“…Both nad6 (0.083) and atp6 (0.102) show slightly higher Ka/Ks values than most of other PCGs, indicating they are likely to be under a relaxed purifying selection. The atp8 with the extremely higher (Ka/Ks = 0.614) values may be an outlier, similar results were observed in the previous study [62]. The mitochondrial gene cox1 has been one of the commonly used markers and a powerful tool for identifying species and inferring the phylogenetic relationship due to it is easy amplification.…”

To understand mitogenome characteristics and reveal phylogenetic relationships of the genus Ostrinia, including several notorious pests of great importance for crops, we sequenced the complete mitogenomes of four species: Ostrinia furnacalis (Guenée, 1854), Ostrinia nubilalis (Hübner, 1796), Ostrinia scapulalis (Walker, 1859) and Ostrinia zealis (Guenée, 1854). Results indicate that the four mitogenomes-O. furnacalis, O. nubilalis, O. scapulalis, and O. zealis-are 15,245, 15,248, 15,311, and 15,208 bp in size, respectively. All four mitogenomes are comprised of 37 encoded genes and a control region. All 13 protein-coding genes (PCGs) initiate with ATN and terminate with TAN, with the exception of cox1 that starts with CGA, and cox1, cox2, and nad5 that terminate with an incomplete codon T. All transfer RNA genes (tRNAs) present the typical clover-leaf secondary structure except for the trnS1 (AGN) gene. There are some conserved structural elements in the control region. Our analyses indicate that nad6 and atp6 exhibit higher evolution rates compared to other PCGs. Phylogenetic analyses based on mitogenomes using both maximum likelihood (ML) and Bayesian inference (BI) methods revealed the relationship (O. palustralis + (O. penitalis + (O. zealis + (O. furnacalis + (O. nubilalis + O. scapulalis))))) within Ostrinia. Insects 2020, 11, 232 2 of 15East Asia, and Northwestern Africa. Within this third species group, three subgroups are recognized according to the differences in male mid-tibia. The first subgroup contains four species including O. nubilalis and O. furnacalis with smaller mid-tibia and lacking any groove or scales. The second subgroup includes two species, namely O. kurentzovi (Mutuura and Munroe, 1970) and O. narynensis (Mutuura and Munroe, 1970), with a moderately dilated tibia and a fringe of enlarged curved scales. The third subgroup consists of four species, including O. scapulalis and O. zealis, possessing a strongly dilated tibia and massive scales in the groove. Mutuura and Munroe (1970) stated that the three species groups within the genus Ostrinia are monophyletic and indicated that O. penitalis is the most primitive species. The second group was defined as monophyletic because the members share potential synapomorphies in male genitalia [2]. The third species group has been intensively studied on the basis of their morphology, pheromones, and DNA sequence. Based on the complexity of the male tibia, Mutuura and Munroe (1970) considered that the species with the smallest tibia is the most primitive, then the species with the medium tibia are intermediate, and finally, the species with the large tibia and massive tuft are the most derived.Frolov (1981, 1984) stated that the variation in the male mid-tibia was determined by two alleles. The Mt and Mt + were two alleles located on autosomes and controlled the size of the mid-tibia, while i and i + were two alleles located on Z-sex-linked chromosomes and controlled the groove appearance. Mt/Mt + and i/i + follow a Mendelian inheritance pattern ...

“…Although fragment of 648 bp of the gene cox1 is often considered as a universal barcode for species identification in animals [50], it is the least variable gene in Panorpidae and has a relatively lower ratio of Ka/Ks among the PCGs in these 19 mitogenomes. Given the resolution power of cox1 is proved to be sufficiently low, other genes that have fast evolutionary rates and higher ratio of Ka/Ks and are of sufficiently large size should be proposed as potential barcode candidates [39,51,52]. Based on our present study, nad2 and nad6 may be chosen as potential DNA markers for future population genetics and species delimitation studies in Panorpidae.…”

“…The mismatched pairs in stems of some tRNAs exist in all 17 newly sequenced scorpionfly mitogenomes. This mismatched pair phenomenon exists widely in the insect [36][37][38][39]. These mismatched pairs would simply represent unusual pairings [40] or be corrected by the RNA editing process [41].…”

“…Nucleotide diversity analyses are useful for identifying high nucleotide divergence regions, which are crucial for designing species-specific markers [39,49], especially in the taxa of highly variable morphological characters. Although fragment of 648 bp of the gene cox1 is often considered as a universal barcode for species identification in animals [50], it is the least variable gene in Panorpidae and has a relatively lower ratio of Ka/Ks among the PCGs in these 19 mitogenomes.…”

Background: Mitochondrial genomes play a significant role in reconstructing phylogenetic relationships and revealing molecular evolution in insects. However, only two species of Panorpidae have been documented for mitochondrial genomes in Mecoptera to date.Results: We obtained complete mitochondrial genomes of 17 species of Panorpidae. The results show that the complete mitogenome sequences of Panorpidae all contain 37 genes (13 protein-coding genes (PCGs), two rRNAs, 22 tRNAs) and one control region. The mitogenomes exhibit a strong AT bias. The AT-skew can either be slightly positive or slightly negative, while the GC-skew is usually negative. The 22 tRNA genes can fold into a common cloverleaf secondary structure except trnS1. The sliding window and genetic distance analyses demonstrate highly variable nucleotide diversity among the 13 protein-coding genes, with comparatively low evolutionary rate of cox1, cox2 and nad1, and high variability of nad2 and nad6. The phylogeny of Panorpidae can be presented as (Neopanorpa + Furcatopanorpa) + (Dicerapanorpa + (Panorpa debilis + (Sinopanorpa + (Cerapanorpa + Panorpa)))).Conclusions: Our analyses indicate that the genes nad2 and nad6 can be regarded as potential markers for population genetics and species delimitation in Panorpidae. Panorpa is reconfirmed a paraphyletic group.

The family Hesperiidae (skippers) is one of the most speciose families in the butterflies and consists of about 567 genera and more than 4,000 species around the world (Warren et al., 2008), accounting for one-fifth of the world's butterfly species, though the number is far underestimated. The higher classification of the family had mainly followed Evans (Evans, 1943(Evans, , 1949(Evans, , 1951 until Warren et al.inferred the phylogenetic relationship from molecular (three loci) and morphological data of 196 genera (Warren et al., 2008(Warren et al., , 2009. The latest molecular study of 250 hesperiid species from all over the world (Li, Cong, et al., 2019) and its supplementary study (Zhang et al., 2019) showed that the family Hesperiidae should be classified into 12 subfamilies, based on the timing of divergence, with the relationship of (Coeliadinae + (Euschemoninae + ((Eudaminae + (Tagia dinae + (Pyrrhopyginae +Pyrginae))) + (Katreinae + (Chamundinae
