We present an inventory of the amphibians and reptiles of the San Vito de Coto Brus region, including the Las Cruces Biological Station, in southern Costa Rica, which is the result of a survey of the herpetofauna occurring in mountain forest fragments, pastures, coffee plantations, and other disturbed areas. We found 67 species, included 26 species of amphibians and of 41 of reptiles. We describe the distribution patterns of the community on the basis of the life zones, elevation, fragmentation, and degree of anthropogenic impact. We also provide some nouvelle data on the systematics of some select taxa, their geographical ranges, microhabitats, activity, and other relevant ecological and natural history features. Finally, we comment on the present conservation status of the herpetofauna in the region. Previous literature and collection records indicate a higher number of species occurring in this area, which suggests that some declines have occurred, especially of amphibians, in last decades.
我们展示了哥斯达黎加南部科托布鲁斯省圣维托地区（包括拉斯克鲁塞斯生物站）的两栖动物和爬行动物名录，这是对山地森林碎片、牧场、咖啡种植园及其他受干扰地区出现的爬虫类动物进行调查的结果。我们发现了67个物种，其中包括26种两栖动物和41种爬行动物。我们根据生物带、海拔、碎片化程度和人为影响程度描述了群落的分布模式。我们还提供了一些关于某些选定分类群的系统学、它们的地理范围、微生境、活动以及其他相关生态和自然历史特征的新数据。最后，我们评论了该地区爬虫类动物目前的保护状况。先前的文献和收集记录表明该地区出现的物种数量更多，这表明在过去几十年里某些物种数量有所下降，尤其是两栖动物。
