The historical biogeography of the Lumbricidae, the main Palearctic earthworm family, may be linked to the paleogeography of their putative ancestral range in Iberia–southeastern France–Corsica–Sardinia. Although molecular phylogenetics has recently been used to analyze most endemic genera in this area, the genus Kritodrilus has not yet been studied. The generotype Kritodrilus calarensis and other closely related species inhabit southeastern France. However, other species from the Iberian Peninsula (e.g., Kr. osellai) have been assigned to Kritodrilus, the same for the Vindobonic (Hungarian–Austrian–Czech–Slovakian) Dendrobaena mrazeki. In order to unravel the paleobiogeographic, evolutionary, and taxonomic significance of Kritodrilus, the aforementioned species (and three potential relatives) were sequenced for seven molecular markers. Molecular phylogenetic inference recovered a clade of French Kritodrilus (including Et. setusmontanus) closely related to the Northwestern Iberian Galiciandrilus and Compostelandrilus, the latter being a sister clade to the Vindobonic species (described as a new genus). Time‐calibrated phylogenetic inference estimated that these three clades diverged around 55 Ma. Ecological niche models for these clades were mainly influenced by the same environmental variables, but showed non‐overlapping highly suitable areas (except for Kritodrilus). Ancestral area reconstruction inferred the origin of the Lumbricidae in Corsica–Sardinia and the Iberian Peninsula, with eventual expansion eastwards toward France, Central Europe, and the Carpato‐Balkanic area. For Kritodrilus and its relatives, this expansion may have been contemporaneous with the Paleocene–Eocene thermal maximum. Later climatic changes may explain the strikingly disjunct ranges. This work highlights the evolutionary and biogeographic significance of these isolated earthworm lineages and the importance of their preservation.

“…Samplings and Studied Specimens. This study follows the methodology of Marchán et al [9,15], and the method description partially reproduces their wording. 15 specimens of six species of Lumbricidae (genera Allolobophora and Aporrectodea) were collected during two sampling surveys in southeastern and northeastern France in spring 2021 and autumn 2021, respectively.…”

“…Unfortunately, this has complicated evolutionary and biogeographic interpretations. The gradual implementation of molecular techniques has revolutionized the systematics of the genus, with the elevation of redefined Cernosvitovia [10] and Gatesona [9], previously considered subgenera of Allolobophora, to generic status. The present work has continued this trend by supporting the elevation of Panoniona to genus status and the assignment of two of the studied species to newly described genera.…”

“…chlorotica and other green pigmented species (Allolobophora dubiosa Örley, 1881, Allolobophora moebii Michaelsen, 1895, and Allolobophora molleri Rosa, 1889) formed a clade separated from the species assigned to the subgenus Allolobophora (Gatesona) Bouché, 1972 and to Allolobophora sensu lato (or Karpatodinariona Mršić and Šapkarev, 1988 and Serbiona Mršić and Šapkarev, 1988). Further molecular phylogenetic works cemented this separation by establishing the genus Gatesona [9] and by amending the genus Cernosvitovia Omodeo, 1956 to include several Balkanic species of Allolobophora sensu lato [10].…”

The taxonomy of earthworms has been riddled by instability, lack of systematically useful characters, and lax diagnoses of some genera. This has led to the use of some genera such as Allolobophora Eisen, 1874 as taxonomic wastebaskets, blurring their evolution and biogeographical history. The implementation of molecular techniques has revolutionized the systematics of the genus; however, some of its species have not been previously included in molecular phylogenetic analyses. Thus, the molecular markers COI, 16S, ND1, 12S, and 28S were sequenced for six endemic species including several taxa of Allolobophora and Aporrectodea Örely, 1885 (another related catch-all genus). Phylogenetic relationships determined by Bayesian inference and maximum likelihood analyses support the status of two of the six taxa examined (Allolobophora burgondiae Bouché, 1972 and Aporrectodea icterica Savigny, 1826) as part of Allolobophora sensu stricto and a presumed synonymy between Allolobophora and Heraclescolex Qiu and Bouché, 1998. Branch lengths and average pairwise genetic distances support the transfer of Allolobophora satchelli Bouché, 1972 to the genus Panoniona Mršić and Šapkarev, 1988 and the emergence of two new genera, Heraultia gen. nov. and Vosgesia gen. nov., endemic to France, hosting Allolobophora tiginosa Bouché, 1972 and Allolobophora zicsii Bouché, 1972, respectively. The aforementioned changes of status and the diagnosis for Heraultia and Vosgesia are presented. These results provided more evolutionarily and biogeographically coherent earthworm groups and highlighted that the Maghreb and the area around the Alps are potential key locations for the diversification of Allolobophora and several lineages of Lumbricidae.

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.
