Abstract The family Pentatomidae, the largest within the superfamily Pentatomoidae, comprises about 5,000 species; many of which are economically important pests. Although the phylogeny of Pentatomidae species has been studied using various molecular markers, their phylogenetic relationships remain controversial. Recently, mitochondrial genomes (mitogenomes) have been extensively employed to examine the phylogenetics and evolution of different insects, and in this study, we sequenced complete/near-complete mitochondrial genomes from five shield bug species of Eurydema to gain a better understanding of phylogenetic relationships in the Pentatomidae. The five mitogenomes ranged in length from 15,500 to 16,752 bp and comprised 13 protein-coding genes (PCGs), 22 transfer RNAs (tRNAs), 2 ribosomal RNAs (rRNAs), and a control region. We compared mitogenomic characteristics of the Pentatomidae and constructed phylogenetic trees using Bayesian inference and maximum likelihood methods. Our results showed that gene arrangements, base composition, start/stop codons, gene overlaps, and RNA structures were conserved within the Pentatomidae and that congeneric species shared more characteristics. Saturation and heterogeneity analyses revealed that our PCGs and PCGRNA datasets were valid for phylogenetic analysis. Phylogenetic analyses showed consistent topologies based on BI and ML methods. These analyses strongly supported that Eurydema species belong to the tribe Strachiini, and formed a sister group with Pentatomini. The relationships among Eurydema species were shown to be consistent with their morphological features. (Strachiini + Pentatomini) was found to be a stable sibling of the clade comprising Cappaeini, Graphosomini, and Carpocorini. Furthermore, our results indicated that Graphosoma rubrolineatum (Heteroptera: Pentatomidae) belongs to the Pentatominae and not the Podopinae.

Complete Mitochondrial Genomes

The family Erotylidae belongs to the superfamily Cucujoidea, which are phytophagous and mycophagous. So far, only two representative complete mitochondrial (mt) genomes of Erotylidae have been sequenced. Mitochondrial genomes of Tritoma metasobrina, Neotriplax arisana, and Episcapha opaca, which all belong to the subfamily Erotylinae, were sequenced using next-generation sequencing technology to better understand the diversity of mt genomes of Erotylidae. A comparative mt genomic analysis was conducted on the three sequenced representatives of Erotylinae and Languriinae sp. (Languriinae). The size of the complete mt genome of the 4 species ranged from 15,581 bp to 16,502 bp in length, including 37 genes (13 protein-coding genes, 22 transfer RNAs, and 2 ribosomal RNAs) and the control region. The arrangements of their mt genomes are highly consistent with other Coleoptera species. The start codons of two PCGs (ND1 and ND5) and the stop codons of one PCG (ATP8) were illustrated differences between Languriinae sp. and the other three species. All tRNAs of these 4 species exhibited cloverleaf secondary structures except that the dihydorouridine (DHU) arm of tRNASer(AGN) was absent. The phylogenetic analyses using both Bayesian inference (BI) and maximum likelihood (ML) methods all supported that Erotylidae as monophyletic. Erotylinae was monophyletic being the sister group to Xenocelinae. Languriinae was closely related to ‘Erotylinae-Xenocelinae’. Our results recovered Languriinae nested within Erotylidae.

More studies are using mitochondrial genomes of insects to explore the sequence variability, evolutionary traits, monophyly of groups and phylogenetic relationships. Controversies remain on the classification of the Mileewinae and the phylogenetic relationships between Mileewinae and other subfamilies remain ambiguous. In this study, we present two newly completed mitogenomes of Mileewinae (Mileewa rufivena Cai and Kuoh 1997 and Ujna puerana Yang and Meng 2010) and conduct comparative mitogenomic analyses based on several different factors. These species have quite similar features, including their nucleotide content, codon usage of protein genes and the secondary structure of tRNA. Gene arrangement is identical and conserved, the same as the putative ancestral pattern of insects. All protein-coding genes of U. puerana began with the start codon ATN, while 5 Mileewa species had the abnormal initiation codon TTG in ND5 and ATP8. Moreover, M. rufivena had an intergenic spacer of 17 bp that could not be found in other mileewine species. Phylogenetic analysis based on three datasets (PCG123, PCG12 and AA) with two methods (maximum likelihood and Bayesian inference) recovered the Mileewinae as a monophyletic group with strong support values. All results in our study indicate that Mileewinae has a closer phylogenetic relationship to Typhlocybinae compared to Cicadellinae. Additionally, six species within Mileewini revealed the relationship (U. puerana + (M. ponta + (M. rufivena + M. alara) + (M. albovittata + M. margheritae))) in most of our phylogenetic trees. These results contribute to the study of the taxonomic status and phylogenetic relationships of Mileewinae.

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.

Typical Composition

In this study, the complete mitochondrial genomes (mitogenomes) of Hestina persimilis and Hestinalis nama (Nymphalidae: Apaturinae)were acquired. The mitogenomes of H. persimilis and H. nama are 15,252 bp and 15,208 bp in length, respectively. These two mitogenomes have the typical composition, including 37 genes and a control region. The start codons of the protein-coding genes (PCGs) in the two mitogenomes are the typical codon pattern ATN, exceptCGA in the cox1 gene. Twenty-one tRNA genes show a typical clover leaf structure, however, trnS1(AGN) lacks the dihydrouridine (DHU) stem. The secondary structures of rrnL and rrnS of two species were predicted, and there are several new stem loops near the 5’ of rrnL secondary structure. Based on comparative genomic analysis, four similar conservative structures can be found in the control regions of these two mitogenomes. The phylogenetic analyses were performed on mitogenomes of Nymphalidae. The phylogenetic trees show that the relationships among Nymphalidae are generally identical to previous studies, as follows: Libytheinae\Danainae + ((Calinaginae + Satyrinae) + Danainae\Libytheinae + ((Heliconiinae + Limenitidinae) + (Nymphalinae + (Apaturinae + Biblidinae)))). Hestinalisnama isapart fromHestina, andclosely related to Apatura, forming monophyly.

