Characterization of the complete mitochondrial genome of Hydrotaea spinigera (Diptera: Muscidae) with phylogenetic implications

Hydrotaea spinigera Stein is a muscid species with high forensic importance. To further supplement the genome-level features of related species, the complete mitochondrial genome of H. spinigera is amplified, sequenced, annotated, analyzed, and compared with 13 other species of the family Muscidae. This mitogenome is 15,517 bp in length, with a standard set of 13 protein-coding genes (PCGs), 22 transfer RNA (tRNA) genes, two ribosomal RNA (rRNA) genes, and a typical non-coding control region. The gene organization, base composition, and secondary structures of tRNA genes of this mitogenome are similar to other dipteran species. Phylogenetic analyses based on all the mitochondrial PCGs and rRNA genes for 14 muscid and one outgroup taxa are performed using Bayesian inference (BI) and maximum likelihood (ML) analysis. The inferred trees indicate that the Muscidae, the subfamily Muscinae, and the tribes Azeliini and Reinwardtiini are monophyletic, whereas the monophyly of the subfamily Azeliinae and the tribe Muscini is not supported.
