Rhipicephalus australis Fuller, 1899 Originally described from cattle in Australia, R. australis was been considered a junior synonym of R. (Boophilus) microplus (e.g., Neumann 1901; Uilenberg 1962; Roberts 1970); however, the addition of genetic evidence suggesting the possibility that different species were included under the rubric R. microplus (Labruna et al. 2009) led to a detailed investigation, and Estrada-Peña et al. (2012) reinstated R. australis as a valid species. In continental Southeast Asia R. australis has been recorded from Cambodia (Estrada-Peña et al. 2012). It is also present in Australia, Indonesia, the Philippines, New Guinea and New Caledonia (Estrada-Peña et al. 2012), suggesting that it may be more common in continental Southeast Asia than is currently recognized. The female, male and larva are described in Estrada-Peña et al. (2012).
