Maximum likelihood tree of Empria parvula and E. pravei specimens based on mitochondrial COI. Best-fit model chosen according to Bayesian information criterion was HKY+I. Numbers above branches 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. The scale bar shows the number of estimated substitutions per nucleotide position.
