- Abstract
As one of the most distinct groups in the hoverfly genus Merodon, the monophyletic ruficornis species group has been the focus of several studies using different approaches. Molecular methods have shown incongruences between morphological and molecular data. In the present study, we investigated four species of the Merodon ruficornis group (i.e. M. loewi, M. armipes, M. papillus and M. hoplitis) with the aim of detecting intra and interspecific genetic diversity and we examined the usefulness of random amplified polymorphic DNA (RAPD) in an integrative taxonomic approach to species delimitation. Analysis of Nei's genetic variation over all loci showed that genetic diversity for the analyzed Merodon species was h=0.24. Based on UPGMA, PCoA and Bayesian clustering analyses, our results clearly differentiated four groups that correspond to the four morphologically-defined Merodon species. Among the analyzed species, M. armipes and M. hoplitis showed the lowest level of genetic divergence; M. loewi was clearly separated from both M. armipes and M. papillus. Based on our data, we propose the use of RAPD-PCR as an additional tool for resolving taxonomic problems within Merodon.
