“…The diversification of lineage B was also divided into three stages. The first stage (nodes 2, 3, 4 and 6 in Figure 4) occurred during the Wangkun Glaciation (MIS [16][17][18][19][20] in which Kunlun-Yellow River tectonic movement not only strongly uplifted the Tibetan Plateau but also the surrounding mountains. Coverage of the Tibetan Plateau by ice sheet peaked during MIS 16 at 18 times the present glacial coverage [91,92]; the mid-Pleistocene Revolution (~0.9 Ma), the most significant transition boundary, led to a significant drop in global temperature and extension of the ice sheet [92].…”

“…Phylogenetic analysis using different substitution rates for the CO1 gene was carried out to illustrate the differentiation and diffusion of earthworms [6,7,16]. Parthenogenesis, geological events, climatic changes and human beings are the factors that exert significant influence on the differentiation and diffusion of earthworms [16][17][18][19][20]. Additionally, phylogenetic analysis constructed by single gene or different gene combinations have led to an-increasing discovery of cryptic earthworm species [6,12,15,21,22], which are taxonomically important to earthworms.…”

“…In recent research, mitochondrial COI, COII, NDI, 12S rRNA and 16S rRNA have been widely used to study the phylogenetic evaluation, mitochondrial diversity and population genetic diversity of earthworm using multivariate concatenation [18,21,[23][24][25][26][27][28][29]. Complete mitochondrial genomes and genomic features of four pheretimoid earthworms (Amynthas longisiphonus, Amynthas corticis, Amynthas gracilis and Metaphire californica) revealed that mitochondrial ATP8 exhibited the highest evolutionary rate and the NADH gene was second to it [30].…”

Amynthas triastriatus (Oligochaete: Megascolecidae) is a widely distributed endemic species in Southern China. To shed light on the population genetic diversity and to elucidate the population differentiation and dispersal of A. triastriatus, a population genetic structure study was undertaken based on samples from 35 locations collected from 2010 to 2016. Two exclusive lineages within A. triastriatus—lineage A and lineage B—were revealed. Lineage A was mainly distributed at high altitudes while lineage B was mainly distributed at low altitudes in Southeast China. The genetic diversity indices indicated that the populations of A. triastriatus had a strong genetic structure and distinct dispersal histories underlying the haplogroups observed in this study. Combined with morphological differences, these results indicated a new cryptic subspecies of A. triastriatus. Lineage A was almost degenerated to parthenogenesis and lineage B had a trend to parthenogenesis, which suggested that parthenogenesis could be an internal factor that influenced the differentiation and dispersal of A. triastriatus. The divergence time estimates showed that A. triastriatus originated around Guangxi and Guangdong provinces and generated into two main lineages 2.97 Ma (95%: 2.17–3.15 Ma) at the time of Quaternary glaciation (2.58 Ma), which suggested that the Quaternary glaciation may have been one of main factors that promoted the colonization of A. triastriatus.

“…While important work has been conducted in other earthworm families (for example Rhinodrilidae (Benham 1890) [27,73], Megascolecidae (Rosa 1891) [41,45,74,75]), several families have received very little attention relative to the large percentage of earthworm diversity and occupied land masses they represent. Africa, South America, and North America display the strongest deficit of molecular phylogenetic research.…”

Earthworm systematics have been limited by the small number of taxonomically informative morphological characters and high levels of homoplasy in this group. However, molecular phylogenetic techniques have yielded significant improvements in earthworm taxonomy in the last 15 years. Several different approaches based on the use of different molecular markers, sequencing techniques, and compromises between specimen/taxon coverage and phylogenetic information have recently emerged (DNA barcoding, multigene phylogenetics, mitochondrial genome analysis, transcriptome analysis, targeted enrichment methods, and reduced representation techniques), providing solutions to different evolutionary questions regarding European earthworms. Molecular phylogenetics have led to significant advances being made in Lumbricidae systematics, such as the redefinition or discovery of new genera (Galiciandrilus, Compostelandrilus, Vindoboscolex, Castellodrilus), delimitation and revision of previously existing genera (Kritodrilus, Eophila, Zophoscolex, Bimastos), and changes to the status of subspecific taxa (such as the Allolobophorachaetophora complex). These approaches have enabled the identification of problems that can be resolved by molecular phylogenetics, including the revision of Aporrectodea, Allolobophora, Helodrilus, and Dendrobaena, as well as the examination of small taxa such as Perelia, Eumenescolex, and Iberoscolex. Similar advances have been made with the family Hormogastridae, in which integrative systematics have contributed to the description of several new species, including the delimitation of (formerly) cryptic species. At the family level, integrative systematics have provided a new genus system that better reflects the diversity and biogeography of these earthworms, and phylogenetic comparative methods provide insight into earthworm macroevolution. Despite these achievements, further research should be performed on the Tyrrhenian cryptic complexes, which are of special eco-evolutionary interest. These examples highlight the potential value of applying molecular phylogenetic techniques to other earthworm families, which are very diverse and occupy different terrestrial habitats across the world. The systematic implementation of such approaches should be encouraged among the different expert groups worldwide, with emphasis on collaboration and cooperation.

“…The K2P species divergences were reported, but were different for earthworm groups, for example, 13-15% for Allolobophora Eisen, 1874 (King et al 2008), 13.2% for Eisenia fetida/andrei complex (Römbke et al 2016), more than 14% in Octolasion lacteum Örley, 1885, Lumbricus rubellus Hoffmeister, 1843 (Klarica et al 2012), more than 18.7% in pheretimoid species (Chang et al 2008), 19.8% in the genus Lumbricus Linnaeus, 1758 (James et al 2010), 8.9-22.9% in the genus Pheretima Kinberg, 1867, 14.2-21.9% in the genus Amynthas Kinberg, 1867, 7.5-18.0% in the genus Pithemera Sim & Easton, 1972 and 11.7-21.0% in the genus Polypheretima Michaelsen, 1934(Aspe & James 2018. Recently, Jeratthitikul et al (2017) also calculated the average species distance of 20% for Amynthas and Metaphire species in Thailand.…”

Integrative taxonomy was employed to exploit the differences between the known Metaphire anomala (Michaelsen, 1907) and other specimens collected in Vietnam. The results brought to light two new species, namely Metaphire iranomala sp. nov. and Metaphire decemtheca sp. nov. The former is easily recognised by having male pores on xix and four pairs of spermathecal pores on 5/6/7/8/9 while the latter is distinguished by having five pairs of spermathecal pores on 4/5/6/7/8/9. The K2P distances of the fragment of the cytochrome c oxidase subunit I (COI) gene are 13.1% between M. iranomala sp. nov. and M. anomala (Michaelsen, 1907) and 18% between M. decemtheca sp. nov. and Metaphire grandiverticulata Nguyen & Lam, 2017. The intraspecific divergences are 1.5%–10.6% for M. iranomala sp. nov. and 2.1%–11.4% for M. decemtheca sp. nov.
