Diagnosis

The new species can be recognized by the following features: 1) vertex yellowish brown with a broad black stripe enclosing ocellar triangle and extending to occiput ( Fig. 2C View Fig ); 2) wings nearly lacking markings except distinctly reduced apical and pterostigmal bands ( Figs 1 View Fig , 2 View Fig A–B); in males, 3) notal organ well-developed, slender stick-like and extending slightly beyond posterior border of T5 ( Figs 1 View Fig , 2A, D View Fig ); 4) three postnotal organs on T4–T6, respectively ( Fig. 2D View Fig ); 5) genital bulb distinctly elongated, over two times as long as wide ( Fig. 2 View Fig E–F); 6) gonostylus bearing a tuft of long stout setae on middle of ventral surface ( Fig. 2 View Fig F–G); and in females, 7) medigynium with long axis nearly two-thirds of total length, and greatly divergent apodemes ( Fig. 2L View Fig ).

Etymology

The new species is named after the type locality, Luojishan (= Mt. Luoji).

Description

Male

MEASUREMENTS. Holotype: FL = 13.6 mm, FW = 2.9 mm; HL = 12.4 mm, HW = 2.8 mm. Other specimens: FL = 13.2–13.6 mm, FW = 2.8–2.9 mm; HL = 12.2–12.5 mm, HW = 2.7–2.8 mm.

HEAD ( Fig. 2C View Fig ). Vertex yellowish brown laterally, with broad black stripe enclosing ocellar triangle and extending to occiput. Frons dark yellowish brown. Rostrum sordidly yellowish brown with two faint dark stripes along clypeus; labrum dark yellowish brown. Maxillary and labial palps yellowish brown basally and gradually darkening toward apical segment. Scape yellowish brown, pedicel dark yellowish brown; flagellomeres 40, yellowish brown in several basal segments and gradually darkening toward apex. THORAX ( Fig. 2A View Fig ). Pronotum dark yellowish brown, with 6–10 stout setae along anterior margin. Mesonotum dark brown anteriorly and mesally, and bearing two large light yellowish brown spots near wing bases; metanotum similar to mesonotum but with larger light yellowish brown spots laterally; scutella dark brown. Pleura and legs light yellowish brown.

WINGS ( Fig. 2A View Fig ). Wing membrane slightly tinged with yellowish brown, hyaline with greatly reduced markings; pterostigma brown and distinct; veins dark brown except whitish crossveins in apical half. Forewing with greatly reduced apical band between R 2b and R 5; pterostigmal band only flattened semicircular stripe on pterostigma; other markings absent; in some individuals small faint spot at ending of CuA; R 2a shortly bifurcated. Hindwing similar to forewings in shape and venation, with much more reduced apical band.

ABDOMEN ( Fig. 2A, D View Fig ). T2 dark brown; T3 mostly dark brown and yellowish brown on posterior margin; T4 and T5 dark brown anteriorly and yellowish brown posteriorly. Notal organ on hind margin of T3 slender, with apex slightly beyond posterior margin of T5, and bearing dense short setae on ventral surface. Postnotal organs represented by three discontinuous, hirsute ridges on T4–T6, respectively. A6 yellowish brown, slightly longer than A5 and tapering toward apex, and emarginate in U-shape at apex dorsally. A7 slightly shorter than A6, distinctly constricted at one-fifth of base and slightly beveled apically. A8 shorter than A7, distinctly constricted at base, humped ventrally, and beveled apically.

GENITALIA ( Fig. 2 View Fig E–J). Genital bulb long ellipsoidal, over two times as long as wide. Epandrium narrow, slightly emarginate at apex; epandrial lobes truncate with hook-shaped caudal corner. Hypandrium with broad basal stalk and split into paired hypovalves at middle; hypovalve long fusiform and hirsute, with slender apex; hypandrial processes triangular. Gonocoxite bearing several long and stout setae on inner side of apex ventrally. Gonostylus shorter than gonocoxite, slightly concave at outer margin near base, greatly curved dorsad in apical half, and bearing a tuft of black, long and stout setae at middle of ventral surface; median tooth on inner margin barely raised; basal process large, distinctly concaved. Parameres slender, convergent apically, with basal stalks fused into sclerotized frame; dorsal bridge greatly sclerotized, curved and connected to base of lateral processes. Ventral aedeagal valves conical; dorsal valves short and blunt; dorsal processes broad with a longitudinal ridge; lateral processes distinctly bending caudally, with acute apex almost at same level of ventral valves.

Female

Similar to males in body coloration except denser wing markings ( Fig. 2B View Fig ). In forewing, apical band broad between R 2a and R 5; three additional small stripes between R 5 and M 3; pterostigmal band shattered into several parts: large semicircular spot on pterostigma, small rounded spot enclosing nygma anterior to M 1, large irregular spot near ending of CuA, and two small spots near ending of M 4. Two small spots each enclosing nygma anterior to thyridium, and near ending of CuP, respectively. Hindwing similar to forewings in shape and venation but with much more reduced markings.

MEASUREMENTS. FL = 13.6–13.7 mm, FW = 2.8–2.9 mm; HL = 12.3–12.5 mm, HW = 2.7–2.8 mm.

GENITALIA ( Fig. 2 View Fig K–L). Subgenital plate oval, with V-shaped emargination at apex. Medigynium with long axis approximately two-thirds as long as total length, apodemes greatly divergent at base; posterior arms slender, approximately one-third as long as medigynium, twisted subbasally, and slightly spatulate apically.

Distribution

China: southern Sichuan.

Comments

Neopanorpa luojishana sp. nov. bears three postnotal organs on T4–T6 ( Fig. 2D View Fig ), respectively, greatly resembling N. dorsalis Byers, 1965 from Dalat, southern Vietnam, N. longistipitata Wang & Hua, 2018 from Dali, northwestern Yunnan, and N. setigera Wang & Hua, 2018 from Shimian, western Sichuan, China. By contrast, most other Neopanorpa species only bear a single postnotal organ on T4.
