Euplotes moebiusi Kahl, 1932

( Figs 2 View FIGURE 2 A–G; Table 3 View TABLE 3 )

This species was described from salt water ( Kahl 1932). Later it was recorded also from activated sludge and freshwaters where prefers polysaprobic or beta- to alfa-mesosaprobic levels (for review, see Foissner et al. 1991).

In Slovakia, E. moebiusi was found at several localities: in the River Danube near Sporná Sihoť ( Matis & Tirjaková 1995; unpubl. observ.); in the Morava river ( Baláži & Matis 1999, 2002; Baláži 2010); in streams of SE Slovakia during years 2011–2012 (unpubl. observ.); and in the sediments of the Váh river near the village of Lisková ( Tirjaková & Vďačný 2013a).
