Diaphanoeca pedicellata Leadbeater 1972 (also referred to as Campanoeca pedicellata (Leadbeater, 1972) Throndsen, 1974). The subspherical protoplast (4-5 microns long, 4-5 microns wide) bears an anterior ring of 20-30 tentacles. The funnel-shaped lorica chamber is formed by 20-30 longitudinal costae (about 10 microns long) which at the upper end project as spines beyond the anterior transverse costa. The lorica is 45 microns high consisting of one chamber formed by about 14 longitudinal costae and three transverse costae(one towards the anterior end of the lorica, one just below the mid-lorica region, and one towards the posterior end of the lorica chamber). Posteriorly about seven longitudinal costae converge and join with a posterior stalk (about 11 microns long) formed by at least two or three costal strips attached end-to-end. All the costal strips forming the lorica are approximately equal in length and width.
