Figure 3 in Using 3D geometric morphometrics to aid taxonomic and ecological understanding of a recent speciation event within a small Australian marsupial (Antechinus: Dasyuridae)
Figure 3. Pairwise comparisons between mean shapes of each clade (Antechinus stuartii south vs. A. stuartii north, P = 0.003; A. stuartii north vs. A. subtropicus, P = 0.003; A. stuartii south vs. A. subtropicus, P = 0.003; all p-values were adjusted with following the Bonferroni method). The 3D images are the specimen closest to the overall mean warped correspondingly to the mean shapes of each clade. Tukey post-hoc analyses of linear measurements after size correction were performed; significance levels (*P <0.05, **P <0.01, ***P <0.001) are shown in the boxplots. For each comparison, we have labelled the best differentiator diagnostic; i.e. the size of the major palatine foramina (mapf) for differentiating A. stuartii south and A. stuartii north, the size of the incisive foramina (inf) for differentiating A. stuartii north and A. subtropicus, and the interpalatal distance (intp) for differentiating between the three clades. Clades are consistently labelled as per Figure 1.

Figure 1. Distribution map of the specimens used for this study. Labelled are Antechinus stuartii south, A. stuartii north, A. subtropicus, specimens of unknown identity within the A. stuartii–A. subtropicus species complex, the holotype of A. subtropicus and the neotype of A. stuartii. All figures in this paper are labelled: A. stuartii south in orange, A. stuartii north in pink and A. subtropicus in green. The phylogeny is adapted from Mutton et al. (2019).

Figure 2. A, box plot and dot plot of centroid size labelling each clade as per Figure 1. Centroid size differences were clear only between the larger Antechinus subtropicus and the smaller A. stuartii (both mean comparisons between A. subtropicus and the two clades of A. stuartii were significant; P = 0.003), but not between A. stuartii south and A. stuartii north (P = 0.282). B, allometry plot consisting of centroid sizes versus shape scores obtained from the regression of shape on size (Drake & Klingenberg, 2008).

FIGURE 16. Cranium (A, C–E) and dentary (B and F) of the holotype Planigale tealei (WAM M47923). Cranium shown in ventral (A), dorsal (C), posterior (D) and lateral (E) views, and dentary pictured in occlusal (B) and buccal (F) views. Note shallower and broader u-shaped posterior suture of nasals, broader interorbital region and overall smaller skull size compared to P. kendricki.

FIGURE 8. A in Hiding in plain sight: two new species of diminutive marsupial (Dasyuridae: Planigale) from the Pilbara, Australia
FIGURE 8. A) CDA on the craniodental measurement data where size has been accounted for, for Planigale 1, P. maculata, P. ingrami and P. sp. Mt Tom Price, note males and females shown as closed and open symbols, respectively. Character contributions to canonical axes 1 and 2 as total canonical structure coefficients. Axes not scaled accordingly.
FIGURE 7. A in Hiding in plain sight: two new species of diminutive marsupial (Dasyuridae: Planigale) from the Pilbara, Australia
FIGURE 7. A) Comparison of overall skull size (geometric mean) between male and female planigales from four species, Planigale ingrami, P. Mt Tom Price, Planigale 1 and P. maculata. All pairwise comparisons had p <0.0001 unless indicated otherwise (p> 0.05, ns; p <0.05, *; p <0.001, **). B) and C) comparisons of selected cranial measurements (in mm) for Planigale ingrami, P. maculata, Planigale 1 and P. sp. Mt Tom Price, closed symbols are males, open symbols are females. B) overall skull size using basicranial skull length and zygomatic width; C) length of nasals vs. braincase height, which demonstrates separation of the two Pilbara planigale lineages.
FIGURE 6 in Hiding in plain sight: two new species of diminutive marsupial (Dasyuridae: Planigale) from the Pilbara, Australia
FIGURE 6. PCA on the craniodental measurement data for Planigale in this study, males are closed symbols and females open symbols (note sex is not indicated for Planigale gilesi and P. tenuirostris). A) PCA before skull size has been accounted for, variation explained by PC1 axis can be interpreted as size, and B) character loadings (eigenvectors) showing the contribution of each measurement variable to PC1 and PC2. C) PCA and D) character loadings after skull size has been accounted for, less variation is explained by PC1 and with size continuing to influence PC1. PCA axes are not scaled accordingly. Note both before and after size correction there is no overlap in the distribution of samples of the two Pilbara forms.
