D. E.; Fleagle, John G.; Musser, Guy G.; Holden, Mary Ellen.; Voss, Robert S.; Myers, Philip. ItemCrunomys and the small-bodied shrew rats native to the Philippine Islands and Sulawesi (Celebes). Bulletin of the AMNH ; v. 174, article 1([New York] : American Museum of Natural History, 1982) Musser, Guy G."Crunomys contains four species native to the Philippine Islands and Sulawesi (Celebes). Crunomys fallax is from Luzon; C. rabori, new species, occurs on Leyte; C. melanius lives on Mindanao; and C. celebensis, new species, is native to middle altitudes in mountainous Central Sulawesi. The species are described and contrasted with one another. Crunomys is related to Archboldomys, new genus and species, a small-bodied shrew rat from southeastern Luzon. That rat is described, compared with species of Crunomys, then contrasted with the three species of small-bodied shrew rats endemic to Central Sulawesi: Melasmothrix naso, Tateomys rhinogradoides, and T. macrocercus, new species. Relationships among the four genera are discussed. Insular and altitudidinal distributions are also presented as well as some data on habitats and habits"--P. 3. ItemThe definition of Apomys, a native rat of the Philippine Islands. American Museum novitates ; no. 2746(New York, N.Y. : American Museum of Natural History, 1982) Musser, Guy G."Apomys Mearns (1905) contains eight species native to the backbone of the islands in the Philippine archipelago. The genus was recognized for more than 40 years after it was described, then merged with Rattus, and later reinstated as distinct from Rattus. Throughout this period, the morphological boundaries of the group remained vague, the diagnosis nonexistent, and the contents nebulous. Apomys is defined here, the species in it are discussed, and the contrasts between it and Rattus are outlined"--P. . ItemDefinitions of Indochinese Rattus losea and a new species from Vietnam. American Museum novitates ; no. 2814(New York, N.Y. : American Museum of Natural History, 1985) Musser, Guy G.; Newcomb, Cameron."The morphological characteristics, geographic distribution, habitat, and habits of Rattus losea are presented. The species occurs in grass, scrub, and agricultural habitats of Indochina north of the Isthmus of Kra (lat. 1050'N). Its closest phylogenetic relative is the new species, Rattus osgoodi, known from samples obtained from the Langbian Peak region in southern Vietnam. The morphological and geographic features of R. losea and its relative are contrasted with those of other Indochinese Rattus, namely, R. rattus, R. norvegicus, R. exulans, R. sikkimensis, R. nitidus, R. turkestanicus, R. argentiventer, and R. brunneus. The ricefield rat, R. argentiventer, may be more closely related to R. losea and the new species than to any other species of Indochinese Rattus, a hypothesis that should be tested with other kinds of data. Results presented here are part of a systematic study of native Asian Rattus"--P. . ItemDescription of a new genus and species of rodent (Murinae, Muridae, Rodentia) from the Khammouan Limestone National Biodiversity Conservation Area in Lao PDR. American Museum novitates ; no. 3497(New York, NY : American Museum of Natural History, 2005) Musser, Guy G.; Smith, Angela L.; Robinson, M. F. (Mark Francis); Lunde, Darrin P.Saxatilomys paulinae, a new genus and species of murid rodent in the Dacnomys division is described. It is based on two whole specimens and 14 individuals represented by fragments recovered from owl pellets. The samples come from the Khammouan Limestone National Biodiversity Conservation Area in Khammouan Province in central Lao PDR. This tower karst landscape is part of the Quy Dat limestone massif, which extends eastward into north-central Vietnam (Binh Tri Thien Province). The new genus and species is morphologically (and probably phylogenetically) allied to species of Niviventer and Chiromyscus, which are also members of the Dacnomys division, but its semispinous dark gray upperparts, dark frosted gray underparts, large, extremely bulbous footpads, and a combination of derived and primitive cranial and dental traits exclude it from membership in Niviventer, Chiromyscus, or any other described genus of Indo-Malayan murid. The new species is likely petricolous, and is part of a small but unique community of small nonvolant mammals containing the petricolous gymnure, Hylomys megalotis, and hystricognath, Laonastes aenigmamus. All three species