Two new species of from Vietnam and Laos with a discussion of the taxonomy of (Squamata, Gekkonidae).

Integrated analyses using maximum likelihood (ML), Bayesian inference (BI), principal component analysis (PCA), discriminate analysis of principal components (DAPC), multiple factor analysis (MFA), and analysis of variance (ANOVA) recovered two new diagnosable species of gekkonid lizards in the genus , one from the Central Highlands, Gia Lai Province, Vietnam and another from the Vientiane Province, Laos. Phylogenetic analyses based on the mitochondrial NADH dehydrogenase subunit 2 gene (ND2) and adjacent tRNAs showed that is the sister species of from Dong Nai Province, Vietnam and is nested within a clade that also includes the sister species and . is the sister species to from Khammouane Province, Laos and is embedded in a clade with , , and undescribed species from Thailand. Multivariate (PCA, DAPC, and MFA) and univariate (ANOVA) analyses using combinations of 15 meristic (scale counts), six morphometric (measurements), and five categorical (color pattern and morphology) characters from 44 specimens encompassing all eight species of from Vietnam and Laos clearly illustrate and are statistically different and discretely diagnosable from all closely related species of . These integrative analyses also highlight additional taxonomic issues that remain unresolved within and the need for additional studies. The discovery of these new species further emphasizes the underappreciated herpetological diversity of the genus and illustrates the continued need for field work in these regions.
