Contribuição para o conhecimento taxonômico de Trichoptera Kirby 1813 (Insecta) na Reserva Florestal Adolpho Ducke, Manaus, Amazonas, Brasil

Abstract

Trichoptera Kirby, 1813 is the largest order of strictly aquatic insects. It is widely distributed in all biogeographic regions, except for the polar regions. Since it was first reported in Brazil, several studies have been carried out, mainly from the 2000s onwards. However, of all these works, few have proposed to focus on protected areas. The Adolpho Ducke Forest Reserve, for example, is an Environmental Protection Area that is managed by the National Institute for Research in the Amazon, and has grids installed by the PPBio in almost all its total area, but a study on the diversity has never been carried out of Trichoptera exclusively for her. Despite this, based on work prior to this study, a total of 24 species were reported for the Reserve. Therefore, the main objective of this dissertation was to characterize the Trichoptera fauna of the Adolpho Ducke Forest Reserve, Manaus, Amazonas, Brazil. The specimens were collected in the main streams of the Reserve between August 2001 and February 2022, where most of them were preserved in 80% alcohol and stored in the Laboratório de Citotaxonomia e Insetos aquáticos (LACIA). With the results of this work, the Adolpho Ducke Forest Reserve increases to 48 valid species, distributed in 22 genera and 12 families. Of these, it is worth noting Macronema bifidum Flint, 1974 and Chimarra (Chimarrita) forcipata Blahnik, 1997 are reported for the first time for Brazil. 32 new species were also identified for science, where the presence of Mortoniella spp. represents the first record of the genus for the Brazilian Amazon. In addition, a new genus belonging to Polycentropodidae was also discovered. Results reveal how incipient is the taxonomic knowledge of Trichoptera in the reserve and the potential it still must provide novelties to science.
