Abstract
The family Stratiomyidae presents 2,872 described species in 377 genera in the world, distributed in twelve subfamilies. The subfamily Sarginae is one of the most diverse groups, with 562 described species in 22 genera, including 267 species in eight genera known from Neotropical. The family probably originated in the Cretaceous and it is possible that their evolution is related to the evolution of angiosperm rainforests. This fauna was poorly studied and there is not integration between the knowledge of the diversity of the group in the region with the knowledge of the fauna in the world, in other words, there is not a cladistic analysis for the subfamily allowing the insertion of its genera in a global perspective. In addition, there is still not a proposal of the relationships between the genera of the subfamily or between the species of its genera. Adults of sargines have five to six flagellomeres in the antenna and the last flagellomere modified in arista and the presence of vein bm-cu in the wings. Although Sarginae is regarded as a monophyletic group, almost nothing has been proposed on the phylogenetic relationships among its members. The absence of a global treatment of diversity in the subfamily probably requires the maintenance of some paraphyletic genera, as has been indicated for Merosargus related to Acrochaeta, resulting in an inefficient system that allows misleading inferences about evolution and the group and its features. The main goal of this project is to make a cladistic analysis for all genera of Sarginae, with a sample that allows the recognition of paraphyletic genera. This project also intends to make taxonomic revisions of genera with few species, for example, Himantigera and Sagaricera. New material of the stratiomyids collected will be properly preserved to generate a tissue library to obtain DNA sequences of suitable for phylogenetic analysis in the future. (AU)
