Portrait of Bicosoeca petiolata, a colorless loricate flagellate (synonymous with Poteriodendron petiolatum). This species is colonial with daughter cells forming stalks attached to the mother lorica after division. Most species of this genus are solitary. The cells of this colony are retracted with the long hair bearing flagellum tightly coiled on the anterior end of the cell (seen well in the cell on your left in this image). The second short smooth flagellum is directed posteriorly attaching the cell to its lorica. The lorica is organic. From fresh water marsh with Typha (Cattail) near Boise, Idaho. Differential interference contrast.

Bicosoeca epiphytica Hilliard, 1971. Bicosoeca cells with a body 3.5-6.5 x 2.5-4.5 microns long, lorica 8-10x3.5-5 microns The lorica of this species has an undulating surface. The lorica has about 8-10 ridges and is rounded at the posterior. It tapers slightly at the anterior, before a flared aperture. The lorica has a short pedicel, which is 0.5-1 times the lorica length, and terminates with a distal button as is characteristic in this genus.

Bicosoeca vacillans Stole, 1888. Bicosoeca cells located in a stalked lorica, the chamber of which measured 17-25 microns long. The lorica chamber was approximately cylindrical with a slightly pointed posterior and a pedicel of 1-1.5 times the lorica length. Loricas may differ slightly in shape. The lorica wall was most frequently curved slightly outwards at the aperture to a greater or lesser extent and in some cases the lorica was waisted below the aperture. The lorica had fine horizontal bands spaced about 0.4 microns apart, with numerous fine perpendicular fibres in each band. Cells were sub-spherical and had a flattened indistinct peristome. The anterior flagellum was about 3 times the cell length and held at an angle to the longitudinal axis of the cell. The posterior flagellum was attached to the base of the lorica via a fine thread.
