Five Filchneria Klapálek, 1908 (Plecoptera, Perlodidae) species known since the last century (F. balcarica Balinsky, F. mesasiatica Zhiltzova, F. irani (Aubert), F. kuenluensis (Šámal), and F. olgae (McLachlan)) were redescribed on types stored in museums in the Netherlands, Switzerland, Russia and newly acquired material. The redescription were in accordance with the requirements of modern taxonomy, illustrated with color photographs of the habitus, head, pronotal patterns, eversible male paraproct lobes, male paraproctal sclerite, aedeagus (as possible), details of chaetotaxy, female subgenital plate, and egg using digital cameras and SEM. The diagnostic features of each species are revealed. The main differences were established in the male paraproctal sclerite shape, in the posterior margin of tergum 10, the female subgenital plate, and the egg structures. After reexamining the syntype series of Filchneria olgae, a lectotype is designated for this species. Filchneria kuenluensis is proposed to transfer to Perlodinella Klapálek, 1912 with the valid name Perlodinella kuenluensis (Šámal, 1935) comb. nov. Filchneria shobhaae is considered as a junior synonym of Zhiltzovaia amabilis (Jewett, 1958) syn. nov.
上个世纪以来，已知有五种 Filchneria Klapálek，1908（蜉蝣目，褶翅蜉科）物种（F. balcarica Balinsky、F. mesasiatica Zhiltzova、F. irani (Aubert)、F. kuenluensis (Šámal) 和 F. olgae (McLachlan)），它们的模式标本保存在荷兰、瑞士、俄罗斯的博物馆中，以及新采集的材料。本研究根据现代分类学的要求对这些模式标本进行了重新描述，并附有彩色照片，展示了它们的整体形态、头部、前胸背板图案、可翻出的雄性肛下叶、雄性肛下附器骨片、阳茎（如有）、毛序细节、雌性生殖下板和卵，这些图片是使用数码相机和 SEM 拍摄的。揭示了每个物种的鉴别特征。主要区别在于雄性肛下附器骨片的形状、第 10 背板后缘、雌性生殖下板和卵的结构。在重新检查了 Filchneria olgae 的模式系列后，指定了该种的一个正模。Filchneria kuenluensis 被提议转移到 Perlodinella Klapálek，1912，其有效名称为 Perlodinella kuenluensis (Šámal, 1935) comb. nov.。Filchneria shobhaae 被认为是 Zhiltzovaia amabilis (Jewett, 1958) syn. nov.的一个次同物异名。
