Best inferred ML phylogenetic tree with summarised groups based on amino acid sequences from 1130 genes and 70 schizophoran taxa (Table 1: Analysis 2). For the full tree, see Fig. S2, Additional file 6. Statistical non-parametric BS support was inferred from RAxML v8 bootstrapping. Circles visualise the proportions of quartets determined with ASTRAL-III scoring the best ML tree. Red proportions indicate the number of quartets that are concordant with the best ML tree; blue and yellow indicate the proportions of quartets that support the two alternate quartet topologies. Atelestidae + other Empidoidea was used as the root. Three species are collapsed in ‘Other Empidoidea’, three in Phoroidea, two in Syrphidae, two in Nerioidea, three in Tephritoidea, two in Steganinae, four in Drosophilinae, two in Pupipara, and five in Oestroidea
