The Eponym Dictionary of Amphibians

This book is a follow-up to the “Eponym Dictionary of Mammals” (2009) and “The Eponym Dictionary of Reptiles” (2011), both by the same authors. This series of books lists those species that were named for people, or in some cases for “a place that was itself named after a person”

Hylid frogs from Mount Ayanganna, Guyana: new species, redescriptions, and distributional records

A new species of Osteocephalus, one species of Hyla, three species of Hypsiboas and one of Myersiohyla were collected on Mount Ayanganna, a sandstone Guiana Shield tepui. Hyla warreni, Hypsiboas roraima, H. sibleszi, Myersiohyla kanaima and the new Osteocephalus were collected in high-tepui forest at 1500 m elevation, while Hypsiboas lemai, H. roraima and M. kanaima were also collected in lower montane forest at 870 m. Supplementary descriptions of adults of all species of Hyla, Hypsiboas and Myersiohyla based on the newly collected specimens are provided. Tadpoles of M. kanaima are described. The specimens from Ayanganna represent significant distributional records for several species. This is the first record of Osteocephalus as a member of the Guiana Shield high-tepui herpetofauna

Exceptional diversity of Stefania (Anura, Cryptobatrachidae) II: six species from Mount Wokomung, Guyana

Six species of Stefania were collected on Mount Wokomung, a tepui in the Pakaraima Mountains of Guyana. This unusually high diversity of Stefania is similar to that found on a neighbouring tepui, Mt. Ayanganna. The two tepuis support slightly different habitats. Conspecific Stefania from the two mountains differ somewhat in body size, toe disc size and colouration. Specimens from Mt. Wokomung are used to expand descriptions and distributions of some species

Morphological variation in Leptodactylus lutzi (Anura, Leptodactylidae) with description of its advertisement call and notes on its courtship behavior

Prior to this study, Leptodactylus lutzi was known only from three localities in west-central Guyana. We refer here to a series of 60 additional specimens of L. lutzi collected in Kaieteur National Park, Mount Ayanganna, Mount Wokomung and the Merume Mountains in the Pakaraima Mountains region, substantially extending the known distribution of the species. We provide a revised diagnosis and an expanded description of L. lutzi discussing the extent of color-pattern variation in the species. Additionally, we describe its advertisement call and provide data on its reproductive biology