have been collected only in forested, rocky habitats of the Khammouan Limestone, but comparable environments in the adjacent Vietnamese portion of the Quy Dat limestone massif may harbor these same species specialized for living in forested, karstic landscapes. ItemDescription of a new genus and species of rodent (Murinae, Muridae, Rodentia) from the tower karst region of northeastern Vietnam ; American Museum novitates : no. 3517(New York, NY : American Museum of Natural History, 2006) Musser, Guy G.; Lunde, Darrin P.; Nguỹên, Trừơng Sơn.Tonkinomys daovantieni, a new genus and species of murid rodent in the Dacnomys division, is described. It is represented by 14 adults collected from talus habitats in the forested tower karst landscape of the Huu Lien Nature Reserve of northeastern Vietnam. The combination of semispinous, dense, grayish black fur covering upperparts; a dark gray venter; gray ears; a thick, bicolored tail considerably shorter than length of head and body; and large, extremely bulbous footpads is unlike any other species of Indomalayan murid. Body size and build of the new rat, along with some cranial features, are similar to the Thai Leopoldamys neilli, but other cranial traits coupled with molar occlusal patterns resemble morphology in species of the Indomalayan Niviventer, Chiromyscus, and Saxatilomys. The new species is petricolous, includes insects in its diet, and was found only in talus composed of large limestone blocks. Its distribution in the reserve is likely patchy. Whether this limestone rat is restricted to the extensive karst regions of northeastern Vietnam or also occurs in southern China and elsewhere in the northern karst landscapes of Indochina, and Vietnam in particular, will be known only by conducting surveys in limestone regions outside of northeastern Vietnam. ItemEpimys benguetensis, a composite, and one zoogeographic view of rat and mouse faunas in the Philippines and Celebes. American Museum novitates ; no. 2624(New York, N.Y. : American Museum of Natural History, 1977) Musser, Guy G."I record here that the name Epimys benguetensis is based on a composite holotype: the skin is an example of Rattus rattus mindanensis and the skull is from R. nitidus. I also discuss a dichotomy between endemic and commensal murid rodents on the Philippine Islands and Celebes. Each area has its unique assemblage of endemic species of rats and mice; these are mostly restricted to primary forest. Each area shares a commensal fauna composed of Rattus rattus, R. exulans, R. argentiventer, R. norvegicus, R. nitidus, and Mus musculus. These animals live in habitats made and maintained by humans. Such a faunal dichotomy occurs wherever there is an endemic fauna and wherever humans have settled throughout the Indonesian Archipelago east of Wallace's Line"--P. . ItemThe giant rat of Flores and its relatives east of Borneo and Bali. Bulletin of the AMNH ; v. 169, article 2(New York : American Museum of Natural History, 1981) Musser, Guy G."Five murids are known only from Flores: Papagomys armandvillei; P. theodorverhoeveni, new species; Hooijeromys nusatenggara, new genus and species; Floresomys naso, new genus and species; and Spelaeomys florensis. One kind, Komodomys rintjanus, occurs on Flores as well as the Komodo Islands of Rintja and Padar. Papagomys armandvillei still lives on Flores and is also represented by subfossil specimens; P. theodorverhoeveni, F. naso, S. florensis, and K. rintjanus are known by subfossil fragments, the last still lives on the Komodo Islands; and Hooijeromys is based on specimens from sediments thought to be Pleistocene. Characteristics of the species are described. The morphological diversity among them indicates adaptations to different habitats and habits, as well as a bipartite arrangement of phylogenetic affinities. Spelaeomys may be part of a group that includes the genera native to New Guinea. Papagomys clusters with Hooijeromys, Komodomys, and probably Floresomys to form a separate assemblage that has its affinities with Eropeplus and Lenomys on Sulawesi. The postulated relationships of the Floresian rats is set in a framework of possible paleogeographic reconstructions in the Indo-Australian region. The native murids are also contrasted with the rest of the mammalian fauna now known to occur on Flores"--P. 71. ItemHigh resolution images for 'A systematic review of Sulawesi Bunomys (Muridae, Murinae) with the description of two new species.

