Notes
The structural organization of the dorsal cell surface was studied in parallel with the pattern of the dorsal argyrome in Euplotes bisulcatus and other related species of Euplotes. Evidence is provided for the involvement of cortical alveoli of similar width in the construction of double argyromes. Argyromes usually described as double-patella are shown to result from the presence of longitudinal ridges of varying shapes on the dorsal cell surface, which strongly affect the appearance of the argyrome under light microscopy. On a completely different experimental basis, this work supports the suggestion by Gates and Curds that the typology of the dorsal argyrome of Euplotes should be restricted only to the basic types single, double, and multiple. In addition, it reiterates the diagnostic value of cortical sculpturing in Euplotes taxonomy.
