[Mammalogy • 2017] Uromys vika • A New Species of Giant Rat (Muridae, Uromys) from Vangunu, Solomon Islands ---ScRaBBlE


Uromys vika Lavery & Judge, 2017

Abstract
We describe the first new rodent species from Solomon Islands in more than 80 years. This new giant rat is known from a single specimen captured in a commercially felled Dillenia salomonensis tree on Vangunu Island. Morphologically, it closely resembles a fascinating secondary radiation of 3 species of Uromys (Cyromys) that are endemic to Guadalcanal Island. The cranium can be readily distinguished from those of other species of Uromys by its shorter maxillary tooth row, and shorter incisive foramina. The existence of this species has been suspected for over 2 decades. It is rare and cryptic, and conservation status is Critically Endangered due to its small distributional range, apparent low population densities, and rapid progress of commercial logging on Vangunu Island. Further surveys to locate additional animals and support for community led conservation initiatives on Vangunu are urgently needed to safeguard the species.

[Mammalogy • 2017] Hapalomys suntsovi • A New Species of Marmoset Rat, Hapalomys (Rodentia: Muridae), from Binh Phuoc Province, southern Vietnam; New Insights Into the Taxonomy of the Marmoset Rats Hapalomys ---ScRaBBlE


Hapalomys suntsovi  Abramov,  Balakirev & Rozhnov, 2017 

Fig. 4. General appearance of Hapalomys suntsovi based on a specimen ZIN 99484, collected from the Bu Gia Map NP, Vietnam, on 12 January 2010.

Abstract
 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 morphology, the diversity of COI gene sequences and karyotypic peculiarities. A comparison with the two currently recognised Hapalomys species is provided. This finding represents the southernmost record of marmoset rats in Vietnam.

Key words. rodents, skull morphology, genetic diversity, Southeast Asia, new species

Hapalomys suntsovi  Abramov,  Balakirev & Rozhnov, 2017

Diagnosis. A medium-sized Hapalomys that on the average is smaller in its external and cranial measurements than H. longicaudatus. It is comparable to H. delacouri in its body and cranium size, but can be distinguished by the longer tail, the relatively short incisive foramina, and the cytochrome oxidase c subunit I (COI). Distinguished from both known species by the karyotype composition.

Etymology. The new species is dedicated to Dr Viktor V. Suntsov (A.N. Severtsov Institute of Ecology and Evolution, Russian Academy of Sciences, Moscow), in recognition of his many contributions to the study of rodents of Vietnam. During 1992–2010, Dr Suntsov headed the Southern Division of the Joint Russian-Vietnamese Tropical Research and Technological Centre in Ho Chi Minh City.

Distribution. Currently known from the type locality, the Bu Gia Map National Park, Binh Phuoc Province, Southern Vietnam. It is likely to occur in the adjacent forest regions of Eastern Cambodia.


Natural history. The series of type specimens was collected in old, mature, thick trunk bamboo thickets growing along a forest road (Abramov et al., 2011). All specimens were taken by traps set 5–7 m over the ground surface. Two females caught on 13 January 2010 were pregnant (at early stage) bearing four and five small embryos.

[Mammalogy • 2018] Systematics, Distribution and Ecological Analysis of Rodents in Jordan ---ScRaBBlE


Acomys russatus lewisi  Atallah, 1967

in Amr, Abu Baker, Qumsiyeh & Eid, 2018.

Abstract

Distributional and ecological data were given to all rodents of Jordan. The rodent fauna of Jordan consists of 28 species with 20 genera in eight families (Cricetidae, Dipodidae, Gliridae, Hystricidae, Muridae, Myocastoridae, Sciuridae,and Spalacidae), including four introduced species.Keys for families and species were provided, along with diagnosis for each species and cranial illustrations for most species. Habitat preference and zoogeographic affinities of rodents in Jordan were analyzed, as well as their status and conservation.Threat categories and causes of threats on the rodents of Jordan were also analyzed.

        The distribution of rodents in Jordan represents a reflection of their global distribution ranges and habitat preferences. Species associated with the temperate forest of northern Jordan includes Sciurus anomalus and two wood mice, Apodemus mystacinus and A. flavicollis, while non-forested areas are represented by Nannospalax ehrenbergi and Microtus guentheri. Strict sand dwellers include Gerbillus cheesmani and G. gerbillus. Petrophiles associated with sandstone or black lava deserts are exemplified by Acomys russatus, A. r. lewsi, H. indica and S. calurus. Others including: Jaculus jaculus, G. nanus, G. henleyi, Meriones crassus, and M. libycus are all desert-adapted species with wider ranges of distribution where scarce vegetation, wadibeds, and marabs with clay, loess, or gravel surfaces provide foraging grounds and shelter. A single species, Gerbillus dasyurus, exhibits a wide range of distribution over diverse habitat types.

