Neoperla magisterchoui Du, 2000 . In: Zhang Y.L. (Ed). Systematic and faunistic research on Chinese insects. Proceedings of the 5th National Congress of Insect Taxonomy: 1. Type locality: Shaanxi, Ningshan, Xunyangba.

Diagnosis. This species is characterized by a trapezoidal dark median area on the head ( Fig. 6 ) and by two pairs of ventral and lateral spinose projections and an additional transverse band of spinules connecting the two lateral ones on the aedeagal tube ( Figs. 8–10 ). The everted sac has a transverse band of small spines at midlength ( Figs. 9, 10 ) and a dorsal, longitudinal row of small spines apically that fuse into a spinule patch distally ( Figs. 10, 11 ).

Female. Unknown.

Remarks. We did not examine the types of the species, but the color pattern and aedeagal structures of our specimens agree well with descriptions of Du (2000), except that the lateral spinulose projections on the aedeagal tube are less prominent in the type, possibly due to its condition. Additionally, the bell-shaped apex is not extruded in Du’s illustration.

Material examined. 2 males, China: Henan Province, Song County, Lishujie village, 2008. VI.18, 34.1378 N, 112.0828 E, Jianxin Cui.

Distribution. China (Henan, Shaanxi).
