Phylogenetic analyses based on 1459 base pairs of the mitochondrial gene ND2 and its flanking tRNAs indicate that Cyrtodactylus consobrinus from the type locality in Sarawak, East Malaysia (Borneo) and C. consobrinus from Peninsular Malaysia are not conspecific. Both populations as well as C. hutan from East Malaysia form a strongly supported monop...

A new species of karst-dwelling Bent-toed Gecko (genus Cyrtodactylus) is described from an unexplored karstic archipelago in western Cambodia. Cyrtodactylus kampingpoiensissp. nov. is composed of four allopatric, monophyletic mitochondrial lineages based on the ND2 gene. All are statistically diagnosable from one another based on univariate (ANOVA)...

The rediscovery and photographic documentation of Sphenomorphus anomalopus from Gunung Leuser National Park in North Sumatra, Indonesia, after a 109-year hiatus allowed us, for the first time, to observe its behavior and assess its microhabitat. Historical descriptions of this species’ coloration were never based on live material and, as such, did...

Sphenomorphus stellatus was once thought to be a wide-ranging species distributed across many parts of Indochina, the Thai-Malay Peninsula and Borneo. However, recent integrative taxonomic studies on the species have revealed its underestimated diversity and new species previously masquerading under this nomen in mainland Southeast Asia. This promp...

Adaptive radiations garner considerable interest from evolutionary biologists. Lizard radiations diversifying along structural niche space often exhibit distinct changes in body and limb proportions. One prediction is that terrestrial species inhabiting open habitats will have relatively longer hindlimbs, associated with faster running speeds, whil...
Article
Limnonectes hascheanus and Limnonectes limborgi are two very similar-looking and closely related species and are sometimes referred to as the Limnonectes hascheanus-limborgi complex (Inger & Stuart 2010). Inger & Stuart (2010) tackled the systematics of the complex and confirmed the status of L. limborgi as a distinct species and not a junior synon...

Environmental factors, such as temperature, precipitation, and elevation, explain most of the variation in species richness at the global scale. Nevertheless, richness patterns may have different drivers across taxa and regions. To date, a comprehensive global examination of how various factors such as climate or topography drive patterns of specie...
Article
We use data sets from the Cyrtodactylus brevipalmatus group with limited genetic and morphological sampling to demonstrate that not accounting for sampling error may adversely influence decisions regarding species delimitation and diagnosis.

Full-text available
Species delimitation and species diagnosis must remain separate operations to avoid constructing taxonomies comprised of non-monophyletic species based on morphological similarity as opposed to phylogenetic propinquity. This is particularly true for highly specialized species such as the range-restricted upland taxa in the Cyrtodactylus brevipalmat...
