The complete mitochondrial genome of Scythropus yasumatsui (Coleoptera: Curculionidae)

The complete mitochondrial genome sequence of Scythropus yasumatsui (Coleoptera: Curculionidae) was determined by using an Illumina platform. The circular genome was 16,472 bp in length and contained 22 transfer RNA genes (tRNAs), two ribosomal RNA genes (rRNAs), 13 protein-coding genes (PCGs), and one control region. The nucleotide composition was significantly biased (A, G, C, and T was 39.74%, 10.11%, 15.41%, and 34.74%, respectively) with A + T contents of 74.49%. All PCGs were initiated with standard ATN (ATG/ATT) codons. While 10 PCGs were terminated with TAA, two PCGs were terminated with TAG (cytb and nad1), and nad5 was terminated with an incomplete stop codon TA. All tRNAs were predicted to contain typical cloverleaf secondary structures except trnS1. The phylogenetic analysis of the concatenated nucleotide sequences of 13 PCGs from 12 Curculionidae species was performed by using MrBayes 3.1.2. The results indicated that S. yasumatsui was more closely related to Naupactus xanthographus than to other species.