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 phylogenetic relationships between owls and nightjars are rather complex and controversial. To clarify these relationships, we determined the complete mitochondrial genomes of Glaucidium cuculoides, Otus scops, Glaucidium brodiei, Caprimulgus indicus, and Strix leptogrammica, and estimated phylogenetic trees based on the complete mitochondrial genomes and aligned sequences from closely related species that were obtained in GenBank. The complete mitochondrial genomes were 17392, 17317, 17549, 17536, and 16307 bp in length. All mitochondrial genomes contained 13 protein-coding genes, two rRNAs, 22 tRNAs, and a putative control region. All mitochondrial genomes except for that of Strix leptogrammica contained a pseudo-control region. ATG, GTG, and ATA are generally start codons, whereas TAA is the most frequent stop codon. All tRNAs in the new mtDNAs could be folded into canonical cloverleaf secondary structures except for tRNASer (AGY) and tRNALeu (CUN) , which missing the “DHU” arm. The phylogenetic relationships demonstrated that Strigiformes and Caprimulgiformes are independent orders, and Aegothelidae is a family within Caprimulgiformes. The results also revealed that Accipitriformes is an independent order, and Pandionidae and Sagittariidae are independent families. The results also supported that Apodiformes is polyphyletic, and hummingbirds (family Trochilidae) belong to Apodiformes. Piciformes was most distantly related to all other analyzed orders.

We determined the complete nucleotide sequence of the mitochondrial genome of Odorrana schmackeri (family Ranidae). The O. schmackeri mitogenome (18 302 bp) contained 13 protein-coding genes, 2 rRNA genes, 21 tRNA genes and a single control region (CR). In the new mitogenome, the distinctive feature is the loss of tRNA-His, which could be explained by a hypothesis of gene substitution. The new sequence data was used to assess the phylogenetic relationships among 23 ranid species mostly from China using maximum likelihood (ML) and Bayesian inference (BI). The phylogenetic analyses support two families (Ranidae, Dicroglossidae) for Chinese ranids. In Ranidae, we support the genus Amolops should be retained in the subfamily Raninae rather than in a distinct subfamily Amolopinae of its own. Meanwhile, the monophyly of the genus Odorrana was supported. Within Dicroglossidae, four tribes were well supported including Occidozygini, Dicroglossini, Limnonectini and Paini. More mitochondrial genomes and nuclear genes are required to decisively evaluate phylogenetic relationships of ranids.

Mitochondrial genomes (mitogenomes) are widely used in research studies on phylogenetic relationships and evolutionary history. Here, we sequenced and analyzed the mitogenome of the scentless plant bug Myrmus lateralis Hsiao, 1964 (Heteroptera, Rhopalidae). The complete 17,309 bp genome encoded 37 genes, including 13 protein-coding genes (PCGs), 22 transfer RNA (tRNA) genes, two ribosomal RNA (rRNA) genes, and a control region. The mitogenome revealed a high A+T content (75.8%), a positive AT-skew (0.092), and a negative GC-skew (–0.165). All 13 PCGs were found to start with ATN codons, except for cox1, in which TTG was the start codon. The Ka/Ks ratios of 13 PCGs were all lower than 1, indicating that purifying selection evolved in these genes. All tRNAs could be folded into the typical cloverleaf secondary structure, except for trnS1 and trnV, which lack dihydrouridine arms. Phylogenetic trees were constructed and analyzed based on the PCG+rRNA from 38 mitogenomes, using maximum likelihood and Bayesian inference methods, showed that M. lateralis and Chorosoma macilentum Stål, 1858 grouped together in the tribe Chorosomatini. In addition, Coreoidea and Pyrrhocoroidea were sister groups among the superfamilies of Trichophora, and Rhopalidae was a sister group to Alydidae + Coreidae.

Pentatomoidea is the largest superfamily of Pentatomomorpha; however, the phylogenetic relationships among pentatomoid families have been debated for a long time. In the present study, we gathered the mitogenomes of 55 species from eight common families (Acanthosomatidae, Cydnidae, Dinidoridae, Scutelleridae, Tessaratomidae, Plataspidae, Urostylididae and Pentatomidae), including 20 newly sequenced mitogenomes, and conducted comparative mitogenomic studies with an emphasis on the structures of non-coding regions. Heterogeneity in the base composition, and contrasting evolutionary rates were encountered among the mitogenomes in Pentatomoidea, especially in Urostylididae, which may lead to unstable phylogenetic topologies. When the family Urostylididae is excluded in taxa sampling or the third codon positions of protein coding genes are removed, phylogenetic analyses under site-homogenous models could provide more stable tree topologies. However, the relationships between families remained the same in all PhyloBayes analyses under the site-heterogeneous mixture model CAT + GTR with different datasets and were recovered as (Cydnidae + (((Tessaratomidae + Dinidoridae) + (Plataspidae + Scutelleridae)) + ((Acanthosomatidae + Urostylididae) + Pentatomidae)))). Our study showed that data optimizing strategies after heterogeneity assessments based on denser sampling and the use of site-heterogeneous mixture models are essential for further analysis of the phylogenetic relationships of Pentatomoidea.
