“…Resolving this problem may require further assessment involving other assumed members of the superfamily Onychiuroidea, such as Odontellidae Massoud, 1967 andPachytullbergiidae Stach, 1954. Moreover, the deep genetic divergence indicated by relatively long branch lengths supported the separation between Tullbergiidae and Onychiuridae, and indicated these two apparently similar groups may have undergone different selective pressures affecting the mitochondrial genomes [43]. From an eco-morphological aspect, although both groups are usually considered as euedaphic lifeform [3,70], most tullbergiids have a smaller body size and more slender body shape than onychiurids.…”

Collembola are a basal group of Hexapoda renowned for both unique morphological characters and significant ecological roles. However, a robust and plausible phylogenetic relationship between its deeply divergent lineages has yet to be achieved. We carried out a mitophylogenomic study based on a so far the most comprehensive mitochondrial genome dataset. Our data matrix contained mitogenomes of 31 species from almost all major families of all four orders, with 16 mitogenomes newly sequenced and annotated. We compared the linear arrangements of genes along mitochondria across species. Then we conducted 13 analyses each under a different combination of character coding, partitioning scheme and heterotachy models, and assessed their performance in phylogenetic inference. Several hypothetical tree topologies were also tested. Mitogenomic structure comparison revealed that most species share the same gene order of putative ancestral pancrustacean pattern, while seven species from Onychiuridae, Poduridae and Symphypleona bear different levels of gene rearrangements, indicating phylogenetic signals. Tomoceroidea was robustly recovered for the first time in the presence of all its families and subfamilies. Monophyly of Onychiuroidea was supported using unpartitioned models alleviating LBA. Paronellidae was revealed polyphyletic with two subfamilies inserted independently into Entomobryidae. Although Entomobryomorpha has not been well supported, more than half of the analyses obtained convincing topologies by placing Tomoceroidea within or near remaining Entomobryomorpha. The relationship between elongate-shaped and sphericalshaped collembolans still remained ambiguous, but Neelipleona tend to occupy the basal position in most trees. This study showed that mitochondrial genomes could provide important information for reconstructing the relationships among Collembola when suitable analytical approaches are implemented. Of all the data refining and model selecting schemes used in this study, the combination of nucleotide sequences, partitioning model and

“…Several specimens of D. saundersi and N. murinus were morphologically identified and stored at -80 • C until molecular analyses. DNA extraction, amplification, sequencing, and assembly/annotation of the genome closely followed [27]. PAUP* (v 4.0, Sinauer Associates, Sunderland, Massachusetts) [28] was used to calculate base frequencies along each entire genome, for concatenated PCGs oriented on the same strand and for each codon position separately.…”

Collembola (springtails) are an early diverging class of apterygotes, and mark the first substantial radiation of hexapods on land. Despite extensive work, the relationships between major collembolan lineages are still debated and, apart from the Early Devonian fossil Rhyniella praecursor, which demonstrates their antiquity, the time frame of springtail evolution is unknown. In this study, we sequence two new mitochondrial genomes and reanalyze all known Collembola mt-genomes, including selected metagenomic data, to produce an improved phylogenetic hypothesis for the group, develop a tentative time frame for their differentiation, and provide a comprehensive overview of gene order diversity. Our analyses support most taxonomically recognized entities. We find support for an Entomobryomorpha + Symphypleona clade, while the position of Neelipleona could not be assessed with confidence. A Silurian time frame for their basal diversification is recovered, with an indication that divergence times may be fairly old overall. The distribution of mitochondrial gene order indicates the pancrustacean arrangement as plesiomorphic and dominant in the group, with the exception of the family Onychiuridae. We distinguished multiple instances of different arrangements in individual genomes or small clusters. We further discuss the opportunities and drawbacks associated with the inclusion of metagenomic data in a classic study on mitochondrial genome diversity.

“…In the course of our study of Collembola of Changbai Mountains (northeast China), we collected this species and sequenced its mitogenome. Mitogenomic studies perform well in constructing phylogenetic relationships of Collembola (Carapelli et al 2014(Carapelli et al , 2019Leo et al 2019). However, it has been little used at the intra-family level because of limited available mitogenomic data in public datasets.…”

The complete mitogenome of Metisotoma macnamarai (Folsom 1918) (Collembola, Isotomidae), a member of obligatory predaceous genus Metisotoma Maynard, 1951, was sequenced. It has a length of 15,177 bp, comprising 13 protein-coding genes, 22 tRNAs, and 2 rRNAs. The mitogenome has the following base composition: A ¼ 37.1%, T ¼ 33.3%, G ¼ 11.8%, and C ¼ 17.4%. Phylogenetic analysis using maximum likelihood (ML) indicates that M. macnamarai clusters as sister taxon to the genus Isotomurus, with high statistical support.
