A Survey of Small Mammals from Mt.

Musser1 and Nguyen Truong Son2 1 Division of Vertebrate Zoology (Mammalogy), American Museum of Natural History, Central Park West @ 79th Street, New York, NY 10024, USA 2 Department of Zoology, Institute of Ecology and Biological Resources, 18 Hoang Quoc Viet Road, Cau Giay, Hanoi, Vietnam Abstract. A survey of small mammals from Mt. Tay Con Linh II, Ha Giang Province, Vietnam (22°45’27”N, 104°49’49”E) resulted in the capture of 17 species of bat, insectivore, and rodent: Cynopterus sphinx, Rousettus leschenaulti, Sphaerias blanfordi, Scaptonyx fusicaudus, Chodsigoa parca, Chodsigoa caovansunga new species, Blarinella griselda, Crocidura attenuata, Crocidura fuliginosa, Crocidura wuchihensis, Belomys pearsonii, Callosciurus inornatus, Leopoldamys edwardsi, Niviventer fulvescens, Niviventer langbianis, Niviventer tenaster and Chiropodomys gliroides. In addition Ratufa bicolor and Tamiops sp. are reported from observations. Scaptonyx fusicaudus and Blarinella griselda represent new distributional records for Vietnam. As part of the process of identifying specimens of Vietnamese Chodsigoa, we examined specimens of C. lamula and C. parva, including the holotype of parva and concluded that C. parva is not synonymous with C. lamula but actually represents a separate, very small species currently known only from the type locality in Yunnan, China. Key words: biodiversity, Chodsigoa, mammals, Vietnam. Vietnam’s northern frontier was once an expanse of subtropical forest but is now almost entirely converted to grassland or savanna (Wikramanayake et al. 2002). Only very small fragments of forest remain in secluded mountainous regions but these are currently under threat, and the opportunity to study their native fauna is fast disappearing (MacKinnon 1997; Wikramanayake et al. 2002). As part of an effort to document small mammal species diversity from this region we surveyed Mt. Tay Con Linh II (22°45’27”N, 104°49’49”E; Fig. 1). Subtropical forest still exists here at altitudes above approx- imately 1200 m and from our base camp at 1400 m we collected small mammals along a transect extending all the way to the summit at 2200 m. Descriptions of habitats encountered along our study transect are as follows: 1250–1550 m — Disturbed subtropical forest with an estimated canopy height of between 20–25 m. There was a lush understory of shrubs, saplings and woody lianas. Most canopy trees were about 60 cm diameter breast height (dbh) but on precipitous slopes we ob- Fig. 1.

The genus Surdisorex represents Kenya's only endemic genus of mammal. It has heretofore included two species from the highlands of central Kenya. Here we add a third species, also from Kenya, based on a specimen from the eri- caceous zone of the eastern slopes of Mt. Elgon. Although this species further aligns Mt.

The aim was to study the relationships at higher taxonomic levels within this family, and in particular the position of difficult clades such as Anourosorex and Myosorex. The data confirmed two monophyletic subfamilies, Soric- inae and Crocidurinae. In the former, the tribes Anourosoricini, Blarinini, Nectogalini, Notiosoricini, and Soricini were supported. The latter was formed by the tribes Myosoricini and Crocidurini. The genus Suncus appeared to be paraphyletic and included Sylvisorex.We further suggest a biogeographical hypothesis, which shows that North America was colonized by three independent lineages of Soricinae during middle Miocene. Our hypothesis is congruent with the first fossil records for these taxa. Using molecular dating, the first exchang- es between Africa and Eurasia occurred during the middle Miocene. The last one took place in the Late Miocene, with the dispersion of the genus Crocidura through the old world.

