Tarsius lariang: A new primate species from western central Sulawesi
No full textOn the basis of morphological, anatomical, and acoustic analyses, the tarsiers of the Gimpu region on Sulawesi belong to a previously undescribed species of the genus Tarsius Storr, 1780. We describe the new taxon as Tarsius lariang new species. In November 2001, S. Merker collected 8 specimens of Tarsius lariang near Gimpu, Central Sulawesi, Indonesia. Four of them were transferred to the Indonesian Institute of Sciences at Cibinong to be held in an enclosure, and after their deaths become part of the collection of the Museum Zoologicum Bogoriense, Bogor. The new species is distinctive in pelage, skull, and body proportions, and in vocalization. We describe the unique territorial duet song characteristic for them and place the taxon into a biogeographic framework developed in previous studies

The Tenasserim Lutung, Trachypithecus barbei (Blyth, 1847) (Primates: Cercopithecidae): Description of a live specimen, and a reassessment of phylogenetic affinities, taxonomic history, and distribution
No full textThe Tenasserim lutung
Trachypithecus barbei
was previously known from museum specimens and field observations only. We discovered a zoo specimen and present the first confirmed evidence for the continued existence of the species since 1967. We describe the cranial pelage and coloration characteristics of this species which were previously unknown. We present first molecular evidence for recognizing
T. barbei
as a distinct species and for assessing its phylogenetic affinities relative to other members of the genus
Trachypithecus
. We document the taxonomic history of
T. barbei
and present a distribution map based on a compilation of all known locality records

The 'temporal effect' in hominids: Reinvestigating the nature of support for a chimp-human clade in bone morphology
No full textIn 2004, an analysis by Lockwood and colleagues of hard-tissue morphology, using geometric morphometrics on the temporal bone, succeeded in recovering the correct phylogeny of living hominids without resorting to potentially problematic methods for transforming continuous shape variables into meristic characters. That work has increased hope that by using modern analytical methods and phylogenetically informative anatomical data we might one day be able to accurately infer the relationships of hominins, including the closest extinct relatives of modern humans. In the present study, using 3D virtually generated models of the hominid temporal bone and a larger suite of geometric morphometric and comparative techniques, we have re-examined the evidence for a Pan-Homo clade. Despite differences in samples, as well as the type of raw data, the effect of measurement error (and especially landmark digitization by a different operator), but also a broader perspective brought in by our diverse set of approaches, our reanalysis largely supports Lockwood and colleagues' original results. However, by focusing not only mainly on shape (as in the original 2004 analysis) but also on size and 'size-corrected' (non-allometric) shape, we demonstrate that the strong phylogenetic signal in the temporal bone is largely related to similarities in size. Thus, with this study, we are not suggesting the use of a single 'character', such as size, for phylogenetic inference, but we do challenge the common view that shape, with its highly complex and multivariate nature, is necessarily more phylogenetically informative than size and that actually size and size-related shape variation (i.e., allometry) confound phylogenetic inference based on morphology. This perspective may in fact be less generalizable than often believed. Thus, while we confirm the original findings by Lockwood et al., we provide a deep reinterpretation of their nature and potential implications for hominid phylogenetics and we show how crucial it is not to overlook size in geometric morphometric analyses

A New Reconstruction of the Shanidar 5 Cranium
No full textA reconsideration of the Iraqi Neandertal Shanidar 5 cranium has demonstrated that the left parietal bone was incorrectly oriented. The proper orientation removes any indication of the mid-sagittal parietal profile of the specimen. It is therefore no longer possible to maintain that the individual experienced artificial cranial deformation, although Shanidar 5 and the other Shanidar Neandertal crania have unusual levels frontal mid-sagittal flatness.Une nouvelle observation du crâne néandertalien Shanidar 5 (Irak), a montré que, lors de sa reconstruction, le pariétal gauche avait été mal positionné. Une correction de l'orientation du pariétal enlève toute indication du profil sagittal des pariétaux. Il n 'est donc plus possible de maintenir que Shanidar 5 a subi une déformation artificielle du crâne et ce même si tous les crânes néandertaliens de Shanidar présentent un aplatissement frontal exceptionnel.Chech M., Groves Colin P., Thorne Alan, Trinkaus Erik.
