Tabanidae (diptera) da zona costeira amazônica

Abstract

In recent decades, studies on Amazonian tabanids have been augmented by surveys of tabanofauna in unstudied areas, expansion of collections, description of new species, studies of seasonal age, diurnal activity, attack and arboreal stratification. In the Neotropical region, there are more than 1,800 species described in 65 genera. In the Amazon there are at least 250 tabanid species recorded. Although the colonization process began in the coastal zone, it has been little studied in relation to tabanofauna, so this work aims to organize information on the records of the northern coastal environments, expanding the collections, defining seasonal and local gaps and organizing the classification. Tabofauna records from the entomological collections of the Museu Paraense Emílio Goeldi (MPEG) and the Centro de Estudos Superiores de Caxias, Universidade Estadual do Maranhão, Brazil, were organized and analyzed. A total of 4,811 specimens were studied and organized, belonging to two subfamilies, three tribes, 15 genera and 48 species. Among these, there is one species and one genus probably new, which is being studied and described, which was found in the municipality of Augusto Corrêa, in the state of Pará, with 53 records. The species with the highest number of records is Tabanus kwatta, with 1,462. Five species had their occurrences extended to the Amazon coastal zone. A key for the identification of Tabanidae from the Amazonian coast is being elaborated. The collection of IEPA, Amapá, will still be studied. With this work, the gaps not sampled in the coastal zone are large and are more evident.
