We recorded 15 species of lizards, 4 amphisbaenas, 23 snakes, 2 chelonians and 31 frogs. Out of 21 amphibian species, we collected only five of them with pitfall traps as well as through active search Table 1. Results and Discussion We recorded 1, individuals pertaining to 37 species of reptiles 25 lizards, three amphisbaenians, 11 snakes, and one chelonian and 21 species of amphibians Caaginga 1Dx 3 – 8.
Nevertheless, more species are likely to be incorporated to the local lizard richness.
However, snake richness will increase considerably with more sampling effort and consequently the number of reptiles will rise. Despite this caattinga in herpetofaunal inventories, information for many areas of the biome is still lacking and new surveys are required. It is more likely to find snakes and turtles during active searches or sporadically.
Herpetofauna of protected areas in the Caatinga III: The Catimbau National Park, Pernambuco, Brazil
The lizard richness is higher than other Caatinga areas, which typically range from 14 to 21 species VittCavalcanti et al. We attempted to show the great potential of Catimbau National Park, characterized by the richest herpetofauna surveyed in a core region of the biome, along with the presence of endemic species such as the worm snake Amphisbaena supranumeraria and the limbless lizard Scriptosaura catimbauunderscoring the importance of the area for the conservation and maintenance of the Caatinga herpetofauna biodiversity.
Despite the increase in herpetofaunal inventories in caztinga Caatinga biome, information for many areas is still lacking and new surveys are required. Thirty-five pitfall trap arrays composed of 4 buckets each, coupled with glue traps, and haphazard searches were used to sample the herpetofaunal diversity. Abstract We provide a list of amphibians, lizards, chelonians, and snakes collected during a day expedition to the northern portion of Chapada Diamantina National Park, Palmeiras municipality, Bahia State, Brazil.
We recorded 1, individuals pertaining to 37 species of reptiles 25 lizards, three amphisbaenians, 11 snakes, and one chelonian and 21 species of amphibians Table 1Figures 3 – 8.
The authors are grateful to all researchers that helped sometime during the fieldwork. Finally, the number of endemic and undescribed species recorded in this study provides additional evidence of the importance of Chapada Diamantina for the maintenance and conservation of the herpetofauna within the Caatinga domain. We also carried random active searches for specimens, which were conducted in the morning, in the afternoon, and at night, in the following locations and trails, locally knows as: Also, the region is considered to be of extreme biological importance due its richness and endemism MMA This is supported by our results, which show species accumulation curves quite asymptotic for amphibians and lizards but not for reptiles and snakes, and that species richness estimates were higher than the observed number of species, specially for reptiles and snakes.
The Park has an area of approximately 62, ha, and ranges from m to 1, m of altitude. Rarefaction curves and richness estimators suggest that local biodiversity is still underestimated. We also found a high diversity of lizards in Catimbau National Park. The inventory was conducted from March 13th to April 14th, Leiuperinae from Northeastern Brazil. All traps were checked daily. The glue traps were efficient for lizard survey, capturing 64 individuals from 13 species.

Interpolating, extrapolating and comparing incidence-based species accumulation curves. All amphibians found in Catimbau National Park were anuran species distributed in seven families.
In this study, our principal goal, using the same methodology to describe and compare the herpetofauna of the protected areas in Caatinga biome has been reached see Garda et al. Herpefofauna 17, ; Accepted: Despite these findings, our rarefaction curves suggest that local biodiversity is still underestimated, which reinforces the need for future inventories in this and in less studied sites along this region.

Herpetofauna of herpetofanua areas in the Caatinga IV: Acknowledgements The authors are grateful to all researchers that helped sometime during the fieldwork. In order TO cover the widest range of microhabitat and activity periods possible, we further searched sites with different phytophysiognomies, like dense vegetation areas, open vegetation areas with sandy soils, rock crops, and areas with water bodies.
