A new monotypic genus and species of predaceous midge from the southernmost area of the Argentinean Yungas, Yungahelea australis Spinelli and Ronderos, is described and illustrated from male and female adults. It belongs to a group containing the Ceratopogonini genera Parabezzia Malloch, Diaphanobezzia Ingram and Macfie, Spinellihelea Borkent, Grogan and Picado, Leptohelea Wirth and Blanton, and Fittkauhelea Wirth and Blanton. Phylogenetic interpretation indicates that Yungahelea is the sister group of Spinellihelea or the clade composed by Parabezzia and Diaphanobezzia.
描述并展示了来自阿根廷永加斯最南端地区的一种新的单型属和物种——南方永加斯蠓（Yungahelea australis Spinelli and Ronderos）的雌雄成虫。它属于一个包含角蠓科（Ceratopogonini）属的类群，这些属包括副贝氏蠓属（Parabezzia Malloch）、透贝氏蠓属（Diaphanobezzia Ingram and Macfie）、斯皮内利蠓属（Spinellihelea Borkent, Grogan and Picado）、细蠓属（Leptohelea Wirth and Blanton）以及菲特考蠓属（Fittkauhelea Wirth and Blanton）。系统发育分析表明，永加斯蠓属是斯皮内利蠓属或由副贝氏蠓属和透贝氏蠓属组成的进化枝的姐妹群。
