The '''Litostomatea''' are a class of [[ciliates]].<ref name="pmid19120803">{{cite journal  |vauthors=Gao S, Song W, Ma H, etal |title=Phylogeny of six genera of the subclass Haptoria (Ciliophora, Litostomatea) inferred from sequences of the gene coding for small subunit ribosomal RNA |journal=J.

Haptoria includes mostly carnivorous forms such as ''[[Didinium]]'', a species of which preys primarily on the ciliate ''[[Paramecium]]''. Trichostomatia (trichostomes) are mostly [[endosymbiont]]s in the digestive tracts of vertebrates. These include the species ''[[Balantidium]] coli'', which is the only ciliate parasitic in humans. The group Rhynchostomatia includes two free-living orders previously included among the Haptoria, but now known to be genetically distinct from them, the Dileptida and the Tracheliida.<ref>{{cite journal|last=Vďačný|first=Peter|title=Morphological and molecular phylogeny of dileptid and tracheliid ciliates: Resolution at the base of the class Litostomatea (Ciliophora, Rhynchostomatia)|journal=Eur J Protistol |date=November 2011  |pmid=21641780|doi=10.1016/j.ejop.2011.04.006|pmc=3234341|volume=47|issue=4|pages=295–313|display-authors=etal}}</ref><ref>{{Cite journal|last=Gao|first=Feng|last2=Warren|first2=Alan|last3=Zhang|first3=Qianqian|last4=Gong|first4=Jun|last5=Miao|first5=Miao|last6=Sun|first6=Ping|last7=Xu|first7=Dapeng|last8=Huang|first8=Jie|last9=Yi|first9=Zhenzhen|date=2016-04-29|title=The All-Data-Based Evolutionary Hypothesis of Ciliated Protists with a Revised Classification of the Phylum Ciliophora (Eukaryota, Alveolata)|journal=Scientific Reports|language=en|volume=6|page=24874|doi=10.1038/srep24874|issn=2045-2322|pmc=4850378|pmid=27126745|bibcode=2016NatSR...624874G}}</ref>
