RESUMO
ABSTRACT Prof. Dr. Claudio Gilberto Froehlich's career is presented here using numbers and actions guided by a genuine way to study biodiversity, especially aquatic ecosystems. An extensive number of publications is accompanied by an investment in human resources training and establishing a vast network of collaborators and friendships. Dr. Peter Zwick mentioned the Southeast Region of Brazil as "Froehlich's Autonomous Stonefly Republic", to express the magnitude of Prof. Froehlich's scientific production on Neotropical Plecoptera. In this special volume in honor of Prof. Froehlich, the numbers of his career support Zwick's affirmation. Thirty-nine students graduated in MSc and/or PhD courses, two books, and 20 book chapters were published, as well as 95 articles on geoplanids, onychophorans, cnidarians, mayflies, coleopterans, caddisflies, and especially stoneflies. Froehlich's legacy includes different ways to observe nature, from taxonomy to ecology, from flatworms to stoneflies.
RESUMO
A new species of Helicopsyche subgenus Feropsyche from Chapada Diamantina is diagnosed, described, and illustrated. Helicopsyche catoles n. sp. is easily distinguished from congeners by the following features: inferior appendages clavate, each bearing a posteroventral projection with 2-4 setae in lateral view, and tergum X with a notched apex and a short setal row along its length in dorsal view. Additionally, new records from Chapada Diamantina, Bahia, Brazil, are presented. A total of 31 species, including the new species, are recorded, belonging to 14 genera and 8 families. Two of these species constitute new records to Brazil (Helicopsyche (Feropsyche) succincta and Marilia misionensis) and another 10 of these species represent new records for Bahia [Chimarra (Curgia) hyoeides, Macronema hageni, M. partitum, Polyplectropus tragularius, Smicridea coronata, S. helenae, S. iguazu, S. jundiai, S. radula and Marilia major].
