The knowledge of the Costa Rican freshwater fish fauna continues to grow given the discovery of new taxa, the recognition of taxa resurrected from synonymy and the corroboration of new country records and new range extensions. Moreover, recent advances in the understanding of the phylogenetic relationships and status of many supraspecific groups have led to numerous taxonomic and nomenclatural changes. Given this, the purpose of this paper is to update the known composition, distribution and clasification of the Costa Rican freshwater fish fauna taking as reference the most recent list for the country published by Angulo et al. (2013). A total of 23 new country records (i.e., species; distributed in 17 families and 21 genera), 33 new range extensions (distributed in 20 families and 30 genera) and several nomenclatural changes are reported, illustrated and discussed here. An updated and annotated checklist of the freshwater fishes of the country (including data for a total of 283 species, 13 of which are exotic, distributed in two classes, 27 orders, 55 families and 136 genera) is also provided.
哥斯达黎加淡水鱼类区系的知识不断增加，新分类单元的发现、从同义词中重新确认分类单元以及新的国家记录和新分布范围的证实都起到了推动作用。此外，对许多超种群系统发育关系和地位的理解的最新进展也导致了大量的分类和命名变化。有鉴于此，本文旨在根据 Angulo 等人（2013 年）发表的哥斯达黎加最新鱼类名录，更新已知的哥斯达黎加淡水鱼类区系的组成、分布和分类。共记录了 23 个新的国家记录（即物种；分布于 17 科 21 属）、33 个新的分布范围扩展（分布于 20 科 30 属）和一些命名变化，并在此进行说明和讨论。本文还提供了该国淡水鱼类的更新和注释清单（包括总共 283 种的数据，其中 13 种是外来种，分布在两个纲、27 个目、55 科和 136 属）。
