(Müller, 1773) Ehrenberg, 1838

Euplotes Genus: Body ovoid, inflexible; ventral surface flattened, dorsal surface convex; peristome broadly triangular (Kudo, 1966). Cell body is ovoid, dorsoventrally flattened; dorsal surface may be equipped with some ornamentation; three groups of cirri (frontoventral, transverse & caudal); macronucleus C-shaped, "3"-shaped, or horsehoe-shaped (Carey, 1992).
Species: 110 μm long; body is not ornamented (no ridges), peristome large, wide, extending 1/2 of the cell length; AZM narrow; 9 frontoventral, 5 transverse, 4 caudal; macronucleus C-shaped (Carey, 1992). 6 dorsal ridges (How to know the protozoa, 1979). ???
