During a survey of ticks on horses in November 2000, at the University of São Paulo farm in Pirassununga county, São Paulo, Brazil, 1 gynandromorph of Amblyomma cajennense was collected from a naturally infested horse. In another survey on dogs in March 2001, in the urban area of Monte Negro, Rondônia, Brazil, a gynandromorph of Rhipicephalus sanguineus was collected from a naturally infested dog.
