Diagnosis 
CommentSynonymy after COGGER 1983.

Tiliqua australis Gray, 1838 and Lygosoma australis Gray, 1839, were both placed in the genus Lygosoma by Boulenger (1887), who erroneously treated Tiliqua australis as the junior secondary homonym. While it can be argued that Lygosoma australis has never been formally rejected as a junior homonym and therefore is available and has priority over Hinulia gracilipes Steindachner, 1870, under Article 59 of the International Code of Zoological Nomenclature we have arbitrarily treated Lygosoma australis Gray, 1839 as a junior secondary homonym of Tiliqua australis Gray, 1838, rejected prior to 1961 (see Loveridge 1934) [fide COGGER 1983: 184].

Limb morphology: 5 digits, 5 toes (Singhal et al. 2018, Brandley et al 2008) 
EtymologyPresumably named after the Latin gracilis (slender) plus pes (foot), referring to the slender, long-toed feet of this elongate skink. (G. Shea, pers. comm., 9 Feb 2024)
