DiagnosisDiagnosis: Ctenotus astictus sp. nov. is distinguished from C. arnhemensis and C. stuarti sp. nov. by having a reduced, simple lateral pattern which lacks any form of pale spots or blotches and by having generally fewerear lobules (mean of 2.9 vs means of 4.8 and 4.1 respectively). Additionally, the relative lengths of the limbs and tail are generally greater in C. astictus sp. nov. than in C. amhemensis and C. stuarti sp. nov. Ctenotus astictus sp. nov. is superficially similar to well patterned specimens of C. vertebralis, but may be distinguished by possessing a grey-brown rather than black upper lateral zone, wider second supraocular scale and fewer ear lobules and supralabial scales [HORNER 1995]. 
CommentLimb morphology: 5 digits, 5 toes (Singhal et al. 2018, Cogger 2014) 
EtymologyThe species name astictus is derived from the Greek term stiktos which means ‘spotted’.It refers to the unspotted nature of the body pattern in comparison to C. arnhemensis and C. stuarti sp. nov. [HORNER 1995].
