The complete mitochondrial genome of Downesia tarsata (Coleoptera: Chrysomelidae: Cassidinae)

Abstract

Downesia species are leaf-mining beetles mainly feed on Poaceae plants in the tropical and subtropical areas in Asia. In this study, we firstly sequenced and reported the complete mitochondrial genome for the genus. The complete mitogenome of Downesia tarsata is 18,557 bp in length, including 13 protein-coding genes (PCG), 22 transfer RNA (tRNA), two ribosomal RNA (rRNA), and one AT-rich region. Phylogenomic analysis indicated that D. tarsata is closely related to Agonita chinensis, and the two species belong to the same tribe of Gonophorini. The complete mitochondrial genome of D. tarsata could help clarify the phylogenetic relationship among Cassidinae species.
