Epistylis (Rhabdostyla) scyphidiforme Vavrá, 1961 — Stiller, 1971: 67, pl. 35, fig. A

Diagnosis: Size about 60–100 µm long and 25–34 µm wide. Peduncle with 64µm to body length, lower end widens into an adhesive disk. Peduncle may be absent, and the body ends are bounded by an irregular circumferential adhesive, as in Scyphidia . Peristomial collar slightly thickened and slightly wider than the body. Peristomial disc wide, almost flat, slightly sloping, sometimes with small bumps on top. Pellicle is finely striated. The infundibulum is the size of the first third of the body and is positioned diagonally. Contractile vacuole found below the peristomial collar on the right wall of the infundibulum. Cytoplasm fine-grained and filled with refractive food vacuoles and contains long palate-shaped bacteria. Refractive grains accumulate in the middle of the lower ectoplasmic extremities of the body. Macronucleus curved and at the top of the body. Found on the gills of tadpoles of the species Rana esculenta .

Remarks: diagnosis according to Stiller (1971)
