Physical Description

Diagnostic Description

Body subspherical, fixed with one side flattened (Fig 1,5,6,10); 46 (35-60) µm long, 44 (35-60) µm wide.; Oral cavity acentric, funnel-shaped; 36 (33-40) EPks and 13 (8-20) IPks; IPk and EPk contiguous, some may be continuous (Fig 1,2,8,9); paroral kinety consists of 20-25 kinetids (not visible in Lugol?s fixed material).; 5 somatic kineties with their cilia directed to the right (when viewed from aboral); K1 slightly dextrally spiralled, K2 describes characteristic arc and has a crook at the end (Fig 1,5,7,10), K5 describes partial circle, originates and ends towards the anterior (Fig 1,7).; One macronucleus, C-shaped, around the oral cavity and below EPZ, opening near the cytostome (Fig 1,2,6,8-10); 1 micronucleus, often indented into the macronucleus, opposite to the cytostome (Fig 1).
