摘要: There are only 33 records of rodents the subfamily Caviinae Fischer de Waldheim, 1817 (Hystricognathi: Caviidae) infested by hard ticks in South America, where is established. formed three genera: Cavia Pallas, 1766, Galea Meyen, 1833 and Microcavia Gervais Ameghino, 1880. Records Amblyomma pictum Neumann, 1906, A. dissimile Koch, 1844 pseudoparvum Guglielmone, Keirans Mangold, 1990 considered doubtful. Bona fide all for localities south Amazonian basin Argentina, Bolivia, Uruguay Brazil. Thirteen tigrinum 1844, four triste parvum Aragao, 1908 (larvae nymphs these species), one cajennense (Fabricius, 1787) (nymph), Ixodes longiscutatus Boero, 1944 (females, larvae) record I. loricatus 1899 (female). Rodents vital life cycle probably longiscutatus. It hypothesized that Ixodidae precedes establishment America (Neotropical), therefore this host-relationship relatively recent measured evolutionary times starting late Miocene or afterwards. appears to be relevant speciation as shown studies carried out Argentina Uruguay. This role has been hidden presumably because type hosts was ignored most ecological tick performed America.
