Coccotorus beijingensis Lin et Li, 1990 belongs to Coleoptera, Curculionidae, Curculioninae, Anthonomini. It is a herbivorous insect that damages Celtis bungeana Blume (Ulmaceae) by affecting branch growth. The mitochondrial genome of C. beijingensis was sequenced and annotated to better identify C. beijingensis and related species. The total length of the C. beijingensis mitochondrial genome was 17,071 bp, contained 37 typical genes (13 protein-coding genes, two ribosomal RNA genes, 22 transfer RNA genes) and two control regions (total length: 2,292 bp). Mitochondrial genome composition, nucleotide composition and codon usage are similar to those of other sequenced Curculionidae mitogenomes. All protein-coding genes initiated with ATN and TTG codons and ended with TAA, TAG or incomplete stop codons (TA, T). In addition, analyses of pairwise genetic distances between individual PCGs in Curculionidae species showed that ATP8 was the least conserved gene, while COI was the most conserved. Twenty-one transfer RNAs had typical cloverleaf structures, while trnS1 lacked dihydrouridine (DHU) arms. ML and BI analyses, based on 13 PCGs and two rRNAs from ten species of Curculionidae, strongly support the relationships between C. beijingensis and species of the genus Anthonomus: ((An. eugenii+ An. rubi) + C. beijingensis + (An. pomorum+ An. rectirostris)) (BS = 100; PP = 1). Our phylogenetic analyses could mean that the genus Coccotorus should be sunk under Anthonomus, but more taxon sampling is needed to verify this result.
mitochondrial genome, Coccotorus beijingensis, phylogenetic analysis
Mitochondria are important organelles involved in metabolism, apoptosis and life cycle of insect cells (
Coccotorus beijingensis Lin et Li, 1990 is widely distributed in northern China. It is harmful to the shoots of Celtis bungeana Blume (Urticales, Ulmaceae), causing tissue proliferation and formation of galls, affecting the growth of branches and even causing dead branches (
The genus Anthonomus contains over 700 species, of which some are considered agricultural pests (
Adult specimens of Coccotorus beijingensis were collected from Celtis bungeana in Shimen Mountain Forest Park, Jining City, Shandong Province, China (
Genomic DNA of all samples was sent to Personalbio Inc. (Shanghai, China) for library construction and next-generation sequencing (NGS). One library (Insert size of 400 bp) was prepared for each DNA sample using the TruSeqTM DNA Sample Prep Kit (Illumina, USA). All constructed libraries were then sequenced as 150 bp paired-end on a full run (2 × 150 PE) using the Illumina NovaSeq platform. Reads for species library have been deposited in the BioProject (PRJNA903367). The paired ends reads were de novo assembled using Novoplasty 3.7 (
A total of eleven mitogenomes from Curculionidae were used for the phylogenetic analyses (Table

Circular map of the mitogenome of C. beijingensis. The outer circle shows the gene map of C. beijingensis and the genes outside the map are coded on the major strand (J-strand), whereas the genes on the inside of the map are coded on the minor strand (N-strand). Genes are represented by different colour blocks.
The mitochondrial genome length measured in this study was 17,071 bp and the change in the size of the control region was the main source of the change in the mitochondrial genome length (Table
The mitochondrial genome of Coccotorus beijingensis showed a strong AT bias in nucleotide content, with 73.6% AT content in the whole genome, the lowest AT content in PCGs (72.4%) and the highest AT content in tRNAs (76.8%) (Table

The total size of the 13 PCGs of C. beijingensis was 11,095 bp, accounting for 64.99% of the entire mitochondrial genome. Most of the 13 PCGs (COⅠ-Ⅲ, ND2-6, ND4L, ATP6 and ATP8) used ATN (ATA\ATT\ATG) as the start codon and only ND1 used TTG as the start codon. All PCGs stopped with TAA/G or their incomplete form T-. The incomplete termination codon single T- can be completed by post-transcriptional polyadenylation (
Pairwise genetic distances in single PCG amongst eleven species in Curculionidae are shown in Fig.
Genetic distances amongst individual PCGs. Each boxplot represents the P-distance for 13 individual genes in eleven species in Curculionidae. The box plot presents the minimum and maximum values at the ends of the whiskers, the 25th and 75th percentiles at the ends of a box, the median as a horizontal line in the box at the 50th percentile value, hollow square represent the average and solid diamond as outliers.
Coccotorus beijingensis had 22 typical tRNAs, ranging in length from 60 bp (trnR) to 70 bp (trnK) (Table
The control region regulates the replication and transcription of mtDNA (
Based on ML and BI analyses of 13 PCGs and rRNAs nucleotide data, we reconstructed the phylogenetic relationships of 11 Curculionidae species, including C. beijingensis. Both phylogenetic trees had congruent topological structure and all branches were strongly supported (Fig.
ML and BI phylogenetic trees for C. beijingensis, based on the nucleotide sequence data of 13 PCGs and two rRNAs from C. beijingensis and other ten species belonging to three subfamilies in the family of Curculionidae. Bootstrap support values (BS) and Bayesian posterior probabilities (PP) are indicated on the branch.
Reads for species library have been deposited in the BioProject (PRJNA903367).
