A new species of Chydoridae cladoceran (Crustacea: Cladocera: Chydoridae) is described from the Cerrado (a Brazilian tropical savanna ecoregion), Central Brazil. Ephemeroporus quasimodo sp. nov. differs from other species of the genus in a high dorsal keel on carapace and posterior part of the head shield, which resembles a hunchback. Parthenogenetic females, ephippial females and males are described, including details of trunk limb morphology. The species is endemic to shallow wetlands found in the Cerrado, where pristine conditions are preserved. Some questions on genus morphology and taxonomic status of Ephemeroporus species occurring in Brazil are discussed.
本文描述了一种来自巴西中部塞拉多（巴西热带稀树草原生态区）的新种仙达溞科枝角类动物（甲壳纲：枝角目：仙达溞科）。拟驼背短腹仙达溞新种在头胸甲和头部盾板后部有一条高高的背龙骨，形似驼背，这使其与该属的其他物种有所不同。文中描述了孤雌生殖雌体、带卵鞍雌体和雄体，包括躯干肢形态的细节。该物种是塞拉多地区浅湿地的特有物种，这些湿地的原始条件得以保存。文中还讨论了巴西出现的短腹仙达溞属物种的形态学和分类地位的一些问题。
