[1] The genus Concinnia belongs to the Australian Sphenomorphid clade that contains other genera such as Ctenotus, Anomalopus and the Eulamprus water skinks.

This genus was raised by Skinner et al.(2013) based on molecular phylogenetic analysis of mitochondrial and nuclear DNA sequences, which showed that five sampled species from the Eulamprus tenuis group formed a well supported clade with the then monotypic genera Gnypetoscincus and Nangura.

[2][3] Wells and Wellington (1983) coined the name Concinnia and applied it to the Eulamprus tenuis group delimited by Greer (1989).

Although this tenuis group may form a clade it did not receive strong support in molecular phylogenetic analyses, with C. amplus and C. frerei forming deep lineages of uncertain position relative to C. queenslandiae and C.

[3] There are currently 7 recognized species:[1] Hinulia elegans, described by Gray in 1838, is an unidentified lygosomine that may be Concinnia tenuis.