American Museum novitates ; no. 3110(New York, N.Y. : American Museum of Natural History, 1994) Musser, Guy G.; Brothers, Eric M. ItemIdentities of rats from Pulau Maratua and other islands off East Borneo. American Museum novitates ; no. 2726(New York, N.Y. : American Museum of Natural History, 1982) Musser, Guy G.; Califia, Debra."Rats from Pulau Maratua and from off the east coast of Borneo beyond the 100 fathom line were originally identified as Epimys mara and E. tua (Miller, 1913). Subsequent reports on the original series have allied the taxa with Rattus muelleri (Chasen, 1940) and house rats, R. rattus (Chasen, 1940; Medway, 1965, 1977; Schwarz and Schwarz, 1967). Actually, two species live on the island, R. rattus diardii and R. tiomanicus mara (tua is a synonym). We explain our identifications in the context of discussion and questions about R. rattus diardii and especially R. tiomanicus in the Malayan region"--P. . ItemThe identity of Tarsius pumilus, a pygmy species endemic to the montane mossy forests of central Sulawesi. American Museum novitates ; no. 2867(New York, N.Y. : American Museum of Natural History, 1987) Musser, Guy G.; Dagosto, Marian.; Raven, Henry Cushier, 1889-1944."In 1917, Henry C. Raven obtained a small-bodied tarsier from upper montane rain forest in the mountains of Central Sulawesi. Miller and Hollister (1921b) designated the specimen as holotype of Tarsius pumilus, included two others collected from lowland evergreen rain forest, and pointed to small body size as one of the diagnostic specific characters. Subsequent faunal checklists and taxonomic revisions treated pumilus as a subspecies of the widespread Sulawesian Tarsius spectrum until 1985 when Niemitz advocated recognition of specific status for pumilus based upon the original series and recorded vocalizations. But only one of the three specimens discussed by Miller and Hollister is an example of T. pumilus, and the calls said to be those of this species were probably made by T. spectrum. Tarsius pumilus is distinctive, but it is known by only the holotype and a second example from montane forest in Central Sulawesi. The morphological and biogeographical limits of the species based upon these two specimens are documented here. The definition of T. pumilus is set within a context of morphological and geographical comparisons among T. bancanus (Sunda Shelf), T. syrichta (southern Philippine islands), and T. spectrum (Sulawesi and nearby islands); and subsequent comparisons between these three and T. pumilus. Information is provided on habitat and faunal associations of T. pumilus. The species is also contrasted in greater detail with morphology, habitats, and regional as well as altitudinal distributions of T. spectrum. A hypothesis of phylogenetic relationships among the four species of tarsiers is briefly discussed"--P. . ItemIdentity of the type-specimens of Sciurus aureogaster F. Cuvier and Sciurus nigrescens Bennett (Mammalia, Sciuridae). American Museum novitates ; no. 2438(New York, N.Y. : American Museum of Natural History, 1970) Musser, Guy G. ItemMalaysian murids and the giant rat of Sumatra. Bulletin of the AMNH ; v. 174, article 4([New York] : American Museum of Natural History, 1983) Musser, Guy G.; Newcomb, Cameron."We define the morphological boundaries and elucidate the contents of three Indo-Malayan murid genera: Palawanomys, new genus, known only from Palawan Island; Berylmys, primarily Indochinese in geographic distribution with a representative on the Sunda Shelf; and Sundamys, new genus, containing the giant rat of Sumatra and indigenous to the Sunda Shelf. We contrast the characteristics of these three genera with 11 others that have native species on the Sunda Shelf. Five of the Sundanese (or Malaysian) genera are endemic to the Shelf: Pithecheir, Kadarsanomys, Lenothrix, Palawanomys, and Sundamys. Maxomys, Haeromys, and Chiropodomys are basically Sundaic in that most of the species in each genus are endemic to the Shelf. Most of the species in the genera (Berylmys, Niviventer, Mus, and Rattus) occur outside of the Sunda region. Leopoldamys and Hapalomys are the only two which have an equal number of species in both Indochina and on the Sunda Shelf. We estimate there to be 40 native species of rats and mice on the peninsula and islands of the Sunda Shelf and 10 others whose distributions on the Shelf probably reflect introductions by human agency. Our view of the species and generic diversity of Malaysian murids, in which Rattus is a minor part, is contrasted with that of former workers who looked upon Rattus as a major component of the Sundaic murid fauna. We analyze the distributions of primitive and derived traits among the 14 native genera and examine possible phylogenetic relationships among them. Patterns formed by these alliances as well as by geographic distributions of the genera are described; questions are posed that will require answers from additional study"--P. 329. ItemMammal holotypes in the American Museum of Natural History : the lectotype of Prionailurus bengalensis alleni Sody (1949). American Museum novitates ; ; no. 2973.