The complete mitogenome of Curculiochinensis (Chevrolat, 1878) (Coleoptera: Curculionidae: Curculioninae)

The mitogenome of Curculiochinensis (Chevrolat, 1878) was sequenced and annotated to better identify C.chinensis and related species. The mitogenome is 18,680 bp in length, includes the 37 typical mitochondrial genes (13 protein-coding genes, two ribosomal RNA genes and 22 transfer RNA genes) and two control regions (total length: 3,879 bp). Mitogenome organisation, nucleotide composition and codon usage are similar to the previously sequenced Curculio mitogenomes. All 13 protein-coding genes use ATN or TTG as start codon and end with TAA/G or incomplete stop codons (single T-). Twenty-one transfer RNA genes have the typical clover-leaf structure, while the dihydrouridine (DHU) arm of trnS1 is missing. In Curculio mitogenomes, the size of the control region is highly variable. Both ML and BI analyses, based on the 13 PCGs and two rRNAs from six species of Curculioninae, strongly supported the monophyly of Curculio. In Curculio, the relationships amongst included species were inferred as ((C.chinensis + Curculio. sp.) + (Curculiodavidi + Curculioelephas)), with C.chinensis and C. sp. forming a clade (BS = 100; PP = 1).
