Grammatophora muricata diemensis Gray, 1841 Rankinia is a genus of small agamid reptiles.

[3] 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.

[6] Their overall colour is grey to reddish brown, with two rows of lighter-coloured paravertebral stripes or blotches running down their backs.

[8] They have a row of enlarged spinose (spikey) scales on each side of the tail bases.
