FIGURE 20 in A new dasyurid marsupial from Kroombit Tops, south-east Queensland, Australia: the Silver-headed Antechinus, Antechinus argentus sp. nov. (Marsupialia: Dasyuridae)

FIGURE 20. Distribution of small mammal trapping effort (Elliott trap nights) on Kroombit Tops. The size of the red dots are proportional to trap effort (trap nights) undertaken at the site, blue lines are drainages, the orange line is the 800 m contour and the green shading is Kroombit Tops National Park. Capture sites (n=2) for Antechinus argentus are indicated by a black triangle with the black arrow pointing to the type locality. The capture site for A. flavipes flavipes is indicated with a black cross. The inset shows eastern Australia, with the position of Kroombit Tops marked (red square).
