RESUMO:

Trichoptera Kirby comprises the order of strictly aquatic insects with the largest number of species, since so far about 15.000 species have been described, but it is estimated that there may be about 50.000 species. The order has representatives on all continents except Antarctica. In the Neotropical Region, 3.262 species were described, of which 738 occur in Brazil, representing 16 families and 70 genera. When it comes to the Brazilian regions, the northeast has received little attention from taxonomists, which eventually reflected on the knowledge of the Trichopterofauna in this region. In this context, studies of faunal survey and description of new species in the Northeast Region are important. The study area is the Parque Municipal de Mucugê, located in Chapada Diamantina. The PMM shelter the source of three streams (Bandeira, Boiadeiro and Morro Fervido), in addition to the Cumbuca and Mucugê rivers on its banks, all part of the Paraguaçu basin. Thus, it is also an area of relevance for the preservation of the region's water resources. Six points were established within the PMM (Bandeira Stream, Boiadeiro Stream, Morro Fervido Stream, Tiburtino Waterfall, Cumbuca River and Piabinha River) and five points in the vicinity of the PMM. 5637 specimens were collected using light attraction traps (UV light pan trap, light sheet and Pensilvânia), flight intercept trap (malaise) and puçá. The specimens were diaphanized using potassium hydroxide (KOH) or lactic acid for identification and the new species were illustrated with the microscope equipped with a drawing tube and vectorized in Adobe® Ilustrator® CS5. With respect to identified species eight from them constitute new records for Bahia (Cernotina antonina, C. bibrachiata, C. filiformes, C. flexuosa, Helicopsyche (Feropsyche) monda, Marilia aiuruoca, Phylloicus major and Triplectides neotropicus) and six already have records from Bahia, but are new records for the Chapada Diamantina region (Phylloicus paprockii, Atopsyche (Atopsaura) kamakan, Oecetis froehlich, Oecetis furcata, Triplectides gracilis and Chimarra (Chimarra) anticheira). In addition, eight new registrations for the Caatinga biome (Phylloicus major, Helicopsyche (Feropsyche) monda, Triplectides neotropicus, Marilia aiuruoca, Cernotina antonina, C. bibrachiatta, C. filiformes and C. flexuosa). This work, the number of records for the Northeast region becomes 141 species and Bahia from 72 to 80 species registered. This shows that the Northeast Region has a considerable variety and that the numbers have not reflected the diversity of order in the region. Therefore, taxonomic studies are of great importance for the knowledge about the species occurring in the region, as well as the distribution.
