Abstract
The genus Gastrotheca Fitzinger, 1843 currently harbors 75 species (Frost 2020). These marsupial frogs have a broad latitudinal distribution range in Central and South America, from Costa Rica southward to Argentina (Duellman 2015). The advertisement call features as the pulse structure, call duration, and repetition pulse rate are used by researchers to recognize the species of Gastrotheca (Duellman 2015). The availability of call descriptions is also crucial for recognizing these species with secretive life habits and implementing long-term passive acoustic monitoring programs (Vaira et al. 2011; Akmentins et al. 2014).
