We sequenced the complete mitochondrial genome (mitogenome) of a stonefly, Amphinemura claviloba (Wu, 1973), of the family Nemouridae (Insecta: Plecoptera). The mitogenome was 15,707 bp long and contained typical 37 genes with an A+T content of 68.5%. All protein-coding genes (PCGs) use standard initiation codons (methionine and isoleucine), except ND1 and ND5 which starts with TTG and GTG, respectively. Two of the 13 PCGs harbor the incomplete termination codon. All tRNA genes have typical clover secondary structures, except the dihydrouridine (DHU) arm of tRNASer(AGN) forms a simple loop. Secondary structure models of the ribosomal RNA genes of A. claviloba are similar to those proposed for other insects. We also found some structural elements in the control region, such as tandem repeats, poly-C stretch and microsatellite-like elements, etc. Phylogenetic analyses showed the clades for the Nemoura, Amphinemura, and (Mesonemoura + Sphaeronemoura + Indonemoura + Protonemura) are well supported in a polytomy.

Zicrona caerulea (Linnaeus, 1758) is a cosmopolitan stink bug species, which belongs to the predatory subfamily Asopinae. In this study, the complete mitochondrial genome of Zicrona caerulea from Shanxi, China was sequenced for the first time, using next generation sequencing. The mitogenome was found to be 15,479 bp in length. It contained 13 protein-coding genes, two rRNA genes, 22 tRNA genes and a typical control region. This research revealed an overall A+T content of 77.14%. All tRNA genes had a clover-leaf structure except for trnS1, which lacks a dihydrouridine (DHU) arm; and for trnV, the DHU arm forms a simple loop. The lengths of rrnS and rrnL were 797 bp and 1,285 bp, respectively. Because of a shortage in tandem repeats, the A+T-rich region was 644 bp in length. Phylogenetic relationships based on these mitogenomes, using Bayesian inference and Maximum likelihood methods, showed that Zicrona caerulea belongs to Asopinae. The monophyly of families of the Pentatomoidea is supported, albeit limited taxon sampling.

Of the roughly 400 species of Perlidae in the world, most species are widely distributed in the northern hemisphere, but a few can be found in South Africa and South America. There are only five species in the genus Flavoperla of the family Perlidae in China. To gain a better understanding of the architecture and evolution of mitochondrial genome in Flavoperla, the entire mitochondrial genome (mitogenome) of a Chinese Flavoperla biocellata Chu, 1929 from family Perlidae (Insecta: Plecoptera) was sequenced. The 15,805-bp long mitochondrial genome of F. biocellata contained 37 genes, including 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs), two ribosomal RNA genes (rRNAs) and a putative control region (CR). The gene arrangement of F. biocellata was identical with that of other stoneflies and with the fly Drosophila yakuba. Most PCGs of F. biocellata used the standard ATN start codons and complete TAN termination codons. Twenty-one of the 22 tRNA genes exhibited cloverleaf secondary structures, but the dihydrouridine (DHU) arm of trnSer (AGN) was completely reduced. Phylogenetic analyses with both Bayesian inference (BI) and maximum likelihood methods (ML) generated similar topology, both supporting the monophyly of all stonefly families and the infraorder Systellognatha. The phylogenetic analysis based on mitochondrial genomic data from 30 stonefly species recovered a well-supported tree resolving higher-level relationships within Plecoptera. The northern hemisphere suborder Arctoperlaria divided into two groups, Euholognatha and Systellognatha. The southern hemisphere suborder Antarctoperlaria formed two clades: Eustheniidae+Diamphipnoidae and Austroperlidae+ Gripopterygidae; consistent with relationships proposed based on morphology. The final relationships within Plecoptera were recovered as (((Perlidae+(Perlodidae+Chloroperlidae))+(Pteronarcyidae+(Peltoperlidae+Styloperlidae))) +(Taeniopterygidae+(Capniidae+(Nemouridae+Notonemouridae))))+ (Gripopterygoidae+Eusthenioidae).

The 15528 bp long complete mitochondrial genome (mt-genome) of a flat bug, Aradacanthia heissi Bai, Zhang & Cai,was determined. The entire genome contains typical 37 genes with an A+T content of 74.7%. The gene arrangement dif-fers from that of Drosophila yakuba Burla which is considered the representative ground pattern for insect mt-genomes,as the results of inversion of tRNAIle - tRNAGln and tRNACys - tRNATrp . All protein-coding genes (PCGs) use standard initia-tion codons (methionine and isoleucine), except COI which starts with TTG. Three of the 13 PCGs harbor the incompletetermination codon. Meanwhile, opposite CG-skew tendency occurs on the nucleotide composition and codon usage andthis tendency is also reflected on the J-strand and N-strand of PCGs. All tRNAs can fold into classic clover-leaf structure,whereas the dihydrouridine (DHU) arm of tRNASer(AGN) forms a simple loop. Secondary structure models of the ribosomalRNA genes of A. heissi are predicted and similar to those proposed for other insects. The control region is located betweensrRNA and tRNAGln with 81.5% A+T content, which was the most A+T-rich region of the mt-genome and four 68 bp tan-dem repeat units were found in this region. Phylogenetic analyses of available species of Pentatomomorpha showed Ara-doidea and the Trichophora are sister groups that bolstered the mainstream hypothesis, and provide the evidence for the feasibility of mt-genome data to resolve relationships at the subfamily level in Aradidae.

