Size 50–100 ×10–25 µm in vivo. Body lanceolate with usually broadly rounded posterior body end, left side distinctly vaulted carrying a median rib. Two macronuclear nodules with a single micronucleus in between. Contractile vacuole distinctly subterminal. Extrusomes rod-like and slightly curved, about 5–7 µm long, attached along whole length of oral bulge and to posterior body end. Somatic ciliary pattern  Litonotus-like; 4–7 right and about 4 left kineties.   Distribution.  Litonotus lamellawas found among coastal water plants of a pond in Tomky during August ( Matis 1973); in organic mud from activated sludge plants in Bratislava ( Matis 1988); in agricultural soil near the town of Piešťany ( Tirjaková 1988); in the backwaters of the Danube River in Čičov ( Matis & Tirjaková 1992); in the riverside zone of the Danube River ( Tirjaková 1992a); in a  Sphagnumpond near Rojkov in the Veľká Fatra Mts ( Tirjaková 1992b); in the periphyton and benthos of the Turiec River ( Tirjaková 1993); in the benthos of the Karlova Ves (Bratislava) Branch of the Danube River ( Szentivány & Tirjaková 1994); in the benthos of the Hron River and its tributaries ( Tirjaková 1998); in the benthos from various streams in the High Tatra Mts ( Tirjaková 2001); in the pelagial of the Morava River ( Baláži & Matis 2002a); in the benthos from various localities in the Gidra River ( Tirjaková 2003a); in the benthos from the Stupavský potok brook ( Tirjaková 2003b); in the spring area of the Hron River ( Tirjaková 2006); in the benthos and plankton of a hypertrophic shallow water reservoir near the town of Modra ( Tirjaková 2010); in the sediment from the littoral zone of the upper Váh River near the villages of Bystrá and Stankovany ( Tirjaková & Vďačný 2013a).
