* The Stichotrichia? contains forms with groups of cirri? present on the ventral surface, which they use to crawl along the substrate. They can be distinguished from the similar looking but unrelated Hypotricha? (with which they were once grouped) by the presence of the AZM and by having a contractile or flexible body. Examples include Stylonychia, Oxyticha, Urostyla, Uroleptus, Gonostomum, and Holosticha. |
