The mitochondrial genome is a prominent research topic due to its indispensable role in organisms and its application in many research disciplines. However, few studies have investigated intraspecies mitogenomic variation. In this study, 69 mitogenomes of the Black-throated Tit (Aegithalos concinnus) were assembled and annotated from a large number of short reads generated using high-throughput sequencing technology. Comparative analyses revealed that mitogenomic characteristics such as length, gene and nucleotide composition, codon usage, and duplicated control regions were relatively conserved despite substantial intraspecies morphological changes. Yet, all the individuals from the subspecies A. c. iredalei had one more nucleotide in the 12S rRNA than the other studied subspecies. Phylogenetic analyses showed five distinct lineages based on the complete mitogenomes and the 13 combined protein-coding genes, whereas only four lineages were observed when using the duplicate control regions. Most interestingly, each lineage had both copies of the control regions of the comprising individuals, indicating that the paralogous control regions were more similar than the orthologous sequences from the distinct lineages. This suggested the control regions had undergone concerted evolution. The Black-throated Tit has complex evolutionary history and needs further investigating the taxonomic status of these lineages, as well as the underlying evolutionary processes. Our findings call for more research on intraspecies mitogenomic variation.
