Abstract

Plecoptera (stoneflies) are aquatic insects strongly associated with clean, well-oxygenated freshwater systems, making them valuable indicators of environmental quality. In the Neotropical Realm, the genus Anacroneuria Klapálek, 1909 (Perlidae) is the most diverse, with nearly 380 described species. Here, we studied specimens of Anacroneuria from southern Brazil, describing a new species, Anacroneuria tororo sp. nov., from the states of Paraná and Santa Catarina, and reporting A. iporanga Froehlich, 2002 for the first time in Santa Catarina. Additional distributional records are also provided for A. flintorum Froehlich, 2002, A. petersi Froehlich, 2002, and A. plaumanni Jewett, 1959. Based on literature data and examined specimens, we compile a checklist of 28 Anacroneuria species currently known from southern Brazil. Our findings underscore the importance of continued sampling in this region, where new species are still being discovered and distribution ranges updated.
