Genus Bothriocroton includes seven species of ticks indigenous to Australia and Papua New Guinea (B oudemansi). Bothriocroton spp resemble Amblyomma spp except they have no eyes. In this group, B aruginans is a parasite of wombats; B concolor and B oudemansi are ectoparasites of echidnas in Australia and Papua New Guinea, respectively. The other four species in this genus parasitize reptiles almost exclusively. B hydrosauri, the blue-tongued lizard tick, is the reservoir of Rickettsia honei on Flinders Island, Australia.
