Who is who? An integrative taxonomic revision of Iberus carthaginiensis (Rossmässler, 1853) (Gastropoda: Helicidae) in southeastern Spain

The taxonomically poorly known Iberian genus of land snails Iberus exhibits high levels of endemicity, often confined to small regions.An example is a small snail restricted to the southeastern coastal area of the Iberian Peninsula which had been known as Iberus carthaginiensis until a new species, I. calaensis, was assigned to its westernmost populations.Since then, the taxonomic name I. carthaginiensis has been solely applicable to the former eastern populations.The findings of a taxonomic integrative revision of I. carthaginiensis by combining geographical, morphological and phylogenetic evidence reveal that the populations of the current eastern distribution for I. carthaginiensis correspond to a new species, not previously sequenced, which is named I. punicus sp.n.Likewise, the molecular results obtained from samples collected within the type locality of I. calaensis confirm that this taxon is a junior synonym of I. carthaginiensis.Therefore, I. carthaginiensis remains restricted to the western populations of the traditional distribution assigned to this species, and I. calaensis is invalidated.
