Diversidade e distribuição de Odontoceridae (Insecta, Trichoptera) no Brasil

Abstract

The family Odontoceridae (Insecta, Trichoptera) has a great diversity on Neotropical region, with 43 species. Among which, 15 have records in Brazil, with 13 of Marilia Müller, 1880 and the other two of the monotypic genera Anastomoneura Huamantinco e Nessimian, 2004 and Barypenthus Burmeister, 1939. From the species found in Brazil, only three of them are associated with their immature stages, and the majority of the recorded species are from South and Southeast regions. Taxonomic studies can show a hidden diversity in some groups, as well as update geographic data. Thus, this work aims to fill the needing of taxonomic data of Odontoceridae found in Brazil, with emphasis on the association of immatures to future ecological and biomonitoring works, as well as on the distribution of the odontocerid along the Brazilian territory, which may serve as basis to future biogeographical and/or macroecological works. The study was based on material deposited in collections from many research institutes, and additional surveys to the immature rearing. Three genera and 23 species were found, which five of them were new species (Marilia cabocla sp. nov., Marilia callinympha sp. nov., Marilia goiana sp. nov., Marilia hamadae sp. nov. and Marilia mulleri sp. nov.), three new records to Brazil (Marilia alata Flint, 1974, Marilia crea Mosely, 1949 and Marilia salta Flint, 1983) and two known species were associated to the immature stages (Marilia fasciculata Banks, 1913 and Marilia huamantincoae Dumas e Nessimian, 2009). We also present illustrated keys to adults of all species found in Brazil, and to the known larvae in the country.
