Maximum likelihood tree of Pristiphora based on COI gene (1078 bp). Shortest sequence included was 462 bp (subarctica MHV00166). Numbers above branches show bootstrap proportions (%). Support values for weakly supported branches (BP<70) are not shown. BIN numbers (BOLD:XXXXXXX) referred to in the text are shown for representative specimens. Part of Pristiphora is shown without support values and tip labels, which are shown in Figs 4–5. The scale bar shows the number of estimated substitutions per nucleotide position.
