Resumo: | Water beetles possess a wide variety of ecological attributes that allow them to occupy a wide range of aquatic habitats. Temporary ponds are environments that experience recurrent drought periods that may differ in duration; each pond is further characterized by a particular fauna, and by the size of the population that can be supported. The richness (S) and diversity (H') of water beetles collected in temporary ponds in Corrientes province were analyzed. Rarefaction was used to avoid estimation bias and to use comparative methodology. Pearson correlations were calculated using water temperature, depth, surface (m²), diversity (Shannon &amp;amp; Wiener) and richness. A total of 660 individuals, including 42 species, 22 genera and 7 families were recorded. The greatest percentage of species belonged to the family Hydrophilidae (45%) followed by Dytiscidae (32%) and Noteridae (15%), while the remaining families represent less than 10% of the total species. The Kruskal-Wallis tests did not find signifcant differences in diversity and richness between the temporary ponds analyzed. The most correlated variables in different ponds were diversity and hydroperiod, surface and depth.
