Phylogenetic relationships of the five repleta group species and 19 previously sequenced Drosophila species based on concatenated codon alignments of 1802 orthogroups shared by all species. The divergence time was estimated using the RelTime [102] package in MEGA7 [93]. All bootstrap values for nodes from 1000 iterations were equal to 1 and the ancestral repleta group branch is indicated with a hash
