Abstract

The tarantulas of the subfamily Theraphosinae comprise the most diverse group of Mygalomorphae, a lineage that also includes sheet-web spiders and trapdoor spiders.Theraphosinae, endemic to the New World, are composed of large spiders bearing abdominal urticating setae used for defense. The morphology of these setae, as well as the traditional morphological characters, have been used to infer phylogenies, resulting in the division of genera into different groups. One of these groups, namely Grammostolini is formed by genera with type III and IV urticating setae, while the group namely Hapalopini, it is formed by genera with only type III urticating setae. They are distributed throughout the Americas and their evolutionary histories present different situations, depending on theuse of morphological or molecular data. Using a phylogenomics of Ultraconserved Elements, the objective of this project is to test the monophyly of tarantulas from these two groups, and to understand the evolution of their morphological characters, investigate the diversification of these lineages and reconstruct the ancestral areas of their representatives. The samples to be used for phylogenomic analyzes will be accessed through field collecting and zoological collections from South America and Mexico. This studywill provide a comprehensive overview of the evolution, diversification and biogeography of Grammostolini and Hapalopini tarantulas, using innovative methods, which can be useful as a model for studies biogeographic and evolutionary involving other groups of organisms with uniform morphology and discordant evolutionary topologies.
