The Neotropical monotypic genus Macrogenioglottus was described by Carvalho (1946), having M. alipioi as the type species. Macrogenioglottus was considered as a juniorsynonym of Odontophrynus by Lynch (1971) but latter the same author reversed his decision (Lynch, 1973). Silva et al. (2003) discussed the phylogenetic position of this taxon relative to the familiesBufonidae and Leptodactylidae, suggested a distant relationship to Bufonidae, and retained this genus in Leptodactylidae (Frost 2007). Today the genus Macrogenioglottus is considered valid and included inthe family Cycloramphidae (Frost 2007).

Macrogenioglottus alipioi (Figure 1) was described by Carvalho (1946) based on specimens from Ilhéus, state of Bahia, Brazil. According to Abravaya andJackson (1978), the sonogram of the advertisement call of M. alipioi is similar to that of Odontophrynus americanus and the tadpoles of Macrogenioglottus are similar to those of Odontophrynus, having thesame tooth row formula and similar arrangement of labial papillae. They differ, however, in the positions of the spiracle and of the vent. According to Abravaya and Jackson (1978) a review of thetaxonomic history of M. alipioi suggests a close relationship between Macrogenioglottus and Odontophrynus.
