  1. Top four rows, “all” lineages = lineages differing by ≥ 3 observed mutations in mtCOI. Bottom four rows: results of analyses of tree truncated at 1 Ma. A significantly negative gamma indicates slowing of diversification near the present, and is most strongly affected by the most recent splits. P values shown assume complete taxon representation, calculated directly from the gamma statistics as shown by Pybus and Harvey [31]. The maximum percent missing column shows the highest percentage of missing taxa (in 10% increments) for simulations in which adjusted critical values for γ were higher than the γ value shown. ns indicates that the gamma value was not significant compared to the simulated null distribution even assuming complete taxon sampling
