Cyclopyxis kahli var. obliqua Decloitre, 1978
Diagnosis: Test with all the characteristics of the type species described by Deflandre, except one. In the type, in profile view, the plane of the pseudostome and that of the ventral face are parallel. In the variety, the plane of the pseudostome makes a pronounced angle (25 to 30°) with that of the ventral face. The variety can only be recognized in profile view, and it is likely that it has already been seen without being recognized.
Dimensions: Diameter 75 μm; height, 50 μm; pseudostome diameter, 25 μm; buccal depth, 15 and 25 μm.
