Neighbor-Joining tree of COI nucleotide sequences (codon positions 1, 2, and 3) from the Montserrat specimen of Chlamydotheca unispinosa, four of the most similar sequences and one outgroup. All positions containing gaps and missing data were eliminated. There was a total of 620 positions in the final dataset. Bootstrap values (1000 replicates) are shown at each node. Branch lengths represent evolutionary distances (p-distance) and are in the units of the number of base differences per site. All analyses were completed in MEGA 7 (Kumar et al. 2016).
