The diversity of lacertid lizards in Africa is highest in the southern African subcontinent, where over two-thirds of the species are endemic. With eleven currently recognized species, Pedioplanis is the most diverse among the southern African genera. In this study we use 2200 nucleotide positions derived from two mitochondrial markers (ND2 and 16S rRNA) and one nuclear gene (RAG-1) to (i) asse...

We describe a new lizard of the genus Potamites from elevations of 1000-2100 m in the montane forests of the Cordillera de Paucartambo and the upper Kosñipata valley, Region of Cusco, Peru. The new species differs from other species of Potamites by having scattered keeled scales on dorsum, an undivided frontonasal and absence of femoral pores in females.

Two new species of large geckos in the genus Goniurosaurus are described based on specimens collected from karst areas of Guangxi Zhuang Autonomous Region, southern China: Goniurosaurus kadoorieorum sp. nov. and Goniurosaurus kwangsiensis sp. nov. Data on natural history of the new species are provided, as well as discussions on the current conservation status of Goniurosaurus species in southe...

Despite much interest in amniote systematics, the origin of turtles remains elusive. Traditional morphological phylogenetic analyses place turtles outside Diapsida-amniotes whose ancestor had two fenestrae in the temporal region of the skull (among the living forms the tuatara, lizards, birds and crocodilians)-and allied with some unfenestrate-skulled (anapsid) taxa. Nonetheless, some morpholog...

Erhard's wall lizard, Podarcis erhardii (Sauria: Lacertidae), is highly diversified in Greece and especially in the southern Aegean region. Out of the 28 recognized subspecies, 27 are found in Greece from the North Sporades island-complex in the North Aegean (grossly south of the 39th parallel) to the island of Crete in the South. The species exhibits great morphological and ecological plastici...

A proximo-distal gradient of reduced glutathione (GSH), a non enzymatic antioxidant was observed in the original tails of the lizard, H. leschenaultii. In the regenerating tails, a gradual increase in the level of GSH was noted with tail elongation. In the newly regenerated tails also the level of GSH remained higher in the proximal part than the corresponding distal parts.

The study of the holotype and of a new specimen of Nanchangosaurus suni (Reptilia; Diapsida; Hupehsuchia) revealed a suite of hitherto unrecognized characters. For example, Nanchangosaurus has bipartite neural spines and its vertebral count is nearly identical to that of Hupehsuchus. It differs from the latter in having poorly developed forelimbs despite the advanced ossification in the rest of...
