Abstract

The family Stratiomyidae presents 2,854 described species worldwide, distributed in 12 subfamilies, one of which is Sarginae. This subfamily is also distributed all over the world, with 530 species in 22 genera-of which 267 species in eight genera are known from Neotropical fauna. The fauna of Sarginae is still poorly known in various parts of the world. There is more over the need of integration in a system of the knowledge on the diversity of the group in the Neotropical region with that of the fauna of the subfamily in other regions-in other words, there is still not a cladistic analysis for the subfamily allowing the insertion of its genera in a global perspective. Merosargus is the Sarginae genus with the highest number of described species-143. However, there is evidence that the genus probably composes a paraphyletic group relative to Acrochaeta. This lack of understanding of the relationship within the Sarginae also refers to the intrageneric relationships. In this case, it is necessary the elucidation of the relationship between Merosargus and genera related, Acrochaeta, Merosargus and Ptecticus. This project proposes a three months stay at the National Museum of Natural History in Washington, United States. Dr. Norman Woodley, presently the most important specialist on Stratiomyidae worldwide, works at this institution. Furthermore, the NMNH collection presents a large amount of material from nearly all Stratiomyidae genera, especially of the Neotropical fauna, and as well a large specimens of species of Merosargus. The visit intends to establish a close collaboration with Dr. Norman Woodley discussing various general issues on the systematics and evolution of the family Stratiomyidae and particularly studying the worldwide diversity of Sarginae, with emphasis on Merosargus. These three months will also include the study of the Stratiomyidae collection. The visit will occur when the student is already working in his MSc in Brazil, after an initial period developing his project. (AU)
