Type materials.

Holotype: China • ♂: Guizhou Province, Kuankuoshui National Nature Reserve ; 28°14'N, 107°12'E; sweeping, 28 July 2014; Hai-Yan Sun leg.; IEGU . Paratypes: China • 1 ♂ 3 ♀♀; Guizhou Province, Kuankuoshui National Nature Reserve ; 28°14'N, 107°12'E; sweeping, 28 July 2014; Hai-Yan Sun, Mei-Na Guo leg.; IEGU . 1 ♂ 3 ♀♀; Guizhou Province, Kuankuoshui National Nature Reserve ; 28°14'N, 107°12'E; sweeping, 13 July 2017; Yong-Jin Sui leg.; IEGU .

Diagnosis.

The salient features of the new species include: general color (Figs 2 , 3 ) light yellowish brown; antennae (Figs 6–8 ) with pedicel long, about 4.57 times as long as wide; gonostyli (Figs 11–13 ) symmetrical, inner side with two hooked processes; endosoma (Figs 14–16 ) about 1 / 2 length of periandrium, with an apical curly lamellar process at apex, middle part of ventral with a long spinous process. This species is similar to N. bisaccata Wu & Liang, 2003 , but differs from the latter in: (1) antennae with pedicel long (antennae with pedicel short in N. bisaccata ); (2) gonostyli with two hooked processes at inner side (gonostyli with one hooked process at inner side in N. bisaccata ); and (3) endosoma with an apical curly lamellar process at apex (endosoma without an apical curly lamellar process at apex in N. bisaccata ).

Description.

Measurements. Total length: male 9.7–11.5 mm (N = 3), female 12.3–12.8 mm (N = 6).

Coloration. General color (Figs 2 , 3 ) light yellowish brown. Eyes (Figs 6–8 ) greyish brown to black. Frons and clypeus (Fig. 7 ) yellowish brown to tawny. Pronotum (Figs 2 , 6 ) yellowish brown to brown. Mesonotum (Figs 2 , 6 ) with carinae yellowish white. Outer margins of tegula (Figs 2 , 6 ) yellowish white. Forewings (Fig. 9 ) yellowish white at basal and apical parts, rest yellowish brown to brown, ScP + R red, as shown in Fig. 9 . Hindwings (Fig. 10 ) yellowish brown to brown.

Head and thorax. Head (Figs 2 , 3 , 6–8 ) small, including eyes distinctly narrower than pronotum (1: 1.61). Vertex (Figs 2 , 6 ) trapezoidal, at base 2.58 times wider than length in midline, apex narrower than base (1: 4.44), slightly projecting in front of eyes, anterior margin concave, posterior margin cambered, recessed, lateral carinae slightly developed, median carina absent, disk slightly depressed. Frons (Fig. 7 ) with lateral carinae developed, more divergent near postclypeus, shorter than clypeus (1: 1.6). Clypeus (Fig. 7 ) with basal part angular on both sides, median carina distinct. Postclypeus (Fig. 7 ) with three longitudinal carinae. Rostrum (Figs 7 , 8 ) long, extends beyond the coxa of hind leg, apical segment nearly equal in length and width. Eyes (Figs 6–8 ) with basal part slightly concave in ventral view, ocelli below eyes. Antennae (Figs 6–8 ) with pedicel long, rod-shaped, about 4.57 times as long as wide. Pronotum (Figs 2 , 6 ) with anterior margin angular on both sides, posterior margin concave in inverted V-shaped, shorter than vertex in midline (1: 1.62). Mesonotum (Figs 2 , 6 , 8 ) nearly rhomboid, with median and lateral carinae, longer than 6.5 times pronotum and vertex combined, dorsally elevated, in lateral view raised above vertex distinctly. Forewings (Fig. 9 ) 3.68 times as long as widest point, MP six times branched, MP 1 four times branched with six terminals. Hindwings (Fig. 10 ) with vein ScP + RA short, MP two terminals, CuA two terminals. Spinal formula of hind legs 5 (6) - 7 (8) - 8 (6 ~ 10).

Male terminalia. Pygofer (Figs 11 , 12 ) narrow, in lateral view ventral 1 / 3 nearly quadrangular, dorsal margin sloping, narrowest in the middle; in ventral view oblong. Anal tube (Figs 11 , 17 ) slightly long, in lateral view tapering to ends, basal and apical parts angular, median part of dorsal margin with an angular process; in dorsal view, basal part with an angular process on both sides, lateral margins slightly curved, narrows towards the end, apical margin concave, 1.63 times as long as wide; anal style small, sets at basal 1 / 3. Gonostyli (Figs 11–13 ) symmetrical, basal 1 / 3 slender, then rapidly expand; in lateral view inner and dorsal margins curved, inner side with two hooked processes; in ventral view widest at basal 3 / 5, outer margin with two hooked processes at basal 3 / 5. Aedeagus (Figs 14–16 ) asymmetrical. Periandrium curved, middle part wide relatively. Endosoma more complex, tapering to apex, about 1 / 2 length of periandrium, with an apical curly lamellar process at apex, middle part of ventral with a long spinous process, slightly curved, directed cephalically.

Female terminalia. Terminalia reduced (Figs 30 , 31 ).

Host plant.

Bambusoideae sp. ( Poales : Poaceae : Bambusoideae).

Distribution.

China (Guizhou Province) (Fig. 1 ).

Etymology.

The species name is derived from the Latin word “ lobata ”, referring to endosoma with an apical curly lamellar process at the apex.
