Euplotoides aediculatus ( Pierson, 1943) Borror & Hill, 1995

( Fig. 3 A; Table 3 )

Since its original description by Pierson (1943), it was considered as a junior synonym of E. eurystomus by several authors ( Tuffrau 1960; Wise 1965; Carter 1972). Pierson et al. (1968) recognized this species as valid and contributed to a better separation of E. aediculatus from E. eurystomus . For taxonomic revision and further details, see Foissner et al. (1991).

Euplotoides aediculatus is a freshwater species, but has been reported also from activated sludge plants and brackish water (for review, see Foissner et al. 1991). At the territory of Slovakia, this species was noted for the first time in the main stream of the Danube and in its backwaters near the locality Starý les ( Baláži 2010; unpubl. observ.). Later, E. aediculatus was recorded in the upper Váh river near the villages of Lisková and Bystrá ( Tirjaková & Vďačný 2013a) and in the Zubrovica stream ( Tirjaková &Vďačný 2013b).
