Craniodental Morphology and Phylogeny of Marsupials
The current literature on marsupial phylogenetics includes numerous studies based on analyses of morphological data with limited sampling of Recent and fossil taxa, and many studies based on analyses of molecular data with dense sampling of Recent taxa, but few studies have combined both data types. Another dichotomy in the marsupial phylogenetic literature is between studies focused on New World taxa and those focused on Sahulian taxa. To date, …
A Revision of the Didelphid Marsupial Genus MarmosaPart 2. Species of the Rapposa Group (Subgenus Micoureus)
In this report, the second of a revisionary series on mouse opossums (Marmosa), we analyze cytochrome b sequence data from 166 specimens of the subgenus Micoureus and delimit putative species using the multirate Poisson Tree Processes (mPTP) method. That analysis identifies 21 putative species, many of which can be matched with available names, including alstoni, constantiae, demerarae, limae, germana, meridae, paraguayana, parda, perplexa, phaea…
A Review of the Eliurus tanala Complex (Rodentia: (Muroidea: Nesomyidae), with Description of a New Species from Dry Forests of Western Madagascar
Based on 372 specimens examined, we integrated information from two mitochondrial and four nuclear gene sequences, morphological comparisons and morphometric analyses, as well as distributional patterns and ecological occurrences to revise the Eliurus tanala species group (Nesomyinae), a rodent complex endemic to Madagascar's forests. These evidentiary sources generally proved concordant, supporting description of a new species, E. tsingimbato, i…
Mammalian Diversity and Matses Ethnomammalogy in Amazonian Peru Part 3: Marsupials (Didelphimorphia)
This report is the third in our monographic series on mammalian diversity and Matses ethnomammalogy in the Yavarí-Ucayali interfluvial region of northeastern Peru. Based on taxonomic analysis of specimens collected in the region, we document the occurrence of 19 species of marsupials in the genera Caluromys, Glironia, Hyladelphys, Marmosa, Monodelphis, Metachirus, Chironectes, Didelphis, Philander, Gracilinanus, and Marmosops. Our principal taxon…
Species Limits and Phylogenetic Relationships in the Didelphid Marsupial Genus Thylamys Based on Mitochondrial DNA Sequences and Morphology
Species of the didelphid marsupial genus Thylamys, commonly known as fat-tailed mouse opossums, are broadly distributed in the open habitats of central and southern South America. In this report we examine species limits in the genus and infer phylogenetic relationships among Thylamys species using both molecular phylogenetic and morphological methods. We assessed species limits using a broad geographic sample of DNA sequences from the mitochondr…
Chapter 7. A New Genus and Species of Small ‘Tree-Mouse’ (Rodentia, Muridae) Related to the Philippine Giant Cloud Rats
A single specimen of a small mouse from Mt. Banahaw–San Cristobal Natural Park, Quezon Province, Luzon Island, Philippines, is here described as a new genus and species. It is easily distinguished from all other murids by its small size (15 g), rusty orange fur, mystacial vibrissae that are two-thirds the length of head and body, postocular patch of bare skin with long vibrissae arising within it, long tail with elongated hairs only on the poster…
Phylogenetic Relationships and Classification of Didelphid Marsupials, an Extant Radiation of New World Metatherian Mammals
This report summarizes a decade of morphological and molecular research on the phylogenetic relationships of didelphid marsupials (opossums), a substantially intact radiation of New World metatherian mammals. We review the comparative morphology of Recent opossums, emphasizing those anatomical systems from which taxonomically useful information is available for the majority of living genera and species, namely the integument, cranium, and dentiti…
