Fig. 8 in The Last Piece of the Puzzle? Phylogenetic Position and Natural History of the Monotypic Fungus-Farming Ant Genus Paramycetophylax (Formicidae: Attini)

Fig. 8. Time-calibrated phylogeny of the tribe Attini inferred from an MCMCTREE analysis (Yang and Rannala 1997). Red star indicates the origin of fungusfarming ants. Blue dots indicate fossil calibrations (see text). Colored boxes indicate the five agricultural systems: (i) lower agriculture (yellow); (ii) coral-fungus (Pterulaceae) agriculture (red); (iii) yeast agriculture (green); (iv) higher agriculture (blue); and (v) leaf-cutter agriculture (orange).Taxa in red correspond to anthead images on right:Cyphomyrmex costatus (top),Paramycetophylax bruchi (middle), and C. rimosus (bottom). Light blue bars indicate 95% highest probability density (HPD). K-Pg Event = Cretaceous/Paleogene boundary; EECO = Early Eocence Climatic Optimum;TEE = Terminal Eocene Event; MMCO = Middle Miocene Climatic Optimum.
