We obtained acoustic data from analyses of audio recordings gathered from personal and museum collections for 67 species and from the bibliography for 5 species. We obtained morphometric data for 67 glassfrog species from the literature, and for 11 species from fellow researchers. We compiled the predominant calling site of each species from the literature (72 species) and complemented it with field observations provided by fellow researchers. We compiled parental care (i.e., prolonged attendance) data from Delia et al. (2017). See Escalona et al., Journal of Evolutionary Biology, for more details
