Infraciliature

Description:

Infraciliature of Coleps hirtus (MÜLLER,1786) NITZCH,1827.The anterior apical cytostome is ringed by an undulating membrane composed of dikinetids (light blue arrowhead).Just posterior to this is a ring of pectinelles composed of two closely spaced dikinetids (yellow arrowhead).The monokinetids of the somatic kineties are located in notches in the cortical plates.Each somatic kinetid (red arrowheads) is associated with a smaller posterior parasomal sac.These parasomal sacs can be easily confused with kinetids in siolver stained specimens. Collected from a freshwater pond near Boise, Idaho.Stained by the silver carbonate technique (see Foissner, W. Europ. J. Protistol., 27:313-330;1991).Brightfield.
