Mean pairwise distances (m.p.d.) for the 245 bp long fragment of the COI gene in several monogenean taxa.

Legend for column Order: P is for Polyopisthocotylea, M for Monopisthocotylea. m.p.d: mean of pairwise distances. Species for which at least 3 sequences were available were included in the analysis.列“Order”的图例说明：P代表多后盘亚纲（Polyopisthocotylea），M代表单后盘亚纲（Monopisthocotylea）。m.p.d为两两距离均值（mean of pairwise distances）。本次分析仅纳入拥有至少3条序列的物种。
