The complete mitochondrial genome of Sarcophaga gracilior (Diptera: Sarcophagidae)

Sarcophaga gracilior Chen, 1975 (Diptera: Sarcophagidae) plays a significant role in epidemiology and medicine. In this study, we first report the complete mitochondrial genome (mitogenome) of S. gracilior. This mitogenome was 15,534 bp in length (GenBank No. MW531675), comprising 13 protein-coding genes (PCGs), two ribosomal RNAs (rRNAs), 22 transfer RNAs (tRNAs), and a non-coding control region. The arrangement of genes was identical to that of ancestral metazoan. Nucleotide composition revealed a strong A + T bias, accounting for 76.7% (A 39.6%, G 9.3%, C 14.0%, T 37.1%). The phylogenetic relationships indicated that the species of S. gracilior emerged as sister to Sarcophaga melanura. This study provides important mitochondrial data for further studying evolutionary relationships and species identification of flesh flies.
