“…The above discoveries are consistent with and further strengthen the pattern revealed in previous studies in the Philippines (Esselstyn et al, 2009(Esselstyn et al, , 2011Heaney et al, 2009Heaney et al, , 2011Jansa et al, 2006Jansa et al, , 2009Musser and Heaney, 1992;Steppan et al, 2003) and other large, geologically old oceanic islands (e.g., Madagascar: Olson and Goodman, 2003;Yoder et al, 1996) that their mammalian biodiversity arose from extensive in situ diversification. The discoveries reported here further illustrate the insularizing effect of isolated mountaintops in the Philippines on the diversification of its murid rodents Heaney et al, 1989Heaney et al, , 2009Heaney et al, , 2011Heaney and Rickart, 1990;Rickart et al, 1998Rickart et al, , 2003Rickart et al, , 2005Steppan et al, 2003).…”

“…The sister taxon to these three genera is the genus Apomys, forest mice that also prefer soft-bodied invertebrates, but additionally feed on seeds and small fruits. These four genera form a clade that is endemic to the Philippines (referred to informally as the Chrotomys Division by Musser and Carleton, 2005, or as members of the Hydromyini within the Murinae by Aplin and Helgen, 2010; see also Jansa and Weksler, 2004;Rowe et al, 2008;Heaney et al, 2009), exhibiting spectacular ecological and morphological diversity, from small arboreal mice to ground-hopping, longsnouted, shrewlike rats. At least 45 species are currently known (Heaney et al, 2010.…”

Shrew mice of the genus Archboldomys are poorly known members of an endemic clade of vermivorous/insectivorous murid rodents confined to Luzon Island, Philippines. Three species of these small, ground-living, diurnal mice were previously known, all from a handful of specimens from a few localities. The pattern of morphological and genetic differentiation among additional specimens of shrew mice from our recent field surveys in the Central Cordillera and Sierra Madre mountains of Luzon document the presence of two distinct species groups within Archboldomys as previously defined, as well as three new species. Gene-sequence data from the mitochondrial cytochrome b and nuclear IRBP genes confirm the existence of six distinct species, but also show that Archboldomys, as previously defined, is composed of two clades that are not sister taxa. Reevaluation of the presumed morphological synapomorphies among these shrew mice, together with analyses of karyological and gene-sequence data, support the following: (1) erection of Soricomys, new genus; (2) transfer of A. kalinga and A. musseri to Soricomys; and (3) recognition of Archboldomys maximus,

“…Isarog (1966 m) supports two representatives of the cloud rat clade, P. cumingi and Batomys granti (Heaney et al, 1999), as does Mt. Banahaw (2177 m), with P. pallidus and Musseromys gulantang (Rosell, 1996;Heaney et al, 2009). Other mountains on Luzon that we surveyed each support only one species of Phloeomys.…”

“…Throughout the Indo‐Pacific, the complex distribution of the Murinae has been shaped by the history of dispersal, involving independent colonizations of different archipelagos (Jansa, Barker & Heaney, ; Rowe et al ., ). For example, in the Philippine murine assemblage (Heaney et al ., , ; Rickart et al ., ) at least five independent colonizations from the Asian continent occurred during the Neogene (Jansa et al ., ). Two additional colonizations of Sahul regions (Australia and New Guinea) led to the respective diversification of the Australo‐Papuan Hydromyini (Rowe et al ., ; Bryant et al ., ) and Rattus species (Taylor & Horner, ; Taylor, Calaby & Van Deusen, ; Robins et al ., ; Rowe et al ., ).…”

A new genus of rodent from Wallacea (Rodentia: Muridae: Murinae: Rattini), and its implication for biogeography and Indo-Pacific Rattini systematics

We describe Halmaheramys bokimekot Fabre, Pagès, Musser, Fitriana, Semiadi & Helgen gen. et sp. nov., a new genus and species of murine rodent from the North Moluccas, and study its phylogenetic placement using both molecular and morphological data. We generated a densely sampled mitochondrial and nuclear DNA data set that included most genera of Indo-Pacific Murinae, and used probabilistic methodologies to infer their phylogenetic relationships. To reconstruct their biogeographical history, we first dated the topology and then used a Lagrange analysis to infer ancestral geographic areas. Finally, we combined the ancestral area reconstructions with temporal information to compare patterns of murine colonization among Indo-Pacific archipelagos. We provide a new and comprehensive molecular phylogenetic reconstruction for Indo-Pacific Murinae, with a focus on the Rattus division. Using previous results and those presented in this study, we define a new Indo-Pacific group within the Rattus division, composed of Bullimus, Bunomys, Paruromys, Halmaheramys, Sundamys, and Taeromys. Our phylogenetic reconstructions revealed a relatively recent diversification from the Middle Miocene to Plio-Pleistocene associated with several major dispersal events. We identified two independent Indo-Pacific dispersal events from both western and eastern Indo-Pacific archipelagos to the isolated island of Halmahera, which led to the speciations of H. bokimekot gen. et sp. nov. and Rattus morotaiensis Kellogg, 1945. We propose that a Middle Miocene collision between the Halmahera and Sangihe arcs may have been responsible for the arrival of the ancestor of Halmaheramys to eastern Wallacea. Halmaheramys bokimekot gen. et sp. nov. is described in detail, and its systematics and biogeography are documented and illustrated.
