Material examined. 6♂ 5♀, CHINA: Yunnan: Yongde County: Dedang town (24°1′30″N, 99°15′15″E, elev. 1600 m), 24.viii.2014, leg . Ji-Shen Wang; 9♂ 15♀, CHINA: Yunnan: Yongde County: Tangli Mountain (24°01′17″N, 99°14′23″E, elev. 1400–2000 m), 26.vii.2015, leg . Ji-Shen Wang ; 2♂ 4♀, CHINA: Yunnan Province: Ximeng County (elev. 1230 m), 30.iv.2016 .

Diagnosis. Neopanorpa nielseni can be readily distinguished from its congeners by the following characters: (1) In wing markings, apical band notched posteriorly; pterostigmal band broad, slightly touching apical band along costal margin, apical branch sometimes absent or interrupted, basal branch narrowly constricted at base; (2) hypovalves extending beyond median tooth of gonostylus, the outer edges strongly infolded dorsad and the folded edges subparallel in ventral aspect.

Description. Female ( Fig. 2c ). T1–T6 black, A7–A9 yellowish brown ( Fig. 2c ). Subgenital plate broadly oval-shaped with V-shaped emargination ( Fig. 18d ). Genital plate with main plate projected laterad; axis not extending anteriorly beyond main plate; posterior arms spatulate-like, twisted and constricted at base ( Fig. 18e–g ).

Measurements. Female (n = 5), forewing length 16.49 ± 0.37 mm, width 3.77 ± 0.15 mm; hindwing length 14.72 ± 0.32 mm, width 3.52 ± 0.14 mm.

Remarks. The female of N. nielseni is described and illustrated here for the first time. The structure of aedeagus is also illustrated in ventral, lateral, and dorsal aspects ( Fig. 18a–c ).
