Inferred phylogenetic tree for the partial mitochondrial DNA cox1 gene using the maximum likelihood method, the general time reversible model with a gamma distribution and invariant sites and 2000 bootstrap replications. Reference sequences retrieved from GenBank (https://www.ncbi.nlm.nih.gov/genbank/) include accession number, species and country information. Haplotypes identified in this study (Ob01–Ob19) are highlighted in bold and by a black circle, while Spanish haplotype sequences identified from retrieved GenBank sequences (Ob20–Ob25) are marked by a gray triangle and include the accession number
