(15) Riocypris Klie, 1935 :

Riocypris was erected for the single species R. uruguayensis Klie, 1935 , described from Uruguay. The genus remained monospecific until Karanovic (2008) described R. hinzeae from Australia, additionally transferring the following two species to Riocypris : R. fitzroyi ( McKenzie, 1966) , formerly assigned to Candonocypris , and R. fontana (Graf, 1931) , previously allocated to Eucypris . More recently, Díaz & Martens (2014) transferred E. fontana into the newly erected genus Argentocypris Díaz & Martens, 2014 . For reasons of both the differences in the structure of the carapace and biogeographic occurrence, the latter authors (op. cit.) expressed their doubts whether the West Australian R. hinzeae and the South American R. uruguayensis would be congeneric. We follow Díaz & Martens (2014) and only provisionally keep R. hinzeae in the genus Riocypris . As for R. fitzroyi , it is here reallocated to Candonocypris .
