The complete mitochondrial genome of a Chinese stag beetle, Prismognathus prossi, was generated using the Illumina next-generation sequencing. The mitogenome sequence is 15,984 bp in length, the nucleotide composition isA 36.6%, C17.5%, T34.3% andG11.6%with theAT-content of 70.9%. The sequence has similar features with other reported insectmitogenomes, consisting of 13 proteincoding genes (PCGs), 22 transferRNAgenes, tworibosomalRNAsand a control region. All of the protein-coding genes start with the typicalATNinitiation codon except for COI. Maximum Likelihood (ML) and Bayesian Inference (BI) indicated that P. prossi share an affinity with Lucanus mazama, Lucanus fortunei and Cyclommatus vitalisi.

AbstractIn this study, we analyzed the complete mitochondrial genome (mitogenome) of Speiredonia retorta, which is a pest and a member of the Lepidoptera order. In total, the S. retorta mitogenome was found to contain 15,652 base pairs encoding 13 protein-coding genes (PCGs), 22 tRNAs, 2 rRNAs, as well as an adenine (A) + thymine (T)-rich region. These findings were consistent with the mitogenome composition of other lepidopterans, as we identified all 13 PCGs beginning at ATN codons. We also found that 11 PCGs terminated with canonical stop codons, whereas cox2 and nad4 exhibited incomplete termination codons. By analyzing the mitogenome of S. retorta using Bayesian inference (BI) and maximum likelihood (ML) models, we were able to further confirm that this species is a member of the Erebidae family.

Pentatoma rufipes (Linnaeus, 1758) is an important agroforestry pest widely distributed in the Palaearctic region. In this study, we sequence and annotate the complete mitochondrial genome of P. rufipes and reconstruct the phylogenetic trees for Pentatomoidea using existing data for eight families published in the National Center for Biotechnology Information database. The mitogenome of P. rufipes is 15,887-bp-long, comprising 13 protein-coding genes, 22 transfer RNA genes, two ribosomal RNA genes, and a control region, with an A+T content of 77.7%. The genome structure, gene order, nucleotide composition, and codon usage of the mitogenome of P. rufipes were consistent with those of typical Hemiptera insects. Among the protein-coding genes of Pentatomoidea, the evolutionary rate of ATP8 was the fastest, and COX1 was found to be the most conservative gene in the superfamily. Substitution saturation assessment indicated that neither transition nor transversion substitutions were saturated in the analyzed datasets. Phylogenetic analysis using the Bayesian inference method showed that P. rufipes belonged to Pentatomidae. The node support values based on the dataset concatenated from protein-coding and RNA genes were the highest. Our results enrich the mitochondrial genome database of Pentatomoidea and provide a reference for further studies of phylogenetic systematics.

Azygia hwangtsiyui (Trematoda, Azygiidae), a neglected parasite of predatory fishes, is little-known in terms of its molecular epidemiology, population ecology and phylogenetic study. In the present study, the complete mitochondrial genome of A. hwangtsiyui was sequenced and characterized: it is a 13,973 bp circular DNA molecule and encodes 36 genes (12 protein-coding genes, 22 transfer RNA genes, two ribosomal RNA genes) as well as two non-coding regions. The A+T content of the A. hwangtsiyui mitogenome is 59.6% and displays a remarkable bias in nucleotide composition with a negative AT skew (–0.437) and a positive GC skew (0.408). Phylogenetic analysis based on concatenated amino acid sequences of twelve protein-coding genes reveals that A. hwangtsiyui is placed in a separate clade, suggesting that it has no close relationship with any other trematode family. This is the first characterization of the A. hwangtsiyui mitogenome, and the first reported mitogenome of the family Azygiidae. These novel datasets of the A. hwangtsiyui mt genome represent a meaningful resource for the development of mitochondrial markers for the identification, diagnostics, taxonomy, homology and phylogenetic relationships of trematodes.

Background The stag beetle Lucanus cervus (Coleoptera: Lucanidae) is widely distributed in Europe. Habitat loss and fragmentation has led to significant reductions in numbers of this species. In this study, we sequenced the complete mitochondrial genome of L. cervus and reconstructed phylogenetic relationships among Lucanidae using complete mitochondrial genome sequences. Methods Raw data sequences were generated by the next generation sequencing using Illumina platform from genomic DNA of L. cervus. The mitochondrial genome was assembled by IDBA and annotated by MITOS. The aligned sequences of mitochondrial genes were partitioned using PartitionFinder 2. Phylogenetic relationships among 19 stag beetle species were constructed using Maximum Likelihood (ML) method implemented in IQ-TREE web server and Bayesian method implemented in PhyloBayes MPI 1.5a. Three scarab beetles were used as outgroups. Results The complete mitochondrial genome of L. cervus is 20,109 bp in length, comprising 13 protein-coding genes, 22 transfer RNA genes, two ribosomal RNAs and a control region. The A + T content is 69.93% for the majority strand. All protein-coding genes start with the typical ATN initiation codons except for cox1, which uses AAT. Phylogenetic analyses based on ML and Bayesian methods shown consistent topologies among Lucanidae.

