Centropyxis gasparella Chardez, Beyens et De Bock, 1988

Diagnosis: Test spherical or very slightly oval in ventral view; in lateral view regularly inflated, slightly compressed at the dorsal anterior part; test with greenish tint, composed of an organic cement embedded with small polymorphous mineral particles. The aboral surface mostly bears some larger grains of sand. Aperture eccentrically located, edges of the aperture form a trapezium, from which originate two broad internal bridges which connect the apertural edges to the dorsal wall; these bridges are perforated by two oval holes.

Dimensions: Length of test: 100-110 µm, width: 95-105 µm, height: 40-44 µm, diameter of the aperture: 26-30 µm.

Ecology: submerged mosses, sediment, Canadian Arctic, Devon Island NWT.
