The gekkonid genus Cyrtodactylus is a highly diverse group of lizards (280 + species), which covers an expansive geographic range. Although this genus has been the focus of many taxonomic and molecular systematic studies, species on the Southeast Asian island of Borneo have remained understudied, leading to an unclear evolutionary history with cascading effects on taxonomy and biogeographic inferences. We assembled the most comprehensive multilocus Bornean dataset (one mitochondrial and three…

Recent phylogenetic studies of gekkonid lizards have revealed unexpected, widespread paraphyly and polyphyly among genera, unclear generic boundaries, and a tendency towards the nesting of taxa exhibiting specialized, apomorphic morphologies within geographically widespread "generalist" clades. This is especially true in Australasia, where monophyly of Gekko proper has been questioned with respect to phenotypically ornate flap-legged geckos of the genus Luperosaurus, the Philippine false geck…

An integrative taxonomic analysis based on morphology, color pattern, and the mitochondrial gene ND2 recovered four new species of Hemiphyllodactylus Bleeker that are endemic to the Shan Plateau or Salween Basin in eastern Myanmar. Hemiphyllodactylus ngwelwini sp. nov. from the Shan Plateau is part of the earlier described "eastern Myanmar clade" renamed herein as the north lineage and H. kyaiktiyoensis sp. nov. and H. pinlaungensis sp. nov. of the Shan Plateau and H. zwegabinensis sp. nov. o…

Abstract The first molecular phylogeny for mountain reed snakes (genus Macrocalamus) based on the mitochondrial gene cytochrome b is not entirely consistent with the previous taxonomy based on morphology and colour pattern. Macrocalamus chanardi is shown to be a species complex composed of three different allopatric lineages distributed across different upland areas in Peninsular Malaysia that are morphologically conserved but genetically distinct. A new and morphologically different species,…

Fifty-eight percent of the 43 known species of the Bent-toed Geckos (Cyrtodactylus) from Myanmar are found only in karstic habitats in the Shan Plateau and Salween and Ayeyarwady basins. A stochastic character mapping analysis indicated that the occupation of karstic habitats evolved at least four times independently in Burmese lineages with both Sundaic and Indian origins. Karstic habitats not only serve as foci for speciation but are refugia for species extirpated from the surrounding fores…

Historical and contemporary processes shaping striking variation in terrestrial biodiversity along elevational gradients have received much attention from evolutionary biologists, often by way of comparisons to latitudinal environmental gradients. Here we synthetically review what is known of the diversity and origin of upland endemic geckos across the Malesian region (south-east Asia and Melanesia). Approximately 20% of the regional gecko fauna is endemic to mountains, but only around 8% hav…

A reappraisal of the taxonomic status of the Dark-necked Slug Snake (Asthenodipsas malaccana Peters, 1864) across its range revealed that populations from Borneo are not conspecific with true A. malaccana from the Thai-Malay Peninsula and Sumatra, and is therefore described herein as new. Asthenodipsas borneensis sp. nov. can be distinguished from A. malaccana and other congeners by the absence of a preocular and suboculars, seven or eight supralabials with 3rd and 4th in contact with orbit, …

The historical accuracy of building taxonomies is improved when they are based on phylogenetic inference (i.e., the resultant classifications are less apt to misrepresent evolutionary history). In fact, taxonomies inferred from statistically significant diagnostic morphological characters in the absence of phylogenetic considerations, can contain non-monophyletic lineages. This is especially true at the species level where small amounts of gene flow may not preclude the evolution of localized…

An integrative taxonomic analysis of the 10 species of the Cyrtodactylus sinyineensis group based on squamation, color pattern, and the mitochondrial gene NADH dehydrogenase subunit 2 (ND2) and its flanking tRNA regions, recovered the newly discovered populations from Datt Kyaik and Taung Wine Hills in Kayin State as the new species Cyrtodactylus dattkyaikensis sp. nov. and C. taungwineensis sp. nov. The Maximum Likelihood and Bayesian phylogenetic estimates supported C. dattkyaikensis sp. no…

The brown anole, , is a native species to the Caribbean; however, has invaded multiple parts of the USA, including Florida, Louisiana, Hawai'i and more recently California. The biological impacts of invading California are currently unknown. Evidence from the invasion in Taiwan shows that they spread quickly and when immediate action is not taken eradication stops being a viable option. In Orange County, California, five urban sites, each less than 100 ha, were surveyed for an average of 49.2…
