The genus Zungaro contains some of the largest catfish in South America. Two valid species are currently recognized: Zungaro jahu, inhabiting the Paraná and Paraguay basins, and Zungaro zungaro, occurring in the Amazonas and Orinoco basins. Analysing Zungaro specimens from the Amazonas, Orinoco, Paraguay and Paraná basins, based on the sequencing of COI and D-loop, we found at least three MOTUs, indicating the existence of hidden diversity within this fish group. Considering the ecological and economic values of this fish, our results are surely welcomed for its conservation, disclosing new findings on its diversity and pointing out the necessity for a detailed taxonomic revision.
宗加罗属包含了一些南美洲最大的鲶鱼。目前已确认有两个有效物种：栖息于巴拉那河和巴拉圭河流域的雅胡宗加罗鲶，以及分布在亚马逊河和奥里诺科河流域的宗加罗鲶。通过对来自亚马逊河、奥里诺科河、巴拉圭河和巴拉那河流域的宗加罗鲶标本进行细胞色素氧化酶亚基I（COI）和控制区（D-loop）测序分析，我们发现至少有三个分子操作分类单元（MOTUs），这表明该鱼类群体中存在隐藏的多样性。鉴于这种鱼的生态和经济价值，我们的研究结果无疑有助于其保护工作，揭示了关于其多样性的新发现，并指出了进行详细分类修订的必要性。
