(7) Eucypris virens (Jurine, 1820),

Eucypris obtusa Fuhrmann & Goth, 2011 and Eucypris helocrenica Fuhrmann & Goth, 2011

Eucypris virens is known to be highly variable in carapace shape (G.W. Müller 1900; Tétart 1985; Meisch 2000) and to consist of a complex of at least 40 and potentially as many as 60 or more so-called cryptic, morphologically unrecognizable ‘genetic species’ (Bode et al. 2010; Koenders et al. 2012). For that reason and awaiting further morphological and genetical studies, the following two species, which differ from E. virens only in small differences in the shape of the carapace and valves, are placed in the list of synonyms of E. virens: Eucypris obtusa Fuhrmann & Goth, 2011 (syn.: Eucypris virens var. obtusa G.W. Müller, 1900) and E. helocrenica Fuhrmann & Goth, 2011 .
