Centropyxis declivistoma, after Chardez, 1990

Centropyxis declivistoma Chardez, 1990

Diagnosis: Test ovoid, slightly compressed dorso-ventrally, especially in the anterior region, embedded with polymorph mineral platelets. Pseudostome oval, formed by a short visor which covers a small but very elongated and straight aperture. In lateral view, this pseudostome forms an angle of some degrees with the longitudinal axis. In apertural view, this aperture is a simple slit. One long lobopodium observed.

Dimensions: Length 150-154 µm; width 98-100 µm; thickness 70-76 µm; pseudostome 19-20 x 6.5-9.9 µm.

Ecology: Freshwater. Tirol, Austria, Germany.
