Contribuição para o conhecimento taxonômico de Brevitentoria Weaver, 1984 (Trichoptera: Integripalpia) no Cerrado do Distrito Federal, Brasil

Abstract

Brevitentoria is a monophyletic infraorder within Integripalpia, composed of 21 families, of which 10 occur in the Neotropical region and seven in Brazil, including Anomalopsychidae, Atriplectididae, Calamoceratidae, Helicopsychidae, Leptoceridae, Odontoceridae, and Sericostomatidae. The Cerrado, the second-largest biome in Brazil, covering approximately 2,000,000 km2, is a transition region between various biomes, including the Amazon, Atlantic Forest, Pantanal, and Caatinga. Despite this, of the 821 species of Trichoptera recorded in Brazil, only 94 species are found in the Cerrado. The Federal District, with its area entirely covered by the Cerrado, currently encompasses only 16 recorded species, of which only three belong to Brevitentoria: Notalina brasiliana Holzenthal, 1986, Notalina ralphi Silva-Pereira, Oliveira, Desidério, Calor & Hamada, 2022, and Oecetis excisa Ulmer, 1907. The objectives of this study are to investigate the taxonomic diversity of Brevitentoria in the Cerrado of the Federal District, based on adult and immature stage morphology, providing descriptions and illustrations of new species and associated immature stages, as well as recording new distributions for known species. The diversity of Brevitentoria comprises 21 species, distributed among nine genera and four families. Among these, Marilia triangularis Flint, 1983 is recorded for the first time in Brazil. Additionally, nine species have been described and illustrated, currently in the process of publication or already published. The following species are being reported for the first time in the Midwest region and the Cerrado biome: Marilia aiuruoca Dumas & Nessimian, 2009, Phylloicus bidigitatus Prather, 2003, Phylloicus major Müller, 1880, Phylloicus paprockii Prather, 2003. New records are provided for the Midwest region: Barypenthus sp., Grumichella sp., Helicopsyche (Feropsyche) vergelana Ross, 1956, Oecetis carinata Quinteiro & Holzenthal, 2017, Oecetis punctipennis (Ulmer, 1905). And exclusively for the Cerrado: Phylloicus angustior Ulmer, 1905. Therefore, contributions like this are essential for understanding Trichoptera in understudied areas, especially to reduce gaps in knowledge of its fauna in the Brazilian Cerrado.
