Data from: Across the Indian Ocean: a remarkable example of trans-oceanic dispersal in an austral mygalomorph spider

Maximum likelihood analysisMaximum likelihood analysis was undertaken using RAxML on the BlackBox server for the combined six gene, 4118 character, 36 taxa dataset. COI, H3 and XPNPEP3 partitioned by codons and ITS1, 5.8S, ITS2 and 28S partitioned individually, with the GTR + G model used for all genes. This analysis resolved the genera Moggridgea and Bertmainius as reciprocally monophyletic, with M. rainbowi from KI clearly embedded within the African Moggridgea lineage and sister to M. intermedia (bootstrap value 100) (Fig 1). Furthermore, M. rainbowi formed a monophyletic group, but showed phylogeographic structure, with haplotypes reflecting the two geographic locations (Western River and American River). The MrBayes analysis of the same dataset produced a completely concordant tree.RAxML_tree.pdf
