Fig. 1

Species phylogeny from nuclear data in Habronattus (for branch lengths, see Fig. 2a), and main conclusions of nuclear introgression. a Maximum likelihood tree from 1877 concatenated nuclear loci (2.41mb alignment; RAxML); largely concordant with the ASTRAL tree (stars). Colours mark species groups as labeled. Legend for decorations at lower left. Bootstrap percentages for ML analysis of concatenated nuclear matrix. Spots and vertical bars show presence of clade in the ML tree for various partitions of the data (black = clade present). Spots show presence of clade in tree for each of the 1/8th portions of concatenated nuclear loci. Vertical bars show presence of clade in the trees from the remnant Missing Species (MS) and the Noncoding Loci (NL) matrices. Stars show clades present in ASTRAL analysis of 1020 ML gene trees of alignment length at least 1000 bp. Diamonds show clades with (black) > 94% or (grey) 75-94% bootstrap support in SVDQuartets analysis. Discordant results shown by grey arrows with circle (concatenated ML bootstrap consensus) or star (ASTRAL). For instance, the concatenated bootstrap consensus places H. cambridgei as sister to oregonensis, and H. icenoglei in a more basal position with respect to the VCCR clade. From b to d: Conclusions of introgression from D-statistics and BCA for b the americanus group, c H. roberti and the VCCR clade, and d the clypeatus and coecatus groups.
