Abstract (EN): Morphological and genetic data for the Iberian golden- striped salamander, Chioglossa lusitanica, demonstrate the existence of two groups with southern and northern ranges, connected by a zone of intergradation in central Portugal. Because reproductive isolation between them is incomplete we consider the groups to be subspecies. The type locality of C. lusitanica ( Bucaco near Lousa) is situated inside the mixed zone. This necessitates identification of the nominotypical subspecies. We sequenced a fragment of mitochondrial DNA from one of the species' syntypes and we determined what position over a latitudinal transect maximizes the morphological discrimination between the groups. Both approaches indicate that C. lusitanica from Bucaco represents the southern subspecies. A new subspecies of C. lusitanica is described from a northern locality ( Valongo near Porto in northwestern Portugal). A lectotype is designated for Chioglossa lusitanica.
