﻿AbstractIntegrated 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 genusDixonius, 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 thatDixoniusgialaiensissp. nov.is the sister species ofD.minhleifrom Dong Nai Province, Vietnam and is nested within a clade that also includes the sister speciesD.siamensisandD.somchanhae.Dixoniusmuangfuangensissp. nov.is the sister species toD.laofrom Khammouane Province, Laos and is embedded in a clade withD.vietnamensis,D.taoi, and undescribed species from Thailand. Multivariate (PCA,DAPC, andMFA) 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 ofDixoniusfrom Vietnam and Laos clearly illustrateDixoniusgialaiensissp. nov.andDixoniusmuangfuangensissp. nov.are statistically different and discretely diagnosable from all closely related species ofDixonius. These integrative analyses also highlight additional taxonomic issues that remain unresolved withinDixoniusand the need for additional studies. The discovery of these new species further emphasizes the underappreciated herpetological diversity of the genusDixoniusand illustrates the continued need for field work in these regions.
