Genus Bothriocroton (formerly Aponomma) 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.
