Two macronuclear nodules with a single micronucleus in between. Contractile vacuole distinctly subterminal. Extrusomes rod-like, about 3–5 µm long, attached along whole length of oral bulge. Somatic ciliary pattern Litonotus -like; 10–12 right and about 5 left kineties.

Litonotus anguilla was recorded in submerged and wet mosses from Slovenský Raj at a frequency of about 1.9 and 1.5, respectively ( Tirjaková & Matis 1987); in the backwaters of the Danube River in Čičov ( Matis & Tirjaková 1992); in the periphyton and benthos of the Turiec River ( Tirjaková 1993); in the Stupavský potok brook ( Matis & Tirjaková 1994); in a groundwater vein in the Vtáčnik Mountain Range ( Krno et al. 1995).
