(FOISSNER, CZAPIK & WIACKOWSKI, 1981) viewed from the anterior apical aspect.The right paraoral membrane consists of ciliated dikinetids (green line).Four adoral membranelles (blue lines) lie along the left border of the cytostome between the two ends of the C-shaped paraoral membrane. About 15 somatic kineties spiral around the long axis to abut the cytostome anteriorly (pink line). Collected from an ephemeral puddle on the lawn of a public park in Boise, Idaho.September 2006.Stained by the silver carbonate technique (see Foissner, W. Europ. J.
