Figure 1.

Time-calibrated phylogeny of Blattodea. Topology obtained from ML analysis of the decisive amino acid (aa) dataset (585 040 aa positions). Coloured circles represent BS support. Node dates (posterior mean) were inferred using the decisive aa dataset reduced to sites containing 95% or more data completeness, and nine exhaustively vetted fossil calibrations. Error bars represent 95% confidence intervals. Fossils used for calibrations indicated as numbers in black circles are: 1: Cretaholocompsa montsecana; 2: Archeorhinotermes rossi; 3: Valditermes brenanae; 4: ‘Gyna’ obesa; 5: Qilianiblatta namurensis; 6: Juramantophasma sinica; 7: Alexarasnia rossica; 8: Raphogla rubra; 9: Protelytron permianum; see also electronic supplementary material, table S8. Abbreviations: ‘Eukinola.’ = Eukinolabia and ‘Xenono.’ = Xenonomia.
