Among them, Prolistrophorus (Aprolistrophorus) parabidentatus sp. nov. from Akodon azarae from Argentina and Prolistrophorus (Aprolistrophorus) tylomys sp. nov. from Tylomys nudicaudus from Guatemala are described as new for science. New hosts are recorded for the following species: Prolistrophorus (Prolistrophorus) grassii (Radford, 1954) from Zygodontomys brevicauda from Colombia, P. (P.) frontalis (Hirst, 1921) from Oligoryzomys sp. from Argentina, P. (P.) argentinus (Hirst, 1921) from Melanomys calig- inosus, Akodon affinis from Colombia and Scapteromys aquaticus from Argentina, Prolistrophorus (Beprolistrophorus) hirstianus Fain, 1973 from Scapteromys aquaticus from Argentina.

Aceptado 11-X-2012. Abstract: Biogeographic regionalization of the mammals of tropical evergreen forests in Mesoamerica. Mesoamerica is a biologically complex zone that expands from Southern Mexico to extreme Northern Colombia. The biogeographical patterns and relationships of the mammalian fauna associated to the Mesoamerican Tropical Evergreen Forest (MTEF) are poorly understood, in spite of the wide distribution of this kind of habitat in the region. We compiled a complete georeferenced database of mammalian species distributed in the MTEF of specimens from museum collections and scientific literature. This database was used to create potential distribution maps through the use of environmental niche models (ENMs) by using the Genetic Algorithm for Rule-Set Production (GARP) using 22 climatic and topographic layers. Each map was used as a representation of the geographic distribution of the species and all available maps were summed to obtain general patterns of species richness in the region. Also, the maps were used to construct a presence-absence matrix in a grid of squares of 0.5 degrees of side, that was analyzed in a Parsimony Analysis of Endemicity (PAE), which resulted in a hypothesis of the biogeographic scheme in the region.

Box 1346 Ann Arbor, Ml 48106-1346 ABSTRACT South American climbing mice and rats, Rhipidomys, occur in forests, plantations and rural dwellings throughout tropical South America. The genus belongs to the thomasomyine group, an informal assemblage of plesiomorphous Sigmodontinae. Over 1700 museum specimens were examined, with the aim of providing a coherent taxonomic framework for future work. A shortage of discrete and consistent characters prevented the use of strict cladistic methodology; instead, morphological assessments were supported by multivariate (especially principal components) analyses. The morphometric data were first assessed for measurement error, ontogenetic variation and sexual dimorphism; measurements with most variation from these sources were excluded from subsequent analyses. The genus is characterized by a combination of reddish-brown colour, long tufted tail, broad feet with long toes, long vibrissae and large eyes; the skull has a small zygomatic notch, squared or ridged supraorbital edges, large oval braincase and short palate.

Both series were founded by Dr. Bryant Walker, Mr. Bradshaw H. Swales, and Dr. W. W. Newcomb. The Occasional Papers, publication of which was begun in 1913, serve as a medium for original studies based principally upon the collections in the Museum. They are issued separately. When a sufficient number bf pages has been printed to make a volume, a title page, table of contents, and an index are supplied to libraries and individuals on the mail- ing list for the series. The Miscellaneous Publications. which include .DaDers . on field and museum tech- niques, monographic studies, and other contributions not within the scope of the Occa- sional Papers, are published separately.

  • Cricetidae: Sigmodontinae) with an Updated Summary of Valid Tribes and Their Generic Contents
    Occasional Papers Museum of Texas Tech University Number 338 15 July 2016 DESCRIPTION OF A NEW TRIBE OF SIGMODONTINE RODENTS (CRICETIDAE: SIGMODONTINAE) WITH AN UPDATED SUMMARY OF VALID TRIBES AND THEIR GENERIC CONTENTS JORGE SALAZAR-BRAVO, ULYSES F. J. PARDIÑAS, HORACIO ZEBALLOS, AND PABLO TETA ABSTRACT We provide a formal recognition to a tribal level clade composed of Andinomys and Puno- mys, two extant sigmodontine genera consistently and repeatedly recovered in the phylogenetic analyses of molecular and morphological data. As currently recognized, this tribe is distributed in middle to high elevations in the Andes of Bolivia, Peru, northern Chile, and northwestern Argentina in habitats that range from high elevation grasslands and ecotonal areas to dry Puna. Within this new clade, Punomys appears as the more specialized member as it is fully restricted to rocky outcrops and their immediate surrounding areas at elevations above 4400 m on both sides of the Altiplano. In contrast, Andinomys occupies a broad elevational range (500–4000 m) and multiple habitats, from subtropical mountain forests and semiarid Puna and Prepuna to high altitudinal grasslands. Both taxa share a number of possible synapomorphies (e.g., presence of caudal enlargement of the post-zygapophysis in the second and eighth thoracic vertebrates, unilocular-hemiglandular stomachs with a large corpus and deep incisura angularis, and very similar chromosomal complements) and other diagnostic morphological features. The supratribal phylogenetic relationships of the taxon here named are not resolved even with the moderate amount of molecular data now available. In addition, we present a revised classification for the Sigmodontinae and comment on the content and context of this unique radiation of the Cricetidae.

  • Rodentia) from South-Western Europe Since the Latest Middle Miocene to the Mio-Pliocene Boundary (MN 7/8–MN13)
    Ecomorphological characterization of murines and non-arvicoline cricetids (Rodentia) from south-western Europe since the latest Middle Miocene to the Mio-Pliocene boundary (MN 7/8–MN13) Ana R.

Álvarez-Sierra4,5 and Manuel Hernández Fernández4,5 1 Institut Català de Paleontologia Miquel Crusafont, Universitat Autónoma de Barcelona, Cerdanyola del Vallès, Barcelona, Spain 2 Transmitting Science, Barcelona, Spain 3 Department of Geology and Paleontology, National Museum of Nature and Science, Tokyo, Japan 4 Departamento de Paleontología, Facultad de Ciencias Geológicas, Universidad Complutense de Madrid, Madrid, Spain 5 Departamento de Cambio Medioambiental, Instituto de Geociencias (UCM, CSIC), Madrid, Spain ABSTRACT Rodents are the most speciose group of mammals and display a great ecological diversity. Despite the greater amount of ecomorphological information compiled for extant rodent species, studies usually lack of morphological data on dentition, which has led to difficulty in directly utilizing existing ecomorphological data of extant rodents for paleoecological reconstruction because teeth are the most common or often the only micromammal fossils. Here, we infer the environmental ranges of extinct rodent genera by extracting habitat information from extant relatives and linking it to extinct taxa based on the phenogram of the cluster analysis, in which variables are derived from the principal component analysis on outline shape of the upper first molars. This phenotypic ``bracketing'' approach is particularly useful in the study of the fossil record Submitted 22 February 2017 of small mammals, which is mostly represented by isolated teeth. As a case study, Accepted 13 July 2017 we utilize extinct genera of murines and non-arvicoline cricetids, ranging from the Published 25 September 2017 Iberoccitanian latest middle Miocene to the Mio-Pliocene boundary, and compare our Corresponding author results thoroughly with previous paleoecological reconstructions inferred by different Ana R.
