Cattle are the main hosts of Rhipicephalus microplus; however, this ixodid can also parasitize other animal species. We collected a specimen of R. microplus larvae from one bat Molossus rufus (Mammalia, Chiroptera) from the Cachoeirinha municipality (29° 56’ 52’’ S and 51° 5’ 43’’ W), Rio Grande do Sul, Brazil. The specimen was taxonomically identified using identification keys (Vargas 2006). This study reports the first occurrence of this species parasitizing insectivorous bats in Brazil.
