Concatenated sequences of small‐ and large‐subunit rRNA genes were used to infer the phylogeny of 29 species in six genera of T intinnida. We confirmed previous results on the positions of major clusters and the grouping of various genera, including S tenosemella , the paraphyletic T intinnopsis , the newly investigated H elicostomella , and some species of the polyphyletic F avella . Tintinnidium and E utintinnus were found to be monophyletic. This study contributes to tintinnid phylogenetic reconstruction by increasing both the number of species and the range of genetic markers analyzed.
