We received for examination a small colection of ticks captured in the National Park of the Serra da Canastra (MG), between 1979 and 1980. The authors demonstrated the existence of a broad co-accomodation of Amblyomma pseudoconcolor on Endentata of the family Dasypodidae, being Dasypodini the tribe more adjusted to this infestation. In conformity to the Figs 1 and 2, Dasypodini are probably the real hosts of A. pseudoconcolor and also the oldest hosts. For the first time, A. pseudoconcolor is also recorded on Cabassous tatouay, C. unicintus, Priodontes maximus and Euphractus sexcinctus. Also for the first time A. pseudoconcolor and Amblyomma calcaratum were recorded in the State of Minas Gerais. The extoparasites are deposited in the "Departamento de Parasitologia da Universidade Federal de Minas Gerais, Brasil".
