Is the northern chevrotain, Tragulus williamsoni Kloss, 1916, a synonym or one of the least-documented mammal species in Asia?

Raffles Bull. Zoology 65: 506–514.

Abstract:

The northern chevrotain, Tragulus williamsoni Kloss, 1916, was described, and for nearly a century remained known, from only one specimen. This had been collected from Meh Lem in northern Thailand in 1916. Following a taxonomic revision of the genus Tragulus, its taxonomic status was regarded as uncertain. New information from a Tragulus specimen from Xishuangbanna, Yunnan province, China, stored in the Kunming Institute of Zoology, corroborates the status of T. williamsoni as a distinct taxon based on skull measurements. The conservation implications of this finding include the urgent need to determine conclusively the taxonomic status of T. williamsoni, and its distribution and conservation status.

The Identity of Mousedeer (Mammalia: Artiodactyla: Tragulidae) observed at Lower Peirce Fotest, Singapore.

NATURE IN SINGAPORE 2009 2: 467–473.

Conclusion:

The napu and the kanchil are usually distinguished from each other by the number of white stripes on their throat and
neck. However, in rare cases, this does not hold true at least for the kanchil. When coat colour and dark mid-ventral
stripe are taken into consideration, the mousedeer from Lower Peirce, thought to be a napu, Tragulus napu, should be a
kanchil, Tragulus kanchil fulviventer. Therefore, there is no recent record of wild napu on Singapore Island.

Thylacinus (Marsupialia: Thylacinidae) from the Mio-Pliocene boundary and the diversity of Late Neogene thylacinids in Australia.

PeerJ. 2015; 3: e931. Published online 2015 May 12. doi: 10.7717/peerj.931

Abstract:

Thylacinus yorkellus is described as a new, moderately small-bodied species of thylacinid from the latest Miocene or, more likely, earliest Pliocene of South Australia. The new species can be diagnosed by the autapomorphic presence a strongly developed precingulid that terminates in a cuspidule on the anterobuccal face of the paraconid of the lower molars and a tiny basal anterior cuspidule on P2, P3 and the lower molars. It is found by cladistic analysis to be the sister species of the recently extinct Th. cynocephalus and distinct from the approximately coeval Th. megiriani from the Northern Territory. New dentary material is described and referred to Th. megiriani. These add character data and allow this species to be re-diagnosed based on autapomorphic character traits. Each of the three known late Miocene to early Pliocene Thylacinus species (Th. potens, Th. megiriani and Th. yorkellus) suggest that, instead of declining, there was a modest radiation of Thylacinus in the late Miocene.

Kupferrote Springaffen (Plecturocebus cupreus)

Zeitschrift des Kölner Zoos 65(2): 49-62.

Volltext (PDF)

Zusammenfassung:

Wir berichten über Ergebnisse von Freilandstudien an Kupferroten Springaffen (Plecturocebus cupreus) an der Estación Biológica Quebrada Blanco (EBQB), einer Forschungsstation im nordöstlichen peruanischen Amazonastiefland. Diese Springaffen können aufgrund ihrer Nahrungszusammensetzung als frugivor-faunivor charakterisiert werden. Sie leben in Familiengruppen von 2-6 Mitgliedern. Die Beziehungen zwischen dem Elternpaar sind gekennzeichnet durch einen größeren Beitrag des Weibchens zur sozialen Fellpflege und zur Aufrechterhaltung der räumlichen Nähe. Männchen sind hingegen die hauptsächlichen oder einzigen Träger der Jungtiere. Nach den bisherigen genetischen Befunden sind die Kupferroten Springaffen monogam, d. h. Jungtiere stammen von Männchen eines Paares ab, Vaterschaften außerhalb des Paares wurden nicht gefunden. Außerdem übernehmen sie bei Begegnungen mit potentiellen Raubfeinden und mit Nachbargruppen aktiver als die Weibchen. Springaffen zeigen eine ungewöhnliche Assoziation mit Mistkäfern. Wir enden mit einem Ausblick auf offene Fragestellungen.

Fukomys mechowii (Rodentia: Bathyergidae).

Mammalian Species 53 (1011): 145-159. https://doi.org/10.1093/mspecies/seab014

Abstract:

Fukomys mechowii (Peters, 1881), the giant mole-rat or Mechow’s mole-rat, is a cooperatively breeding, tooth-digging, subterranean rodent. It is the largest representative of the genus Fukomys, which is part of the African mole-rat family Bathyergidae. It is found in mesic shrubland, savannah habitats, and agricultural lands in central Africa, its range extending through Angola, the Democratic Republic of Congo, and Zambia. Fukomys mechowii is hunted for its meat in rural areas but its population is considered to be stable. It is rarely housed in captivity and is listed as “Least Concern” (LC) on the International Union for Conservation of Nature Red List of Threatened Species.

Notes on the Sika Deer.

Journal of Mammalogy 37 (1): 99-105.

Extract:

When two men undertake so large a task as compiling a checklist of palae-arctic and Indian mammals, they cannot fairly be expected to escape some oversights. Such seem to have occurred in J. R. Ellerman's and T. C. S. Morrison-Scott's treatment of the sika deer.

First, they list Sika dugenneanus (sic) as a synonym, with “no locality,” for the South China Sika, Cervus nippon kopschi Swinhoe, 1873. Alike in their spelling of “dugenneanus” in making it a synonym for kopschi, and in declaring it had no locality, they seem to follow the statement of Allen (1940), but on all three points Allen would appear to mislead them.

The name dugennianus was coined by the French missionary, Father P. M. Heude, who gathered a large collection of mammals at the Sikawei Museum in Shanghai, and created infinite confusion among Chinese fauna by proliferating synonyms with an almost...

Gibbon Systematics and Species Identification.

International Zoo News 42(8): 467-501.

Abstract:

A study of wild and captive gibbons and museum specimens, and a survey of the literature suggests that gibbons (genus Hylobates) include at least 11, possibly 12 species, which form 4 distinct groups (subgenera Hylobates, Bunopithecus, Nomascus, and Symphalangus): These are the 44-chromosome gibbons (including the Hylobates lar group and H. klossii: 5 species); the hoolock ( H. hoolock, 1 species); the H. concolor group (3, possibly 4 species); and the siamang ( H. syndactylus, 1 species). A key for the identification of adult gibbons based on visual characteristics is presented, together with colour photographs and distribution maps of all recognised species (11). In addition, diagnostic vocal characteristics of all species are described and illustrated with sonagrams.

Mixed herds of Common and Defassa waterbuck, Kobus ellipsiprymnus (Artiodactyla: Bovidae), in northern Kenya.

Bonn. zool. Beitr. 37(3): 183-193.

Summary:

Observations of two mixed herds of Common and Defassa Waterhuck with potential hybrids of the two forms in Buffalo Springs Game Reserve, northern Kenya, are reported. Current theories published in the literature as to the distributional history and taxonomic status of the two forms are discussed.

Zusammenfassung:

Die Beobachtung von 2 gemischten Herden mit Ellipsen- und Defassa-Wasserböcken und möglichen Hybriden zwischen beiden Formen in Buffalo Springs Game Reserve, N-Kenia, ist Anlaß für eine Diskussion der in der Literatur publizierten Vorstellungen zu ihrer Verbreitungsgeschichte und zu ihrem taxonomischen Status.
