8. Rhipicephalus australis Fuller, 1899 .

Australasian: 1) Australia, 2) Indonesia (east of Wallace’s Line), 3) New Caledonia, 4) Papua New Guinea, 5) Solomon Islands; Oriental: 1) Cambodia, 2) Indonesia (west of Wallace’s Line), 3) Malaysia, 4) Philippines; remote islands: 1) Pacific Ocean Island (central) of Tahiti (Estrada-Peña et al. 2012, Petney et al. 2019).

Rhipicephalus australis was widely confused with Rhipicephalus microplus prior to its reinstatement by Estrada-Peña et al. (2012).

Barré & Uilenberg (2010) stated that Rhipicephalus microplus was introduced into the Solomon Islands with cattle imported from Australia, but the tick actually involved is here thought to be Rhipicephalus australis . The geographic distribution of Rhipicephalus australis is probably broader than currently recognized, since distributional data are limited, and our understanding of the range of this species is based on Estrada-Peña et al. (2012) and Petney et al. (2019).
