Yao Zhou; allotype, 1 female (IZCAS), same locality and date as for holotype.</p><p>Remarks. Perlodinella kozlovi was redescribed recently based on the type series from Sichuan and newly collected specimens from Qinghai (Huo et al. 2022b). We also checked the newly designated types of P. kozlovi . Both the holotype male and female of P. tatunga Wu, 1973 appear identical with the types of P. kozlovi indicating they are conspecific.</p><p>The holotype of P. fuliginosa is faded after such a long period of preservation in ethanol. The holotype is quite similar to that of P. tatunga (now a subjective junior synonym of P. kozlovi) but the females are externally different (Fig. 1; figs. 68–75 in Wu 1973). The head pattern and terminalia of the two species also support our postulation that they may be conspecific (Figs. 2, 6a–d). The everted aedeagus that bears a pair of basolateral projections, a spinous medial section and bilobed, and a spineless apex (Figs. 3a–c) and the L-shaped epiproct (Fig. 3d) of the holotype are identical with P. kozlovi (see figs. 8c–e of Huo et al. 2022a). Perlodinella fuliginosa also shares a similar head pattern and terminalia to P. mazehaoi, however, further comparison is impossible because the epiproct and everted aedeagus of the species are still unknown.</p><p>As for the female allotype, we found the head pattern differs much as compared to the holotype (Fig. 4a), although the genital plate seems like a perlodid species (Fig. 4b). The female allotype likely belongs to a different species, even seemingly like a Perlidae because it lacks the typical head marking of a Perlodidae . Note that we considered another female paratype from Hebei Province as a Filchneria sp. (Fig. 5) and redescribe it below.</p><p>Perlodinella tatunga is a dark species but is now also much faded during the long preservation period in alcohol. The head pattern, terminalia, and female characters, however, still allow this species to be correctly identified (Figs. 6a–f), supporting our contention that this species is a subjective junior synonym of P. kozlovi as proposed by Huo et al. (2025).</p><p>Perlodes is primarily distributed in Europe and northern Asia and its distribution in China is thought to be questionable (Huo et al. 2022b). Our color images of the female allotype of P. tatunga (Figs. 6f, 7c) show an identical shape and color pattern of the female subgenital plate of Perlodes truncata (Fig. 7f), together with an identical time of emerging, indicating they are conspecific. After we examined the subgenital plate of the paralectotype female of Perlodinella kozlovi (Figs. 7a–b,) we found it is in full agreement with that of P. truncata (Fig. 7f). It also follows that P. truncata belongs to the genus Perlodinella . We propose to transfer P. truncata to Perlodinella and place P. truncata as a junior synonym of P. kozlovi syn. nov. Similarly, Perlodes lobata shares a similar subgenital plate with the original illustration of P. tatunga (Fig. 7d–e) and also fall in the variations among populations of P. kozlovi as discussed in Huo et al. (2022a). Therefore, we define Perlodes lobata herein as a junior synonym of Perlodinella kozlovi Klapálek, 1912 syn. nov.</p><p>Distribution.
