Ornithodoros capensis sensu lato (s. l.) is a worldwide-distributed group of soft ticks that parasitize birds in insular and continental lands. It is currently composed of 11 morphologically closely related species. Several viral and bacterial pathogens, and particularly Coxiella-like endosymbiont organisms have been described coexisting with ticks of this group. Since it last report in 1983, the presence of O. capensis s. l. in Brazil has remained undocumented. By a morphological analysis of larvae and a molecular characterization of ticks and Coxiella genes we describe for the first time O. capensis sensu stricto in Brazil from specimens collected on Queimada Grande Island, in São Paulo state.
