A subspecies of marbled newt (Triturus marmoratus) in the Iberian Peninsula newly resolved from congruent nuclear and mitochondrial dna data

Newts of the genus Triturus are one such group with undiscovered yet taxonomically relevant variation, as shown by the recent description of new (sub)species of pygmy newts (T. pygmaeus, T. rudolfi). The marbled newt, Triturus marmoratus, shows an equally deep and geographically coherent spatial-genetic diversification. It is here shown that a northern and a southern group are characterized by different mitochondrial dna profiles and are also differentiated in morphometry and colouration pattern. With no firm evidence for selection against intermediate genotypes, the southern group is described at the subspecies level, as T. marmoratus harmannis ssp. nov. Leer más.
