Figure 2. Figure 2 in Aedeagus evolution promotes speciation? A primary pattern in rove beetle phylogeny

Figure 2. Figure 2. Phylogeny of the subfamily Staphylininae with divergence time estimates based on the concatenated sequence. Blue bars at each node show 95% highest posterior density interval for the main nodes. Colored branches and circled capital letters are as in Figure 1. Circled numbers refer to three main sub-clades within Clade A discussed in text. Circled roman letters represent the calibration points. Capital letter 'A', 'P' and 'N' represent aedeagus, paramere and species number of each corresponding genus respectively. Colored arrows refer to phylogenetic patterns of aedeagus morphology discussed in text. Dot lines with lower case letters refer to divergence times discussed in text. The abbreviation of geological ages are as follows: Jur—Jurassic; Cre—Cretaceous; Pal— Paleocene; Eoc—Eocene; Oli—Oligocene; Mio—Miocene; Pli—Pliocene.
