Schmid (1984) and Malicky (1993) estimated that the world caddisfly fauna may contain approximately 50,000 species. In this way, only about 20–25% of world species of caddisflies has been described (de Moor & Ivanov 2008). In Brazil, the number of caddisfly species has been increased in the last decades, but studies in some areas are still scarce. The Brazilian Northeast Region comprises 18% of the Brazilian territory, with around 1.6 Tm2, but only 120 species have been recorded, 40 of these in Bahia State. Here, 31 caddisfly species, including Helicopsyche ( F.) catoles n. sp., belonging to 14 genera and eight families were recorded from Chapada Diamantina , Bahia. Two of these previously described species constitute new records for Brazil [ Helicopsyche ( F.) 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 ( Rhyacophylax) coronata , S. ( R.) helenae , S. ( R.) iguazu , S. ( R.) jundiai , S. ( R.) radula , and Marilia major ].
