Theplagiopylidsare a small order ofciliates,including a few forms common in anaerobic habitats.
The body cilia are dense, and arise frommonokinetidswith an entirely unique ultrastructure; one or two rows ofdikinetidsrun into the oral cavity, which takes the form of a groove, with a deep tube lined by oral cilia leading to the mouth. The order was introduced by Eugen Small and Denis Lynn in 1985, who treated it as a subclass ofOligohymenophorea.Since then they tend to be treated as an independent class, possibly affiliated with theColpodea.Class Plagiopylea is divided into two clades:[2]one contains members of the order Plagiopylida (likePlagiopyla frontataandTrimyema compressum) and the second clade contains plagiopyleanciliateassociated withdenitrifyingobligateendosymbiontCandidatusAzoamicus ciliaticola.[3]
