(Number) corresponds to the numbers mentioned in figures 1 and 2, (n) number of specimens collected for each species, (locations) are [NAME] (B), Paulina (P), Zeedorp (Z), [NAME] (K), Nieuwpoort (N), or permanent lab cultures (C). Locations between brackets indicate where other specimens of the species have been found. (Sequence length) indicates length of the sequences, lengths in bold were amplified with [NAME], a dash indicates ambiguous sequences, blank spaces indicates a lack of PCR product to sequence, italic lengths indicate sequences from previous studies. (Accession numbers) provides the accession numbers for [NAME] and M1-M6, with numbers in bold taken from previous studies. (Indels) presence of indels in the sequence alignment is indicated by x.
