|Types||Holotype: NTM R13704, a gravid female, coll. G. Fyfe, 17.ix.1986,|
|Diagnosis||Diagnosis. Distinguished from all other members of the Ctenotus Leonhardii species group by the possession of seven dark dorsal stripes. It may be further distinguished from most similar members of the e. Leonhardii species group, that is those with five dark stripes in their back pattern, by the following characters. In e. septenarius the midlateral stripe is prominent and extends to the face as either a solid line, or as dots and dashes, when anterior to the forelimbs. In contrast, a midlateralline is either completely absent, or only present on the posterior portion of the body, in e. puLchellus, e. hebetior and e. militaris. e. serventyi has a similar lateral pattern to e. septenarius, but is distinguished from this species by the lower number of subdigital lamellae beneath the fourth toe (18-24 compared to 26-32), and usually contacting nasal scales. e. septenarius is also distinguished from other Ctenotus species groups which have a multilined back pattern, by the characteristic red-brown dorsal background colouration [KING et al. 1988].|
|Comment||Synonymy: Ctenotus aphrodite is a synonym of C. septenarius (P. Couper, Glenn Shea, pers. comm., 6 March 2019), but there seems to be no published record of a synonymization, so we retain the two for the time being.|
Limb morphology: 5 digits, 5 toes (Singhal et al. 2018, Cogger 2014)
|Etymology||The species name septenarius is derived from the latin term septenarius which means 'containing seven'. This refers to the seven characteristic black stripes found in the back pattern of this species.|
