Maximum likelihood tree of Empria based on three genes. Best-fit model chosen according to Bayesian information criterion was GTR+R3. Numbers beside nodes show SH-aLRT support (%) / ultrafast bootstrap support (%) values. Support values for weakly supported branches (<90) are not shown. Letters “f” and “m” stand for “female” and “male”. Numbers at the end of the tip labels refer to the length of the sequence and the number of ambiguous positions (e.g. polymorphisms). Empria candidata and E. multicolor were used to root the tree. The scale bar shows the number of estimated substitutions per nucleotide position.