        The rodent fauna of Jordan consists of assemblages of different zoogeographical affinities. Nine, three, and seven were restricted or had most of its range within the Mediterranean, Irano-Turanian, and Saharo Arabian, respectively. Sciurus anomalus, Apodemus sp., Nannospalax ehrenbergi, and Microtus guentheri reached their most southern range of distribution in the Mediterranean regions of Jordan. The distribution of Gerbillus cheesmani extends from Asian deserts in India westwards into the Arabian Peninsula crossing Jordan as its most western range of distribution. Typical rodents of Saharo-Arabian affinities are represented by desert jerboas, gerbils, and jirds. North African species such as G. andersoni, G. gerbillus reached their most eastern distribution in southern Jordan. Both G. henleyi and G. nanus are widely-distributed species across North Africa reaching as far as India to the east, representing most northern outpost for these two species. Sekeetamys calurus is a nearly endemic to the Eastern Mediterranean region within southern Jordan and Sinai. Relicts are represented by Eliomys melanurus and Acomys russatus lewisi.

        Several threats affecting the rodent biodiversity in Jordan were identified including habitat loss and degradation, human disturbance and related activity, legislative and public awareness. The global conservation status of the rodents of Jordan according to the IUCN Red List include 22 species as least concern, one as near threatened (Allactaga euphratica), and one as data deficient (Nannospalax ehrenbergi). According to the regional assessment, one species is critically endangered, three species are considered endangered, one vulnerable.

[Mammalogy • 2018] Halmaheramys wallacei • A New Species of Halmaheramys (Rodentia: Muridae) from Bisa and Obi Islands (North Maluku Province, Indonesia) ---ScRaBBlE


Halmaheramys wallacei
Fabre, Reeve, Fitriana, Aplin & Helgen, 2018


Abstract
We describe a new species of murine rodent from a skull collected on Bisa Island and 3 specimens from Obi Island, North Maluku Province, Indonesia. Molecular and morphological data indicate a close relationship with Halmaheramys bokimekot (Fabre et al. 2013). The new species is characterized by its combination of large size; short tail with large scales; spiny, coarse, dark dorsal pelage with long black guard hairs; and a dark gray ventral pelage that contrasts slightly with the dorsum. The Bisa specimen displays unusual zygomatic arch morphology, which may be a disease-related deformity, or potentially a sexually dimorphic trait. The new species shares several external and cranio-mandibular features with its sister species from Halmahera that differ from those of Rattus species, including a spiny pelt, deep palatine sulci, a high rostrum and relatively flat dorsal profile, short incisive foramina, short palatal bridge, and molars with simple occlusal patterns. Although certain morphological characteristics of the new taxon suggest an affinity with the taxonomically diverse and geographically widespread Rattus, in other respects it clearly fits into the Wallacean clade containing Bunomys, Paruromys, and Taeromys, as indicated by molecular phylogenetic analyses. Along with the recent discovery of Halmaheramys, recognition of this new species from Bisa and Obi Islands underscores the north Moluccan region’s high endemism, conservation importance, and the urgent need for a better inventory of its biodiversity.

Key words: anatomy, biogeography, Moluccas, Murinae, Rattus division, taxonomy, Wallacea

Etymology.— The new species name honors the naturalist Alfred R. Wallace, who spent more than 10 years in the Malay Archipelago, and passed by Obi in difficult sailing. The presence of this rat in the Moluccas supports the concept of the Wallacea zoogeographic pattern for rodents, highlighting the mixed Asian and Australo-Papuan origins of murines in the region (see discussion on biogeography).

Vernacular names.— We suggest common names for this species both in English, “Wallace’s large spiny rat”, and in Bahasa Indonesia as “tikus-duri besar Wallace.”

Kami mendeskripsikan tikus jenis baru berdasarkan satu spesimen tengkorak yang dikoleksi dari Pulau Bisa dan 3 spesimen dari Pulau Obi, Propinsi Maluku Utara, Indonesia. Data molekuler dan morfologi menunjukkan adanya hubungan yang erat dengan Halmaheramys bokimekot (Fabre et al. 2013). Jenis baru ini dicirikan dengan kombinasi berbagai karakter yaitu ukuran tubuh besar; ekor pendek dengan sisik besar; rambut kasar, berduri, di bagian dorsal berwarna gelap dengan rambut-rambut penjaga panjang berwarna hitam; dan rambut di bagian ventral berwarna abu-abu tua, sedikit kontras dengan bagian dorsal. Pada “zygomatic arch” spesimen tengkorak dari Pulau Bisa terlihat berbeda, hal ini mungkin merupakan kelainan bentuk akibat penyakit atau berpotensi sebagai ciri seksual dimorfisme. Jenis baru ini memiliki beberapa ciri eksternal dan cranio-mandibular yang mirip dengan spesies sejenisnya dari Halmahera yang diketahui berbeda dari jenis-jenis Rattus antara lain kulit tertutup rambut berduri, sulkus palatum dalam, rostrum tinggi dengan profil datar di bagian dorsal, foramen incisifum pendek, rigi palatum pendek, dan pola oklusi sederhana pada gigi geraham. Meskipun karakteristik morfologi tertentu dari jenis baru ini menunjukkan kemungkinan afinitas dengan genus Rattus yang secara geografi jenisnya beragam dan terdistribusi luas, namun berdasarkan hasil analisa filogenetik molekuler, spesies baru ini jelas berada dalam satu klade dengan klaster Wallacean yang terdiri dari Bunomys, Paruromys, dan Taeromys. Seiring dengan penemuan Halmaheramys baru-baru ini, pengenalan spesies baru dari Kepulauan Bisa dan Obi menggarisbawahi tingginya endemisitas dan pentingnya konservasi di Maluku Utara, serta urgensi inventarisasi keanekaragaman hayati yang lebih baik.
