The occurrence of the species of the genus Brycon (Characiformes: Bryconidae) in Esprito Santo State is herein reviewed. Brycon opalinus, a species formerly known only from the upper rio Paraba do Sul and upper rio Doce basins, is recorded for the first time in the rio Itapemirim, an independent coastal basin in southern Esprito Santo State, Brazil. With the records of B. opalinus, four Brycon species are now known from Esprito Santo State: B. insignis in the rio Itabapoana basin, on the boundary between Rio de Janeiro and Esprito Santo, B. opalinus in the rio Itapemirim basin, B. dulcis in the rio Doce basin, and B. ferox in the rio Barra Seca, rio Itanas and the rio So Mateus basins. Additionally worth highlighting is that several fisherman and local inhabitants report the occurrence Brycon vermelha in the rio Cotax, a tributary of the rio So Mateus in Esprito Santo and Minas Gerais states, although there are no preserved specimens of B. vermelha from river basins other than the rio Mucuri, in Minas Gerais state.
本文回顾了巴西圣埃斯皮里图州的鱂形目鱂科鱂属物种的发生情况。Brycon opalinus 以前仅在帕拉巴苏尔河上游和多西河上游流域被发现，现首次在伊塔佩米林河（巴西圣埃斯皮里图州南部的一个独立沿海流域）被记录。随着 B.opalinus 的记录，现在有 4 种 Brycon 物种被记录在圣埃斯皮里图州：位于里约热内卢州和圣埃斯皮里图州边界的伊塔巴波拉纳河流域的 B.insignis，伊塔佩米林河流域的 B.opalinus，多西河流域的 B.dulcis 和巴雷拉塞卡河、伊塔纳斯河和索马泰乌斯河流域的 B.ferox。此外，值得注意的是，一些渔民和当地居民报告在圣埃斯皮里图州和米纳斯吉拉斯州的索马泰乌斯河支流科塔克斯河有 Brycon vermelha 的存在，尽管在米纳斯吉拉斯州的穆库里河流域以外，没有 B.vermelha 的标本。
