José Paulo Leite Guadanucci, Pedro Ismael da Silva Júnior
Two new species of the genus Tmesiphantes from Serra do Espinhaço, state of Minas Gerais are described. They comprise the first records of the genus outside the Atlantic Forest. Furthermore, the examination of all type material of the genera Tmesiphantes and Melloleitaoina, which have been suggested as sister groups, showed that the thickness of femur III, used to distinguish between them, shows a continuous variation, and the taxonomic usage of this character is discussed.
