The species Amblyomma longirostre Koch, 1844 is poorly known in the state of Rio Grande do Sul. Usually the adult stage could be found on Sphigurus spp. and the immatures on birds (Passeriformes). Although A. longirostre is distributed in the Neotropical region, from Panama to Uruguay, it also occurs in Central America and the United States. The aim of this study was to report that Ramphastos dicolorus Linnaeus 1766 is a new host record for this tick species.
