The porcupine Hystrix refossa Gervais, 1852 from the Plio-Pleistocene of Europe, with notes on other fossil and extant species of the genus Hystrix
Provedor de dados: 16
Autores: Weers, D.J. van.
Fossil Hystrix material from a large number of localities is biometrically analysed and compared with the extant species. H. major, H. etrusca, H. makapensis, and H. angressi are shown to be junior synonyms of H. refossa. H. bessarabica and H. trofimovi are shown to be junior synonyms of H. primigenia, and H. schaubi and H. cristata minor of H. vinogradovi. The dental characteristics of H. refossa, H. primigenia and H. vinogradovi are discussed.

Provedor de dados: 16
Autores: Weers, D.J. van.
The Pleistocene Hystrix vanbreei from Sangiran, Java, and Hystrix lagrelli from the Pleistocene of Henan, China are synonymized. The phylogenetic relationship of H. lagrelli with the subgenera Thecurus, Acanthion and Hystrix s.s. is discussed.

Biometric analysis and taxonomic allocation of Pleistocene Hystrix specimens (Rodentia, Porcupines) from China
Provedor de dados: 16
Autores: Weers, D.J. van; Shaohua, Zheng.
Early to Middle Pleistocene Hystrix material in the collections of the IVPP in Beijing, has been biometrically studied and compared with other fossil and extant species. The specimens are from Zhoukoudian (Beijing), the Liucheng Gigantopithecus cave (Guangxi) and other caves in that province, the Wazhuwan and Yanhui Cave (Guizhou) and from Longgupo (Sichuan). None of the fossil specimens can be allocated to the extant Chinese Hystrix brachyura subcristata Swinhoe, 1870, subgenus Acanthion F. Cuvier, 1823. Most of the collections studied consist of a mixture of two species with overlapping size ranges. Cheek teeth of most Hystrix species do not show diagnostic characters other than size, so not every one of them can be assigned with certainty to the larger...

A taxonomic revision of the Pleistocene Hystrix (Hystricidae, Rodentia) from Eurasia with notes on the evolution of the family
Provedor de dados: 16
Autores: Weers, D.J. van.
Measurements of many hundreds of the high-crowned cheek teeth of Hystrix specimens from the Euro-Asiatic Pleistocene in the collections of European and Asiatic institutions have been compared with extant species for a revision of the genus. A review is given about the extant genera and species of the family. The number of recognisable Euro-Asiatic species in the fossil record is reduced from eight to five. The European H. (A.) vinogradovi Argyropulo, 1941 is here considered to be a synonym of H. (A.) brachyura Linnaeus, 1758, and the three Asiatic species H. (H.) crassidens Lydekker, 1886, H. (H.) gigantea Van Weers, 1985 and H. (H.) magna Pei, 1987 are synonymized with H. (H.) refossa Gervais, 1852. Most of the Chinese fossil specimens are properly...

Notes on Southeast Asian Porcupines (Hystricidae, Rodentia) I. On the taxonomy of the genus Trichys Günther, 1877
Provedor de dados: 16
Autores: Weers, D.J. van.
Porcupines of the genus Trichys occur in Malaya, Sumatra and Borneo. In the present paper the confused nomenclatorial history is described and arguments are put forward to show that Hystrix fasciculata Shaw, 1801 (Malay Peninsula) is referable to Trichys Günther, 1877, and not to Atherurus F. Cuvier, 1829. In the interest of stability of nomenclature, a neotype of Trichys fasciculata (Shaw, 1801) is designated. The evidence presented demonstrates that, on the basis of the scarce material available now, the three populations must be considered one species without subspecific division.

The porcupine Hystrix (Acanthion) brachyura punungensis subsp.
Provedor de dados: 16
Autores: Weers, D.J. van.
A large number of isolated cheek teeth and a mandibular fragment of porcupines from the Late Pleistocene fissure deposits near Punung, Java, are compared with extant H. (Acanthion) brachyura Linnaeus, 1758 (southeast Asia) and H. (Acanthion) javanica (F. Cuvier, 1823) (Java). Middle Pleistocene and Holocene specimens from Java are compared with the latter species. The Punung specimens belong to one species and are considered a new subspecies, Hystrix brachyura punungensis subsp. nov. The Middle Pleistocene specimens are allocated to Hystrix brachyura subsp. and those from the Holocene to Hystrix javanica.

