Nomenclature. Tirjaková (1998) incorrectly ascribed this species to Dujardin (1841) instead of Tucolesco (1962).

Main morphological characters (according to Foissner et al. 1995). Size 30–60 × 10–15 µm in vivo. Body lanceolate with hook-like curved anterior body end and narrowly to broadly rounded posterior body end. Two macronuclear nodules with a single micronucleus in between. Contractile vacuole subterminal. Extrusomes rodlike, about 2–3 µm long, scattered in cytoplasm and attached only to anterior portion of oral bulge. Somatic ciliary pattern Litonotus -like; about 3 right and 2 left kineties.

Distribution. Acineria uncinata was reported from the benthos of the Karlova Ves (Bratislava) Branch of the Danube River (Szentivány & Tirjaková 1994); from activated sludge of sand filters in an indoor school swimming pool in Bratislava (Totková et al. 1994); from a groundwater vein in the Vtáčnik Mountain Range (Krno et al. 1995); from the littoral zone of the Danube River and its through-flowing river arms near the hydroelectric power structures in Gabčíkovo (Matis & Tirjaková 1995); from gravel and debris of the spring area below the Veľký Javorník, Malé Karpaty Mts (Tirjaková 1997a, Tirjaková & Stloukal 2004); from an oligotrophic stream in the National Nature Reserve Rozsutec, Malá Fatra Mts (Tirjaková 1997b); from the benthos of the Hron River and its tributaries (Tirjaková 1998); from the pelagial of the Morava and Danube River (Baláži & Matis 2002a, 2002b); from the benthos of the Gidra River (Tirjaková 2003a); from tree-holes of Quercus dalechampii in Lošonec-lom quarry (Tirjaková & Vďačný 2005); from benthos of the Ulička stream in the Poloniny National Park (Novikmec et al. 2007); from sediment in the littoral zone of the upper Váh River (Tirjaková & Vďačný 2013a); from sediment in the Zubrovica stream, Low Tatra Mts (Tirjaková & Vďačný 2013b).
