“…Therefore, the southern (A) S. satunini haplogroup represents the authentic mitochondrial DNA of this species, as hypothesised earlier by Bannikova and Lebedev (2010) and Mackiewicz et al (2017). It is interesting to note that, according to Stakheev et al (2020), S. araneus and S. satunini occur parapatrically in the interfluve of the Don and Kuban rivers, with occasional hybridisation (one hybrid genotype has been found).…”

In the present study, we reconstruct phylogenetic relationships within the chromosomally variable Sorex araneus species group based on 20 nuclear loci and the mitochondrial cyt b gene. In the species tree, Nearctic S. arcticus represents the earliest offshoot of the group followed by Holarctic S. tundrensis and Siberian S. daphaenodon. Five other species distributed mostly in Europe form a wellsupported clade. Coding regions showed stronger phylogenetic signal than introns. The results suggest a high incidence of reticulation in the evolution of the group. The authentic mitochondrial lineage of the Iberian shrew S. granarius was found to be close phylogenetically to S. coronatus, which confirms that some populations of the Iberian shrew S. granarius were introgressed from S. araneus.Footprints of deeper reticulations are revealed for the first time, indicating the potential hybrid origin of the S. arcticus and S. coronatus lineages. Ancient hybridisations are hypothesised to be the source of discordance between molecular-and karyotype-based phylogenetic reconstructions.
