“…However, such morphology-based subdivisions have contributed little but taxonomic confusion (Pine et al, 2013), and none is convincingly supported by character data. By contrast, recent molecular phylogenetic studies based on dense taxonomic sampling and multiple unlinked genes (Pavan et al, 2014;Vilela et al, 2015;Pavan et al, 2016) have consistently recovered several robustly supported multispecies clades (table 1), and some morphological studies (e.g., Voss et al, 2012;Pavan, 2015) suggest that at least some of the groups recovered by molecular phylogenetic research are morphologically diagnosable.…”

“…Monodelphis Burnett, 1830, is the most speciose genus of didelphid marsupials, with 22 currently recognized species (Pavan et al, 2014;Pavan, 2015). Insofar as known, species of Monodelphis are terrestrial or semifossorial, predominantly insectivorous opossums that exhibit conspicuous variation in pelage coloration, behavior, and reproductive strategies (Streilein, 1982a(Streilein, , 1982bEmmons and Feer, 1997;Pine et al, 1985;Pine and Handley, 2008).…”

“…For example, the monophyletic group that Pavan et al (2014) called "Clade E" corresponds to the "Adusta Group" of Pavan et al (2016) and to the combined adusta and kunsi "complexes" of Vilela et al (2015). Formally diagnosing and naming such groups has the advantage that usage is constrained by typification and priority according to widely accepted rules (ICZN, 1999), and ranking these clades as subgenera promotes stability by preserving long-established binomial combinations.…”

Members of the didelphid marsupial genus Monodelphis have previously been classified into species groups, but such informal subdivisions are inconsistent among authors and have contributed little but confusion to the taxonomic history of the genus. Recent molecular phylogenetic studies, however, have consistently recovered several strongly supported multispecies clades that merit formal recognition. Here we define and illustrate morphological characters that are useful for diagnosing these monophyletic groups, which we name and rank as subgenera to conserve binomial usage: Monodelphis Burnett, 1830 (for M. arlindoi, M. brevicaudata, M. domestica, M. glirina, M. palliolata, M. sanctaerosae, and M. touan), Microdelphys Burmeister, 1856 (for M. americana, M. gardneri, M. iheringi, and M. scalops), Monodelphiops Matschie, 1916 (for M. dimidiata and M. unistriata); Mygalodelphys, new subgenus (for M. adusta, M. handleyi, M. kunsi, M. osgoodi, M. peruviana, M. pinocchio, M. reigi, and M. ronaldi); and Pyrodelphys, new subgenus (for M. emiliae). We provide morphological diagnoses and describe pairwise comparisons to facilitate subgeneric identification, and we summarize subgeneric patterns of geographical distribution and sympatry to supplement recently published biogeographic analyses of the genus.

“…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.

“…The current classification formally recognizes 17 valid species of Marmosops, a total that includes the 15 species recognized by Gardner and Creighton (2008) and two others subsequently described as new (Voss et al, 2013;García et al, 2014). Among other didelphid genera, only Monodelphis (with 22 currently recognized species; Pavan et al, 2014;Pavan, 2015) and Marmosa (with 19 species; Voss et al, 2014) are comparably diverse.…”
