Diagnosis. Neopanorpa quadristigma sp. n. can be readily differentiated from its congeners by the following characters: (1) Wings hyaline with grayish markings, bearing unique black rectangular stripe on pterostigma ( Fig. 16a & b View FIGURE 16 ); (2) notal organ very short and stout, extending not beyond third length of T4, with hirsute truncated apex ( Fig. 16e View FIGURE 16 ); (3) Male A7–A8 pale, male genitalia black ( Fig. 16f View FIGURE 16 ); (4) ventral valve of aedeagus bifurcated into hook-like apices, expanded laterad into a broad triangular shape ( Fig. 17a–c View FIGURE 17 ); (5) female genital plate with a broad main plate, axis extending anteriorly beyond main plate for half length, posterior arms spatulate ( Fig. 17e–g View FIGURE 17 ).

Etymology. The specific name is derived from Latin quadri (quadrate) and stigma (stigma), referring to the conspicuous black pterostigma.

Description. Holotype ( Figs. 2b View FIGURE 2 & 16a View FIGURE 16 ).

Head ( Fig. 16c View FIGURE 16 ). Vertex and ocellar triangle black. Rostrum pale yellowish with blackish brown longitudinal stripe along clypeus, abruptly narrowed at base.

Thorax ( Fig. 16d View FIGURE 16 ). Pronotum blackish brown. Mesonotum black at anterior half, extending caudad as diffuse blackish brown median stripe to scutellum, leaving sooty yellowish brown areas adjacent to wing base; metanotum with similar pattern.

Wings ( Fig. 16a View FIGURE 16 ). Wings membrane hyaline with grayish markings; R2 bifurcated. Wing markings faintly indicated by obscure shadow-like markings, with a prominent black stripe on pterostigma. In forewings, apical band indicated by several scattered shadow-like markings; pterostigmal band broad, forked posteriorly into two branches; submedian band long and curved, interrupted in the middle; marginal spot small between Rs and R1. Hindwings only with a black stripe on pterostigma.

Abdomen. T1–T5 grayish black ( Fig. 16a & e View FIGURE 16 ). Male A6 black, A7–A8 pale ( Fig. 16f View FIGURE 16 ). Notal organ stout, only slightly projected caudad, with hirsute truncate apex; T4 membranous anteriorly, bearing hirsute flat post-notal organ ( Fig. 16e View FIGURE 16 ).

Male genitalia. Blackish brown. Hypandrium with basal stalk slightly longer than hypovalves; hypovalves with apical half membranous, extending to median tooth of gonostylus, strongly twisted ventro-mesad at apices, hypandrial processes absent ( Fig. 16g View FIGURE 16 ); in lateral aspect, hypovalves expanded dorsad into broad subtriangular shape ( Fig. 16i View FIGURE 16 ). Epandrium tapering toward apex, with membranous truncate apex ( Fig. 16h View FIGURE 16 ), bearing a pair of broad rectangular epandrial lobes apically ( Fig. 16i View FIGURE 16 ). Gonostylus dark brown, median tooth blunt; basal lobe cuplike, strongly concave ( Fig. 16j & k View FIGURE 16 ). Ventral valve of aedeagus bifurcated and forming hook-like processes at apex, projected ventrad, expanded laterad broadly, ending with a triangular apex; dorsal valves stout, concealed in ventral aspect ( Fig. 17a–c View FIGURE 17 ). Paramere with a long basal stalk, and bifurcated distally into ventral branch and dorsal branch; ventral branch with pointed apex projecting ventro-mesad and overlapping its counterpart mesally; dorsal branch slender and long, elongated dorso-laterad; lateral process greatly expanded, curved ventro-mesad, with pointed apex; dorsal process absent ( Fig. 17a–c View FIGURE 17 ).

Female (Paratype) ( Fig. 16b View FIGURE 16 ). Similar coloration as in the male. T1–T9 blackish brown ( Fig. 16b View FIGURE 16 ). Wing markings more extensive due to complete apical band with one hyaline window anteriorly and one posteriorly in forewings. Subgenital plate broad oval-shaped, with shallow V-shaped emargination at apex ( Fig. 17d View FIGURE 17 ). Genital plate with axis extending anteriorly beyond main plate for its half length, slightly forked proximally; posterior arms spatulate, twisted and abruptly narrowed subbasally ( Fig. 17e–g View FIGURE 17 ).

Measurements. Male (n = 5), forewing length 12.06 ± 0.69 mm, width 3.05 ± 0.16 mm; hindwing length 11.07 ± 0.59 mm, width 2.87 ± 0.14 mm. Female (n = 9), forewing length 11.95 ± 0.65 mm, width 2.98 ± 0.14 mm; hindwing length 10.91 ± 0.66 mm, width 2.76 ± 0.15 mm.

Remarks. The new species resembles N. uncata Zhou, 2000 in male genitalia, but differs from the latter by its extremely short notal organ and wing markings.
