A new species of the Scinax cruentomma group (Anura: Hylidae) from the Ucayali River basin of Loreto, Peru.

We describe a new species of the Scinax cruentomma species group, with a red streak in the iris and a weakly bilobate vocal sac. It is known from oligotrophic soils in the sedimentary basin of the Ucayali River near Jenaro Herrera (province of Requena, Peru) and Ro Blanco (buffer zone of the Matses Indigenous territory and reserve). The new species can be distinguished from the other species of the S.

A new species of Chiasmocleis Méhely, 1904 (Anura: Microhylidae) from the Peruvian Amazonia.

We describe a new species of Chiasmocleis from the Amazonian forest of Peru. The new species is characterized by its medium size (snout-to-vent length = 18.2-20.

A new species of nurse-frog (Aromobatidae, Allobates) from the Amazonian forest of Loreto, Peru.

We describe a new species of nurse-frog (Aromobatidae, Allobates) from the Amazonian forest of Loreto, Peru using morphological, acoustic and genetic data. Our phylogenetic analysis placed Allobates sieggreenae sp. nov.

The phylogeny of the Casque-headed Treefrogs (Hylidae: Hylinae: Lophyohylini).

The South American and West Indian Casque-headed Treefrogs (Hylidae: Hylinae: Lophyohylini) include 85 species. These are notably diverse in morphology (e.g.

Applied science facilitates the large-scale expansion of protected areas in an Amazonian hot spot.

Meeting international commitments to protect 17% of terrestrial ecosystems worldwide will require >3 million square kilometers of new protected areas and strategies to create those areas in a way that respects local communities and land use. In 2000-2016, biological and social scientists worked to increase the protected proportion of Peru's largest department via 14 interdisciplinary inventories covering >9 million hectares of this megadiverse corner of the Amazon basin. In each landscape, the strategy was the same: convene diverse partners, identify biological and sociocultural assets, document residents' use of natural resources, and tailor the findings to the needs of decision-makers.

Redescription and phylogenetics of emAllobates/em emtrilineatus/em (Boulenger 1884 "1883") (Anura: Aromobatidae) based on topotypic specimens.

Allobates trilineatus is the second most geographically widespread species in the genus Allobates, its range extending from northern Ecuador to southern Peru along the Andean foothills of Amazonia and to the east, into Acre, Brazil. However, detailed phenotypic and genetic variation from topotypic specimens is lacking, raising doubts about the identification of specimens in the literature. To solve this problem, we collected 16 topotypic specimens-including male and female adults and juveniles-and associated data such as advertisement calls and tissue samples.

The advertisement call of Chiasmocleis (Syncope) carvalhoi (Nelson, 1975) (Anura: Microhylidae), with taxonomic remarks based on new morphological observations of specimens from Peruvian Amazonia.

We quantitatively describe for the first time the advertisement call of Chiasmocleis (Syncope) carvalhoi using recordings  of five specimens from northern Peruvian Amazonia. The advertisement call is characterized by a single, short, tonal, and high-pitched note. Call duration ranges between 0.

Taxonomic status of the Neotropical salamanders Bolitoglossa altamazonica and Bolitoglossa peruviana (Amphibia: Caudata: Plethodontidae), with the description of a new species from Northern Peru.

We examine the phylogenetic relationships among salamanders of the genus Bolitoglossa (Eladinea) distributed in the Amazonian basin of northern Peru and southern Ecuador and assess species diversity based on morphological and phylogenetic analyses. We infer a molecular phylogeny using sequences from two mitochondrial (Cytb, 16S) and two nuclear genes (RAG-1, POMC). We find two well-supported subclades, one including [B.

Vastly underestimated species richness of Amazonian salamanders (Plethodontidae: Bolitoglossa) and implications about plethodontid diversification.

We present data showing that the number of salamander species in Amazonia is vastly underestimated. We used DNA sequences of up to five genes (3 mitochondrial and 2 nuclear) of 366 specimens, 189 corresponding to 89 non-Amazonian nominal species and 177 Amazonian specimens, including types or topotypes, of eight of the nine recognized species in the region. By including representatives of all known species of Amazonian Bolitoglossa, except for one, and 73% of the currently 132 recognized species of the genus, our dataset represents the broadest sample of Bolitoglossa species, specimens, and geographic localities studied to date.

A new species of Phyzelaphryne Heyer, 1977 (Anura: Eleutherodactylidae) from the Japurá River basin, with a discussion of the diversity and distribution of the genus.

We describe and name the second species of Phyzelaphryne (Brachycephaloidea, Eleutherodactylidae), from northwestern Brazilian Amazonia. Phyzelaphryne nimio sp. nov.

A new species of nurse-frog (Aromobatidae, Allobates) from the Juami River basin, northwestern Brazilian Amazonia.

We describe a new species of nurse-frog (Aromobatidae, Allobates) from northwestern Brazilian Amazon. Allobates juami sp. nov.

Systematics of with the description of a new species and comments on the taxonomy of (Anura, Hylidae).

is an Amazonian hylid of uncertain phylogenetic position. Herein DNA sequences of mitochondrial and nuclear genes are used to determine its phylogenetic relationships. New sequences and external morphology of are also analyzed to assess the status of Ecuadorian and Peruvian populations.
