|Distribution||Australia (New South Wales, Tasmania, Victoria)|
Type locality: Tasmania
|Types||Syntypes: BMNH xxiv.49a-c (possible), Van Diemen's Land (=Tasmania), collector unknown. The name was based by Gray on multiple specimens (number unknown) from Van Diemen's Land obtained by Gray from John Gould. Gray (1845) subsequently used the name Grammatophora angulfer Var. 1 for the taxon he had previously named Grammatophora muricata diemensis. The three specimens xxiv.49a-c are the only spirit preserved specimens in the BMNH listed by Gray (1845) from the type locality without collectors other than those that would preclude them from being Gould specimens available in 1841. There would appear to be no way of either excluding them from the type series of diemensis, or definitively identifying them as syntypes.|
Syntypes: BMNH 19188.8.131.52-30, BMNH 19184.108.40.206-66, BMNH xxiv. 49. f, from Tasmania [Grammatophora angulifera]
Syntypes: BMNH 1946. 9. 4. 33-34, from "towards the Tropic of Capricorn, South Africa", in error [Agama caelaticeps]
|Diagnosis||Diagnosis (genus): Small, short-legged, short-tailed agamid; dorsals markedly heterogeneous (small scales intermixed with much larger spinose scales); enlarged spinose scales arranged in paravertebral, dorsolateral and lateral rows; another prominent row of spinose scales extends along each side of the tail-base; tympanum exposed (J. Melville, pers. comm., 8 Sep 2021).|
Rankinia diemensis is not closely related to R. adelaidensis which clearly is related to Ctenophorus (Hugall et al. 2008).
Type species: Grammatophora muricata diemensis GRAY 1841is the type species of the genus Rankinia WELLS & WELLINGTON 1984: 82.
|Etymology||The genus is named after Australian herpetologist Peter Rankin who died in January 1979 while he tried to catch geckos with ross Sadlier in New Caledonia.|
