Cyclopyxis eurystoma alta
C. eurystoma f. alta, after Jung, 1942

Cyclopyxis eurystoma f. alta  Jung, 1942

Diagnosis:  Test and coverage as the type. However, the side profile is not as regular and the height is more significant. Ecologically, there is little difference between the type and the variety, although the latter seems to tolerate more significant moisture variations than C. eurystoma due to its occurrence. A certain resemblance to Centropyxis minuta must be pointed out, but the pseudostome of C. eurystoma f. alta is centrally stored, which makes it a true Cyclopyxis.

Dimensions: Height 45-47 um; diameter 37-40 um, aperture 13-16 um.

Ecology: Freshwater, Chile, South America
