The Atlantic Rain forest, which is considered the second largest pluvial forest in the American continent, has had an estimated 93% of its original area destroyed. Although studies concerning the herpetofaunal diversity in this biome have been intensified in the past years, its diversity is still underestimated. The Nucleo Experimental de Iguaba Grande (NEIG) is included in an Environmental Protection Area (APA de Sapeatiba) in the Iguaba Grande municipality, Rio de Janeiro state, Brazil (22º 51' S and 42º 10' W). The goal of this study was to conduct an inventory of the reptile and amphibian species that occur in this area between July 2008 and December 2009. We recorded 19 species of amphibians (18 anurans and one caecilian) and 15 species of reptiles (three lizards, 11 snakes and one amphisbaenian). Leptodactylus latrans and L. mystacinus had the highest capture rates among amphibians captured, and among reptiles, Ameiva ameiva, Hemidactylus mabouia and Mabuya agilis had the highest capture rates. Rarefaction curves for both amphibians and reptiles did not reach the asymptote, indicating that the species richness in the NEIG is still underestimated.
大西洋雨林被认为是美洲大陆第二大降雨森林，其原始面积估计已被破坏了93%。尽管在过去几年中，关于这个生物群落中两栖爬行动物多样性的研究有所加强，但其多样性仍然被低估。伊瓜格兰德实验中心（NEIG）位于巴西里约热内卢州伊瓜格兰德市的一个环境保护区（萨佩蒂巴环境保护区）内（南纬22°51′，西经42°10′）。本研究的目的是对2008年7月至2009年12月期间该地区出现的爬行动物和两栖动物物种进行清查。我们记录了19种两栖动物（18种无尾目动物和1种蚓螈）和15种爬行动物（3种蜥蜴、11种蛇和1种蚓蜥）。在捕获的两栖动物中，拉氏细趾蟾和神秘细趾蟾的捕获率最高，在爬行动物中，亚马逊鞭尾蜥、马布亚睑虎和敏捷马布亚的捕获率最高。两栖动物和爬行动物的稀疏曲线均未达到渐近线，这表明伊瓜格兰德实验中心的物种丰富度仍然被低估。
