Neopanorpa wuchaoi sp. nov.

( Figs 11–24 )

Type material. Hඈඅඈඍඒඉൾ: 3, CHINA: T ංൻൾඍ: Shannan Prefecture, Cona County, 27°48′41″N, 91°45′06″E, 2438 m, 16.vii.2019, leg. Chao Wu ( DALU). Pൺඋൺඍඒඉൾඌ:13 2 ♀♀, same data as the holotype ( DALU).

Diagnosis. The new species resembles Neopanorpa ramulata Byers, 1975 , but can be differentiated from the latter by the following characters: 1) antennae longer than forewings (versus shorter); 2) wings with greatly reduced markings (vs. well developed); in males, 3) notal organ on T3 extending near the posterior border of T4 (vs. extending to middle of T4); 4) epandrium greatly emarginated terminally (vs. simple); 5) basal lobe of gonostylus bifurcated basally (vs. simple); 6) paramere bifurcated subbasally (vs. subapically); 7) dorsal processes of aedeagus broadly leaf-shaped and divergent distally (vs. blade-shaped and convergent distally); and in females, 8) axis completely concealed in main plate basally (vs. extending beyond main plate basally).

Description. Measurements (mm). Male (holotype). AtL 14.0, AbL FL 8.8, BL 12.4, FL 12.6, FW 2.7, HL 11.6, HW 2.5. Female (paratypes). AtL 14.0, AbL 7.4, BL 11.8, FL 13.0, FW 2.8, HL 12.0, HW 2.7.

Male. Head ( Figs 11, 13 ). Vertex and occiput mostly black, large yellowish brown spot on each side of occiput. Rostrum slender, yellowish brown with pair of brown longitudinal stripes. Scape yellowish brown, pedicel dark brown, flagellum black with 47–49 flagellomeres.

Thorax ( Fig. 11 ). Pronotum dark brown and lacking stout setae along anterior margin. Meso- and metanotum mostly yellowish brown with narrow black median stripe. Legs and pleura yellow with apex of tibia and distal tarsomeres blackish.

Wings ( Fig. 11 ). Narrow basally with rounded apex. Membrane hyaline and strongly tinged with yellow; markings entirely reduced; pterostigma brown; veins mostly brown with distal cross-veins whitish. Forewing Sc extending to pterostigmal area; R 1 simple; Rs six-branched with R 2 trifurcated, R 2a bifurcated; M 4 greatly bent at m-cu; 1A ending far before origin of Rs (ORs); one cross-vein between 1A and 2A. Hindwings similar to forewings with more reduced markings.

Abdomen ( Figs 11, 15, 16 ). T1–T5 yellowish brown with lateral margin blackish, S1–S5 light yellowish brown. Notal organ on T3 extending approximately to 4/5 of T4, finger-like and clavate terminally; postnotal organ on T4 rounded. A6 yellowish brown, cylindrical. A7 yellowish brown, greatly constricted basally and gradually enlarged towards truncated apex; A8 similar to A7 but shorter and beveled at apex.

Male genitalia ( Figs 17–21 ). Genital bulb yellowish brown, long elliptical. Epandrium broad and tapering towards apex, with deep O-shaped emargination and forming pair of finger-like processes laterally, epandrial lobes small. Hypandrium with greatly shortened basal stalk, split into pair of hypovalves and lacking hypandrial processes. Hypovalves approximately three times as long as basal stalk of hypandrium, parallel, and bifurcated into pair of finger-like processes terminally, with inner branch short, outer branch longer and greatly curled inward. Gonocoxites slightly beveled apically. Gonostyli slightly shorter than gonocoxites, with basal process and median tooth greatly elongated; median tooth shortly bifurcated terminally into two pointed apices. Parameres bifurcated subbasally; basal stalk fused basally; ventral branch approximately 4/5 times as long as dorsal branch, enlarg- ed subbasally and greatly tapering into pointed apex; dorsal branch similar in shape but slightly sinuate, with distal 1/3 stretching into groove between basal lobe and median tooth of gonostyli; both branches covered with numerous microtrichia along distal half of outer margin. Ventral aedeagal valves pale with subacute apex; dorsal aedeagal valves greatly elongated with acute apex, and slightly convergent; dorsal processes greatly elongated and broad, with subtriangular, acute process in middle of inner margin, and 10–12 long stout setae on distal half of inner margin; lateral processes elongated posteriorly; dorsal bridge slender and connected to base of lateral processes.

Female. Similar to males in general appearance but with greatly reduced, spot-like pterostigmal band in pterostigmal area ( Fig. 12 ). Female genitalia ( Figs 22–24 ). Subgenital plate broadly oval, with V-shaped terminal emargination and long stout setae on distal portion. Medigynium with main plate greatly developed, subtrapezoidal and constricted in distal 1/3; posterior arms approximately half as long as main plate, greatly twisted subbasally, and subacute apically; axis completely concealed in main plate with apodemes closely aligned.

Etymology. The specific epithet is dedicated to my friend Mr. Chao Wu for collecting the type specimens.

Distribution. Indo-Malayan Realm: China: Tibet (Cona) ( Fig. 1 ).
