Item Archboldomys (Muridae, Murinae) reconsidered : a new genus and three new species of shrew mice from Luzon Island, Philippines. (American Museum novitates, no. 3754)(American Museum of Natural History., 2012-09-14) Balete, Danilo S., 1960-; Rickart, Eric A.; Heaney, Lawrence R.; Alviola, Phillip A.; Duya, Melizar V.; Duya, Mariano Roy M.; Sosa, Timothy.; Jansa, Sharon A.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, n. sp., Soricomys leonardocoi, n. sp., and Soricomys montanus, n. sp. The new genus and species are described, and their phylogenetic relationships, biogeography, and conservation are discussed.Item Contributions to mammalogy in honor of Karl F. Koopman.

American Museum novitates ; no. 2821(New York, N.Y. : American Museum of Natural History, 1985) Musser, Guy G.; Heaney, Lawrence R.; Rabor, Dioscoro S."Crateromys australis, new species, is described from one specimen collected on Dinagat, a small island north of Mindanao, Republic of the Philippines. The new rat is contrasted with the larger-bodied C. schadenbergi, which is endemic to Luzon, and the smaller C. paulus, the only native muroid recorded from Ilin Island. A discussion of the three species is set against the native mammals of Dinagat and the native Philippine murids"--P. [1].Item Philippine Rattus : a new species from the Sulu Archipelago. American Museum novitates ; no. 2818(New York, N.Y. : American Museum of Natural History, 1985) Musser, Guy G.; Heaney, Lawrence R."A new species, Rattus tawitawiensis, is described from Tawitawi Island in the southern Sulu Islands. It is native to the island, whereas Rattus rattus mindanensis, which also occurs there, is not. The known mammalian fauna of the Sulu Archipelago has characteristics indicating that the islands have had no recent land-bridge connection to either Borneo or Mindanao; this is consistent with geological evidence. The new species has no close relative now living in either the Philippine Islands to the east or on the islands and peninsula of the Sunda Shelf to the west. In morphology, the Tawitawi rat is most similar to species of Rattus living on islands rimming the Sunda Shelf beyond the 180 m bathymetric line. These peripheral isolates appear to be most similar to Rattus tiomanicaus among the extant fauna of the Sunda Shelf"--P. [1].Item Philippine rodents : definitions of Tarsomys and Limnomys plus a preliminary assessment of phylogenetic patterns among native Philippine murines (Murinae, Muridae). Bulletin of the AMNH ; no. 211([New York] : American Museum of Natural History, 1992) Musser, Guy G.; Heaney, Lawrence R."Species of Tarsomys and Limnomys are found only on the island of Mindanao in the Philippine Archipelago. Both genera were named by Mearns in 1905 but never adequately diagnosed or described, a situation we rectify in this report. Tarsomys contains the type species, T. apoensis, which has been collected only from tropical lower and upper montane rain forest between 5200 and 7500 ft, and a new species, T. echinatus, known by a sample from tropical lowland evergreen rain forest between 2700 and 3700 ft. Limnomys is monotypic and the species L. sibuanus is represented by only five examples obtained from tropical montane rain forest between 6200-7200 and 9000 ft. Among Philippine murines, the phylogenetic alliances of Tarsomys and Limnomys are with species of Tryphomys, Abditomys, Bullimus, and Rattus. These genera form one of three groups which reflect the broad outlines of a pattern of phylogenetic relationships estimated by us from a preliminary survey of primitive and derived character states among samples of native Philippine murine rodents, based primarily on study skins and skulls. Another group contains the species of Phloeomys, Crateromys, Carpomys, Batomys, Apomys, Crunomys, Archboldomys, Chrotomys, Celaenomys, and Rhynchomys. The final group holds only Anonymomys mindorensis. The relationships of Tarsomys and Limnomys to members within their group are unresolvable within the context of our study"--P. 3.Item Philippine rodents : redefinitions of known species of Batomys (Muridae, Murinae) and description of a new species from Dinagat Island. American Museum novitates ; no. 3237(New York, NY : American Museum of Natural History, 1998) Musser, Guy G.; Heaney, Lawrence R.; Tabaranza, Blas R."Batomys russatus, new species, is described and compared with the other species of Batomys. The new form is represented by three specimens collected in lowland tropical evergreen rainforests on Dinagat (10 degrees N, 125 degrees 45'E), an elongate, mountainous small island off the northwest coast of Mindanao in the Philippine Archipelago. Among diagnostic traits of the new species are its small body size, colorful russet fur, and complete (primitive) cephalic arterial patterns- in this last feature, it is unique among species of extant murines. Three other species of Batomys have been described, all of them larger-bodied animals with somber brown fur and a derived cephalic arterial circulation. All available specimens (N = 162) of these larger-bodied species were studied to reevaluate morphological and distributional species boundaries. Among the three, B. dentatus is the most distinct. Represented only by the holotype collected in the highlands of Luzon, it is the only known Batomys with a furry brown-and-white tail and exceptionally large molars, both in absolute measurements and relative to cranial size. Batomys granti also occurs in the mountains of Luzon, but it is morphologically very similar to B. salomonseni, which is now represented by samples from the islands of Mindanao, Leyte, Biliran, and Dinagat. These two species differ in tail diameter and pilosity, hind foot configuration, cranial proportions, and frequency of certain molar cusps. The new Batomys is one of 29 native mammal species currently documented from Dinagat by voucher specimens. It and another rodent, Crateromys australis, along with the insectivore Podogymnura aureospinula- approximately 10% of the mammalian fauna- have been found only on Dinagat. Other species native to the island either occur on nearby islands that were apparently joined during the late Pleistocene to form a larger land area (Greater Mindanao), or are found throughout the Philippine Archipelago and even in adjacent regions outside the Philippines. Within the Greater Mindanao cluster of islands, only Mindanao, the largest, has a proportion of endemic mammalian species comparable to that on the much smaller Dinagat; the other islands lack endemics altogether. Why this is so is unknown"--P. 2.Item Systematic mammalogy : contributions in honor of Guy G. Musser.

(American Museum novitates, no. 3802)(American Museum of Natural History., 2014-05-16) Heaney, Lawrence R.; Balete, Danilo S., 1960-; Rickart, Eric A.; Veluz, M. Josefa (Maria Josefa); Jansa, Sharon A.We describe and name three new species of Musseromys from the mountains of northern Luzon based on morphological and DNA sequence data. Previously, Musseromys was known only from one species from the lowlands of central Luzon. These are the smallest-known members of the cloud rat clade of endemic Philippine murids, weighing only 15-22 g, an order of magnitude smaller than the previously smallest known members of the clade (Carpomys spp.), and more than two orders of magnitude smaller than the largest members (Phloeomys spp.). These discoveries raise the number of native murids documented on Luzon to 43, 93% of which are endemic, and 88% of which are members of two endemic Philippine clades. Musseromys is inferred to have originated in montane habitats, probably in the Central Cordillera of northern Luzon, with movement to two other areas on Luzon, one in montane habitat and one in lowland habitat, associated with the speciation process.
