Abstract

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].
