Abstract

Abstract 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.

首次详细描述femorata Cinticostella成虫和若虫（Tshernova，1972）（蜉蝣目：蜉蝣科）

摘要本文首次报道了2020年春季从成熟若虫中饲养的星历蝇(Cincticostella femorata, Tshernova, 1972)(蜉蝣目:蜉蝣科)的成虫。与已知的同属雄性相比，特别是与C. fusca (Kang and Yang, 1995)相比，C. femorata雄性成虫的阴茎更简单，但衍生出的钳和翅膀更多。此外，我们首次提供了详细的若虫描述。若虫扁平流线型的身体，粗大锯齿状的股骨，不仅是其完美的诊断特征，而且具有在基质表面生存的适应性结构。

期刊介绍： Aquatic Insects is an international journal publishing original research on the systematics, biology, and ecology of aquatic and semi-aquatic insects. The subject of the research is aquatic and semi-aquatic insects, comprising taxa of four primary orders, the Ephemeroptera, Odonata, Plecoptera, and Trichoptera but also aquatic and semi-aquatic families of Hemiptera, Coleoptera, and Diptera, as well as specific representatives of Hymenoptera , Lepidoptera, Mecoptera, Megaloptera , and Neuroptera that occur in lotic and lentic habitats during part of their life cycle. Studies on other aquatic Hexapoda (i.e., Collembola) will be only accepted if space permits. Papers on other aquatic Arthropoda (e.g., Crustacea) will not be considered, except for those closely related to aquatic and semi-aquatic insects (e.g., water mites as insect parasites). The topic of the research may include a wide range of biological fields. Taxonomic revisions and descriptions of individual species will be accepted especially if additional information is included on habitat preferences, species co-existing, behavior, phenology, collecting methods, etc., that are of general interest to an international readership. Descriptions based on single specimens are discouraged. Detailed studies on morphology, physiology, behavior, and phenology of aquatic insects in all stadia of their life cycle are welcome as well as the papers with molecular and phylogenetic analyses, especially if they discuss evolutionary processes of the biological, ecological, and faunistic formation of the group.
