“…É encontrada freqüentemente em áreas abertas, associada aos riachos permanentes de fundo pedregoso e poças, onde machos vocalizam nas margens durante a noite na estação seca (de abril a setembro) e, em geral, com a parte posterior do corpo submersa (Eterovick & Sazima 2004). Diferencia-se da outra espécie do mesmo gênero que ocorre na área por apresentar um tamanho relativamente menor, coloração do ventre e membros avermelhada e não possuir a glândula paracnêmica na tíbia, característica de Rhinella schneideri (Lutz 1934). Indivíduos foram avistados de agosto a outubro no PEFBJ, porém somente em agosto (fim da estação seca) machos foram avistados vocalizando em brejos, córregos e lagoas permanentes.…”

amphibians of Parque Estadual das Furnas do Bom Jesus, Southeastern Brazil, and its relationships with other assemblages in Brazil. Biota Neotrop., 9(2): http://www.biotaneotropica.org.br/v9n2/en/abstract?article+bn01309022009. Abstract:We present the 24 anuran species occuring in Parque Estadual das Furnas do Bom Jesus (PEFBJ), municipality of Pedregulho, São Paulo state, southeastern Brazil. Barycholos ternetzi, Rhinella rubescens, Scinax canastrensis, and Phyllomedusa ayeaye correspond to new records to the São Paulo state species list, the latter species considered as threatened in IBAMA and IUCN lists. In order to characterize the PEFBJ anuran assemblage we compare its species composition with 66 localities from different biomes in Brazil. The 67 assemblages were ordinated and grouped by Principal Coordinates Analysis (ACOP) and Cluster Analysis. The multivariate analysis allowed the identification of four groups: one from Amazonian forest assemblages; two from Atlantic forest assemblages, being one consisting of dense Atlantic rain forest of Bahia, Espírito Santo states and its transitions with seasonal semideciduous forests (Minas Gerais state), and the other one consisting of localities of dense Atlantic rain forest of Rio de Janeiro, São Paulo, Paraná states and its transitions with araucaria rain forest (Atlantic rain forest with Araucaria angustifolia), seasonal semideciduous forests, and Pampas Biome assemblages; assemblages from more open physiognomies, as Caatinga (semiarid steppe of Northeast Brazil), Cerrado (Brazilian savanna), Pantanal (Brazilian wetlands), and the Atlantic forest (seasonal semideciduous forests) were included in the fourth group. The faunistic groups obtained indicate that species composition of the 67 localities are strongly related to the vegetation types where they occur. The great diversity observed among the physiognomic vegetation types could be related to the topographic and climatic variations found in the different biomes considered in our analysis (Amazon, Caatinga, Cerrado, Atlantic forest, Pampas and Pantanal). The anuran assemblage of PEFBJ was grouped among the biomes with open phytophysiognomies (fourth group), showing great similarity to the faunas of Cerrado and semideciduous forests in the Atlantic forest Biome of São Paulo state. do Parque Estadual das Furnas do Bom Jesus, sudeste do Brasil, e suas relações com outras taxocenoses no Brasil.

“…By its build and general appearance, this toad is more similar to B. arenarum Hensel, a southern species with a wide distribution and many regional morphs (Cei, 1972), than to any other toad occurring in southeastern South America. Bufo paracnemis A. Lutz, a large species with tibial glands (Lutz, 1934;Cochran, 1955), also belongs to the B. marinus group (sensu Cei, 1972) and occurs in sympatry with B. rufus in the Serra do Espinhaco range, Minas Gerais, southeastern Brazil (Feio et al, in press). Of the three species of the B. marinus group (sensu Cei, 1972) occurring in southeastern Brazil, Gosner, 1960), were found in May.…”

“…This species group was recognized as distinct from the Rhinella marina Group by R.F. Martin (1972b) and Duellman and Schulte (1992) and all its forms were considered as a single species (Bufo crucifer) for a long time (see Lutz, 1934;Cochran, 1955;Cei, 1980;Duellman and Schulte, 1992). Baldissera et al (2004) revised the taxonomy of this species group and recognized five species based on morphology and morphometrics: Rhinella abei (Baldissera et al, 2004), R .…”

True toads of the genus Rhinella are among the most common and diverse group of Neotropical anurans. These toads are widely distributed throughout South America, inhabiting a great diversity of environments and ecoregions. Currently, however, the genus is defined solely on the basis of molecular characters, and it lacks a proper diagnosis. Although some phenetic species groups have traditionally been recognized within Rhinella, the monophyly of some of them have been rejected in previous phylogenetic analyses, and many species remain unassigned to these poorly defined groups. Additionally, the identity and taxonomy of several species are problematic and hinder the specific recognition and description of undescribed taxa. In this work, we first perform phylogenetic analyses of separate mitochondrial and nuclear datasets to test the possible occurrence of hybridization and/or genetic introgression in the genus. The comparative analysis of both datasets revealed unidirectional mitochondrial introgressions of an unknown parental species into R . horribilis ("ghost introgression") and of R . dorbignyi into R . bernardoi; therefore, the mitochondrial and nuclear datasets of these species were considered separately in subsequent analyses. We performed total-evidence phylogenetic analyses that included revised molecular (four mitochondrial and five nuclear genes) and phenotypic (90 characters) datasets for 83 nominal species of Rhinella, plus several undescribed and problematic species and multiple outgroups. Results demonstrate that Rhinella was nonmonophyletic due to the position of R . ceratophrys, which was recovered as the sister taxon of Rhaebo nasicus with strong support. Among our outgroups, the strongly supported Anaxyrus + Incilius is the sister clade of all other species of Rhinella. Once R . ceratophrys is excluded, the genus Rhinella is monophyletic, well supported, and composed of two major clades. One of these is moderately supported and includes species of the former R . spinulosa Group (including R . gallardoi); the monophyletic R . granulosa, R . crucifer, and R . marina Groups; and a clade composed of the mitochondrial sequences of R . horribilis. The other major clade is strongly supported and composed of all the species from the non-monophyletic R . veraguensis and R . margaritifera Groups, the former R . acrolopha Group, and R . sternosignata. Consistent with these results, we define eight species groups of Rhinella that are mostly diagnosed by phenotypic synapomorphies in addition to a combination of morphological character states. Rhinella sternosignata is the only species that remains unassigned to any group. We also synonymize nine species, treat three former subspecies as full species, and suggest that 15 lineages represent putative undescribed species. Lastly, we discuss the apparently frequent occurrence of hybridization, deep mitochondrial divergence, and "ghost introgression"; the incomplete phenotypic evidence (including putative character systems that could be used for future phylogenetic...
