“…Of the 86 valid species of Rhinella, 25 have the tadpole known (Cei 1980;Heyer et al 1990;Caldwell 1991;Carvalho-e-Silva 1988;Eterovick & Sazima 1999;Carvalho-e-Silva et al 1994;Aguilar & Gamarra 2004;Borteiro et al 2006;Menin et al 2006;Lima et al 2007;Maciel et al 2007;Mercês et al 2009;Lourenço et al 2010;Tolledo & Toledo 2010;Fehlberg et al 2012;Ruas et al 2012) and only five have the internal oral morphology evidenced, as R. arenarum, R. icterica, R. ornata, R. quechua, R. schneideri and R. spinulosa (Fabrezi & Vera 1997;Prado 2006;Candioti 2007;Dias 2008;Aguayo et al 2009). Broad comparisons and generalizations about larval morphology exist for few taxa of anurans, which complicate the use of these characters in taxonomic and systematic studies.…”

From the 86 species allocated in the genus Rhinella, 25 have their tadpoles described and only R. arenarum, R. chrysophora, R. icterica, R. ornata, R. schneideri and R. spinulosa have aspects of the internal oral morphology evidenced. Herein, the internal oral morphology from 12 species of Rhinella distributed between the morphological groups of R. crucifer, R. granulosa, R. marina and R margaritifera is described and compared. The internal oral morphology of Rhinella is little variable in many aspects. Despite the many similarities found between the tadpoles of Rhinella, the study showed that there are characteristics that exhibit interspecific variation that can be used in the taxonomy of the genus. Important features to distinguish species were: number of infrarrostral projections; number and shape of the infralabial papillae; size, arrangement, shape and apex of the lingual papillae; shape of the buccal floor arena papillae; number of projections of the ventral velum; shape of the prenarial ridge; choanae arrangement; number and apex of the postnarial papillae; number and shape of the secondary branches on the lateral ridge papilla; buccal roof arena papillae arrangement.

The external morphology, internal oral morphology, the chondrocranium and the hyobranchial apparatus of Elachistocleis bumbameuboi, E. cf. piauiensis, E. cesarii and E. bicolor are described and compared with each other and with other species of microhylids using available descriptions from the literature. The general morphology of Elachistocleis species is conservative in many aspects. Differences between species are subtle and are found in the body shape, the edge of the snout, fin height, if the lateral line is evident, the presence of regular pustules in the buccal roof arena, the posterolateral edge of the cartilago suprarostralis, the shape of the fenestra in the occipital region, presence or absence of fenestra hypophysea, the margin of the processus antorbitalis, expansions in the ventrolateral process, the shape and inclination of the fenestra subocularis, whether the subotic process is single or slightly bifid, and the inclination of the processus anterolateralis hyalis.

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...
