038D87DE636DFFC2FF37EA074F0AFD36.taxon	discussion	Remarks: This species was reported for the first time by Stark & Sivec (2009) from Sichuan Province, Pitiao River, Balangshan Pass. According to Stark & Sivec (2009), this species is closely related to Haploperla lepnevae and H. ussurica Navás, 1934, formerly reported from northeastern China. Both species have triangular-shaped epiproct with narrow tips but are easily distinguished from H. valentinae based on epiproct structure and aedeagus. We agree with Stark & Sivec (2009) that this species is closely related to the above two species. Besides these species, we found that the morphology of H. triangulata and H. datongensis, especially the epiproct and body pigmentation, are also closely similar to H. valentinae. For confirmation, we checked the type materials of H. datongensis (Fig. 4 A – D) and H. triangulata (Fig. 5 A – D) from Qinghai Province (Chen & Du 2016 a, Chen & Du 2016 b) present at ICYZU. We found that the holotype morphology of both species is similar to the H. valentinae (Fig. 1 A – F). It is worth noting that the male of these species exhibits some minor differences, namely that the posterodorsal area of the epiproct of H. valentinae (see Stark & Sivec, 2009: figs. 12 – 13) and H. datongensis (Fig. 4 B) bear a sparse patch of short setae while the holotype of H. triangulata (Fig. 5 B) and the specimens collected from Sichuan Province (Fig. 1 B – C) have fewer setae, which are not obvious. We found that the aedeagus of the holotypes of H. datongensis and H. triangulata (Figs. 4 C, 5 C – D) are the same as the H. valentinae collected from Sichuan Province (Fig. 2 A – E). The illustration of aedeagus in the description of Chen & Du (2016 a, figs. 5 – 6; 2016 b, figs. 15 – 16) lacks some essential morphological characters. On the other hand, there is no aedeagus description present in the description of Stark & Sivec (2009), which mislead the identification of these species in the past. The female subgenital plate of H. valentinae (Fig. 3 C) and H. datongensis (Fig. 4 D) are similar, but the subgenital plate of H. triangulata extends more posteriorly (Fig. 5 E). This minute morphological difference maybe due to age, environment, or individual differences. Thus, we provide the detailed revised description of the H. valentinae Stark & Sivec (2009) from Sichuan Province with new images illustration, with H. triangulata and H. datongensis placed as new synonyms. Haploperla valentinae is widely distributed from northwestern Sichuan to Qinghai Province (Fig. 9).	en	Rehman, Abdur, Huo, Qing-Bo, Du, Yu-Zhou (2022): Two new synonyms of Haploperla valentinae Stark & Sivec, 2009 and supplementary redescription of H. tuanjiena Chen & Du, 2016 from western China.

038D87DE6369FFC1FF37EE0F4E7FFF34.taxon	materials_examined	Material examined: We re-checked and redescribed the type material of Chen & Du (2016 b). The type locality is Sichuan Province, Kangding, Xinduqiao, N 30.0738, E 101.8313, 3461 m (Fig. 9). Male: Body length 5.5 – 6.0 mm, forewing length 6.0 – 6.5 mm, hindwing length 5.5 – 6.0 mm (n = 5). Medium-sized Haploperla. Triocellate, Body color is pale yellow; head yellowish and intraocellar area light brown; compound eyes dark black. Pronotum yellow, posteriorly and anteriorly with a brown stripe on a disc (Fig. 6 A). Tergum 9 posterior margins were slightly plump and covered with hairs. Tergum 10 divided, median portion forming a triangular structure to the base of epiproct. Epiproct subtriangular in dorsal view, inflated in lateral view, and anterolateral margin strongly sclerotized; posterodorsal area membranous; apex of epiproct sharp (Fig. 6 B – D). Aedeagus enlarged, membranous rounded, dorsally covered with scattered small spines, ventrolaterally with a pair of sclerotized stylus and with a patch of sclerotized spines, the patch of spines in ventral view look like ear-shape on both sides (Fig. 7 A – D). Female: Body length 7.0 mm, forewing length 7.5 mm, hindwing length 6.0 mm (n = 1). Head, pronotum disk, body color and pattern similar to males (Fig. 8 A). Terga 1 – 8 dorsally with large oval, brownish spots medially (Fig. 8 B). The small subgenital plate originating from tergum 8, the posterior margins are bluntly rounded (Fig. 8 C – D).	en	Rehman, Abdur, Huo, Qing-Bo, Du, Yu-Zhou (2022): Two new synonyms of Haploperla valentinae Stark & Sivec, 2009 and supplementary redescription of H. tuanjiena Chen & Du, 2016 from western China.

038D87DE6369FFC1FF37EE0F4E7FFF34.taxon	discussion	Remarks: According to Chen & Du (2016 b), this species is closely related to H. maritima Zhiltzova & Levanidova, 1978, known from the Russian Far East and H. longicauda Zwick, 1977 from Bhutan. Herein, we add that this species is also close to H. choui Li & Yao, 2013 reported from Shaanxi, Qinling Mountains. The head and pronotum of H. choui are darkly pigmented (see Li et al. 2013: figs. 3, 4), which is different from H. tuanjiena, but the epiproct and aedeagus are close to H. tuanjiena. The aedeagus of H. choui is also with a pair of stylus ventrolaterally, but a band of dense setae is present in the dorsal aspect. This band of dense setae is not present in H. tuanjiena; the head and pronotum are also not darkly pigmented (Figs. 6 A – D, 7 A – D), which easily differentiates these species. In the original description of Chen & Du (2016 b), the plates are not obvious, especially with regards to the epiproct and which may lead to misidentification in the future. The dorsal scattered spines on aedeagus and obvious lateral scales are absent (see Chen & Du, 2016 b: figs. 4 – 6). Therefore, we redescribed and gave good quality plates of epiproct and aedeagus with complete morphological characters and descriptions to avoid confusion in the future.	en	Rehman, Abdur, Huo, Qing-Bo, Du, Yu-Zhou (2022): Two new synonyms of Haploperla valentinae Stark & Sivec, 2009 and supplementary redescription of H. tuanjiena Chen & Du, 2016 from western China.
