This little-known species is present on the island of New Guinea (Papua New Guinea only) and in northern Australia. On New Guinea, it is known only from a few specimens collected in the south-west Trans-Fly River region. In northern Australia, it has been recorded from a number of coastal sites in Northern Territory (including Melville Island) and Queensland (including Fraser Island) (Gynther and Janetzki 2008). It is suspected to be present in other parts of Queensland (studies underway).
