“…The authors applied different approaches to genetic structure identification and species delimitation together with geometric morphometrics analysis ( Fig. 1), finding congruent support for three species-level genetic clusters (hereafter cluster A, B and C), which comprised one or more of the six previously identified lineages as described in Daniel F. Marchán et al, (2017). The well-supported putative species identified in Carpetania demanded a full, detailed taxonomic description: several authors have stressed the necessity of going a step further from cryptic species identification (Jörger & Schrödl, 2013;Wang et al, 2016).…”

“…These parameters were obtained from the populations function (STACKS2 package) summary files. Correlation between SNP-based genetic distances and F ST and the same parameters obtained from cytochrome C oxidase 1 sequences (Daniel F. Marchán et al, 2017) was tested through a Mantel test in the R package vegan (Dixon, 2003).…”

“…Diagnostic SNP positions were identified using function nucDiag in the R package spider (Brown et al, 2012) and parsed to the corresponding contig using the Carpetania elisae transcriptome after it was functionally annotated with eggNOG-mapper (Huerta-Cepas et al, 2017). Diagnostic nucleotidic positions were also identified in the molecular markers COI, 16S-tRNAs, 28S and H3 retrieved from (Daniel F. Marchán et al, 2017) following the same method.…”

“…One of the most studied cryptic species groups among these animals is the former Hormogaster elisae Álvarez, 1977, recognized as the genus Carpetania after Daniel Fernández Marchán et al, (2018). Six highly divergent cryptic lineages were identified using Sanger-sequenced mitochondrial and nuclear markers (Daniel F. Marchán, Fernández, de Sosa, Díaz Cosín, & Novo, 2017), but their description was precluded by the absence of clear-cut limits between the putative species. Quantitative differences in the distal end of genital chaetae were discovered between those cryptic lineages through geometric morphometrics (Daniel F. Marchán, Sánchez, et al, 2016), hinting a possible pseudocryptic status for the identified lineages.…”

AbstractResearch on cryptic species complexes has reached a consensus on the necessity of integrating multiple sources of evidence. Low-coverage genomic scan techniques like Genotyping-by-Sequencing (GBS) have proven useful to study these groups. Both integrative taxonomy and genome-wide single nucleotide polymorphism (SNP) data remain to be widely applied to earthworms, an animal group with widespread presence of cryptic diversity. The genus Carpetania (formerly the Hormogaster elisae species complex) was found to contain six deeply divergent genetic lineages and some inconspicuous morphological differentiation based in a handful of Sanger-sequenced markers. Marchán et al. (submitted) delimited three well supported species-level clades on the basis of a genomewide SNP dataset and geometric morphometric analyses, highlighting the necessity of a formal taxonomic description of these taxa. In this work, further analyses are applied to the SNP data and a thorough morphological study is performed in order to provide an integrative description of two new species and to redescribe Carpetania elisae. Species-specific SNPs are identified and used as diagnostic characters, and genome-wide and cytochrome oxidase C subunit 1 (COI) genetic distances are compared finding a strong correlation between them. The taxonomic description of these three cryptic species provides a useful tool to include them effectively in ecological studies and biodiversity conservation actions.

Corsica and Sardinia are amongst the largest islands of the Western Mediterranean. Their complex geological history included belonging to the European–Iberian continental margin (close to current-day Catalonia and Provence) and varying degrees of isolation for the last 30 million years, leading to peculiar, highly endemic faunas and floras. This is especially true for their earthworm faunas, which include endemic species of several Lumbricoidea genera and the endemic family (or subfamily) Diporodrilidae. Only three species have been described for the morphologically unique Diporodrilus, but there exists evidence for wide morphological variability within them and the existence of several species-level genetic lineages within Corsica. This work aimed to investigate the genetic diversity and phylogenetic relationships between the genetic lineages of Diporodrilus from Corsica and Sardinia (based on the sequences of 5 mito-nuclear markers), to perform an integrative systematics revision combining species delimitation techniques and morphological data, and to obtain a time-calibrated phylogeny of Diporodrilus and other Corso-Sardinian Lumbricoidea. Within 15 populations of the morphospecies Diporodrilus omodeoi and Diporodrilus pilosus across Corsica and Sardinia, 10 species-level genetic lineages were detected. Phylogenetic independence, high genetic divergence and morphological differences provided the support for the description of five new pseudocryptic species: Diporodrilus rotundus sp. nov., Di. jorgei sp. nov., Di. minor sp. nov., Di. meridionalis sp. nov. and Di. telti sp. nov. Time-calibrated phylogenetic inference estimated the age for genus Diporodrilus at 65.9 Mya; even if other Corso-Sardinian genera were significantly younger, all of them presented deep divergences predating the break-off of the microplate from the continent. The almost threefold increase in the known diversity of Diporodrilus stresses the need for comprehensive earthworm diversity inventories in both Sardinia and Corsica, and for studies on their ecological role and conservation status. The close correspondence between some geological and cladogenetic events suggest that the distribution of Corso-Sardinian earthworms could be used to inform standing geological controversies.
