We are pleased to share our latest publication reporting the first complete mitochondrial genomes of Cephenemyia auribarbis, Cephenemyia ulrichii, and Pharyngomyia picta, three bot flies belonging to the Oestridae family whose larvae are obligate parasites of mammals, developing in tissues such as the nasal cavities, pharynx or under the skin of wild and domestic ungulates, among others. Because larval stages are often morphologically similar, molecular approaches are essential for accurate identification and evolutionary studies. In this context, mitogenomics (i.e., the analysis of complete mitochondrial genomes) offers a powerful tool for species identification, phylogenetic reconstruction, and population analyses.

This work is the result of a strong collaborative effort between research groups in Spain and Russia. A key link between teams is our pathologist, R. Velarde, whose contribution of samples and wildlife health expertise highlights the value of sustained interdisciplinary collaboration. Overall, the paper expands available mitogenomic data for Oestridae and provides robust phylogenetic evidence supporting the monophyly of Cephenemyia and its close evolutionary relationship with Pharyngomyia, Oestrus, and Rhinoestrus.
