Characterization of the mitochondrial genome of Arge bella sp. nov. (Hymenoptera: Argidae)
We describe Arge bella sp. nov., a large and beautiful species of Argidae from south China, and report its mitochondrial genome based on high-throughput sequencing data. We present the gene order, nucleotide composition of protein-coding genes (PCGs), and the secondary structures of tRNA genes. The nearly complete mitochondrial genome of A. bella has a length of 15,576 bp (GenBank accession NO. MF287761) and a typical set of 37 genes (22 tRNAs, 13 PCGs, and 2 rRNAs). Three tRNAs are rearranged in the A. bella mitochondrial genome as compared to the ancestral type in insects: trnM and trnQ are shuffled, while trnW is translocated from the trnW-trnC-trnY cluster to a location downstream of trnI. All PCGs are initiated by ATN codons, and terminated with TAA, TA or T as a stop codon. All tRNAs have a typical cloverleaf secondary structure, except for trnS1. H821 of rrnS and H976 of rrnL are redundant. A phylogenetic analysis based on mitogenome sequences of A. bella, 21 other symphytan species, 2 apocritan representatives, and 4 outgroup taxa support the placement of Argidae as sister to the Pergidae within the symphytan superfamily Tenthredinoidea.