The Pygopodidae comprise an enigmatic group of legless lizards endemic to the Australo-Papuan region. Here we present the first complete mitochondrial genome for a member of this family, Aprasia parapulchella, from Australia. The mitochondrial genome of A. parapulchella is 16 528 base pairs long and contains 13 protein-coding genes, 22 tRNA genes, two rRNA genes and the control region, conforming to the typical vertebrate gene order. The overall mitochondrial nucleotide composition is 31.7% A, 24.5% T, 30.5% C and 13.2% G. This corresponds to a total A+T content of 56.3%, which is similar to that of other squamate lizard genomes.

In this study, the complete mitochondrial genomes (mitogenomes) of two hoverfly species of Korinchia angustiabdomena (Huo, Ren, and Zheng) and Volucella nigricans Coquillett (Diptera: Syrphidae) were determined and analyzed. The circular mitogenomes were 16,473 bp in K. angustiabdomena (GenBank No. MK870078) and 15,724 bp in V. nigricans (GenBank No. MK870079). Two newly sequenced mitogenomes both contained 37 genes, and the gene order was similar with other syrphine species. All the protein-coding genes (PCGs) were started with the standard ATN codons; and most of PCGs were terminated with a TAA stop codon, while ND1 in K. angustiabdomena ended with a TAG codon, and ND5 terminated with truncated T stop codons in both species. The phylogenetic relationship between K. angustiabdomena and V. nigricans with related lineages was reconstructed using Bayesian inference and Maximum-likelihood analyses. The monophyly of each family considered within Muscomorpha was confirmed by the clades in the phylogenetic tree, and superfamily of the Oestroidea (Calliphoridae, Sarcophagidae, and Oestridae) was unexpectedly found to be a paraphyletic group based on our selected data. This mitogenome information for K. angustiabdomena and V. nigricans could facilitate future studies of evolutionarily related insects.

Haplaxius crudus Van Duzee is a pest of various economically important palms due to its ability to transmit lethal yellowing, a fatal phytoplasma infection. It is also the putative vector of lethal bronzing in Florida, another lethal phytoplasma disease causing significant economic losses. To date, no mitochondrial genomes for species in the family Cixiidae are sequenced. In this study, the complete mitochondrial genome of H. crudus was sequenced, assembled, and annotated from PacBio Sequel II long sequencing reads using the University of Florida’s HiPerGator. The mitogenome of H. crudus is 15,848 bp long and encodes 37 mitochondrial genes (including 13 protein-coding genes (PCGs), 22 tRNAs, and 2 rRNAs) in addition to a putative noncoding internal control region. The nucleotide composition of H. crudus is asymmetric with a bias toward A/T (44.8 %A, 13.4 %C, 8.5 %G, and 33.3 %T). Protein-coding genes (PCGs) possess the standard invertebrate mitochondrial start codons with few exceptions while the gene content and order of the H. crudus mitogenome is highly similar to most completely sequenced insect mitochondrial genomes. Phylogenetic analysis based on the entire mitogenome shows H. crudus resolving closely to Delphacidae, the accepted sister taxon of Cixiidae. These data provide a useful resource for developing novel primer sets that could aid in either phylogenetic studies or population genetic studies. As more full mitogenomes become available in the future for other planthopper species, more robust phylogenies can be constructed, giving more accurate perspectives on the evolutionary relationships within this fascinating and economically important group of insects.

AbstractBackgroundThe Lepidoptera is one of the largest insect orders. Previous studies on the evolution of Lepidoptera did not confidently place butterflies, and many relationships among superfamilies in the megadiverse clade Ditrysia remain largely uncertain. Here, we generated a molecular dataset with 78 species of lepidopterian insects, including a new complete mitochondrial genome (mitogenome) sequences of the Golden Birdwing Butterfly, Troides aeacus, which was listed in appendix II of CITES.MethodsBased on the concatenated nucleotide sequences of 13 protein-coding genes, we constructed phylogenetic trees with Bayesian Inference (BI) and Maximum Likelihood (ML) methods, and calculated the divergence times of Lepidoptera.ResultsMonophyly of the Papilionoidea including skippers (Hesperiidae) is strongly supported by a high bootstrap value. Butterflies were placed sister to the remaining obtectomeran Lepidoptera, and the latter was grouped with high bootstrap supports. Additionally, Papilionidae probably diverged from the group (Hesperiidae + (Nymphalidae + Pieridae)) at 102.65 Mya, the Early Cretaceous. T. aeacus and the Golden kaiserihind Teinopalpus aureus diverged in the Cretaceous of 85.32 Mya. The age of Papilionoidea indicates that the primary break up of Gondwana may have an effect on the current distributions of butterflies.
