Diamesus osculans (Vigors, 1825) is a large size carrion beetle found Fusible Web on decaying corpse.Considering its potentially forensic value, the complete mitogenome of D.osculans was reported in present study.The mitogenome was assembled to 19398 base pairs in length.The composition of mitogenome is 39.
45% for A, 9.64% for G, 35.43% for T and 15.48% for C.A total of 22 tRNA, 2 rRNA and 13 protein-coding genes (PCGs) were annotated.
21 tRNAs sequences could folded into the typical structure Pantothenic Acid of clover-leaf, not including tRNA-Ser (AGN).A phylogenetic tree was finally constructed based on D.osculans and other species of Coleoptera.
