The global distribution of tetrapods reveals a need for targeted reptile conservation.

The distributions of amphibians, birds and mammals have underpinned global and local conservation priorities, and have been fundamental to our understanding of the determinants of global biodiversity. In contrast, the global distributions of reptiles, representing a third of terrestrial vertebrate diversity, have been unavailable. This prevented the incorporation of reptiles into conservation planning and biased our understanding of the underlying processes governing global vertebrate biodiversity. Here, we present and analyse the global distribution of 10,064 reptile species (99% of extant terrestrial species). We show that richness patterns of the other three tetrapod classes are good spatial surrogates for species richness of all reptiles combined and of snakes, but characterize diversity patterns of lizards and turtles poorly. Hotspots of total and endemic lizard richness overlap very little with those of other taxa. Moreover, existing protected areas, sites of biodiversity significance and global conservation schemes represent birds and mammals better than reptiles. We show that additional conservation actions are needed to effectively protect reptiles, particularly lizards and turtles. Adding reptile knowledge to a global complementarity conservation priority scheme identifies many locations that consequently become important. Notably, investing resources in some of the world's arid, grassland and savannah habitats might be necessary to represent all terrestrial vertebrates efficiently.

Acanthosaura phuketensis (Squamata: Agamidae), a new long-horned tree agamid from southwestern Thailand.

We describe a new lowland forest-dwelling species of the genus Acanthosaura from Phuket Island and the Phuket mountain range in southwestern Thailand. Acanthosaura phuketensis sp. nov., the 11th species in the genus, seems most closely related to A. crucigera from Myanmar and western Thailand and A. cardamomensis from the Cardamom Mountains, but can be differentiated from them by a combination of morphological and coloration characteristics. This new discovery stresses the importance of preserving the last forest patches remaining on Phuket Island, home to three other squamate endemics.

New species of Cosmocercoides (Nematoda; Cosmocercidae) and other helminths in Gonocephalus liogaster (Squamata; Agamidae) from Peninsular Malaysia.

Cosmocercoides malayensis sp. nov. (Nematoda, Cosmocercidae) from the large intestine of Gonocephalus liogaster (Squamata, Agamidae) from Peninsular Malaysia is described and illustrated. Cosmocercoides malayensis sp. nov. represents the 23rd species assigned to the genus and the 10th species from the Oriental biogeographical region. Cosmocercoides malayensis sp. nov. differs from the previously described Oriental species in number and position of rosette papillae; however, it is most similar to C. bufonis and C. rickae in that these 3 species have 6 post cloacal rosette papillae. Cosmocercoides bufonis possesses a prebulbar copular swelling, which is absent in C. malayensis; C. rickae posssesess somatic papillae, which are absent in C. malayensis. Three addtional nematode species were found, adult specimens of Meteterakis singaporensis and Orneoascaris sandoshami and larva of Physocephalus sp.

New species of Oswaldofilaria (Nematoda; Filarioidea; Onchocercidae) and other helminths in Acanthosaura cardamomensis (Sauria; Agamidae) from Indochina Peninsula.

Oswaldofilaria acanthosauri sp. nov. from the body cavity of the Cardamom Mountain horned agamid, Acanthosaura cardamomensis (Sauria: Agamidae), collected in Pursat Province, Cambodia is described. Of the 14 species assigned to Oswaldofilaria, O. acanthosauri sp. nov. is most similar to those species with spicular ratio of less than 2, namely, O. brevicaudata and O. chlamydosauri. Oswaldofilaria acanthosauri sp. nov. is easily separated from these 2 species in that O. brevicaudata is a South American species and in O. chlamydosauri the distal ends of the spicules are pointed not blunt. Mature individuals of 2 additional species of Nematoda, Meteterakis singaporensis and Orneoascaris sandoshami, as well as larvae assignable to Ascariidae were found. Acanthosaura cardamomensis represents a new host record for Meteterakis singaporensis, Orneoascaris sandoshami and Ascariidae (larvae).

Phylogenetic relationships of Ansonia from Southeast Asia inferred from mitochondrial DNA sequences: systematic and biogeographic implications (Anura: Bufonidae).

We investigated the phylogenetic relationships and estimated the history of species diversification and biogeography in the bufonid genus Ansonia from Southeast Asia, a unique organism with tadpoles adapted to life in strong currents chiefly in montane regions and also in lowland rainforests. We estimated phylogenetic relationships among 32 named and unnamed taxa using 2461bp sequences of the mitochondrial 12S rRNA, tRNA(val), and 16S rRNA genes with equally-weighted parsimony, maximum likelihood, and Bayesian methods of inference. Monophyletic clades of Southeast Asian members of the genus Ansonia are well-supported, allowing for the interpretation of general biogeographic conclusions. The genus is divided into two major clades. One of these contains two reciprocally monophyletic subclades, one from the Malay Peninsula and Thailand and the other from Borneo. The other major clade primarily consists of Bornean taxa but also includes a monophyletic group of two Philippine species and a single peninsular Malaysian species. We estimated absolute divergence times using Bayesian methods with external calibration points to reconstruct the relative timing of faunal exchange between the major landmasses of Southeast Asia.
