It is endemic to the Montseny Massif (Catalan Pre-Coastal Range) in northeast Spain.

[2] When handled, Montseny brook newts release a whitish, noxious, sticky, and very odorous skin secretion.

[2] Its natural habitats are oligotrophic, cold (under 15 °C) fast running rivers; it seems to be a strictly aquatic species.

The drying out of mountain streams, human alteration of its original habitat and the global warming are threats to this species.

Because of this, the International Union for Conservation of Nature (IUCN) lists it as "critically endangered".
