Abstract Karyotypes of Hapalomys delacouri (Rodentia, Muridae) and Typhlomys cinereus (Rodentia, Platacanthomyidae) from Vietnam are described for the first time. The diploid karyotype of Hapalomys delacouri is 38 (NFa=48), consisting of six pairs of bi-armed and 12 pairs of acrocentric autosomes decreasing in size; plus a large metacentric X chromosome and Y chromosome, also metacentric, that is equal in size to the largest pair of acrocentric autosomes. The newly described karyotype differs… 
An enigmatic pygmy dormouse: molecular and morphological evidence for the species taxonomic status of Typhlomys chapensis (Rodentia: Platacanthomyidae)
Both genetic and morphological data confirm that there is a second species of pygmy dormouse, Typhlomys chapensis, in the heretofore monotypic genus Typhlombys, which is based on both morphology and sequence data.
Evidence of a complex phylogeographic structure in the Indomalayan pencil-tailed tree mouse Chiropodomys gliroides (Rodentia: Muridae) in eastern Indochina
The first phylogeography of the Indomalayan pencil-tailed tree mouse, Chiropodomys gliroides, reveals the existence of two highly divergent allopatric lineages showing a genetic divergence of 12% cyt b and occurring in different regions of Vietnam.
Acariform mites (Acariformes) - permanent symbionts of Hapalomys delacouri Thomas (Rodentia, Muridae) in Vietnam
It is shown that species of both mite genera associated with Hapalomys Blyth do not demonstrate clear phylogenetic links with respective congeners from rodents of the closest genus Chiropodomys Peters.
Molecular and morphological evidence for a new species of the genus Typhlomys (Rodentia: Platacanthomyidae)
Morphological and molecular analyses supported the designation of the Huangshan specimens found at mid-elevations in the southern HuangShan Mountains (600 m to 1 200 m a.s.l.) as a new species.
Nucleolar organizer regions of the Indomalayan Pencil-tailed Tree Mouse Chiropodomys gliroides (Rodentia: Muridae)
The chromosome complement of Chiropodomys gliroides from Peninsular Malaysia consists of two pairs of nucleolar organizer regions (NORs) – the longest acrocentric pair and the small metacentric. The
A new Hapalomys species from Vietnam New insights into the taxonomy of the marmoset rats Hapalomys ( Rodentia : Muridae )
A new species of marmoset rat, Hapalomys suntsovi, is described from Binh Phuoc Province, southern Vietnam. The species seems to be endemic to Vietnam. It is diagnosed on the basis of cranial
Murine rodents (Rodentia: Murinae) of the Myanmar-Thai-Malaysian peninsula and Singapore: taxonomy, distribution, ecology, conservation status, and illustrated identification keys
This paper incoiporates a detailed summary of past research, 1851-2013, of the Murinae in the study area and includes descriptive characters of the external, cranial and dental morphology and measurements for each of the rodent species.
New data on the distribution and intraspecific variation of the Millard’s giant rat Dacnomys millardi (Mammalia, Rodentia) from Vietnam
An analysis of a genetic and morphological variation of Dacnomys millardi from seven Vietnamese localities, including a new finding from southern Vietnam which lies some 1000 km to the south of the currently known limit of the species range, finds a low overall genetic diversity.
A blind climber: The first evidence of ultrasonic echolocation in arboreal mammals.
Findings of locomotion-associated ultrasonic vocalization in a fast-climbing but weakly-sighted small mammal ecotype add support to the "echolocation-first theory" of pre-flight origin of echolocation in bats.
Naturalists, Explorers and Field Scientists in South-East Asia and Australasia
Alfred Russel Wallace is well-known for his co-discovery of the principle of natural selection. Natural selection is usually considered a process, but it is not clear that Wallace regarded it in


Unusually extensive karyotype reorganization in four congeneric Gerbillus species (Muridae: Gerbillinae)
This study revealed that possibly 70 Robertsonian (Rb) fusions, two pericentric inversions, one tandem translocation and at least 13 non-identified rearrangements have occurred during the karyotypic evolution of these species.
Karyotype Reorganisation in the subtilis Group of Birch Mice (Rodentia, Dipodidae, Sicista): Unexpected Taxonomic Diversity within a Limited Distribution
A phylogenetic scenario inferred from a cladistic analysis of the chromosomal data suggests that the extensive karyotypic diversification within the subtilis group in the south-east region of the Russian Plain most likely results from fragmentation of a continuously distributed, ancestral population.
Chromosomal characterization of Arvicanthis species (Rodentia, Murinae) from western and central Africa: implications for taxonomy
A chromosome study of unstriped grass rats of the genus Arvicanthis in western and central Africa is presented and a G- and C-banded chromosome nomenclature that allows easy species identification is developed.
The Species of Hapalomys ( Rodentia , Muridae ) BY
Rats of the genus Hapalomys are adapted for arboreal life and live in the forests of Southeast Asia. Current published opinions regarding taxonomy of Hapalomys claim there is only one polytypic
Karyotypes of Hapalomys and Pithecheir (rodentia: Muridae) from peninsular Malaysia.
The karyotypes of two Malaysian murids Hapalomys longicaudatus Blyth and Pithecheir melanurus parvus Kloss are reported and are compared with those of two closely related genera, Lenothrix and Chiropodomys.
Systematics and phylogeny of West African gerbils of the genus Gerbilliscus (Muridae: Gerbillinae) inferred from comparative G- and C-banding chromosomal analyses
The pattern of phylogenetic relationships inferred from a cladistic analysis of the chromosomal data is in good agreement with recent molecular phylogenetic studies that recognize a West African species group within the genus Gerbilliscus, and the monophyly of both GerbillISCus and Gerbillurus.
The Phylogenetic Position of the Rodent Genus Typhlomys and the Geographic Origin of Muroidea
It is concluded that both Myodonta and Muroidea originated in Eurasia and that the 3 earliest divergences within Muroida were restricted to the Eurasian supercontinent, supporting the view that global muroid diversity resulted from independent radiations in separate continental regions.
Mitochondrial diversity of the white-toothed shrews (Mammalia, Eulipotyphla, Crocidura) in Vietnam
The discovery of fairly deep genetic divergences among Vietnamese Crocidura illustrates that the understudied and largely undescribed diversity of white-toothed shrews in Southeast Asia requires deeper scrutiny and shows the useful insights of mitochondrial markers as to the taxonomic resolution of this enigmatic group of mammals.
New karyotypic data for Asian rodents (Rodentia, Muridae) with the first report of B-chromosomes in the genus Mus
Few species-specific chromosomal characteristic could be identified within most of the genera investigated in this study and, in contrast to previous claims, the usefulness of karyotypes for diagnosing these Asian murid species appears to be limited.
A new species of Crocidura (Soricomorpha: Soricidae) from southern Vietnam and north-eastern Cambodia
A new species of white-toothed shrew belonging to the genus Crocidura is described from lowland areas in southern Vietnam and from a river valley in north-eastern Cambodia on the basis of external features, cranial proportions and morphology of the last upper and lower molars.
