TABLE 3. The maximum distances within each clade or singleton lineage and minimum distances between each pair of them, calculated based on the COI sequence dataset. The upper right diagonal shows the distance in the K2P model, and the lower left diagonal shows the p-distance (%). N, number of specimens of the clade or singleton lineage; max p, maximum p distance within the clade or singleton lineage; max K2P, maximum distance in K2P model within the clade or singleton lineage.
