“…Here, we found evidence of Pebas system promoting the diversi cation of arboreal anurans, given that the three most speciose genus in Phyllomedusidae had origin and diversi cation in this area. This is an important nding, since other studies regarding arboreal frog groups have shown diversi cation after the regression of the Pebas system (Boana albopunctata species group; Fouquet et al, 2021b). As far as we know, our present study is the most comprehensive framework about this issue.…”

The species richness in Neotropics has been linked to environmental heterogeneity and a complex geological history. We evaluated which biogeographical processes were associated to the diversification of Monkey tree frogs, an endemic group from Neotropics which was hypothesised to have a south-north pattern of diversification. We used 14 molecular markers on a bayesian analysis to infer phylogenetic relationships among 53 species of Phyllomedusidae and to estimate their divergence times. We defined 17 biogeographical units based on the distribution of the species utilised in our study. Ancestral range estimations were made using models implemented in BioGeoBEARS.We found that genera-level resolution was well-supported as older divergences. Phyllomedusidae ancestor range was uncertain, showing a most probable range in Western Amazonia. Phyllomedusids diverged mostly through jump-dispersal events, with anagenetic dispersals occurring mostly in the last 10 million years. The biogeographical history of monkey tree frogs is rather complex, being influenced by the Neotropical landscape evolution. Diversification was shown to have a north-south pattern within the family, through predominantly jump-dispersal and sympatry processes. Future studies could elaborate further the early history of the group.

These candidate species, together with other recently described species ( Ferrão et al, 2017 ; Ferrão et al, 2020a ; Ferrão et al, 2020b ; Fouquet et al, 2021a ; Fouquet et al, 2021b ; Melo-Sampaio, Ferrão & Moraes, 2021 ; Ferrão et al, 2022 ), highlight both the importance of the upper Madeira Basin as a center of regional biodiversity and the need for additional taxonomic studies in this threatened part of Amazonia.…”

“…Many species of Amazonian frogs once thought to be geographically widespread are now known to contain numerous additional species, each with a narrow distribution ( Lima, Ferrão & Silva, 2020 ; Vacher et al, 2020 ; Fouquet et al, 2021a ; Fouquet et al, 2021b ). This phenomenon is especially evident in nurse frogs of the genus Allobates ( Zimmermann & Zimmermann, 1988 ).…”

Cryptic diversity is extremely common in widespread Amazonian anurans, but especially in nurse frogs of the genus Allobates. There is an urgent need to formally describe the many distinct but unnamed species, both to enable studies of their basic biology but especially to facilitate conservation of threatened environments in which many are found. Here, we describe through integrative taxonomy a new species of the Allobates tapajos species complex from the upper Madeira River, southwestern Amazonia. Species delimitation analyses based on molecular data are congruent and delimit five candidate species in addition to A. tapajos sensu stricto. The new species is recovered as sister to A. tapajos clade F, a candidate species from Teles-Pires River, southeastern Amazonia. The new species differs from nominal congeners in adult and larval morphology and in male advertisement call. Egg deposition sites differ between east and west banks of the upper Madeira River, but there is no evidence of corresponding morphologic or bioacoustic differentiation. The new species appears to be restricted to riparian forests; its known geographic range falls entirely within the influence zone of reservoirs of two large dams, which underscores the urgent need of a conservation assessment through long-term monitoring. This region harbors the richest assemblage of Allobates reported for Brazilian Amazonia, with six nominal species and four additional candidate species awaiting formal description.

“…The population previously identified as Boana multifasciata (Günther, 1859) from the Guiana Shield is currently known to be an unnamed candidate species, inhabiting the Guianas and the Brazilian states of Roraima, Pará and Amapá (Fouquet et al 2021c) based only on molecular data. We added the molecularbased records from Vacher et al (2020) and Fouquet et al (2021c) corresponding to this taxon, as well as the literature records with overall morphology more similar to B. multifasciata. We decided to keep using this name for Amapá populations until more studies clarify their taxonomic status.…”

We herein present the first annotated anuran checklist for the Brazilian state of Amapá, eastern Amazonia, based on a thorough literature review. We recorded the occurrence of 111 species belonging to 13 anuran families distributed across 48 localities throughout Amapá, within two biomes. Among these species, 62.5% occur exclusively in the Tropical Moist Broadleaf Forest biome, ~8% occur exclusively in the Tropical Savanna biome, and ~29% occur in both. Two species were considered endemic to Amapá and were registered only in the central portion of the state. Regarding the conservation status, only one species (Dendropsophus amicorum) is classified as threatened, assigned to the “critically endangered” category. The other species are categorized as either “least concern” or “data deficient” (85 and 8, respectively), whereas 21 are not evaluated. The current annotated list contributes to the incipient knowledge on anuran species richness in Amapá and, despite the research regarding anuran taxonomy has considerably progressed over the past 20 years, there is still much to do. Our data highlight the need for trained taxonomists to develop research in the state.
