Historical biogeography of the tribe Apameini reconstructed using the DEC model based on the median-BEAST chronogram.

<p>A coloured square indicating the most likely ancestral area is displayed at each node of the topology. Colours of the squares correspond to the colour of the areas presented in the map at the bottom left corner of the chronogram. Asterisks above the nodes indicate a strong support for the recovered areas (>2 log-likelihood units against the second better score). A 5 Myr-timescale is placed at the bottom of the chronogram and goes from the mid-Oligocene to the Holocene. The vertical bars next to the genera names delimit the two subtribes (Apameina in orange and Sesamiina in green). The biogeographical scenario for the tribe is presented in two maps at the bottom of the figure. Dotted-lines above the maps specify the related epoch (Left map: Oligocene and right map: Miocene). The origin of the group is highlighted by a yellow and red symbol, and the major dispersal events are shown with arrows.
