Abstract
In its general pattern the sexual behaviour of Triturus montandoni most resembles that of Triturus helveticus. The courtship consists of three phases: orientation, static display and retreat display, followed by a spermatophore transfer phase. During display the male performs three tail movements: the fan, the whip, and the wave. The relative frequencies of tail movements and the duration of fanning bouts are the main difference between T montandoni, T. helveticus, and T. vulgaris. The phylogenetic relationships between these three species are discussed.
