Here, we determined the nearly complete mitochondrial genome (mitogenome) of Chrysochares punctatus (Coleoptera: Chrysomelidae: Eumolpinae), an important insect pest on Apocynum venetum in Northwestern China. This mitogenome was 14,451 bp long, encoding 13 protein-coding genes (PCGs), 21 transfer RNA genes (tRNAs), and 2 ribosomal RNA genes. The C. punctatus mitogenome presented an A + T content of 75.11%, with a positive AT-skew (0.064) and a negative GC-skew (-0.192). Ten PCGs started with a typical ATN codon, whereas the remaining three PCGs started with AAC ( cox1 ) and TTG ( nad1 and nad2 ). All tRNAs had a typical secondary cloverleaf structure, except for trnS1 which lacked the dihydrouridine arm. Bayesian phylogenetic analysis based on the nucleotide sequences of 13 PCGs recovered a phylogeny within Chrysomelidae: (((Chrysomelinae + Galerucinae), (((Eumolpinae, Lamprosomatinae), Cassidinae), Criocerinae)), Bruchinae)., Competing Interests: The authors report no conflicts of interest.

In this study, we sequenced and annotated the nearly complete mitochondrial genome (mitogenome) of Sitona callosus (Coleoptera: Curculionidae). This mitogenome was 14,333 bp long and encoded 13 protein-coding genes, 19 transfer RNA genes (tRNAs), and two ribosomal RNA unit genes. Gene rearrangements were presented in a tRNA cluster of six tRNAs between nad3 and nad5 , i.e. the ancestral order ARNSEF was changed to be RNSAEF. All tRNAs had a typical secondary cloverleaf structure, except for trnS1 which lacked the dihydrouridine arm. The Bayesian phylogenetic tree of 11 Entiminae species based on the concatenated nucleotide sequences of 13 PCGs showed that S. callosus and S. lineatus formed a clade which was at the basal position in the Entiminae phylogeny., Competing Interests: The authors report no conflicts of interest.
