This paper presents an updated checklist of cartilaginous and bony fishes from the Revillagigedo Archipelago reefs and nearby areas (Tropical Eastern Pacific). To compile this list, we gathered data from field surveys between 1994 and 2015, from an exhaustive literature review, and by consulting museum collections and databases. With these records we estimated the completeness of the local fish inventory using four non-parametric rarefaction methods. We report a total of 389 species in 102 families; 235 of these are reef fish that occur in the Eastern but also in the Central Pacific, and 13 species were identified as endemic to the archipelago. A non-parametric statistical model predicts that the expected number of reef fish present at Revillagigedo should be 244.3 ± 3.2 species, which is 9 species more than the observed richness, and this difference was statistically significant (p = 0.02). That predictive model estimates that about 96% of the total richness of reef fish from the archipelago is known. Comparisons of the completeness of the inventory at Revillagigedo to that reported for the fish fauna of the Eastern Pacific and worldwide, showed that the quality of the sampling effort is remarkably high, in spite of the geographic isolation of the archipelago.
本文展示了一份关于雷维利亚希赫多群岛珊瑚礁及附近海域（热带东太平洋）软骨鱼和硬骨鱼的更新清单。为编制这份清单，我们收集了1994年至2015年间实地调查的数据、详尽的文献综述资料，并查阅了博物馆藏品和数据库。利用这些记录，我们采用四种非参数稀疏化方法估计了当地鱼类清单的完整性。我们报告了102个科的共计389种鱼类；其中235种是在东太平洋和中太平洋都有出现的珊瑚礁鱼类，还有13种被确定为该群岛特有的鱼类。一个非参数统计模型预测，雷维利亚希赫多群岛现存的珊瑚礁鱼类预期数量应为244.3 ± 3.2种，比观测到的丰富度多9种，且这种差异具有统计学意义（p = 0.02）。该预测模型估计，该群岛珊瑚礁鱼类总丰富度中约96%是已知的。将雷维利亚希赫多群岛清单的完整性与东太平洋和全球鱼类区系报告的完整性进行比较表明，尽管该群岛地理位置孤立，但抽样工作的质量非常高。
