摘要

The members of the Indochinese box turtle complex, namely , , and , rank the most critically endangered turtle species on earth after more than three decades of over‐harvesting for food, traditional Chinese medicine, and pet markets. Despite advances in molecular biology, species boundaries and phylogenetic relationships, the status of the .  complex remains unresolved due to the small number of specimens observed and collected in the field. In this study, we present analyses of morphologic characters as well as mitochondrial and nuclear DNA data to reconstruct the species boundaries and systematic relationships within the .  complex. Based on principal component analysis (PCA) and statistical analysis, we found that phenotypic traits partially overlapped among , , and , and that and might be only subspecifically distinct. Moreover, we used the mitochondrial genome, , and nuclear gene under the maximum likelihood criteria and Bayesian inference criteria to elucidate whether could be divided into three separate species or subspecies. We found strong support for a sister relationship between and the other two species, and consequently, we recommend maintaining as a full species, and classifying and as subspecies of . These findings provide evidence for a better understanding of the evolutionary histories of these critically endangered turtles.
