Description :

Bicosoeca tenuis Kent, 1880. Bicosoeca cells with a lorica that is elongate-ovate or subfusiforme, nearly three times as long as broad, tapering equally at each extremity, pedicel scarcely one-half the height of the lorica, protoplast with a lip-like projection, slightly exsert anteriorly. Length of lorica 8.5 to 10.2 microns The assignment of this species to Bicosoeca is incorrect, because in Bicosoeca, one flagellum attaches the cell to the lower end of the lorica, whereas here both flagella project from the opening of the lorica.
