FIG. 14 in A Revised Subgeneric Classification of Short-tailed Opossums (Didelphidae: Monodelphis)

FIG. 14. Dorsal (A) and ventral (B) views of a freshly killed specimen of Monodelphis (Pyrodelphys) emiliae, illustrating the diagnostically flame-colored ventral pelage (photo courtesy of M. Hoogmoed). Whereas the dorsal coloration of this species is faithfully preserved even in decades-old museum skins, the ventral coloration quickly fades aπer death.

FIG. 12 in A Revised Subgeneric Classification of Short-tailed Opossums (Didelphidae: Monodelphis)

FIG. 12. Lingual view of the unworn right mandibular dentition of Monodelphis scalops (A, FMNH BDP3282) and M. handleyi (B, AMNH 276704), illustrating taxonomic differences in size of the entoconid (arrows) on m1–m3 (see text). Scale bars = 2 mm.

FIG. 4 in A Revised Subgeneric Classification of Short-tailed Opossums (Didelphidae: Monodelphis)

FIG. 4. Close-up views of tail illustrating caudal scales arranged in annular series (A, Monodelphis glirina, MZUSP MTR 10164) and spiral series (B, M. dimidiata, MZUSP 34257). Not to the same scale.

FIG. 9 in A Revised Subgeneric Classification of Short-tailed Opossums (Didelphidae: Monodelphis)

FIG. 9. Ventral cranial view of old adult males of Monodelphis touan (A, USNM 393441) and M. americana (B, UFMG 2004), illustrating the presence of an infratemporal crest of alisphenoid (ica) in M. touan. The crest is absent or indistinct in M. americana. Scale bars = 5 mm.

FIG. 6 in A Revised Subgeneric Classification of Short-tailed Opossums (Didelphidae: Monodelphis)

FIG. 6. Leπ lateral cranial view of Monodelphis peruviana (A, FMNH 172032), M. emiliae (B, MUSM 13298), and M. americana (C, OK 17381) illustrating taxonomic differences in zygomatic morphology. In M. peruviana the jugal (jug) is not produced dorsal to the zygomatic process of the squamosal (zps) and the frontal process is absent or indistinct. By contrast, in M. emiliae a rounded frontal process of the jugal (fpj) extends dorsal to the zygomatic process of the squamosal, whereas in M. americana the frontal process of the jugal is well devel-oped and distinctly angular. Not to the same scale.

FIG. 13. Phylogenetic hypotheses for species of Monodelphis based on maximum-likelihood, maximum-parsimony, and Bayesian analyses (A, aπer Pavan et al., 2014) and coalescent analyses (B, aπer Pavan et al., 2016) of DNA sequence data from one mitochondrial and four nuclear genes.

FIGURE 1 in A new species of Monodelphis (Didelphimorphia: Didelphidae) from the Brazilian Atlantic Forest

FIGURE 1. Phylogenetic relationships of species of the Monodelphis adusta group based on a maximumlikelihood analysis of DNA sequence data from one mitochondrial and four nuclear genes (4983 aligned sites; after Pavan et al., 2014). Support statistics from maximum-parsimony (MP) and maximum-likelihood (ML) bootstrap analyses are indicated at each resolved node along with Bayesian posterior probabilities (BPP). White wedges indicate MP and ML bootstrap frequencies ≤ 50%, gray indicates bootstrap frequencies between 50% and 75%, and black indicates bootstrap frequencies ≥ 75%. For Bayesian statistics, white indicates BPP <0.95, whereas black indicates BPP ≥ 0.95. See Pavan et al. (2014:201, 202) for methodological details.
