Thanks @loarie , I suggest to follow ASW.
Also the Taxonomic Committee of the Societas Europaea Herpetologica does not consider it a valid species (https://brill.com/view/journals/amre/aop/article-10.1163-15685381-bja10010/article-10.1163-15685381-bja10010.xml ): "In addition to mtDNA sequences, Vences et al. (2014) used sequences from thirteen nuclear loci to improve our understanding of the history of the genus Salamandra. Their nuclear data suggest that Salamandra salamandra contains several deeply divergent lineages whose monophyly relative to S. algira received weak support, although this requires confirmation. Based on mitochondrial data the subspecies longirostris is sister to all other S. salamandra lineages. However, nuclear genes place it with the subspecies morenica. The discordance between mtDNA and nuclear genes may result from past introgression and admixture processes. Furthermore, a clade comprising the subspecies fastuosa, bernardezi (including populations attributed to the subspecies alfredschmidti, whose validity was rejected, as it is phylogenetically nested within several subclades of bernardezi; Beukema et al., 2016) and gigliolii is recovered with strong support. While additional data are clearly needed, this suggests a high amount of evolutionary divergence within S. salamandra, and the existence of more than one species within S. salamandra cannot yet be fully ruled out."
