本文首次描述和拍摄了2020年春季从成熟若虫中饲养出的粉纹夜蛾Cincticoella femorata(Tshernova，1972)的成虫。与同属中已知的雄性，特别是Fusca(Kang和Yang，1995)相比，该属的雄性成虫有更简单的阴茎，但有更多的钳子和翅膀。此外，我们还首次提供了详细的若虫描述。若虫扁平流线型的身体和粗大锯齿状的股骨不仅是其完美的诊断特征，而且还假定它们的适应结构生活在底物表面。
The adults of Cincticostella femorata (Tshernova, 1972) (Ephemeroptera: Ephemerellidae), which were reared from mature nymphs in spring 2020, are described and photographed for the first time. Compared to the known males in the same genus, especially C. fusca (Kang and Yang, 1995), the male adults of C. femorata have simpler penis but more derived forceps and wings. Additionally, for the first time, we provided detailed nymphal description. A flat and streamline body, enlarged and serrated femora of nymphs are not only their perfect diagnostic characters but also assumed their adaptive structures to live on substrate surface.
