Abstract The leaf or monkey frogs of the hylid subfamily Phyllomedusinae are a unique group charismatic anurans. We present molecular phylogenetic analysis that includes 45 60 species phyllomedusines using up to 12 genes and intervening tRNAs. aims were gain better understanding position Phrynomedusa , test monophyly explore relationships among several putative lineages ( Hylomantis H. buckleyi Group, Phasmahyla four groups Phyllomedusa remain unassigned any group), examine implications our...
Abstract Declines and extinctions are increasing globally challenge conservationists to keep pace with biodiversity monitoring. Organisms leave DNA traces in the environment, e.g., soil, water, air. These referred as environmental (eDNA). The analysis of eDNA is a highly sensitive method potential rapidly assess local diversity status threatened species. We searched for 30 target amphibian species conservation concern, at different levels threat, using an metabarcoding approach, together...
Scinax is the most species-rich genus of Neotropical treefrogs, with 129 currently recognized species divided between two major clades, S. catharinae and ruber clades. The clade includes 52 placed in perpusillus groups, whereas composed 77 species, 13 which are included groups: rostratus uruguayus all 64 remaining being unassigned to any group. Although some studies have addressed phylogenetic relationships genus, its remain poorly understood. To test monophyly within among them, we...
We present a molecular phylogenetic analysis of the hylid tribe Hylini, with goals testing monophyly genera Duellmanohyla, Isthmohyla, and Ptychohyla providing discussion on Bromeliohyla, Charadrahyla, Ecnomiohyla, Exerodonta, Megastomatohyla, Sarcohyla. Our results indicate paraphyly Ptychohyla, Bromeliohyla Duellmanohyla nested within it, and, as in previous analyses, (due to legleri P. salvadorensis being it). To resolve this situation, we restrict contents redelimit those erect two new...
Abstract The two species of the Bokermannohyla claresignata group (Anura: Hylidae) have not been collected for last four decades. It is only hyline tribe Cophomantini that has yet analysed genetically. Its phylogenetic position thus uncertain, and it a combination adult larval character states make this crucial missing piece hinders our understanding phylogenetics evolution. We obtained DNA sequences from museum specimen Bok. claresignata, using specialized extraction methods high-throughput...
Thoropa comprises seven recognized species, including T. bryomantis, lutzi, megatympanum, miliaris, petropolitana, saxatilis, and taophora. It was believed that the syntypes of petropolitana were destroyed during Dresden bombings in World War II; however, there are two extant amphibian collection American Museum Natural History where they transferred from Staatlichen für Tierkunde 1923. Herein we designate a lectotype for provide taxonomic history synonymy, redescription, summary its...
We describe a new species of tree frog the Scinax ruber clade from rocky field mountains in states Goiás and Minas Gerais central southeastern Brazil. rogerioi sp. nov. is characterized by medium size (SVL males 25.0–35.6 mm; females 28.0–34.5 mm); snout protruding lateral view almost subovoid dorsal view; loreal region concave; adhesive discs on fingers medium-sized, wider than long; interrupted, irregular dark brown blotches dorsum behind eyes to inguinal head region; inverted triangular...
Abstract We studied the morphological variation of nuptial pads using light microscopy and scanning electron (SEM) in 26 species phyllomedusines (Anura: Hylidae), representing five currently recognized genera. All have single with dark colored epidermal projections (EPs). Spine‐shaped EPs occur Cruziohyla calcarifer , Phrynomedusa appendiculata one Phasmahyla . The other roundish EPs. density on pad is variable. Species Phyllomedusa hypochondrialis Group a that varies between 764 ± 58/mm 2...
Even though Brazil is the world leader in amphibian diversity, a significant part of its richness remains unknown or hidden under cryptic taxa. Here, we used model-based species delimitation an integrative taxonomic approach, by gathering molecular and morphometric data to assess taxa within monkey frogs Pithecopus rohdei, from Atlantic Forest, P. megacephalus, campos rupestres ecosystem. We sampled one mitochondrial, five nuclear loci, 18 variables. Using species-delimitation methods with...
The taxonomy of many species is still based solely on phenotypic traits, which often a pitfall for the understanding evolutionary processes and historical biogeographic patterns, especially between closely related due to either conservatism or plasticity. Two widely distributed Neotropical leaf frogs from Phyllomedusa burmeisteri group ( P. bahiana ) constitute paramount example with relatively unstable taxonomic history large variation. Herein, we analysed ~260 individuals 57 localities...
We describe Scinax pombali sp. n. a new species of treefrog the catharinae group from Serra da Canastra, mu-nicipality Capitólio (20o36’03’’S, 46o17’34.9’’W, 987 m a.s.l.), located in Cerrado domains State Minas Gerais, Southeastern Brazil. The is characterized by its small size, blotches and color pattern on dorsal surface hidden regions flanks thighs, canthus rostralis lightly concave well marked, absent nuptial pad, lack externally differentiated inguinal gland. Additionally, we tadpole...
Based on the analysis of type specimens and recently collected specimens, taxonomic status Phyllomedusa ayeaye (B. Lutz, 1966) itacolomi Caramaschi, Cruz & Feio, 2006 is reevaluated. We concluded that both species are morphologically indistinguishable therefore name designated as a junior synonym ayeaye. Additionally, we suggest removal P. from Red Lists threatened species.
We present the first taxonomic review of genus Phrynomedusa since its description with diagnoses and species. a broad literature provide updates remarks about type series, tadpoles, calls, geographic distribution, natural history species Phrynomedusa. Additionally we describe new from município de São Luiz do Paraitinga, state Paulo, Brazil. dryade was initially identified as marginata; however, an integrated analysis morphological molecular characters enabled recognition separate For time,...
We describe a new species of treefrog from the ruber clade genus Scinax, Serra do Cabral, State Minas Gerais, Brazil. Scinax cabralensis is characterized by small size, slightly arched and faintly distinct canthus rostralis, spotted pattern coloration on dorsum, thighs with transversal bars, granular skin dorsum venter, rounded snout in dorsal view, advertisement call. Additionally, data territorial calls notes natural history habitat are provided.
Amphibian parasites of the Order Dermocystida (Ichthyosporea) are widespread pathogens known mainly from Europe and North America, which cause primarily a disease skin subcutaneous tissue in their hosts. The taxonomy these organisms has been problematic given conserved morphology, similar clinical pathology. Currently recognized taxa belong to three closely related genera, Amphibiocystidium, Amphibiothecum, Rhinosporidium, whereas species Dermocystidium Sphaerothecum destruens include fish...
We describe the buccal cavity and chondrocranial morphology of Phasmahyla cruzi tadpoles in comparison to P. guttata. also provide a review some characters for larval phyllomedusids discuss evolutionary aspects related funnel-mouthed configuration. Our discussion highlights that several evolved independently taxa with umbelliform oral discs. Nevertheless, we suggest dorsal orientation suprarostral cartilage presence prenarial ridge on roof may represent synapomorphic character states genus...
