DiagnosisDiagnosis. Calyptotis thorntonensis differs from its congeners in each of the following characters: a more depressed head and body; external ear represented by a scaly, discoidal depression (scaly, superficial tympanum) instead of either a scaleless tympanum or a scaly conical depression, and generally more longitudinal scale rows at midbody (24 vs modes of 22 or 20).

Comparison with other Calyptotis. Comparisons between C. thorntonensis and C. ruficauda, C. lepidorostrum, C. scutirostrum and C. temporalis have been made on pp. 34, 39,44, and 47, respectively and also in Table 5 (GREER 1983: 48). 
CommentAbundance: only known from the type locality (Meiri et al. 2017).

Morphology: digits: 5, toes: 5 (Singhal et al. 2018, Cogger 2014) 
EtymologyThe name thorntonensis derives from Thornton Peak, the type and, as yet, only known locality for the species.
