We describe a new species of Amphiglossus skink from the western edge of the Central Highlands of Madagascar in the Reserve of Makira, and also found in the Reserve Speciale of Ambohijanahary and in the Reserve Speciale of Marotandrano. Amphiglossus meva n. sp. is characterized and differentiated from other species of the genus by a combination of morphological, chromatic and molecular characters: 1) a relatively large size (SVL of adults from 126 to 150 mm); 2) a characteristic pattern of…

Variations on a bauplan: description of a new Malagasy “mermaid skink” with flipper-like forelimbs only (Scincidae, Sirenoscincus Sakata & Hikida, 2003)
This study highlights the importance of the rare “forelimbs only bauplan” for investigating macroevolutionary questions dealing with complete limb loss in vertebrates, a convergent phenomenon that has repeatedly occurred 16 to 20 times within Scincidae Gray, 1825.
Species delimitation methods put into taxonomic practice: two new Madascincus species formerly allocated to historical species names (Squamata, Scincidae)
Some aspects of the biogeographic patterns characterising the different main clades within the genus Madascincus are provided and discussed for the first time in the light of a robust phylogenetic framework.
Distinct Patterns of Desynchronized Limb Regression in Malagasy Scincine Lizards (Squamata, Scincidae)
Preliminary reconstructions suggest rapid limb regression in Malagasy scincids with an estimated maximal duration of 6 MYr for a complete regression in Paracontias, and 4 and 8 MYr respectively for complete regression of forelimbs in Grandidierina and hind Limbs in Voeltzkowia.

New Metrics for Comparison of Taxonomies Reveal Striking Discrepancies among Species Delimitation Methods in Madascincus Lizards
Quantifying excessive splitting is more difficult than quantifying excessive lumping, suggesting a priority for conservative taxonomies in which errors are more liable to be detected and corrected by subsequent studies.


A further new species of limbless skink, genus Paracontias, from eastern Madagascar
A new species of the genus Paracontias from a rain forest in the northern Central East of Madagascar based on a single specimen is described by exhibiting large loreals meeting each other in midline dorsally, separating the rostral from the frontonasal scale.
Systematics of limbless scincid lizards from northern Madagascar: morphology, phylogenetic relationships and implications for classification (Squamata: Scincidae)
Morphology in fossorial skinks is well suited to distinguish species, but is of rather limited value to elucidate phylogenetic relationships, and molecular relationships among seven Paracontias species are compared to external morphological characters formerly used in skink systematics.
Malagasy scincid lizards: descriptions of nine new species, with notes on the morphology, reproduction and taxonomy of some previously described species (Reptilia, Squamata: Scincidae)
The taxonomy and/or natural history of 33 species of scincid lizards from Madagascar are reviewed and nine new species are described, increasing the known skink fauna of Madagascar by 14.5%.
Opening the black box: phylogenetics and morphological evolution of the Malagasy fossorial lizards of the subfamily "Scincinae".
A molecular phylogeny of the “ Madascincus polleni species complex”, with description of a new species of scincid lizard from the coastal dune area of northern Madagascar
Evidence is provided for the existence of at least four distinct evolutionary lineages within the Malagasy skink genus Madascincus, currently encompassing the nominal species M. polleni, M. intermedius and M. stumpffi.
Four new species of Amphiglossus from Madagascar (Squamata: Scincidae)
Four new species of Madagascan skinks (Amphiglossus) are described from rainforest localities surveyed in the east, southeast, and northwest between 1988 and 1991, with the first member of the genus known to be viviparous.
Molecular phylogenetics of Malagasy skinks (Squamata: Scincidae)
A phylogeny of Malagasy “scincine” lizards is presented, based on quantitative phylogenetic analysis of data from seven molecular markers, which confirms the paraphyly of "Amphiglossus”, and supports Madascincus as a valid genus.
Hypotheses on rostral shield evolution in fossorial lizards derived from the phylogenetic position of a new species of Paracontias (Squamata, Scincidae)
The hypothesis that the rostral shield may provide several functional advantages for fossorial species in facilitating burrowing and protecting the head from strong physical stress is developed, e.g. smoother surface reducing friction between the teguments and the substrate, reduction in the number of flexible sutures resulting in strengthened tegument, and the roStral tip likely playing a role as a shock-absorbing buffer.
Vast underestimation of Madagascar's biodiversity evidenced by an integrative amphibian inventory
The results suggest that in Madagascar the spatial pattern of amphibian richness and endemism must be revisited, and current habitat destruction may be affecting more species than previously thought, in amphibians as well as in other animal groups.
