The nucleotide in bold underlined are the SNP diagnostic of the species considered. For example, in position 54 of the aligned sequences, the nucleotide T in bold underlined is present in all sequences of the O. normandi and absent in any sequences of other species. Other example, in position 244 the nucleotides A and C are diagnostic for O. costalis. No. seq.: number of analyzed sequences.
