Resumen:
A new species of Hydrops is described. The new species has a disjunct distribution with regard
to other species in the genus, occupying subtropical to temperate areas of Parana´ and Plata River basins
(between 198 and 288 309 S), from Pantanal in Mato Grosso do Sul, Brazil, through Paraguay and Parana´
Rivers, with records in the Esteros de Ibera´ , Argentina. It differs from all congeners in the number of total
ventral scales (ventrals plus subcaudals), number of dorsal scales and color pattern. Based on our data and
those of previous authors, we present the variation in lepidosis and measurements, description of the
hemipenes, and known distribution for the new species. Furthermore, a key for the identification of all taxa of
the genus is presented.
