This study constitutes the most comprehensive effort ever done to assess the faunal diversity of the Macrobrachium genus within two ecoregions that encompass part of the northeastern Brazil: the Northeastern Caatinga Coastal Drainages, and the São Francisco (Lower-middle and Lower portions). Through sampling in several of their hydrographic basins, bibliographic research, and consulting scientific collections, our results reveal the occurrence of five species along these ecoregions: Macrobrachium acanthurus, M. amazonicum, M. carcinus, M. jelskii and M. olfersii. We also provide the first record of these species for several river basins in both ecoregions. Additionally, we confirm the occurrence of M. carcinus from Rio Grande do Norte State and provide updated distribution maps for each species in the studied area. This carcinofauna survey may form the basis for future evaluations of eventual anthropic impacts on biological diversity resulting from projects being implemented in these regions, which involve the São Francisco interbasin water transfer.
这项研究是迄今为止对涵盖巴西东北部部分地区的两个生态区中的Macrobrachium 属动物群多样性进行的最全面评估：东北卡廷加沿海流域和圣弗朗西斯科（中下和下游）。通过在这些流域中的几个流域进行采样、文献研究和咨询科学收藏，我们的结果表明，在这些生态区中存在着五种物种：M. acanthurus、M. amazonicum、M. carcinus、M. jelskii 和 M. olfersii。我们还首次记录了这些物种在两个生态区的几个河流流域中的存在。此外，我们证实了 M. carcinus 在北里奥格兰德州的存在，并为研究区域内的每个物种提供了更新的分布地图。这项甲壳动物调查可能为未来评估这些地区实施的项目对生物多样性的潜在人为影响提供基础，这些项目涉及圣弗朗西斯科流域间调水。
