Kurzfassung:
The woolly flying squirrel, Eupetaurus cinereus, is among the rarest and least studied mammals in the world. For much of the 20th century it was thought to be extinct, until it was rediscovered in 1994 in northern Pakistan. This study outlines the first taxonomic and biogeographical review of the genus Eupetaurus, which until now has contained only a single species. Careful review of museum specimens and published records of Eupetaurus demonstrates that the genus occurs in three widely disjunct areas situated on the western (northern Pakistan and north-western India), north-central (south-central Tibet, northern Sikkim and western Bhutan) and south-eastern margins (north-western Yunnan, China) of the Himalayas. Taxonomic differentiation between these apparently allopatric populations of Eupetaurus was assessed with an integrative approach involving both morphological examinations and molecular phylogenetic analyses. Phylogenetic reconstruction was implemented using sequences of three mitochondrial [cytochrome b (Cytb), mitochondrially encoded 12S and 16S ribosomal RNA (12S, 16S)] and one nuclear [interphotoreceptor retinoid-binding protein (IRBP)] gene fragment. Morphological assessments involved qualitative examinations of features preserved on museum skins and skulls, supplemented with principal components analysis of craniometric data. Based on genetic and morphological comparisons, we suggest that the three widely disjunct populations of Eupetaurus are each sufficiently differentiated genetically and morphologically to be recognized as distinct species, two of which are described here as new.
