Table 3.

Information on the DNA datasets of Unionicola (U), Piona (P) and the combined dataset (U + P). Number of base pairs (BP), parsimony informative sites (PI), variable sites (V), constant sites (C), and the percentage of AT base pairs (AT%), for the COI and 28S sequences. The COI sequence is divided into first, second, and third codon positions
