Estudo Taxonômico das espécies sul-americanas de Stenomicra Coquillett, 1900 (Diptera: Periscelididae)

Abstract

Stenomicra Coquillett has a wide worldwide distribution, except in Antarctica, however, understudiedin the New World where, to date, were known seven extant species and two fossils. Different authors have already suggested that the diversity of Stenomicra in the Neotropical Region is underestimated and that probably more than 100 species are yet to be described. Thus, this dissertation aimed to contribute to increasing knowledge about the diversity of Stenomicra Coquillett species in the Neotropical Region, with a focus on South America. To this end, taxonomic and morphological studies were carried out on specimens from Brazil, the North and Northeast regions, and Peru. This dissertation was organized into two chapters, the first deals with the description of new species from the North and Northeast of Brazil and an key illustrated identification for neotropical species; the second deals with the description of new species from Peru and the first records and species of the subgenus Podocera for South America. Were obtained seven new species of Stenomicra (Stenomicra): S. dorsimaculata sp. nov., S. geovaniae sp. nov., S. limeirai sp. nov., S. longiseta sp. nov., S. paraensis sp. nov., S. frontalis sp. nov. and S. rafaeli sp. nov.; and a one specie from the subgenus Podocera: S. (Podocera) cuzcana sp. nov. A dichotomous and illustrated key was created for 12 species of Stenomicra; in addition to distribution maps for all species described here.
