During two field trips in the state of São Paulo, two of us became infested by two adults, three nymphs, and one larva of the capybara tick, Amblyomma dubitatum Neumann, 1899 (= Amblyomma cooperi Nuttall and Warbuton, 1908). Previously, there has been only a single report of an A. dubitatum adult tick from humans. Our observations on human infestation by all parasitic stages of A. dubitatum suggest that this behavior may be more frequent than previously thought, especially in the case of immatures, which are herein reported from humans for the first time.
