03D8878DFFC1DE5384E5FCADA048310D.taxon	diagnosis	Diagnosis. Sinacroneuria complana sp. nov. is similar to S. acuticornis Uchida, 2017 by sharing similar structural characteristics of the aedeagal Y-arms. The lateral sclerites of aedeagus of S. complana are slender and nearly equal to the Y-arms (Fig. 2 e), while that in S. acuticornis are shorter and about 1 / 2 length of the Y-arms (Figs. 42 – 44 in Li et al. 2017). Additionally, the tergum 9 sensilla basiconica patch of S. complana (Fig. 2 d) is markedly sparser compared to S. acuticornis (Fig. 38 in Li et al. 2017). Sinacroneuria complana sp. nov. is also easily separated from S. lateralis Sivec & Stark, 2020. The apex of Y-arms in S. lateralis (Fig. 1 g in Sivec & Stark 2020) are more separated from each other yet closed to each other in S. complana (Fig. 2 e).	en	Xiang, Ya-Nan, Huo, Qing-Bo, Du, Yu-Zhou (2022): Three new species of Sinacroneuria Yang & Yang, 1995 (Plecoptera: Perlidae) from Zhejiang Province, southeastern China.
