It is found only in the Top End Region of the Northern Territory in Australia. TaxonomyThe description of the species was published by Darrell Kitchener in 1989, emerging from a revision of the genus Zyzomys. The holotype was an adult female, collected near Ja Ja Billabong in the Northern Territory, amongst some large boulders at outlying sandstone near a creek. The specific epithet maini was a tribute by the authors upon the retirement of Bert Main from the zoology department of the University of Western Australia. DescriptionThe rat typically grows to a size of {{convert|15|cm|in|0}} in length with a mass of {{convert|100|to|150|g|0}}. It can be distinguished from other local rodents by its long whiskers, swollen tail and Roman nose.[3] It is an entirely terrestrial and nocturnal species, with a diet that consists mainly of seeds, fruit and some other vegetable matter. The rat will cache large seeds or at least move them to sites where it is safe to eat.[4] It is able to breed all year round but females are rarely found to be pregnant late in the dry season.[5] Distribution and habitatEndemic to the sandstone massif of western Arnhem Land, the population is highly fragmented as a result of the topographic complexity of the deeply dissected plateau. The preferred vegetation for the rat is monsoonal rainforest which is found patched throughout the landscape.The total area of occupancy is estimated to be from {{convert|100|to|1000|km2|0}}.[3]ConservationThe species is listed as near threatened with the IUCN, although the population of the species is in decline. Approximately 30% of the population is found within Kakadu National Park.[2] References1. ^{{cite journal |author=Woinarski, J. |author2=Burbidge, A.A. |last-author-amp=yes |title=Zyzomys maini |journal=The IUCN Red List of Threatened Species |volume=2016 |page=e.T23326A22457141 |publisher=IUCN |year=2016 |url=http://www.iucnredlist.org/details/23326/0 |doi=10.2305/IUCN.UK.2016-2.RLTS.T23326A22457141.en |access-date=8 November 2017}} }}2. ^1 {{cite web|url=http://www.iucnredlist.org/details/23326/0|title=Zyzomys maini |work=The IUCN Red List of Threatened Species|year=2008|accessdate=24 December 2015|publisher=International Union for Conservation of Nature and Natural Resources}} 3. ^1 2 {{cite web|url=http://www.environment.gov.au/cgi-bin/sprat/public/publicspecies.pl?taxon_id=25906|title=Zyzomys maini — Arnhem Rock-rat, Arnhem Land Rock-rat, Kodjperr|year=2015|accessdate=24 December 2015|publisher=Department of the Environment|place=Canberra}} 4. ^{{cite web|url=http://www.lrm.nt.gov.au/__data/assets/pdf_file/0019/10837/arnhem_rockrat_vu.pdf |title=Arnhem Rock-Rat - Zyzomys maini |author=John Woinarski |date=1 May 2006 |accessdate=24 December 2015 |publisher=Northern Territory Government |deadurl=yes |archiveurl=https://web.archive.org/web/20160304190602/http://www.lrm.nt.gov.au/__data/assets/pdf_file/0019/10837/arnhem_rockrat_vu.pdf |archivedate=4 March 2016 }} 5. ^{{cite web|url=http://www.dpaw.wa.gov.au/images/documents/plants-animals/threatened-species/recovery_plans/Approved_interim_recovery_plans_/zyz_ped_irp5.pdf|title=Antina (Zyzomys Pedunculatus) - Interim recovery plan|date=April 1996|accessdate=24 December 2015|author=Andrew Burbidge |publisher=Department of Conservation and Land Management}}
