Type material.

Holotype: ♂, China: Yunnan, Xichou County, Fadou (23°38'N, 104°78'E), 28 June 2013, Ying-Jian Wang; paratypes: 11♂♂, 29♀♀, same data as holotype, Ying-Jian Wang and Qiang Luo.

Description.

Body length: male 5.8-6.3 mm (N = 7), female 6.3-6.6 mm (N = 20); forewing length: male 5.0-5.3 mm (N = 7), female 5.1-5.8 mm (N = 20).

Coloration. General color yellowish brown (Figs 43-48) (brown in female). Eyes brown, ocelli yellow. Vertex generally yellowish brown, carinae brown to dark brown (except median carina milky). Face generally yellow, carinae brown to dark brown; rostrum yellowish brown with dark brownish apex. Pronotum and mesonotum with areas between lateral carinae yellow, lateral areas brown. Forewing semihyaline, alternately yellowish brown and pale yellowish brown, with black spots on end of longitudinal veins. Hind tibiae yellowish brown. Ventral abdomen yellowish brown.

Head and thorax. Vertex (Figs 43, 45, 47) broad, 2.0 times wider than long; anterior margin slightly projected, posterior margin convexly recessed. Frons same as N. acutata . Pronotum (Figs 43, 45, 47) 2.1 times longer than vertex; median carina indistinct, posterior margin rather right-angled. Mesonotum 1.7 times longer than pronotum and vertex combined. Forewing (Figs 44, 46, 49) amply exceeding tip of abdomen, 2.4 times longer than wide, other veins same as N. acutata . Hind tibia with 6 apical spines; chaetotaxy of hind tarsi: 5/7.

Male genitalia. Pygofer (Figs 50, 51), same as N. acutata . Anal segment (Figs 50, 52), in lateral view, dorsal margin nearly straight, ventral margin slightly convex, with a horn-like process extending to apex ventrally; in dorsal view 1.8 times longer than wide; anal style strap-like, beyond anal segment. Apical margin of genital styles (Figs 50, 53) with a small blunt process, dorsal margin bending inwards in the middle. Aedeagus (Figs 54-57) with five spinose processes. Right side of periandrium with a very long process near apex directed ventrocephally. Left side of periandrium with a short reversed process at base directed dorsocaudally, and a medium sized process near apex directed dorsocephally. Flagellum moderately sclerotised. Right side with a long process near base directed ventrocephallly. Apex near dorsal margin with a short process, curved towards cephalad.

Female genitalia. Pygofer (Figs 58-59, 61) same as in N. acutata . Anal tube (Figs 58, 60) short, 1.2 times longer than wide in dorsal view, ventral margin slightly concave in lateral view; anal styles relatively short and small, finger-shaped. Gonapophysis VIII (Fig. 62) slightly concave basally. Gonapophysis IX and gonoplac (Figs 63-64) same as in N. acutata , while length of gonoplac 4.3 times of its width, and width of spiculated area approximately 1/5 of gonoplac. Posterior vagina (Figs 65-66) elongate, right side with a long longitudinal sclerite in ventral view and a shorter one in dorsal view, forming a cylindrical structure, left side with a moderately long sclerite in ventral view, hat-shaped. In dorsal view, middle area of posterior vagina with a drop-like sclerite, right side with two small oblong sclerites near terminal.

Distribution.

China (Yunnan).

Etymology.

The specific name is derived from the Latin word " reversa ", referring to the left side of the periandrium with a short reversed process basally.

Remarks.

Male genitalia of N. reversa sp. n. is similar to N. maai Tsaur & Hsu, 2003, but differs in: (1) left side of periandrium with a short reversed process basally ( N. maai without process in same position); (2) two processes on both lateral sides of periandrium near apex (three processes on periandrium near apex, two on ventral margin and one on right side in N. maai ); (3) flagellum with smooth apical margin (sinuate in N. maai ).

Female genitalia of N. reversa is similar to N. bidentata Zhang & Chen, 2013, but differs in: posterior vagina with a long longitudinal sclerite on left side (posterior vagina with a long longitudinal sclerite on right side in N. bidentata ).
