Evolutionary relationships of taxa within the ciliate subclass Haptoria are poorly understood. In this study, we broaden the taxon sampling by adding 14 small subunit ribosomal RNA gene sequences, 13 large subunit ribosomal RNA gene sequences and 13 ITS1-5.8S-ITS2 gene sequences of haptorians. This includes the first molecular data from two genera, Pseudotrachelocerca Song, 1990, and Foissnerides Song & Wilbert, 1989. Phylogenies inferred from the three individual genes and concatenated data sets show that: (i) the subclass Haptoria could be a multiphyletic complex with about up to four main clades while interrupted by some intermingled with the related subclasses Rhynchostomatia, Trichostomatia and some incertae sedis; (ii) the genus Pseudotrachelocerca Song, 1990, is clearly separated from Litostomatea and clusters within an assemblage comprising the classes Prostomatea, Colpodea and Plagiopylea; (iii) both morphological evidence and molecular evidence indicate that the genus Foissnerides should be transferred from family Trachelophyllidae to Pseudoholophryidae; (iv) the validity of the order Helicoprorodontida Grain, 1994, and its monophyly is strongly supported; (5) the family Chaeneidae does not belong to the order Lacrymarida but represents a distinct clade in the subclass Haptoria.
