Megjegyzések:The designation of taxonomic units has important implications on the way we study, understand and catalogue biodiversity, as well as on how we mobilize efforts and allocate funds to develop conservation strategies. Eurasian vipers are a monophyletic group (Serpentes, Viperinae), currently comprising four genera (Daboia, Macrovipera, Montivipera and Vipera) and up to 40 species. This group has a long and complex taxonomic history, and thus, taxonomic units have been defined and described using a wide variety of methods and criteria. Consequently, considerable controversy still surrounds the validity of some of the currently listed species. In order to advance towards a consensual and evidence-based taxonomy of Eurasian vipers, we analyzed published mitochondrial and nuclear DNA sequences for this group to identify phylogenetic relationships within currently recognized viper species. We also compiled information on external morphology to address the morphological distinctiveness of currently recognized species. Our mtDNA phylogenetic inferences show contrasting levels of divergence across the different species and some species with paraphyletic positions. The nuclear data show extremely low levels of genetic variation, with a wide pattern of haplotype sharing among distant species, and even among genera. Our morphological data compilation shows that most species designations rely on scalation traits that largely overlap among species of the same genus. Based on our combined assessment, we provide recommendations on the specific status of described species, and also propose further directions of research to achieve the recognition of coherent taxonomic units within Eurasian vipers.
