Table 1. List of species and specimens incorporated in the phylogenetic analysis, along with corresponding collection localities, COI gene haplotypes, GenBank accession numbers and references. Each specimen represents a population from a distinct locality. All the four haplotypes recovered from the TCS network were included in the phylogenetic analysis. The four GenBank accession numbers generated in this study correspond to the four identified haplotypes. Pisidia serratifrons (Stimpson, 1858) is the outgroup.
