'''''Rankinia''''' is a genus of small agamid reptiles. As currently delineated, it is monotypic, containing only '''''Rankinia diemensis''''' (Gray, 1841),<ref>{{NRDB genus |genus=Rankinia |date=4 August |year=2020}}</ref> also known as the '''mountain heath dragon''' or '''mountain dragon'''. It is endemic to Australia.<ref name=RDB/>

==Distribution and habitat== It occurs in the uplands of New South Wales and Victoria, as well as in Tasmania, where it is the only native agamid. Mountain dragons are found in dry woodlands and heaths with access to open areas for sunning themselves. They are oviparous and feed on ants and other small invertebrates.<ref>{{Cite web |url=http://www.parks.tas.gov.au/wildlife/reptile/Tymdie.html |title=TPWS: Wildlife of Tasmania – Mountain Dragon |access-date=2020-08-04 |archive-date=2008-06-12 |archive-url=https://web.archive.org/web/20080612214123/http://www.parks.tas.gov.au/wildlife/reptile/Tymdie.html }}</ref><ref name=Cogger1979>Cogger, H.G.

They do not climb very high, relying instead on camouflage to evade predators.<ref name="Griffiths"/>

==Description== Their overall colour is grey to reddish brown, with two rows of lighter-coloured paravertebral stripes or blotches running down their backs. These stripes are deeply scalloped, so they appear like two series of blotches. They can have cream-coloured bellies. Individuals can grow up to 20&nbsp;cm in length, although the average length is somewhat smaller, with females typically growing larger than males. The average snout to base of tail length is 7.5 centimeters,<ref>{{cite web |title=Mountain Dragon |url=http://www.arod.com.au/arod/reptilia/Squamata/Agamidae/Rankinia/diemensis |website=Australian Reptile Online Database |access-date=11 April 2020}}</ref> but can be up to 9.<ref name="Museum Victoria Collections">{{cite web |title=Rankinia diemensis (Gray, 1841), Mountain Dragon |url=https://collections.museumsvictoria.com.au/species/8376 |website=Museum Victoria Collections |access-date=11 April 2020}}</ref> They have a row of enlarged spinose (spikey) scales on each side of the tail bases.

The mountain dragon appears similar to the jacky dragon, but can be much redder, and the inside of its mouth is pink (compared to the yellow of the jacky dragon).<ref name="Griffiths">{{cite book|title=Reptiles of the Sydney Region| first=Ken| last=Griffiths| isbn=0-9590203-3-0| publisher=Three Sisters Publications Pty Ltd| year=1987| page=50}}</ref>

They breed in summer, laying 2–9 eggs in a burrow.<ref name="Museum Victoria Collections"/>
