ABSTRACT
The genus Proceratophrys Miranda-Ribeiro, 1920, frogs from the family Odontophrynidae Lynch, currently contains 41 nominal species with poorly resolved phylogenetic relationships (Frost 2019; Mângia et al. 2018). Molecular data from 15 and 18 Proceratophrys species support the monophyletic hypothesis of the genus (Teixeira-Jr et al. 2012; Dias et al. 2013; respectively) but do not fully resolve the phylogenetic relationship among the species. Currently, there are advertisement call parameters provided for 31 species of Proceratophrys in the literature (Ferreira et al. 2016; Andrade et al. 2018; Mângia et al. 2018; Nascimento et al. 2019). The Proceratophrys advertisement call is composed of pulsed notes, amplitude modulation, short to medium duration calls (0.05-4 s) and only one note in almost all species (see Nascimento et al. 2019 for details). Considering the importance of bioacoustics for taxonomy (Köhler et al. 2017), further descriptions of advertisement calls for the genus could also improve our understanding of the species' relationships.

Dendropsophus branneri is a small treefrog largely distributed throughout the Tropical Atlantic and Caatinga morphoclimatic domains (see Ab'Sáber 1977 for morphoclimatic domains), from northeastern to southeastern Brazil [Lutz 1973, Frost 2014; see Zina et al. 2014 for taxonomic comments on D. minusculus (Rivero, 1971) and D. branneri]. This species is currently placed in the D. microcephalus species group according to Bastos & Pombal (1996) and Faivovich et al. (2005). The D. microcephalus group comprises 36 species (Frost 2014), 14 of which have known tadpoles. Here, we describe the external morphology and color patterns of the previously unknown tadpole of D. branneri.

The treefrog genus Dendropsophus Fitzinger comprises 95 species, with geographic distribution from northern Argentina and Uruguay north through tropical South and Central America to tropical southern Mexico (Frost 2014). Dendropsophus studerae was included in the D. microcephalus clade by Faivovich et al. (2005), which currently consists of 39 species (Frost 2014). The species that most resembles D. studerae is D. bipunctatus (Spix), as already stated in the original description of the former (Carvalho-e-Silva et al. 2003). Thus far, Dendropsophus studerae was only known from its type locality, in the municipality of Quebrangulo (09º19'08"S, 36º28'16"W), State of Alagoas, northeastern Brazil. The original description of the species also included data on its eggs, tadpole (oral disc and external morphology) and some natural history information of adults and larvae, but its advertisement call remains undescribed.