The porcupine Hystrix brachyura Linnaeus, 1758 in the cave deposits of Longgupo, China
Provedor de dados: 16
Autores: Weers, D.J. van.
One mandibular fragment and 10 isolated cheek teeth of a moderately sized porcupine from the well-known site Longgupo in China are described. These are the first fossil finds in China, which may be allocated to Hystrix brachyura. They have a late Pliocene to earliest Pleistocene age, representing the oldest fossil high-crowned porcupine species in China.

Comparison of Neogene low-crowned Hystrix species (Mammalia, Porcupines, Rodentia) from Europe, West and Southeast Asia
Provedor de dados: 16
Autores: Weers, D.J. van.
The low-crowned Hystrix species known of the Neogene from Europe and Asia and some new finds from Shihuiba near Lufeng, South China, are compared on the basis of numerical data. The taxonomical allocation of the seven species recognised thus far is maintained. The occurrences of two coeval Eurasian late Turolian species is discussed. The material from Lufeng is described and allocated to Hystrix primigenia (Wagner, 1848), implicating an area of distribution of this species from S.E. Europe to S.E. Asia in the Turolian. In the northern Chinese Hystricidae the increase of the cheek tooth height is more advanced than in the the West Asiatic and European representatives. The difference in ecological environment of Hystrix gansuensis Wang &amp; Qiu, 2002 (North...

Dimensions and occlusal patterns in molars of Hystrix brachyura Linnaeus, 1758 (Mammalia, Rodentia) in a system of wear categories
Provedor de dados: 16
Autores: Weers, D.J. van.
Molars of 35 skulls of Hystrix brachyura brachyura Linnaeus, 1758 have been studied. Problems with the currently used dental nomenclature are discussed. A positional, numerical system for the indication of occlusal elements, and a system of wear classes for all the different occlusal patterns are presented. Dimensions of the teeth in relation to wear are given, the variation in the occlusal patterns is described and their changes with progressive wear are discussed.

Notes on Southeast Asian Porcupines (Hystricidae, Rodentia) II. On the taxonomy of the genus Atherurus F. Cuvier, 1829
Provedor de dados: 16
Autores: Weers, D.J. van.
The individual and geographical variation of the Brush-tailed Porcupine, Atherurus F. Cuvier, 1829 from eastern India, Burma, Thailand, Laos, China, Hainan, Peninsular Malaysia and some adjacent islands has been studied from material in European and American museums. Information about this material is presented and the status of ten specific and subspecific names is discussed. Only one species, Atherurus macrourus (Linnaeus, 1758) is recognized and insufficient arguments were found for the distinction of subspecies on the basis of the small samples at present available. An error in Van Weers (1976: 19) concerning the name of the type species of Trichys Günther, 1877, is corrected in a foot note.

Notes on Southeast Asian Porcupines (Hystricidae, Rodentia). IV. On the taxonomy of the subgenus Acanthion F. Cuvier, 1823 with notes on the other taxa of the family
Provedor de dados: 16
Autores: Weers, D.J. van.
Arguments are presented to demonstrate that Lyon’s (1907) division of the Old World porcupines, family Flystricidae, into two subfamilies is superfluous and provides a distorted classification. Evidence is presented for the point of view that the generic status of Thecurus Lyon, 1907 has been based on quite insufficient arguments, and this taxon is not accorded a higher rank than that of a subgenus. Only three genera are recognized in this family: Trichys Günther, 1877, Atherurus F. Cuvier, 1829, and Hystrix Linnaeus, 1758 with the subgenera Hystrix s.s., Acanthion F. Cuvier, 1823 and Thecurus Lyon, 1907. Data about some south-western Asiatic specimens of Hystrix indica Kerr, 1792 are presented. The main subject of the present paper is the specific...

Notes on Southeast Asian Porcupines (Hystricidae, Rodentia) III. On the taxonomy of the subgenus Thecurus Lyon, 1907 (genus Hystrix Linnaeus, 1758)
Provedor de dados: 16
Autores: Weers, D.J. van.
The characters of the short-tailed porcupines with small nasals from Sumatra, Borneo and the Philippines, genus Hystrix Linnaeus, 1758, subgenus Thecurus Lyon, 1907, have been studied. As a result three species are recognized, namely: H. crassispinis Günther, 1877, H. pumila Günther, 1879, and H. sumatrae (Lyon, 1907). Evidence is brought forward for the valid specific status of these forms and data are presented to supplement the scarce information known about these species.
