To provide molecular markers for population genetic analysis of the flea beetle Agasicles hygrophila, we determined its mitochondrial genome (mitogenome) for the first time. The mitogenome of A. hygrophila was 15 917 bp in length with an AT content of 75.15%. It had the typical set of 13 protein-coding genes (PCGs), 22 tRNA genes, two rRNA genes, and an AT-rich control region. Compared with the ancestral mitogenome of insects, no gene rearrangement occurred in A. hygrophila. Incomplete stop codons were present in PCGs of A. hygrophila. All tRNA genes except for trnS(AGN) could form the typical clover-leaf secondary structures. The phylogenetic analysis indicated that A. hygrophila was close to other species belonging to the same family of Chrysomelidae.
