[2] An early osteological comparison to related taxa presented considerable and unusual variation, such as being clawless, but in particular the forked arrangement of phalangeal bones within the digits of the gecko.

[1] A genus, sometimes assigned to the Diplodactylidae family, whose tiny and superficially similar species have diverged in isolation at a range of habitats across a wide geographic area.

A molecular analysis of northern populations in 2012 examined the reported ancient divergence and up to ten lineages in northwestern Crenadactylus, with indication of geographical ranges restricted to less than 100 km2.

Prior to the reclassification of the Crenadactylus species, the population was recognised as occurring in a large distribution range that covered most of the western and central regions of Australia.

The various species are found in habitat that includes the leaf-layer at the floor of woodlands, underneath rocks, in hummocks of Trioda vegetation in spinifex country, under logs and other dead woody litter, and beneath the rubbish piles introduced to their environment by human activity.
