Reporting the characteristics of the advertisement call in anuran species is an essential aspect of their taxonomic characterization. The aim of the present study was to describe the advertisement call of Melanophryniscus paraguayensis in the Central department of Paraguay, an endemic and threatened species in the country. The advertisement call of M. paraguayensis is a complex call, featuring different note types, tonal and multi-pulsed, with a duration of 0.4–6.4 s, and a dominant frequency of 2239–2928 Hz. The data obtained were compared with available descriptions of advertisement calls from both the Melanophryniscus stelzneri group and other species within the genus Melanophryniscus.

La descripción de las características del canto de advertencia de los anuros forma parte de la caracterización
taxonómica de las especies. El objetivo del presente estudio fue describir el canto de advertencia de Melanophryniscus paraguayensis, una especie endémica y amenazada de Uruguay, en el departamento Central de este país. El canto de advertencia de M. paraguayensis es un canto complejo con dos tipos de notas, tonales y multi-pulsadas, que tiene una duración de 0.4–6.4 s y una frecuencia dominante de 2239-2928 Hz. Los datos obtenidos se compararon con las descripciones disponibles de cantos de advertencia de especies del grupo Melanophryniscus stelzneri como de otras especies del género Melanophryniscus.
