Taxonomy

The genus name Sminthopsis was published by Oldfield Thomas in 1887, the author noting that the name Podabrus that had previously been used to describe the species was preoccupied as a genus of beetles.[1] The type species is Phascogale crassicaudata, published by John Gould in 1844.

The genus is referred to by their common name of dunnarts.
