Abstract

Ectinogonia is a genus of jewel beetles from the western slope of the Andes Cordillera, inhabiting arid and semiarid ecosystems in different biogeographical provinces. Most of the species in this genus have undergone several rearrangements and misassignments over time, making the taxonomic history of Ectinogonia particularly complex. Recent studies based on molecular phylogenies suggest that the taxonomy of the genus should be revised using genetic tools. Because some species are polymorphic and others cryptic and monomorphic, species diversity may be over- or underestimated. We performed here the first comprehensive molecular phylogeny for Ectinogonia s.s. using nuclear and mitochondrial genes. We also performed species delimitation analyses to estimate diversity within Ectinogonia. Results show that Ectinogonia is divided into two main groups: the artificial 'southern group' and the natural 'northern clade'. The southern group matched with the current morphology-based taxonomy, whereas the northern clade contained the largest number of species, several of which do not fit with the current taxonomy. There was both genetic-morphological uncoupling and crypsis by convergence, suggesting a complex evolutionary history. We also provide a new taxonomic arrangement based on our results.
