Resumen:
Two species of ostracods new to Patagonia, Argentina, are described. One of them, Riocypris whatleyi sp. nov., isdescribed for the first time, and the second, Riocypris sarsi (Daday, 1902) comb. nov., is reallocated from genus Eucypris to genusRiocypris. Inter- and intra-specific variations in shape, size, and sexual dimorphism were evaluated based on geometric morphometricanalysis. Moreover, morphological and morphometric comparative analyses were applied to re-examine living andquaternary specimens recovered from previous studies. Based on these results, a generic reassignment for the PatagonianEucypris fontana (Jurine, 1820) into the genus Riocypris is proposed. Contributing to the knowledge on the systematic andautecology of this enigmatic species, widely distributed in Patagonia and frequently used in paleolimnological reconstructions,generates science-based evidence for their use as indicator species. Additionally, our results emphasize the usefulness ofstudying the living representatives (i.e., with valves and appendages) for elucidating the taxonomic status of the individualspecimens, especially those present in paleontological records and used as bioproxies in paleolimnological studies.
