The Tadpole of Scinax cardosoi (Carvalho-e-Silva and Peixoto, 1991), with Description of Internal Oral Morphology and Taxonomic Considerations (Anura: Hylidae)

Treefrog Diversity in the Neotropics: Phylogenetic Relationships of Scinaxini (Anura: Hylidae: Hylinae)

“…Dias and Pie (2021) identified the occurrence of narial vacuities in the oral roof of larvae ( Ololygon belloni, O. littorea, O. perpusilla and O. v-signata ), the two cell types in the vacuities (known only in O. littorea ), and the presence of a single rounded, large postulation in the prenarial arena of the oral roof as putative synapomorphies of the O. perpusilla group or a potentially more inclusive clade, as these occur in some other species of Ololygon (Conte et al, 2007; Alcalde et al, 2011; Kirchmeyer et al, 2019). The taxonomic distribution of these character-states is still too poorly known in Scinaxini, and for this reason, we did not include them in our dataset, pending studies on larvae of more species.…”

“…Kirchmeyer et al (2019) described the external morphology and internal oral morphology of the tadpole of Scinax cardosoi and transferred this species to Ololygon (sensu Duellman et al, 2016 and the former Scinax catharinae clade sensu Faivovich et al, 2005) on the basis of adult and larval external morphology and call parameters similarities shared between O. cardosoi and other Ololygon species. Our observations on the type series of O. cardosoi corroborated that this species is part of Ololygon as redefined here mainly on the basis of the absence of pectoral folds, a characteristic shared by species of this genus.…”

The final molecular dataset includes 1,279 terminals of Scinax; among which 775 were sequenced for this project and 504 were obtained from GenBank.…”

Anuran species composition and density estimates from an Atlantic Forest area within the APA Serra da Mantiqueira, Rio de Janeiro state, Brazil

“…The treefrog Scinax cardosoi is another species that remains poorly known (Kirchmeyer et al 2019), being currently reported from a few isolated localities in the states of Espírito Santo, Minas Gerais, Rio de Janeiro and São Paulo, in southeastern Brazil (Frost 2021). Studies updating the geographic distribution of this species (Pinto et al 2009, Linares et al 2011, Moroti et al 2017) have omitted its presence in Visconde de Mauá, in the municipality of Resende, state of Rio de Janeiro, apparently overlooking the fact that one of its paratypes came from that locality (Carvalho-e-Silva & Peixoto 1991).…”

“…The village of Visconde de Mauá is about 6 km distant from our study site. More recently, Kirchmeyer et al (2019) reported five newly metamorphosed individuals from the Parque Nacional de Itatiaia. Those records, together with those of our study, confirm the presence of S. cardosoi in the region of Itatiaia and its occurrence in other areas within the state of Rio de Janeiro besides its type locality in Teresópolis municipality (Carvalho-e-Silva & Peixoto 1991).…”
