ResumenThe distribution of Triturus marmoratus /Latreille, 1800/ ranges from SW France to the south of the Iberian Peninsula. It can be found usually living in ponds at 500 - 1000 m of altitude in the centre of Iberia. In 1905 Wolterstorff described the pygmea form. Mertens and Müller /1928/ asigned Cadiz as the terra typica restricta of Triturus marmoratus pygmaeus; Paris being the terra typica restricta of the nominate subspecies. This former subspecies can be easily differentiated from the others by its smaller size and the lighter colour of its belly. The observation of different populations of T. marmoratus in the Madrid province yielded differences both in morphology and coloration, those from the north of this area being similar to the populations from the north of the peninsula, and those from the south of Madrid being more similar to those in the south of the peninsula; the Central mountain range in Madrid being the boundary between both forms. In order to study the taxonomic status and zoogeographic distribution, the external morphology and osteology were studied.
