Orders

Armophorea is a class of ciliates in the subphylum Intramacronucleata.[1][2] .[3] It was first resolved in 2004[4] and comprises three orders: Metopida, Clevelandellida,[5] and Armophorida.[6] Previously members of this class were thought to be heterotrichs because of similarities in morphology, most notably a characteristic dense arrangement of cilia surrounding their oral structures.[7] However, the development of genetic tools and subsequent incorporation of DNA sequence information has led to major revisions in the evolutionary relationships of many protists, including ciliates.[8] Metopids, clevelandellids, and armophorids were grouped into this class based on similarities in their small subunit rRNA sequences, making them one of two so-called "riboclasses" of ciliates, however, recent analyses suggest that Armophorida may not be related to the other two orders.[9]
