In a fast-changing environment, it is important to keep track of biodiversity. In Mexico, new herpetofauna is described every year. Vocalisations can portray ecological and evolutionary characteristics for better understanding of species. Here, we lay out the current state of knowledge on advertisement calls of Mexican anurans, as well as the publication trends and the use of metadata through an exhaustive literature review and bibliometric analysis. We obtained 174 documents with advertisement call descriptions of 58.4% of Mexican anuran species published between 1940–2021. We identified that most of the species with call descriptions are distributed in the Neotropics and belong to endemic and endangered categories. Anuran call descriptions in publications are frequently accompanied by associated data such as relative humidity, call frequency, or recording format. The mean number of recorded characteristics per description was 12.568 (of 38). Although almost half of the Mexican species have associated advertisement call descriptions, we identified several knowledge gaps, particularly in the degree of information that each description contains. Furthermore, most of the identified studies were performed outside of Mexico by foreign researchers, despite the high level of anuran endemism in the country. We highlight the need for more detailed descriptions published by Mexican researchers.
