Abstract
Population divergence leading to speciation is often explained by physical barriers causing allopatric distributions of historically connected populations. Environmental barriers have increasingly been shown to cause population divergence through local adaptation to distinct ecological characteristics. In this study, we evaluate population structuring and phylogeographic history within the Yucatán banded gecko Coleonyx elegans Gray 1845 to assess the role of both physical and environmental barriers in shaping the spatio-genetic distribution of a Mesoamerican tropical forest taxon. We generated RADseq and multi-locus Sanger datasets that included sampling across the entire species' range. Results find support for two distinct evolutionary lineages that diverged during the late Pliocene and show recent population expansions. Furthermore, these genetic lineages largely align with subspecies boundaries defined by morphology. Several mountain ranges identified as phylogeographic barriers in other taxa act as physical barriers to gene flow between the two clades. Despite the absence of a physical barrier between lineages across the lowland Isthmus of Tehuantepec, no introgression was observed. Here, a steep environmental cline associated with seasonality of precipitation corresponds exactly with the distributional limits of the lineages, whose closest samples are only 30 km apart. The combination of molecular and environmental evidence, and in conjunction with previous morphological evidence, allows us to reassess the current taxonomy in an integrative framework. Based on our findings, we elevate the previously recognized subspecies from the Pacific versant, the Colima banded gecko C. nemoralis Klauber 1945, to full species status and comment on conservation implications.

Abstract
A definition of the Goniurosaurusyingdeensis group is presented in this study, on the basis of morphological and phylogenetic analyses based on a series of additional specimens. Moreover, a new species of this group, Goniurosaurusvariussp. nov., is proposed for northern Guangdong Province, China. The new species can be distinguished from the other two congeners of this group by the following unique characters: one or two internasals; enlarged supraorbital tubercles absent; paravertebral tubercles between limb insertions 27–29; dorsal tubercle rows at midbody 21–24; ten precloacal pores in males and absent in females; body bands with black spots; iris orange-red.

Abstract
A new species of the genus Goniurosaurus is described based on three specimens collected from a limestone cave in Huaiji County, Guangdong Province, China. Based on molecular phylogenetic analyses, the new species is nested within the Goniurosaurus yingdeensis species group. However, morphological analyses cannot ascribe it to any known species of that group. It is distinguished from the other three species in the group by a combination of the following characters: scales around midbody 121-128; dorsal tubercle rows at midbody 16-17; presence of 10-11 precloacal pores in males, and absent in females; nuchal loop and body bands immaculate, without black spots; iris orange, gradually darker on both sides. The discovery of yet another limestone-adapted species of Goniurosaurus in Guangdong Province underscores a growing body of evidence for the high biodiversity of limestone habitats and brings into sharp focus the urgent need for their conservation.

Abstract
In this study, using Illumina sequencing data, we assembled the complete mitogenome of Goniurosaurus zhoui, which consists of 16,803 base pairs, comprising 13 protein-coding genes, 2 ribosomal RNA genes, 21 tRNA genes, and non-coding regions (D-loop), and has an overall A + T content of 60.39%. Using three complete 16S rRNA gene and 13 partial sequence data of the 16S rRNA gene, including that of G. zhoui, we reconstructed the phylogeny of the genus Goniurosaurus. The result of the Bayesian inference tree revealed four major, distinctly separated groups.
