[2] The specific epithet horni is named by Lucas and Frost for the sponsor of the scientific expedition that provided the type specimen, the pastoralist William Austin Horn.

[4] The snout vent length is recorded up to 34.8 mm, a larger and robust species of the relatively smaller genus of geckos.

The stripes running the length of the body contrasts a darker colour against the mostly tan and pale brown of the scales.

Records of the habitat at the collection sites indicate an association with spinifex mounds, a dominant vegetation type of the arid centre of Australia.

[3] Crenadactylus horni presumed to have become geographically isolated around twenty to thirty million years ago, shown in evidence of ancient genetic divergence, persisting in micro-habitat that has become separated from sister species by the increasingly dry climate of the continent.
