Phylogeny and divergence time estimation
The three analyses with different molecular clocks were equally supported (BF = ~1, Table S12, Table S13). The phylogenetic reconstruction is mostly congruent with published topologies and has good support overall (Figure 2, 3 Figure S3) (Ortiz-Acevedo et al., 2017; Ortiz-Acevedo and Willmott, 2013). The origin of Preponini was estimated at ~27.6 Ma in the Oligocene, that ofArchaeoprepona and Mesoprepona in the mid-Miocene ~13 Ma, and Prepona in the late Miocene ~8 Ma (Figure 2, 3 Figure S3). The red Preponaclade originated in the early Pliocene, ~5 Ma.