(New York, N.Y. : American Museum of Natural History, 1990) Lawrence, Marie A.; Musser, Guy G.; American Museum of Natural History. ItemMorphological and geographic definitions of the Sulawesian shrew rats Echiothrix leucura and E. centrosa (Muridae, Murinae), and description of a new species of sucking louse (Phthiraptera, Anoplura). (Bulletin of the American Museum of Natural History, no. 391)(American Museum of Natural History., 2014-07-25) Musser, Guy G.; Durden, Lance A.Among the 15 known genera of murine rodents endemic to the island of Sulawesi, is the shrew rat genus Echiothrix. Physically large (length of head and body = 182-235 mm; weight = 215-310 g) with a bicolored tail typically longer than head and body (100%-135% of head and body length), elongate hind feet (48-55 mm), large ears (31-35 mm), long and thin muzzle, spinous fur, and tiny molars relative to size of skull (length of molar row = 12%-13% of occipitonasal length), Echiothrix was named and described in 1867 and through the years has been treated as monotypic or containing up to three species. Results from analyses of morphometric traits derived primarily from cranial and dental measurements document the presence of two species. Echiothrix leucura (Gray, 1867) is restricted to the northern peninsular mainland east of the Gorontalo region (00°31ʹ N, 123° 03ʹ E). This distribution is concordant with that of four other murids endemic to the northeastern tip of the northern peninsula: Bunomys fratrorum, Taeromys taerae, Rattus xanthurus, and R. marmosurus. Echiothrix centrosa Miller and Hollister, 1921 (Echiothix brevicula Miller and Hollister, 1921, is a synonym), is documented by specimens from the northern peninsula west of the Gorontalo region and in the central portion of the island; 19 other murine species are also known only from the core of Sulawesi. Whether the range of E. centrosa extends to the eastern, southeastern, and southwestern peninsulas is at present unknown. Echiothrix leucura has a more elongate skull compared with E. centrosa (greater lengths of skull, rostrum, diastema, and bony palate), a wider interorbital region, larger braincase, narrower bony palate and mesopterygoid fossa, shorter incisive foramina, and appreciably larger molars; the two species also differ in frequencies of particular molar cusps and cusplets. Both species of Echiothrix are nocturnal, terrestrial, and occupy habitats in tropical lowland evergreen rain forest. Natural history observations made in the field for Echiothrix centrosa show it to be primarily vermivorous; other natural history observations derived from field work in central Sulawesi are provided. One aspect of that natural history is the ectoparasitic load borne by E. centrosa. This shrew rat is host to at least four species of ticks (Haemaphysalis kadarsani, Haemaphysalis hystricis, Haemaphysalis sp. and Amblyomma sp.), a tiny fur mite (Listrophoroides echiothrix), mesostigmatid mites belonging to the genus Laelaps, currently undetermined chiggers, a flea (Farhangia quattuordecimdentata), and a new species of sucking louse described herein as Polyplax beaucournui. This louse has tibiotarsal claws adapted for grasping slender soft hairs in the pelage and not the wide host spines; female lice also attach their eggs only to these slender hairs. The closest relative of Echiothrix is probably Paucidentomys vermidax, another Sulawesian endemic shrew rat that is also vermivorous but lacks molars and has been collected only in montane forests. The present report documents morphological and distributional limits of species in Echiothrix, places one of those species in an ecological and parasitological landscape, and generally contributes to knowledge covering endemic murid species diversity and identifying unique zoogeographical areas on Sulawesi. ItemMusser's Sulawesi Expedition specimen lists.(1973) Musser, Guy G.; Musser Field trips to Indonesia (1973-1976); American Museum of Natural History.; American Museum of Natural History. Department of Mammalogy. Archbold Expeditions Collection.Variety of specimen lists, work sheets from Musser's field work in Indonesia (Sulawesi). These include specimen gathering information such as name, number, sex, location and notes as well as packing carton inventories. Guy Musser was the Archbold Curator at the American Museum of Natural History, particularly specializing in rodents. He staged a series of expeditionary trips to Indonesia between 1973 and 1976, partially funded by the Archbold Expeditions and the Celebes Fund.

American Museum novitates ; no. 2730(New York, N.Y. : American Museum of Natural History, 1982) Musser, Guy G."The taxon latidens Sanborn, 1952, originally named and described as a species of Rattus, is taken out of that genus and placed in Abditomys, new genus. Some of its distinctive features, such as nails instead of claws on the halluces, wide upper incisors, and large molars with simple and laminar-like occlusal surfaces are not characteristic of Rattus. The species is known by two specimens from the island of Luzon in the Philippines. The relationship of latidens to other Murinae with nails on the halluces is discussed. Aspects of its natural history are presented"--P. .
