Abstract

We produced two new EST data sets of so far uncovered clades of ectoprocts to investigate the relationships within the lophophorate lineages, Ectoprocta, Brachiopoda and Phoronida. Maximum-likelihood analyses based on 78 ribosomal proteins of 62 metazoan taxa support the monophyly of Ectoprocta and a sister group relationship of Phylactolaemata living in freshwater and the mainly marine Gymnolaemata. Hypotheses suggesting that Ectoprocta is diphyletic with phylactolaemates forming a clade with phoronids or paraphyletic with respect to Entoprocta could be rejected by topology tests. The hypotheses that Stenolaemata are the sister group of all other ectoprocts, that Stenolaemata constitutes a monophyletic group with Cheilostomata, and that Phylactolaemata have been derived from Ctenostomata could also be rejected. However, the hypothesis that Phylactolaemata and Stenolaemata constitute a monophyletic group could not be rejected. Brachiopoda and Phoronida constitute a monophylum, Brachiozoa. The hypotheses that phoronids are the sister group of articulate or inarticulate brachiopods could be rejected by topology tests, thus confirming the monophyly of Brachiopoda.
