LSID: urn: lsid: zoobank.org: act: A242377B-20D6-4BFB-AF0E-FC54 E79757 F2

Material examined. Holotype ♂, CHINA: Yunnan: Dali: Diancang Mountain (elev. 2200–2400 m), 08.vi.2014, leg. Chao Gao & Mei Liu, ME000138 ( NWAFU) . Paratypes 4♀, same data as holotype, ME000139 –ME000142 (NWAFU); 1♂, CHINA: Yunnan: Dali City: Diancang Mountain (elev. 2500 m), 01.viii.2015, leg. Ji-Shen Wang & Shuang Xue, ME000143 ( NWAFU) ; 1♂, CHINA: Yunnan: Baoshan: Daoren Mountain , 03.vi.2009, leg. Jiang-Li Tan, ME000144 ( NWAFU) .

Diagnosis. Neopanorpa longistipitata sp. n. can be readily differentiated from its congeners by the following characters: (1) Generally yellowish brown with unmarked wings ( Fig. 14a & b ); (2) male T3 bearing extremely long notal organ extending to caudal end of A6 ( Fig. 14e & f ); (3) median tooth of gonostylus absent ( Fig. 14j & k ); (4) Male A6–A8 stout, with A7 strongly constricted at base ( Fig. 14f ); (5) in female genital plate, axis broad, extending anteriorly beyond main plate only a short distance; posterior arms slender, elongated for nearly threefourths the total length ( Fig. 15e–g ).

Etymology. The specific name is derived from Latin longus (long) and stipitata (stake), referring to the remarkably elongated notal organ.

Description. Holotype ( Fig. 14a ).

Head ( Fig. 14c ). Vertex yellow, ocellar triangle covered by dark brown marking extending caudally to occiput. Rostrum mottled yellowish brown.

Thorax ( Fig. 14d ). Pronotum dark brown. Mesonotum yellow with dark brown sagittal stripe extending caudally to scutellum; metanotum with similar pattern.

Wings ( Fig. 14a ). Tinged with light brown; R2 bifurcated. Wings only with apical part darkened and brown stripe on pterostigma.

Abdomen. T1–T5 yellowish brown ( Fig. 14a & e ). Male A6 concaved dorso-caudally, A7–A8 dull yellow, stout, A7 greatly constricted at base ( Fig. 14f ). Notal organ slender with dense microsetae along margin, extremely elongated to caudal end of A6; a slender area with dense microsetae extending from T4 to T5 ( Fig. 14e ).

Male genitalia. Yellowish brown. Hypandrium with a basal stalk and a pair of distal hypovalves, basal stalk almost equal to length of hypovalves; hypovalves slender, extending beyond basal lobe of gonostylus, convergent apically, without hypandrial processes ( Fig. 14g & i ); in lateral aspect, hypovalves expanded apically into large subtriangular lobes ( Fig. 14i ). Epandrium truncate apically with subparallel lateral margins ( Fig. 14h ), bearing a pair of slender, subrectangular epandrial lobes at apex ( Fig. 14i ). Gonostylus light brown; median tooth absent; basal lobe blunt, setiferous, strongly concave, with a row of dorsal setae ( Fig. 14j & k ). Ventral valves of aedeagus large, broad-lobed, tapering toward pointed apices; dorsal valves small and stout, concealed in ventral aspect ( Fig. 15a–c ). Paramere with long basal stalk, fused with counterpart as a subrectangular basal frame, bifurcated distally into ventral branch and dorsal branch; ventral branch closely appressed to ventral valve ( Fig. 15a ); dorsal branch slender, arcuate, elongated dorso-laterad ( Fig. 15b ); lateral process broad, curved ventro-mesad, tapering toward apex, with apex projecting apically; dorsal process indistinct, only slightly produced ( Fig. 15a–c ).

Female (Paratype) ( Fig. 14b ). Similar body coloration as in the male. T2–T5 dull yellowish brown with dark brown lateral margins, A7–A8 yellow with brown posterior margin ( Fig. 14b ). Subgenital plate elliptical, yellowish brown, with deep V-shaped emargination ( Fig. 15d ). Genital plate with broad axis extending anteriorly for short distance beyond main plate; posterior arms slender, elongated for three-fourths the total length ( Fig. 15e–g ).

Measurements. Male (n = 2), forewing length 12.90 ± 0.19 mm, width 3.23 ± 0.06 mm; hindwing length 11.81 ± 0.29 mm, width 3.08 ± 0.12 mm. Female (n = 4), forewing length 14.08 ± 0.96 mm, width 3.39 ± 0.10 mm; hindwing length 12.83 ± 0.86 mm, width 3.26 ± 0.10 mm.

Variability. Some females have obscure wing markings; markings of forewings, if present, have apical band absent posteriorly; pterostigmal band is only represented by oblique brown stripe.

Remarks. The extremely elongated notal organ and yellowish brown body coloration allow N. longistipitata sp. n. to be readily differentiated from other species of Neopanorpa .