We present the complete mitochondrial (mt) genome sequence of the stonefly, Styloperla spinicercia Wu, 1935 (Plecoptera: Styloperlidae), the type species of the genus Styloperla and the first complete mt genome for the family Styloperlidae. The genome is circular, 16,129 base pairs long, has an A+T content of 70.7%, and contains 37 genes including the large and small ribosomal RNA (rRNA) subunits, 13 protein coding genes (PCGs), 22 tRNA genes and a large non-coding region (CR). All of the PCGs use the standard initiation codon ATN except ND1 and ND5, which start with TTG and GTG. Twelve of the PCGs stop with conventional terminal codons TAA and TAG, except ND5 which shows an incomplete terminator signal T. All tRNAs have the classic clover-leaf structures with the dihydrouridine (DHU) arm of tRNASer(AGN) forming a simple loop. Secondary structures of the two ribosomal RNAs are presented with reference to previous models. The structural elements and the variable numbers of tandem repeats are described within the control region. Phylogenetic analyses using both Bayesian (BI) and Maximum Likelihood (ML) methods support the previous hypotheses regarding family level relationships within the Pteronarcyoidea. The genetic distance calculated based on 13 PCGs and two rRNAs between Styloperla sp. and S. spinicercia is provided and interspecific divergence is discussed.

In this study, we report the complete mitochondrial genome of Harpalus sinicus (occasionally named as the Chinese ground beetle) which is the first mitochondrial genome for Harpalus. The mitogenome is 16,521 bp in length, comprising 37 genes, and a control region. The A + T content of the mitogenome is as high as 80.6%. A mitochondrial origins of light-strand replication (OL)-like region is found firstly in the insect mitogenome, which can form a stem-loop hairpin structure. Thirteen protein-coding genes (PCGs) share high homology, and all of them are under purifying selection. All tRNA genes (tRNAs) can be folded into the classic cloverleaf secondary structures except tRNA-Ser (GCU), which lacks a dihydrouridine (DHU) stem. The secondary structure of two ribosomal RNA genes (rRNAs) is predicted based on previous insect models. Twelve types of tandem repeats and two stem-loop structures are detected in the control region, and two stem-loop structures may be involved in the initiation of replication and transcription. Additionally, phylogenetic analyses based on mitogenomes suggest that Harpalus is an independent lineage in Carabidae, and is closely related to four genera (Abax, Amara, Stomis, and Pterostichus). In general, this study provides meaningful genetic information for Harpalus sinicus and new insights into the phylogenetic relationships within the Carabidae.

In the present study, we sequenced the complete mitochondrial genome (mitogenome) of Agrius convolvuli (Lepidoptera: Sphingidae) and compared it with previously sequenced mitogenomes of lepidopteran species. The mitogenome was a circular molecule, 15 349 base pairs (bp) long, containing 37 genes. The order and orientation of genes in the A. convolvuli mitogenome were similar to those in sequenced mitogenomes of other lepidopterans. All 13 protein-coding genes (PCGs) were initiated by ATN codons, except for the cytochrome c oxidase subunit 1 (cox1) gene, which seemed to be initiated by the codon CGA, as observed in other lepidopterans. Three of the 13 PCGs had the incomplete termination codon T, while the remainder terminated with TAA. Additionally, the codon distributions of the 13 PCGs revealed that Asn, Ile, Leu2, Lys, Phe, and Tyr were the most frequently used codon families. All transfer RNAs were folded into the expected cloverleaf structure except for tRNASer(AGN), which lacked a stable dihydrouridine arm. The length of the adenine (A) + thymine (T)-rich region was 331 bp. This region included the motif ATAGA followed by a 19-bp poly-T stretch and a microsatellite-like (TA)8 element next to the motif ATTTA. Phylogenetic analyses (maximum likelihood and Bayesian methods) showed that A. convolvuli belongs to the family Sphingidae.

