A new species with primitive characteristics, Tong, , is described, based on the morphology of imago, larva and egg with molecular data of the mitochondrial COI from Mount Cangshan, Dali, China. The new species is closely related to one of the most primitive mayflies, Traver, 1939, by sharing persistent mouthparts in the alate stage, but it can be distinguished from the latter by the morphological differences of the mouthpart remains, wings and genitals in the imaginal stage. Both morphological and molecular evidence support that Tong, is a new member of the genus . The discovery of the new species could help understand the origin and evolution of the genus .
基于采自中国大理苍山的成虫、幼虫和卵的形态以及线粒体细胞色素氧化酶亚基I（COI）的分子数据，描述了一个具有原始特征的新物种——Tong。该新物种与最原始的蜉蝣物种之一Traver（1939）关系密切，在有翅阶段具有持久的口器，但在成虫阶段，可通过口器残迹、翅膀和生殖器的形态差异与后者区分开来。形态学和分子证据均支持Tong是该属的一个新成员。新物种的发现有助于理解该属的起源和演化。
