Material examined. 2♂, CHINA: Yunnan: Tengchong County: Menglian (elev. 970 m), 25.v.2011, leg. Lin Lyu   ; 3♂ 3♀, CHINA: Yunnan: Ruili County: Ruili Botanical Garden (1240–1450 m), 01.vii.2007, leg. Li-Jun Cai   .

Diagnosis. Neopanorpa spatulata   can be readily distinguished from its congeners by the following characters: (1) Wing markings peculiar by pterostigmal band with very broad basal branch running obliquely to posterior margin; (2) male hypandrium with very broad basal stalk; hypovalves broad oval-shaped, broadly expanded and overlapped mesally.

Measurements. Male (n = 4), forewing length 14.21 ± 0.44 mm, width 3.27 ± 0.22 mm; hindwing length 12.70 ± 0.75 mm, width 3.07 ± 0.10 mm. Female (n = 2), forewing length 13.85 ± 0.11 mm, width 3.25 ± 0.04 mm; hindwing length 12.32 ± 0.11 mm, width 2.98 ± 0.12 mm.

Distribution. Neopanorpa spatulata   was reported previously from Thailand ( Byers, 1965). This is the first distributional record from China.

Remarks. Our material shows several differences from Byers’ original descriptions. First, the wings are tinged with yellowish grey in the original descriptions, but are hyaline in the Chinese specimens. Second, the dorsal parameres mentioned in the original description were not observed in the present investigation. The ventral branch of paramere extends beyond the lateral process, not lower than the lateral process as in original illustration ( Fig. 19a –c View FIGURE 19 ). Moreover, based on our photographs, the subgenital plate has a deep V-shaped emargination at apex, not a shallow cleft as in the original description ( Fig. 19d View FIGURE 19 ). Despite the differences observed, several similarities indicate the conspecificity of the Thai and Chinese specimens, namely the oval-shaped hypovalves, notal organ shape, wing markings, and the form of the female genitalia.
