Book Description
Auyantepui is an immense sandstone table mountain in the Venezuelan Guayana. This mesa did not appear on aviation maps and was unknown to the literate world prior to the late 1930s. It was explored from the air by Jimmy Angel, a bush pilot and colorful soldier of fortune for whom the world's highest waterfall is named (Angel Falls at the northern end of Auyantepui). About the same time, in 1937, Captain Félix Cardona Puig and Gustavo Heny discovered an access crack in the sandstone, allowing ascent onto the southern end of the mesa. The first scientific exploration followed immediately--the 1937-1938 Phelps Venezuelan Expedition of the American Museum of Natural History made the first zoological and general botanical collections. Today, no tepui other than the "Lost World" of Cerro Roraima is better known to the general public. The summit of Auyantepui has a known fauna of 24 species of amphibians and reptiles, including species added by the Robert G. Goelet American Museum-TERRAMAR Expedition in 1994. This expedition collected 16 species during a month of fieldwork in the dry season (February), in five camps at elevations of 1700-2100 m above sea level. All species known from the summit of Auyantepui are treated in this bulletin; illustrations where possible include tadpoles, bioacoustic spectrograms, and hemipenes. Four new species are described--two frogs (Hypsiboas angelicus, n. sp., Eleutherodactylus auricarens, n. sp.), a lizard (Arthrosaura montigena, n. sp.), and a snake (Atractus guerreroi, n. sp.). Arthrosaura montigena possesses a hemipenial character not previously described--an orifice (orificium) of unknown function, situated in the lobular crotch between the two lobes. Attention is called to a probably undescribed snake (Liophis "miliaris" sensu lato) from the nearby Gran Sabana. The herpetofauna of the Auyán summit comprises 12 families, 20 genera, and 24 species. This is compared with the known herpetofauna of the Chimantá massif, lying less than 50 km south-southeast of Auyantepui. Despite the proximity and similar dimensions, the summits of Auyantepui and Chimantá have in common only 11% of the combined number of species (4 of 36), 44% of the genera (11 of 25), and 62% of the families represented (8 of 13), showing that neighboring tepuis may have herpetofaunas very different from one another. Nonetheless, the adjacent mountains that constitute the more fragmented Chimantá massif are relatively close to one another and seem to have a unified herpetofauna.

Book Description
Biodiversity of Pantepui: The Pristine "Lost World" of the Neotropical Guiana Highlands provides the most updated and comprehensive knowledge on the biota, origin, and evolution of the Pantepui biogeographical province. It synthesizes historical information and recent discoveries, covering the main biogeographic patterns, evolutionary trends, and conservational efforts. Written by international experts on the biodiversity of this pristine land, this book explores what makes Pantepui a unique natural laboratory to study the origin and evolution of Neotropical biodiversity under the influence of only natural drivers. It discusses the organisms living in Pentepui, including algae, plants, several groups of invertebrates, birds, amphibians, reptiles, and mammals. The latter portion of the book delves into the effects of human activity and global warming on Pantepui, and current conservational efforts to combat these threats. Biodiversity of Pantepui is an important resource for researchers in ecology, biogeography, evolution, and conservation, who want to understand the biodiversity and natural history of this region, and how to help conserve and protect the Guiana Highlands from environmental and human damages.
