Two new species of Characidium, C. tatama and C. dule, are described from the biogeographic Chocó region in western Colombia. Both new species are supported by both morphological and molecular data. C. tatama from the San Juan River in the Pacific and C. dule from the Atrato River in the Caribbean portion of Colombia are both distributed in the upper and lower portions of these basins. An extensive comparison with other trans- and cis-Andean species of Characidium was made, in addition to species delimitation, using COI sequences by distinct methods (GMYC, ABGD, bPTP).
两种新的Characidium 物种，即 C. tatama 和 C. dule，来自哥伦比亚西部具有生物地理意义的 Chocó 地区。这两个新物种都得到了形态学和分子数据的支持。来自太平洋圣胡安河的 C. tatama 和来自加勒比地区 Atrato 河的 C. dule 均分布于这些流域的上下游。除了使用 COI 序列通过不同方法（GMYC、ABGD、bPTP）进行物种划分外，还与其他跨安第斯山脉和安第斯山脉内的 Characidium 物种进行了广泛的比较。
