Taxonomy, phylogeny and biogeography of myrmicine ants : insight from Cenozoic fossils
With more than 7000 species, the myrmicine ants constitutes one of the most successful ecological successes in history. Yet, their evolutionary history remains poorly understood. The present work attempts to trace their evolution through the taxonomic study of recent discoveries of fossil myrmicines...

With more than 7000 species, the myrmicine ants constitutes one of the most successful ecological successes in history. Yet, their evolutionary history remains poorly understood. The present work attempts to trace their evolution through the taxonomic study of recent discoveries of fossil myrmicines (Eocene Oise amber, Miocene Zhangpu and Ethiopian amber), in order to use them as new calibration points.The approach combines the most recent data-processing tools that allow a better consideration of palaeontological data (diversification, sampling rate, etc.), and their integration into phylogenetic analysis (FBD model, CladeAge). The effect of various calibration modes (root node calibration, crown- or stem- calibration, distribution models, node-dating vs. tip-dating) on divergence dating estimates is also tested and discussed. Finally, the biogeographical history is reviewed in the light of new occurrences and phylogenetic results. The group would have appeared in the New World during Upper Cretaceous (85-95 Ma), but without clearly indicating a stronger affiliation to Nearctic or Neotropic.
