Bopyrid isopods of the genus Probopyrus are well-known parasites of freshwater prawns of the genus Macrobrachium. The parasitism of coastal populations of Macrobrachium amazonicum by Probopyrus bithynis, for example, has been documented since the late 1980s. Despite this, molecular data on different populations are not available for any Probopyrus species. The present study is the first to describe Probopyrus populations from distinct regions of the Amazon basin based on sequences of two genes, the mitochondrial cytochrome oxidase C subunit I (COI) and the nuclear 18S ribosomal DNA (18S rDNA) gene. The analyses indicated the presence of two Probopyrus species, each parasitizing either the coastal or the inland populations of M. amazonicum. The results indicated the potential use of the COI barcode for the identification of Probopyrus species. We discuss the potential implications of the findings for the taxonomy of Probopyrus bithynis and other species of the genus Probopyrus.
双栉大眼鲷属的 Bopyrid 等足目是淡水长臂虾属 Macrobrachium 的知名寄生虫。例如，自 20 世纪 80 年代末以来，就有记录表明，双栉大眼鲷属的 Probopyrus bithynis 寄生在沿海的亚马逊河大长臂虾 Macrobrachium amazonicum 群体中。尽管如此，任何 Probopyrus 物种的不同种群的分子数据都不可用。本研究首次根据线粒体细胞色素氧化酶 C 亚基 I（COI）和核 18S 核糖体 DNA（18S rDNA）基因的两个基因序列，描述了来自亚马逊河流域不同地区的 Probopyrus 种群。分析表明存在两种 Probopyrus 物种，每种寄生虫分别寄生在沿海或内陆的亚马逊河大长臂虾 Macrobrachium amazonicum 群体中。结果表明，COI 条码可用于鉴定 Probopyrus 物种。我们讨论了这些发现对 Probopyrus bithynis 和其他 Probopyrus 属物种的分类学的潜在影响。
