Table 2. Range and average (in parentheses) of Kimura 2-parameter distances among and between ‘species’ that were estimated by three different delimitation analysis methods (ABGD, PTP, TCS), based on a total of 487 sequences of COI gene (~658 bp), of which 462 were available in GenBank and 25 were generated de novo in this study.
