Diagnosis

The new species can be recognized by the following features: 1) bearing special wing markings, with apical and pterostigmal bands connected along anterior margin, and an elongated oblique marginal spot ( Fig. 3 A–B); in males, 2) notal organ well-developed, slender, stick-like and extending slightly beyond the middle of A6 ( Fig. 3D ); 3) hypovalves distinctly curled ventrad ( Fig. 3 H–I); and 4) hypandrial processes curved and finger-like ( Fig. 3F, I ).

Etymology

The specific epithet is dedicated to the collector of the type specimens, Xing-Min Wang.

Description

Male

MEASUREMENTS. Holotype: FL = 11.4 mm, FW = 2.3 mm; HL = 10.5 mm, HW = 2.2 mm. Other specimens: FL = 11.3–11.5 mm, FW = 2.3–2.4 mm; HL = 10.3–10.4 mm, HW = 2.2–2.3 mm.

HEAD ( Fig. 3C ). Vertex dark brown. Frons and hind margin of antennal sockets light yellowish brown. Rostrum sordidly yellowish brown with two faint dark stripes along clypeus. Maxillary and labial palps mostly yellowish brown with terminal segment dark brown. Scape light yellowish brown, pedicel dark brown; flagellomeres 43, black.

THORAX ( Fig. 3A ). Pronotum dark brown, with 10 black stout setae on anterior margin. Mesonotum black anteriorly and mesally, with two large light yellowish brown spots near wing bases; metanotum similar to mesonotum but with larger light yellowish brown spot laterally; scutella brown. Pleura light yellowish brown. Legs light yellowish brown, slender.

WINGS ( Fig. 3A ). Wing membrane faintly tinged with yellow, hyaline; markings brown; pterostigma light brown; veins brown, except whitish crossveins in apical half. Forewing with broad apical and pterostigmal bands; apical band greatly projected at inner margin, and connected to pterostigmal band along costal margin; pterostigmal band complete, with basal branch approximately two times as broad as apical branch; elongated marginal spot oblique, almost connected to basal branch of pterostigmal band posteriorly, forming N-shaped pattern; basal band split into two irregular spots; R 2a simple. Hindwing similar to forewings in shape and venation, but lacking marginal spot; basal band represented by indistinct spot between CuA and CuP.

ABDOMEN ( Fig. 3A, D ). A1–A5 sordidly dark yellowish brown, A7–A9 yellowish brown. Notal organ on posterior margin of T3 well-developed, slender, stick-like and extending slightly beyond middle portion of A6, distinctly curved dorsad in apical half, and bearing numerous short setae on ventral surface. T4 with membranous area before barely raised postnotal organ. A6 approximately two times as long as A5, cylindrical. A7 slightly shorter than A6, slightly enlarged toward truncated apex; A8 shorter than A7 with beveled apex.

GENITALIA ( Fig. 3 E–L). Genital bulb bold and oval, widest near apex of gonocoxites. Epandrium narrow, truncated at apex; epandrial lobes boot-shaped with tapering apex, and greatly convergent. Hypandrium with broad basal stalk and split into a pair of hypovalves apically; hypandrial processes slender, fingerlike, slightly curved laterad apically; hypovalves mostly whitish but black at base, hirsute and greatly curled ventrad. Gonostylus concaved near basal one-third on outer margin; median tooth barely raised; basal process large and setose. Parameres flat, distinctly projected ventrad, with slightly sclerotized dorsal bridge connected to base of lateral processes. Ventral aedeagal valves with acute and translucent apexes; dorsal valves blunt and shorter than ventral valves; dorsal processes broad and translucent; lateral processes broad and rounded apically.

Female

Similar to males in body colors but with denser wing markings ( Fig. 3B ). In forewings, apical band extending to ending of M 3 posteriorly; marginal spot dense and distinctly connected to basal branch of pterostigmal band; a small irregular spot on Sc between marginal spot and pterostigmal band.

MEASUREMENTS. FL = 12.4 mm, FW = 2.4 mm; HL = 11.3 mm, HW = 2.3 mm.

GENITALIA ( Fig. 3 M–N). Subgenital plate long and suboval, with shallow V-shaped emargination apically. Medigynium with axis slightly shorter than half of total length, parallel apodemes densely sclerotized; posterior arms slightly longer than axis, distinctly twisted medially and slightly spatulate in apical half.

Distribution

China: western Yunnan.

Comments

Although N. xingmini sp. nov. resembles N. luojishana sp. nov. in the well-developed male notal organ, it lacks the modified postnotal organs on A5 and A6 ( Fig. 3D ). It is similar to the Tibetan species N. tibetensis Hua & Chou, 1999 superficially, but can be distinguished from the latter by the smaller size with a maximum male FL of 11.5 mm (cf. exceeding 14.5 mm), the innerly projected apical band (cf. simple), and the details of the male and female genitalia. The female medigynium of N. xingmini sp. nov. resembles that of N. triangulata Wang & Hua, 2018 from Yunnan, N. liquifasciata Byers, 1999 and N. similis Byers, 1999 from Kachin, northern Myanmar, but the unique wing markings and welldeveloped male notal organ make the new species distinctive.
