New records. TURKEY: Erzurum Province, Teke stream, 23.7.2006, 39°51'50''N; 41°13'26''E, 2000 m. a.s.l., on Protzia sp. (Hydrachnidia, Hydryphantidae ); Konya Province, Akşehir, Yayla Stream, 18.4.2004, 38°19'07''N; 31°27'21''E, 1060 m. a.s.l., on Protzia sp.; IRAN: Shanderman (Chafrood) stream 15 km from Masal city, 37°29'N; 49°06'E, 20.7.2006, on Torrenticola barsica (Hydrachnidia, Torrenticolidae ).

Diagnosis. Suctorian ciliate with flattened, disc-shaped or elongate cell. Macronucleus ovoid, centrally located. Contractile clavate tentacles evenly distributed over all the edge of the cell, in some cases only at apical part. Stalk cup-shaped or elongate with different lengths, uniformly expanding upwards, with transversal folds. There are from one to three contractile vacuoles in apical part of the cell.

Measurements: Cell length 25–180 μm, width 15–160 μm, length of stalk 17–192 μm.

Remarks. New for Turkey and Iran.
