Summary: Scinax is a genus of Neotropical treefrogs with the most species diversity. It consists of 129 recognized species divided into two major clades, the S. catharinae and S. ruber clades. The relationships within and among these clades and their species groups are poorly understood. A phylogenetic analysis was conducted using genetic and phenotypic data, resulting in the partitioning of Scinax into three genera and the recognition of 13 species groups in the S. ruber clade and seven species groups in the S. catharinae clade. The study also identified 57 candidate species, highlighting the incomplete understanding of the diversity of this treefrog clade.

Summary: We have discovered a new and spectacular frog species in the Hyloscirtus genus, belonging to the H. larinopygion species group. The species is characterized by black body color with red spots, and the juveniles have a yellow body with black markings. The new species is closely related to other species in the H. larinopygion group in terms of phylogeny.

Summary: A new species of Hyloscirtus has been discovered in recent surveys in the Rio Negro-Sopladora National Park. This species is distinct from others due to its large body size, broad dermal fringes, and unique coloration patterns. It is currently only found in the high montane forest in southeastern Ecuador.

Summary: Arboreal embryos of red-eyed treefrogs hatch prematurely in response to hypoxia and mechanosensory cues in snake attacks. However, hatching later improves tadpole survival. Risk assessment decreases as hatchling survival improves, and hatching performance increases as embryos develop. Snakes eat faster than embryos asphyxiate, leading to embryos deciding to hatch sooner and hatch faster in response to mechanosensory cues.

Summary: Although amphibian consumption by humans has been reported globally, this practice is not well studied despite its direct implications to the decline of amphibian populations. The consumption of Duellmanohyla ignicolor tadpoles by the Chinantec people in Mexico is documented and analyzed in this study, highlighting the vulnerability of the species due to their behavior and habitat preferences.

Summary: A new species of hylid frog has been discovered in Tapir Valley Nature Reserve in Costa Rica. The frog, classified as Tlalocohyla, is distinct from other species in the genus and is closely related to two other species. It can be identified by its green coloration and distinct markings on the back. The new species is currently only found in one specific location.

Summary: This study found spatial and temporal structuring of Scinax curicica populations in the campo rupestre of the Espinhaco Mountain Range in Brazil. Three lineages were identified, with stable population sizes over time, possibly due to the climatic stability in mountaintop areas.

Summary: This study reevaluates the taxonomic status of Eleutherodactylus bilineatus and its related genera through phylogenetic analyses and morphological traits, proposing the establishment of a new genus. The non-monophyly of Noblella was also discovered, with species from central Andes and northern Andes belonging to different clades. Additionally, distribution patterns suggest connections among distant biogeographical areas of South America.

Summary: This study conducted morphometric and genetic analyses of populations of Dendropsophus molitor and Dendropsophus luddeckei to test the validity of the recent taxonomic split. The results suggest that D. luddeckei is not a valid species and D. molitor should be considered a single species. This study highlights the danger of taxonomic inflation in the face of limited geographic sampling and a lack of clear diagnostic characters.
