Craugastor pygmaeus is the smallest anuran within its genus and probably the smallest known anuran from Mexico. In this study, it is described the advertisement call of the C. pygmaeus from the population of La Cienega in Flora and Fauna Protection Area Sierra de Quila, Jalisco, Mexico. The call consists of the repetition of a short whistle without modulated frequency and irregular call repetition. It was distinguished that advertisement calls show individual variation in the dominant frequency, which suggests that C. pygmaeus has an individual spectral signature.
