Baker, Andrew M, Mutton, Thomas Y & Hines, Harry B, 2013, A new dasyurid marsupial from Kroombit Tops, south-east Queensland, Australia: the Silver-headed Antechinus, Antechinus argentus sp. nov. (Marsupialia: Dasyuridae), Zootaxa 3746 (2), pp. 201-239 : 217

(3) A. argentus versus A. flavipes leucogaster Gray

Pelage: A. argentus has pale olive-buff fur on the upper hind feet and tail base, whereas A. flavipes leucogaster has marked yellowish-brown fur on the hands, feet and tail base. A. argentus has deep olive-buff fur on the flanks and rump, whereas A. flavipes flavipes has brownish-yellow-orange fur on the rump and flanks.

External measurements: A. argentus has similar external body measures to A. flavipes leucogaster (Table 4).

Dentary: Antechinus argentus differs from A. flavipes leucogaster in absolute measurement for one dentary character in both males and females: smaller IPV. A. argentus has one other dentary feature in females that differs significantly (p<0.05) from A. flavipes leucogaster: HT (Table 4). A. flavipes leucogaster skulls are also generally longer (BL, Dent) and broader (R-LC 1, R-LM 1 T, R-LM 2) than A. argentus .

Other Comments: A. argentus occurs in south-east Qld at Kroombit Tops NP, whereas A. flavipes leucogaster only occurs on the other side of the continent, in south-west Western Australia. Genetics: Uncorrected pairwise range differences at the mitochondrial gene CytB between A. argentus and A. flavipes leucogaster are 9.4–10.0%.