To date, only one mitochondrial genome (mitogenome) in the Eumeninae has been reported in the world and this is the first report in China. The mitogenome ofO.a.aterrimusis 17 972 bp long, and contains 38 genes, including 13 protein coding genes (PCGs), 23 tRNA genes, two rRNA genes, a long non-coding region (NCR), and a control region (CR). The mitogenome has 79.43% A + T content, its 13 PCGs use ATN as the initiation codon except forcox1using TTG, and nine genes used complete translation termination TAA and four genes have incomplete stop codon T (cox2,cox3,nad4, andcytb). Twenty-two of 23 tRNAs can form the typical cloverleaf secondary structure except fortrnS1. The CR is 1 078 bp long with 84.69% A+T content, comprising 28 bp tandem repeat sequences and 13 bp T-strech. There are two gene rearrangements which are an extratrnM2located betweentrnQandnad2and thetrnL2in the upstream ofnad1. Within all rearrangements of these mitogenomes reported in the family Vespidae, the translocation betweentrnS1andtrnEgenes only appears in Vespinae, and the translocation oftrnYin Polistinae and Vespinae. The absent codons of 13 PCGs in Polistinae are more than those both in Vespinae and Eumeninae in the family Vespidae. The study reports the complete mitogenome ofO.a.aterrimus, compares the characteristics and construct phylogenetic relationships of the mitogenomes in the family Vespidae.

Millipedes of the family Xystodesmidae (Polydesmida) are often host to several symbiotic mite species, but very little work has been done to identify these acarines or to understand their relationship to the millipedes. In an attempt to better understand these associations, mites found on xystodesmid millipedes, a group for which a species phylogeny has been proposed, were collected in the Appalachian Mountains of Kentucky, Virginia, Tennessee and North Carolina. Mites in the genera Stylochyrus Canestrini & Canestrini, 1882 (Mesostigmata: Ologamasidae) and Schwiebea Oudemans, 1916 (Sarcoptiformes: Acaridae) were prevalent among millipedes in the genera Apheloria Chamberlin, 1921, Appalachioria Marek & Bond, 2006, Boraria Chamberlin, 1943, Brachoria Chamberlin, 1939, Dixioria Chamberlin, 1947, Nannaria Chamberlin, 1918, Pleuroloma Rafinesque, 1820, Prionogonus Shelley, 1982, Rudiloria Causey, 1955 and Sigmoria Chamberlin, 1939. Of the mite taxa collected, the species Stylochyrus rarior (Berlese, 1916) was found on the greatest number of sampled millipede taxa. To enhance future coevolutionary studies of xystodesmid millipedes and their mite symbionts, the complete mitochondrial genome of S. rarior associated with the millipede genus Apheloria (Polydesmida: Xystodesmidae) was sequenced. The genome is 14 899 nucleotides in length, has all the typical genes of an arthropod mitochondrion, differs in gene arrangement from that of the ancestral arthropod, and has a gene order that is unique among mites and ticks. The major difference in S. rarior is the placement of the protein-coding gene nad1, which is positioned between the rRNA gene 12S and the protein-coding gene nad2 (tRNA genes and non-coding regions excluded). There are also two non-coding control regions within this mitochondrial genome.

Cloverleaf Structure

The nearly complete mitochondrial genome of Coridius chinensis (Dallas) is reported in this study. The mitogenome is a double-stranded circular molecule of more than 14,648 bp in length with an A+T content of 75.1%. It encoded 37 genes as in other insect mtDNAs, including 13 protein-coding genes (PCGs), 22 tRNA genes, 2 rRNA genes and a control region (unsuccessful sequencing), and the gene order is the same as most other known heteropteran mitogenomes. All of the 22 transfer RNAs can be folded into the typical cloverleaf structure except tRNASer(AGN), which can only form a simple loop at the site of dihydrouridine (DHU) arm as known in other metazoans. The secondary structures of the large and small ribosomal RNAs of C. chinensis are similar to other presented insects. The rrnL consisted of six structural domains and 40 helices, and the rrnS consisted of three structural domains and 26 helices. Nine PCGs are initiated with the standard initiation codons (ATN), while ND6 and ND1 use GTG, and COI and ATP8 use TTG. All PCGs stopped with TAA/TAG termination codons except the COII terminated with a single T residue. Asymmetry in the nucleotide composition between J-strand and N-strand was observed in this mitogenome.

To explore the mitogenome characteristics and shed light on the phylogenetic relationships and molecular evolution of Drabescini species, we sequenced and analyzed the complete mitochondrial genome of two species including Drabescus ineffectus and Roxasellana stellata. The complete mitogenomes of D. ineffectus and R. stellata are circular, closed and double-stranded molecules with a total length of 15744 bp and 15361 bp, respectively. These two newly sequenced mitogenomes contain the typical 37 genes. Most protein-coding genes (PCGs) began with the start codon ATN and terminated with the terminal codon TAA or TAG, with an exception of a special initiation codon of ND5, which started with TTG, and an incomplete stop codon T-- was found in the Cytb, COX2, ND1 and ND4. All tRNAs could be folded into the canonical cloverleaf secondary structure except for the trnS1, which lacks the DHU arm and is replaced by a simple loop. The multiple tandem repeat units were found in A + T-control region. The sliding window, Ka/Ks and genetic distance analyses indicated that the ATP8 presents a high variability and fast evolutionary rate compared to other PCGs. Phylogenetic analyses based on three different datasets (PCG123, PCG12R and AA) using both Bayesian inference (BI) and maximum likelihood (ML) methods showed strong support for the monophyly of Drabescini.
