Diaphanoeca grandis Ellis, 1930. Choanoflagellates with a lorica composed of 12-14 longitudinal costae each formed by 7-8 strips of equal length. Three transverse rings encircle the base of the lorica and one ring, consisting of paired strips, encircles the longitudinal costae towards the anterior end. The protoplast, which is situated centrally within the lorica, bears an anterior collar of tentacles and a single flagellum. Accumulations of detached strips are frequently found at either end of the cell within the lorica. These strips are equal in length to those forming the costae.
