Abstract
The thin-toed geckos of the Cyrtopodion agamuroides-gastropholis species complex represent a taxonomically challenging group of geckos whose systematic and phylogenetic relationships remain poorly resolved. A dataset comprising 251 specimens belonging to the agamuroides-gastropholis complex was analyzed, based on material collected over a period of 20 years. A morphological comparison of external features revealed a high degree of species diversity within this group. We present the first preliminary data from analysis of the mitochondrial DNA barcoding (COI). The species delimitation analysis is consistent with the morphologically based species diversification, allowing an estimation of the species diversity within this group. The results of this study have led to the description of ten new species of the agamuroides-gastropholis complex, conditionally placed in the genus Cyrtopodion. The present study also discusses the biogeography, evolution, and speciation of this group. Further revision of the genus taxonomy of these geckos is needed, as well as a more detailed genetic and genomic study.
