Dorsal silverline system

Image of Lembadionidae

Description:

Dorsal silverline system (argyrome) of the oligohymenophorean ciliate, Lembadion lucens (Maskell, 1887) Kahl, 1931. There are 25-35 evenly spaced longitudinal somatic kineties. The posterior 2/3 of the pellicle of L. lucens has an areolate pattern divided into small roughly rectangular depressions (similar to the pattern of the entire pellicle of L. bullinum). The dikinetids of the somatic kineties occupy the center of the rectangles. The anterior 1/3 of the pellicle has a longitudinal striate pattern (similar to the pattern of the entire pellicle of L. magnum). The somatic dikinetids lie in the center of these striae. This specimen is stained by the silver carbonate technic (see Foissner, W. Europ. J. Protistol., 27:313-330;1991). This technic usually demonstrates the infraciliature which includes kinetodesmal fibrils and other structures not considered part of the silverline system but in this instance the silveline system and somatic dikinetids are stained. L.lucens is distinguished from L. magnum and L. bullinum by its smaller size and the structure of its pellicle. Specimen collected from a freshwater pond near Boise, Idaho 2005.Brightfield.
