The hypothesis that a monophyletic Satyriinae was not
observed due to stochasticity of the substitution process
was rejected based on the parametric bootstrap. The observed
value of the difference in number of steps between a tree
with Satyriinae constrained to be monophyletic and the most
parsimious tree is 11. This value falls outside 99% of the values
that are obtained through parametric simulation of the null
distribution.
