Tricercomitus (try-sir-ko-mite-us), small cells, drop shaped. The anterior seems to be the narrow end. There is obviously one very long flagellum attached to each cell, but also a rather short one. Usually in clusters. Not uncommon, from the termite Incisitermes. Phase contrast.
Tricercomitus are very small parabasalid flagellates (3-6 µm) with 3 anterior flagella and a recurrent one very long and adhering for most of its length along the body. Tricercomitus divergens is from Kalotermes flavicollis. This scanning EM shows the three anterior flagella and the long adhering recurrent flagellum bearing down-like hairs.
