The description of Anacroneuria suerre sp. nov. from Costa Rica (Plecoptera: Perlidae) and using nymphs in ecotoxicological studies

: The lack of nymph-adult associations limits our knowledge of the ecology, history and sensitivity of aquatic insects. In this study, the new species, Anacroneuria suerre sp. nov is described from Costa Rica based on the male, female, and nymphal stages. We briefly discuss the use of Plecoptera in ecotoxicological studies.
