotheses do not use outgroup rooting but involve scenarios on the evolution of the group and would place taxa in Aciculata as basal annelids, thus making Aciculata and Phyllodocida paraphyletic. Molecular sequence data has been of little help in resolving this issue thus far, largely due to limited taxon sampling. (2) Paraphyly. Owing, in part, to a tradition involving the emphasis on differences among taxa, and the application of Linnean ranks (e.g., family), paraphyly is undoubtedly a widespread phenomenon in polychaete systematics. An example of this has been proposed already for Spionidae. If the tree topology and rooting used by Blake & Arnofsky (1999) is correct, Spionidae is made paraphyletic by the recognition of the following four family-ranked taxa; Trochochaetidae, Poecilochaetidae, Longosomatidae and Uncispionidae. Another possible example is seen with Cirratulidae. A preliminary cladistic analysis shows that it is entirely possible that seven other taxa recognised as families may be nested within Cirratulidae. These include Acrocirridae, Ctenodrilidae, Fauveliopsidae, Flabelligeridae, Flotidae, Poeobiidae and Sternaspidae. (3) Problematic taxa. Apart from the problems exposed by the analysis of Cirratuliformia, the position of some of these groups, such as Aberranta, Alciopidae, Hesionides,Lopadorhynchidae, Microphthalmus,Nerillidae, Spinther,Tomopteridae and Sabellariidae, is discussed.
