“…Odontophrynus toledoi is restricted to the Atlantic Forest of Serra da Mantiqueira, while O. juquinha is restricted to the Serra do Espinhaço savanna. Both mountain ranges are notable for their high number of endemic amphibian species (Cruz & Feio 2007;Silva et al 2018). Another evidence is that, although the raw acoustic S2.…”

“…The highest lands in this region are in the Mantiqueira mountain range, which runs for about 900 km along the borders of the states of São Paulo, Rio de Janeiro, Espírito Santo, and Minas Gerais, in southeastern Brazil (Peixoto et al 2020). The Mantiqueira mountain range harbors one of the most diverse anuran fauna in the Atlantic Forest and is considered a hotspot of anuran endemism (Silva et al 2018;Muscat et al 2020).…”

Using an integrative approach (morphology of the adult and larvae, bioacoustics, osteology, karyotype, and molecular data), we described a new tetraploid species of Odontophrynus to the Mantiqueira mountain range, in southeastern Brazil. The data suggest that Odontophrynus toledoi sp. nov., O. juquinha and Odontophrynus sp. (aff. juquinha) comprise a clade with specimens distributed along three distinct mountain ranges in Brazil: Mantiqueira (O. toledoi sp. nov.) and Espinhaço (O. juquinha) mountains, both in southeastern Brazil, and Diamantina Plateau (O. aff. juquinha), in northeastern Brazil. The new species is morphologically similar and closely related to O. juquinha, but is distinguished in morphology (both adult and larval), karyotype (O. toledoi sp. nov. is tetraploid and O. juquinha is diploid), and corroborated by phylogenetic inferences. We also show that these species do not exchange haplotypes in the 16s gene. Furthermore, although the raw acoustic parameters of Odontophrynus toledoi sp. nov. and O. juquinha overlap at the limits of their ranges, we found a clear difference in the acoustic space structure.

“…Observations along mountain ranges in south‐eastern Brazil have revealed that differences in climate, elevation and vegetational cover can impact habitat complexity and species composition (Cruz & Feio, 2007). The Serra do Mar mountain range is home to a greater number of species of plants (Marchiori et al, 2016; Pompeu et al, 2014), arthropods (Pinto‐da‐Rocha et al, 2005; Siegloch et al, 2012) and anurans (Malagoli et al, 2018; Silva et al, 2018) compared to the Serra da Mantiqueira mountain range. Anurans, known for their generalist and opportunistic feeding habits, prey on almost all kinds of invertebrates in their habitat (López et al, 2009; Rodrigues et al, 2004; Solé et al, 2009).…”

“…Despite the high degree of endemism observed among anurans in the Serra do Mar and Serra da Mantiqueira (Cruz & Feio, 2007), several species are found in both mountain ranges, including the rock river frog, Thoropa miliaris (Spix, 1824) (Cruz & Feio, 2007; Malagoli et al, 2018; Silva et al, 2018). From the larval stage to adult life, individuals of this species inhabit rocky habitats in the Atlantic Rainforest (Feio et al, 2006; Giaretta & Facure, 2004), from sea level to almost 1500 m a.s.l.…”

Trophic ecology of Thoropa miliaris (Anura: Cycloramphidae) in two mountain ranges of south‐eastern Brazil

Among populations of the same species, the diet composition varies depending on the environment, given the variation in diversity and abundance of available prey. Since Thoropa miliaris is a habitat specialist in reproduction, we tested the hypothesis that this specialization is also verified in its diet. We carried out the work in 10 localities in Serra do Mar and Serra da Mantiqueira, south‐eastern Brazil, where we collected frogs and evaluated prey availability. The environment did not provide significant variation in the diet of T. miliaris, and Formicidae was the prey category selectively consumed in greater volume, frequency and abundance in both mountain ranges. Therefore, we can state that T. miliaris has a selective diet on ants.

“…It is distributed for~900 km along the borders of São Paulo, Rio de Janeiro, Espírito Santo and Minas Gerais states, in southeastern Brazil. The Mantiqueira mountain range is one of the most diverse anuran areas in the Atlantic Forest domain and is considered a hotspot of anuran endemism [16]. The species richness and the high degree of endemism in Mantiqueira mountains are partly attributed to factors such as: altitudinal gradients, heterogeneity in phytophysiognomies and the presence of humid environments along the mountain chain [17][18][19].…”

Hidden by the name: A new fluorescent pumpkin toadlet from the Brachycephalus ephippium group (Anura: Brachycephalidae)

Species of Brachycephalus has been having taxonomical issues due its morphological similarity and genetic conservatism. Herein, we describe a new species of Brachycephalus from the south Mantiqueira mountain range and semidecidual forests in the municipalities of Mogi das Cruzes, Campinas and Jundiaí, state of São Paulo, Brazil, based on an integrative approach. It can be distinguished from all species of the B. ephippium species group based on morphological characters (especially osteology and head shape), advertisement call and divergence in partial mitochondrial DNA gene sequences (16S). The new species is genetically similar to B. margaritatus and morphologically similar to B. ephippium. It can be differentiated from B. ephippium by the presence of dark faded spots on skull and post-cranial plates, presence of black connective tissue connective tissue scattered over dorsal musculature, parotic plate morphology, smaller snout-vent length (adult SVL: males 13.46–15.92 mm; females 16.04–17.69 mm) and 3% genetic distance. We also present natural history data and discuss the robustness of the integrative approach, geographic distribution, genetic data, behaviour, fluorescence in ontogeny, and conservation status.
