Huo, Qingbo, Du, Yuzhou, Zhu, Binqing & Yu, Lei, 2021, Notes on Neoperla sinensis Chu, 1928 and Neoperla anjiensis Yang & Yang, 1998 with descriptions of new species of Neoperla from China (Plecoptera: Perlidae), Zootaxa 5004 (2), pp. 288-310 : 304

Neoperla anjiensis Yang & Yang, 1998

( Figs. 26–31 )

Neoperla anjiensis Yang & Yang 1998: 43 ; Li, Liang & Li 2013: 354 .

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 ).
