Aeglidae is the only freshwater family in the infraorder Anomura. Aegla uruguayana Schmitt, 1942 is one of themost widely distributed species in southern South America and is found in different environments, which makes it an interesting object for population genetic studies. The main objective of this work was to analyse the genetic population structure of A. uruguayana along a sea distance gradient for four populations that were studied in the La Plata Basin with an 1100-km range in relation to an east-west transect. The populations studied were the Río Tercero Reservoir, the Setúbal Lagoon, the Doll Stream and the Urquiza Stream. Aeglid DNA was extracted using a commercial kit that was amplified with ISSR markers. Of the 10 primers tested, we selected four that showed the best resolution and reproducible results. Our studies revealed a He of 0.3479 ± 0.1383 (mean ± SD) and a global FST of 0.3583 (p
