Neoperla yangae Du, 2001 in Wu & Pan 2001: 79. (syn. fide Li et al. 2013). Material examined: 5♂♂ ( ICYZU ), China , Anhui Province , Huangshan City , Mt. Huangshan , “the Valley of Wild Monkeys”, 597m , 30°5′11.508″N , 118°8′29.7816″E , 2020– VI –2, leg. Yu Lei. Diagnosis: The aedeagus agrees well with the original illustration in Du et al. (2001) (Li et al. 2013). Aedeagal tube sclerotized, evenly curved ventrally, with many spines on dorsal surface and a dark bevelled ring proximally. Aedeagal sac shorter than tube (ca. 1/6 tube length), membranous, gradually tapering to a blunt tip and strongly curved ventrally forming nearly a right angle with tube; dorsally covered by dense spines; ventrobasal surface smooth ( Figs. 29–30 ). Distribution: China ( Zhejiang and Anhui Provinces) ( Fig. 31 ). Remark: Compared with the individuals in Zhejiang , our materials from Anhui showed differences between individuals including the procces on male tergum 8 with or without an anterior notch, and the hemitergal process sometimes obviously slender. Their aedeagal morphology without visible difference in this study ( Fig. 28 ).
