3. Diplonevra taigaensis Michailovskaya (Figs. 9–11, 19) Diplonevra taigaensis Michailovskaya, 1990: 697. Diplonevra bifalgella Lee et al., 2022: 243 (syn. n.). Michailovskaya (1990) described this species from Primorskii Krai of Russia. Later, she (2000) drew the figures of posterior face of hind femur and trochanter and male terminalia. Liu and Yang (2016) recorded its distribution in Northeastern China. Lee et al. (2022) found similar species in South Korea and considered that the Chinese specimens were not D. taigaensis Michailovskaya, because the specimens are with bifurcated setae on trochanter. They described it as new to science, D. biflagella. Recently, the first author (GCL) has gotten the photos of holotype given kindly by Dr. Ovchinnikova from the Zoological Institute of Russian Academy of Sciences (St. Petersburg). We compared our specimens with the holotype and figures in Michailovskaya (2000) in detail. The upper two setae of posterior face of holotype (Figs. 10–11) are thick and curved and clearly same as our specimens in China (Fig. 9). When we magnified the setae, we can see the bifurcated characters (Fig. 19). Now we formally conclude that the specimens in China belong to D. taigaensis and D. biflagella Lee et al. is a junior synonym of D. taigaensis. The species is widely distributed in Northeastern China. Distribution. China (Heilongjiang, Jilin, Liaoning, Beijing); Russia, South Korea.
