We describe and name the second species of Phyzelaphryne (Brachycephaloidea, Eleutherodactylidae), from northwestern Brazilian Amazonia. Phyzelaphryne nimio sp. nov. is distinguished from its only congener, Phyzelaphryne miriamae, by its smaller body size and the anatomy of the carpal and metacarpal regions, with relatively larger (sometimes fused) supernumerary carpal and metacarpal tubercles. Molecular phylogenetic analyses based on fragments of the mitochondrial genes 16S rRNA and COI… Expand
A New Species of the Genus Adelophryne (Anura: Eleutherodactylidae: Phyzelaphryninae) from the Atlantic Forest of Northeastern Brazil
Abstract Species in the Adelophryne genus consist of diminutive, agile, and secretive frogs that inhabit forest leaf litter and have direct development. Species richness within Adelophryne wasExpand
A New Forest-Dwelling Frog Species of the Genus Adenomera (Leptodactylidae) from Northwestern Brazilian Amazonia
We describe a new species of the South American frog genus Adenomera, based on external morphology, color patterns, advertisement call, and mtDNA sequences. The new species was collected from theExpand
Five new country records of Amazonian anurans for Brazil, with notes on morphology, advertisement calls, and natural history
We report for the first time the occurrences in Brazil of Boana hobbsi, Osteocephalus deridens and Tepuihyla shushupe (Hylidae), and confirm the occurrences of Ranitomeya defleri and RanitomeyaExpand


A New Species of Clown Tree Frog, Dendropsophus leucophyllatus Species Group, from Amazonia (Anura, Hylidae)
A tree-alignment (direct optimization) parsimony analysis firmly support the new species of Dendropsophus from the Amazon river basin as the sister taxon of D. sarayacuensis. Expand
Systematics of spiny‐backed treefrogs (Hylidae: Osteocephalus): an Amazonian puzzle
A new taxonomy is proposed, securing the monophyly of Osteocephalus and Tepuihyla by rearranging and redefining the content of both genera and also erect a new genus for the sister group of O SteocephalUS. Expand
A taxonomic revision of the Neotropical poison frog genus Ranitomeya (Amphibia: Dendrobatidae)
The Neotropical poison frog genus Ranitomeya is revised, resulting in one new genus, one new species, five synonymies and one species classified as nomen dubium. We present an expanded molecularExpand
Molecular systematics of terraranas (Anura: Brachycephaloidea) with an assessment of the effects of alignment and optimality criteria.
The optimal tree-alignment indicates that insertions and deletions occurred in twice as many aligned positions as implied by the optimal similarity-Alignment, confirming previous findings that sequence turnover through insertion and deletion events plays a greater role in molecular evolution than indicated by similarity-alignments.

From Amazonia to the Atlantic forest: molecular phylogeny of Phyzelaphryninae frogs reveals unexpected diversity and a striking biogeographic pattern emphasizing conservation challenges.
The results suggest that the actual number of species in Phyzelaphryninae is, at least, twice the currently recognized species diversity, with almost every geographically isolated population representing an anciently divergent candidate species. Expand
A new genus and two new species of minute leptodactylid frogs from northern South America, with comments upon Phyzelaphryne (Amphibia: Anura: Leptodactylidae)
The synonymisation of Phyzelaphryne miriamae Heyer with Eleutherodactylus nigrovittatus Andersson is denied and it is shown that both species are quite distinct in numerous characters. A new genusExpand
A new diminutive frog species of Adelophryne (Amphibia: Anura: Eleutherodactylidae) from the Atlantic Forest, southeastern Brazil.
This species is sensitive to edge effect and conversion of native forest into coffee and Eucalyptus plantations and may be listed as Endangered (EN) under B1ab(iii) criteria of the IUCN Red List. Expand
New World direct-developing frogs (Anura: Terrarana): Molecular phylogeny, classification, biogeography, and conservation
New World frogs recently placed in a single, enormous family (Brachycephalidae) have direct development and reproduce on land, often far away from water and most of the 100 informal groups (species series, species groups, and species subgroups) are new or newly defined. Expand
A new species of Adelophryne (Anura: Eleutherodactylidae) from Guyana, with additional data on A. gutturosa
A new species of frog, Adelophryne patamona, from 678–1414 m elevation in the Pakaraima Mountains of Guyana, is described. The new species is distinguished by large size, second phalange of Finger IVExpand
Deciphering amphibian diversity through DNA barcoding: chances and challenges
It is suggested that a number of mitochondrial and nuclear genes may be used as DNA barcoding markers to complement cox1, and this taxon was able to correctly identify species including disparate geographic variants. Expand