    Dental Anomalies in Three Species of Shrews from Indiana Thomas W. French* Department of Life Sciences Indiana State University Terre Haute, Indiana 47809 Introduction Dental anomalies in shrews are not common. Hall (1940) found no cases of miss- ing or extra teeth in 1,837 specimens of North American shrews and Jackson (1928) reported only 5 specimens (0.05%) with dental anomalies out of 10,431 Sorex and Microsorex examined. Information on dental anomalies in shrews has been best sum- marized by Choate (1968). Most reported dental anomalies result from a reduction in the number of upper, and to a lesser extent, lower unicuspid teeth (12, 13, C, P2, P3, 13, and c of Choate 1968). No case of genetically deleted molariforms or first incisors has been reported in shrews. Subnumerary dentitions have been reported from Sorex araneus (Reinwaldt 1961), S. cinereus ohionensis (Bole and Moulthrop 1942), 5. minutus (Reinwaldt 1961), S. obscurus longicauda (Jackson 1928), S. tundrensis (Pruitt 1957), Blarina brevicauda and B. b. carolinensis (= B. carolinensis) (Choate 1968), B. adamsi (from the upper Pliocene— Hibbard 1953), Cryptotis goodwini, C. mexicana, C. nigrescens, and C. parva (Choate 1970), and Microsorex hoyi (Jackson 1928). Supernumerary dental formulas have resulted most often from extra upper unicuspids and have been reported from 1 Sorex o. obscurus (Jackson 1928), 1 S. s. saussurei (Hooper 1946), 3 Blarina carolinensis (Choate 1968), 1 Crocidura cyanea, 2 C. hirta (Meester 1953), and 3 C. marquensis (Dippenaar 1978). Extra unicuspids in the lower jaw have been reported only from Blarina brevicauda (Hibbard 1953). Supernumerary molariform teeth in shrews are especially scarce.

The new species, Crocidura narcondamica sp. nov. is medium-sized and has a distinct external morphology (darker-grey dense fur with a thick and darker tail) and craniodental (braincase is rounded and elevated with weak lambdoidal ridges) characters in comparison with other close congeners. This description illuminates the rst discovery of soricid fauna (shrew) from this volcanic island and a total of 12 Crocidura species catalogued in the Indian checklist of mammals. The newly discovered species maintained sucient genetic distances (12% to 16.6%) with other Crocidura species known from the Indian mainland, Andaman and Nicobar Archipelago, and Myanmar.

  • A New Genus of Asiatic Short-Tailed Shrew (Soricidae, Eulipotyphla) Based on Molecular and Morphological Comparisons
    ZOOLOGICAL RESEARCH A new genus of Asiatic short-tailed shrew (Soricidae, Eulipotyphla) based on molecular and morphological comparisons Kai He1,2,#, Xing Chen1, Peng Chen1, Shui-Wang He1, Feng Cheng1, Xue-Long Jiang1,*, Kevin L.

Blarinelline shrews were once widely distributed throughout Keywords: Blarinellini; Capture-hybridization; Eurasia and North America, though only members Mitogenome; Molecular phylogeny; Next-generation of the Asiatic short-tailed shrew genus Blarinella sequencing; Pantherina currently persist (mostly in southwestern China and INTRODUCTION adjacent areas). Only three forms of Blarinella have Asiatic short-tailed shrews, currently classified as species in the been recognized as either species or subspecies. genus Blarinella, are small insectivorous mammals distributed However, recent molecular studies indicated a mainly in central and southwestern China, adjacent Myanmar, strikingly deep divergence within the genus, implying and northern-most Vietnam. These small- to middle-sized the existence of a distinct genus-level lineage. We shrews are uniformly black or dark brown and have large sequenced the complete mitochondrial genomes incisors, heavy tooth pigmentation, and a short tail that is typically 40%–60% of the head-body length. The fore claws are and one nuclear gene of three Asiatic short-tailed enlarged, suggesting adaptation for a semi-fossorial lifestyle and two North American shrews and analyzed (Wilson & Mittermeier, 2018).

While the most advanced technological means to photograph and reproduce this document have been used, the quality s heavily dependent upon the quality of the original submitted. The following explanation of techniques is provided to help you understand rrarkings or patterns which may appear on this reproduction. 1. The sign or "target" for pages apparently lacking from the document photographed is "Missing Page(s)". If it was possible to obtain the missing page(s) or section, they are spliced into the film along with adjacent pages. This may have necessitated cutting thru an image and duplicating adjacent pages to insure you complete continuity. 2. When an image on the film is obliterated with a large round black mark, it is an indication that the photographer suspected that the copy may have moved during exposure and thus cause a blurred image.
