A checklist of the fishes of the Coto River basin, southern Pacific, Costa Rica, compiled from field and museum surveys is presented. A total of 61 species, representing 48 genera, 26 families and 11 orders are listed. Peripheral species were dominant (44.3%), whereas secondary and primary freshwater species represented 32.8% and 23.9% of the total diversity. The orders Cyprinodontiformes (12 spp.) and Perciformes (11) and the families Poeciliidae (8) and Cichlidae (7) were the most diverse. Two species (Lutjanus guttatus and Polydactylus approximans) were new records for Costa Rican freshwaters and ten additional species were found to have expanded geographical ranges. An identification key and a complete photographic album of all fish species recorded are presented. This investigation provides a framework for future studies on fishes from this area complementing previous efforts seeking to increase our knowledge about the freshwater ichthyofauna of the central and southern Pacific regions of Costa Rica.
本文呈现了一份基于实地考察和博物馆调查编制的哥斯达黎加南部太平洋科托河流域鱼类清单。共列出61个物种，分属48个属、26个科和11个目。边缘物种占主导地位（44.3%），而次生淡水物种和原生淡水物种分别占总多样性的32.8%和23.9%。鲤齿目（12种）和鲈形目（11种）以及花鳉科（8种）和丽鱼科（7种）是多样性最高的类群。两种鱼类（黄点笛鲷和近似多指马鲅）是哥斯达黎加淡水水域的新记录物种，另有10个物种的地理分布范围有所扩大。文中给出了一份鉴定检索表以及所有记录鱼类物种的完整相册。本研究为该地区未来的鱼类研究提供了一个框架，补充了此前旨在增进我们对哥斯达黎加中太平洋和南太平洋地区淡水鱼类区系了解的工作。
