 A study published in 2017 found no support for separation as a new species of "Pseudantechinus", and the name was proposed to be synonymous with the previously described "Pseudantechinus macdonnellensis".Rory Cooper's false antechinus has been found from the Pilbara into the Great Sandy and Gibson Deserts.It is possible that false antechinuses found on Barrow Island also belong to this species.
