Chronogram based on mtDNA tree. Bayesian ultrametric tree of Metacrangonyx longipes obtained using an uncorrelated log-normal relaxed clock assuming a coalescent model with constant population size. Dating of major clades was performed assuming a substitution rate fixed at 2.3% pair-wise divergence per million years.
