Reliable taxonomic and museum sources consistently use “brown antechinus” for Antechinus stuartii. Some sources also list alternative common names, but that does not change the core fact that “brown antechinus” is a standard and widely used name for this species.

Authoritative taxonomic sources agree that the brown antechinus, Antechinus stuartii, is a mammal in the order Dasyuromorphia and family Dasyuridae. The cited contrary point does not actually contradict the claim; it uses a broader marsupial grouping that is compatible with this classification. No credible evidence in the record disputes the stated order or family.
