“…Furthermore, our specimen can be identified as C. unduaviensis by the following combination of characters: tail length more than 111 mm (Table 2), condylobasal length more than 25.5 mm, maxillary too throw more than 10.0 mm, length of upper molar series (M1-M4) more than 5.5 mm; venter self-colored light yellowish buff. The characters and measurements of our specimen fell within the range of variation described for C. unduaviensis in the literature Gardner, 2007b;Voss & Jansa, 2009;Voss, com. pers.…”

“…There was no significant difference between bones found in the white-eared opossum skull when compared with those described for other mammals, as of porcupine (Yilmaz 1998), ferret (He et al 2002), and dog (Dyce et al 2010). Voss & Jansa (2009) reported presence of the jugal bone in the marsupial Marmosa murina. However, in this study we have not identified the jugal and mastoid bones.…”

Anatomical and radiographic study of the white-eared opossum (Didelphis albiventris) skull1

This study was made to investigate the anatomical features of the white-eared opossum skull, by osteology and radiographic anatomy. For this, five animals were used without sexual distinction. The skull was examined by radiographic and macroscopic characteristics. The skulls were then subjected to maceration. The skull was described macroscopically according to standard views, i.e. dorsal and caudal, lateral, ventral, and midsagittal. The skull can be divided into facial (viscerocranium) and cranial (neurocranium) regions. The facial region was elongated and more developed than neurocranium. The supraorbital foramen was absent. The tympanic bulla is not well developed. The zygomatic arch was formed by zygomatic process of the temporal bone, zygomatic process of the maxilla, and temporal process of the zygomatic bone. There was no significant difference between bones found in this study when compared with those described for others mammals. These findings may contribute to the better understanding of the anatomy and biology of the white-eared opossum.

“…Laboratory Methods: We extracted DNA from preserved tissues or dried museum specimens using methods described in Voss and Jansa (2009) and Giarla et al (2010). To minimize risk of contamination, all extractions from museum specimens were performed in an isolated laboratory where mammalian polymerase chain reaction (PCR) products were not present.…”

“…To minimize risk of contamination, all extractions from museum specimens were performed in an isolated laboratory where mammalian polymerase chain reaction (PCR) products were not present. We PCR-amplified six loci for this study (CYTB, BRCA1, IRBP, OGT, SLC38, and Anon128) using the primers listed in appendix 2 and methods described in Voss and Jansa (2009), Giarla et al (2010Giarla et al ( , 2014, Gutiérrez et al (2010), and Pavan et al (2014). The resulting PCR products were Sanger-sequenced on an ABI 3730xl automated sequencer.…”

This is the first installment of a revision of the didelphid marsupial genus Philander, commonly known as gray four-eyed opossums. Although abundant and widespread in lowland tropical forests from southern Mexico to northern Argentina, species of Philander are not well understood taxonomically, and the current literature includes many examples of conflicting species definitions and nomenclatural usage. Our revision is based on coalescent analyses of mitochondrial gene sequences, phylogenetic analyses of mitochondrial and nuclear genes, morphometric analyses, and firsthand examination of relevant type material. Based on these results, we provisionally recognize eight species, of which three are formally treated in this report: P. quica (Temminck, 1824), an Atlantic Forest endemic formerly known as P. frenatus (Olfers, 1818); P. canus (Osgood, 1913), a widespread species formerly treated as a synonym or subspecies of P. opossum (Linnaeus, 1758); and P. pebas, a new species endemic to Amazonia. The remaining, possibly valid, species of Philander can be allocated to two clades. The first is a cis-Andean complex that includes P. andersoni (Osgood, 1913); P. mcilhennyi Gardner and Patton, 1972; and P. opossum. The second is a transAndean complex that includes P. melanurus (Thomas, 1899) and P. pallidus (Allen, 1901). Among other nomenclatural acts, we designate a neotype for the long-problematic nominal taxon Didelphis superciliaris Olfers, 1818, and (in an appendix coauthored by Renate Angermann), we establish that Olfers' coeval binomen D. frenata is based on an eastern Amazonian type and is a junior synonym of P. opossum.
