Abstract. The type material of Oryzomys curasoae McFarlane and Debrot, 2001, an allegedly extinct species from the island of Curaçao, Netherlands Antilles, is morphologically indistinguishable from O. gorgasi Hershkovitz, 1971, a Recent mangrove-inhabiting species from mainland Venezuela. A phylogenetic analysis suggests that the latter belongs to the genus Oryzomys in its strictest sense, and that “curasoae” is not close to Oecomys (formerly ranked as a subgenus of Oryzomys) as previously… 
New rodents (Cricetidae) from the Neogene of Curaçao and Bonaire, Dutch Antilles
Cordimus, a new genus of cricetid rodent, is described from Neogene deposits on the islands of Curaçao and Bonaire, Dutch Antilles and may be close to the root of the sigmodontine lineage, a possibility that remains to be tested through explicit phylogenetic analysis.
A newly recognized clade of trans-Andean Oryzomyini (Rodentia: Cricetidae), with description of a new genus
H aphrastus is best regarded as representing a new genus, which is described and named herein and forms a monophyletic group of mainly southern Central American and northern South American taxa primarily restricted to lowland to midelevation montane trans-Andean habitats and possessing a marked ability to cross expanses of salt water.
Taxonomy, phylogeny, and diversity of the extinct Lesser Antillean rice rats (Sigmodontinae: Oryzomyini), with description of a new genus and species
Megalomys and Pennatomys belong to an oryzomyine clade that has undergone remarkable radiation throughout the oceanic and continental-shelf islands of the Neotropical region, but these genera do not represent a monophyletic group within the Nectomys subclade, indicating multiple over-water colonization events of the Lesser Antillean island chain.
A new genus of oryzomyine rodents (Cricetidae, Sigmodontinae) with three new species from montane cloud forests, western Andean cordillera of Colombia and Ecuador
A medium-sized oryzomyine is described as a new genus having at least three new species, two of them named and diagnosed, and seems to be another example of a sigmodontine rodent unique to the Chocó biogeographic region.
A new genus and species of rodent from the Brazilian Atlantic Forest (Rodentia: Cricetidae: Sigmodontinae: Oryzomyini), with comments on oryzomyine biogeography
A new genus and species of cricetid rodent from the Atlantic Forest of Brazil, one of the most endangered eco-regions of the world, is described, which displays some but not all synapomorphies of the tribe Oryzomyini.
Natural History Observations of the Ichthyological and Herpetological Fauna on the Island of Curaçao (Netherlands)
The first report of avian predation on the endemic Curaçao whiptail lizard, Cnemidophorus murinus, is presented, suggesting these lizards play a potentially important role in this island's food web.
Geographic distribution of the genera of the Tribe Oryzomyini (Rodentia: Cricetidae: Sigmodontinae) in South America: patterns of distribution and diversity
The Oryzomyini is the most diverse tribe of the sigmodontine (Cricetidae: Sigmodontinae) radiation, including 28 genera and about 130 species, with this diversity reflected in the ecological and
New genus and two new species of Pleistocene oryzomyines (Cricetidae: Sigmodontinae) from Bonaire, Netherlands Antilles
A collection of about 500 molars from 5 Pleistocene localities on the island of Bonaire is reidentified as representing a new genus and 2 new species of oryzomyine rodents based on comparative examination and phylogenetic analysis of morphological characters.


Redescription of the enigmatic long-tailed rat Sigmodontomys aphrastus (Cricetidae: Sigmodontinae) with comments on taxonomy and natural history
The phylogenetic relatedness of S. aphrastus with purported sister taxa remains unresolved until combined molecular and morphological analyses are conducted.
Ten New Genera of Oryzomyine Rodents (Cricetidae: Sigmodontinae)
10 new genera are described for species or species groups previously referred to the polyphyletic genus Oryzomys, and the tribe OryZomyini now comprises 28 genera, which are morphologically diagnosable and have distinct ecogeographic distributions.

Phylogenetic Relationships of Oryzomine Rodents (Muroidea: Sigmodontinae): Separate and Combined Analyses of Morphological and Molecular Data
A phylogenetic hypothesis for the tribe Oryzomyini is provided that can be used to understand the diversification and evolution of this group of rodents and to revise the current generic-level classification.
A New Species of Extinct Oryzomyine Rodent from the Quaternary of Curacao, Netherlands Antilles
An extinct new species of Oryzomyine rodent, known since 1936 from the cave of Grot van Hato on the island of Curacao, is described from abundant new specimens collected from owl-pellet deposits at
Rediscovery of Oryzomys gorgasi (Rodentia : Muridae). With Notes on Taxonomy and Natural History
La survie de ce rongeur, apparemment peu commun au Venezuela et d'ecologie restreinte, peut etre menacee par la competition avec Rattus rattus and par the degradation acceleree de son milieu par l'homme.

Cladistic analysis of amino acid sequence data, including evaluation of all equally or almost equally parsimonious cladograms, shows that much homoplasy (parallelisms and reversals) is present and that few or no well supported monophyletic groups of families can be demonstrated.
Evaluation of the maximum likelihood estimate of the evolutionary tree topologies from DNA sequence data, and the branching order in hominoidea
A new method for estimating the variance of the difference between log likelihood of different tree topologies is developed by expressing it explicitly in order to evaluate the maximum likelihood branching order among Hominoidea.
Polymorphic Characters in Phylogenetic Systematics
This study supports the traditional view that polymorphic characters are less reliable in inferring phylogeny but does not necessarily support their exclusion, and reviews the problem of using discrete, intraspecifically variable characters in parsimony analysis.
