A new species of Limnophyes Eaton collected in the Corvo Branco Mountains in Santa Catarina State is described and figured, based on male and female adults, larva and pupa. The species groups with L. griseata (Edwards) and L. bidumus Sæther as the adults have a pronounced humeral pit with lanceolate setae and an additional group of lanceolate setae just posterior to antepronotum. The adults are, however, distinctly smaller, have a lower AR and have more lanceolate setae in the group just posterior to antepronotum than the two other species. The pupa can easily be separated from the pupa of L. bidumus as the anal macroseta is longer than the anal lobe. The larva lives hygropetric on vertical rock surfaces. A key to male adults of Neotropical Limnophyes is given.
基于成年雄性和雌性、幼虫及蛹，描述并图示了在圣卡塔琳娜州科沃布兰科山脉采集到的一种新的伊顿摇蚊属物种。该物种与灰伊顿摇蚊（爱德华兹）及双瘤伊顿摇蚊归为一组，成虫具有明显的肩窝，有披针形刚毛，且在前胸背板后方还有一组披针形刚毛。然而，该成虫明显更小，翅脉比更低，且在前胸背板后方的组中比其他两个物种有更多披针形刚毛。其蛹可轻易与双瘤伊顿摇蚊的蛹区分开，因为肛大刚毛比肛叶长。该幼虫生活在垂直岩石表面的喜湿环境中。给出了新热带伊顿摇蚊属雄性成虫的检索表。
