DiagnosisDiagnosis: Morphologically shares the external features of G. variegata (see above) but distinguished from that species by karyotype (2n=40a or 2n=38a) (Fig. 2C–D). As with G. variegata, G. versicolor is most similar G. montium but distinguished by grey to brown rather than more rufous dorsal colouring, with white markings that form a posterior highlight or margin on the trailing edge of the dark dorsal lines, rather than forming discrete circular dots that are not coordinated with the dark markings. This diagnosis applies to populations of Gehyra genetically assignable to “Clade 5” of Sistrom et al. (2013). From Hutchinson et al. 2014. 
CommentThis species includes all of the eastern Australian populations formerly assigned to G. variegata.

Distribution: see map in Kealley et al. 2018: 4 (Fig. 1).

Karyotype: 2n=40a and 2n=38 
EtymologyThe specific name chosen here is from the Latin meaning ‘variable in colour’, appropriate for a species that shows considerable individual and geographic variation. Given the very wide distribution of the species it is somewhat surprising that no older name appears to be available for it in the synonymy of G. variegata. Cogger et al. (1983) listed several synonyms of Gehyra variegata. Subsequently, these have proven to be based on specimens attributable to other Australian Gehyra species groups, especially eastern species related to G. australis (Bauer & Henle 1994; Shea 1995). Other possible synonyms were discussed by Sistrom et al. (2009) in reference to G. lazelli; none apply to G. versicolor (HUTCHINSON et al. 2014)
