Description. Body length (from apex of vertex to tip of forewings): male 4.7 mm (n = 1), female 4.8–5.1 mm (n = 4)

Coloration. General color black brown ( Figs 30–32 ). Eyes with discal area black and surroundings yellowish brown. Ocelli yellowish brown, semitransparent. Vertex generally yellowish brown, median carina yellow, lateral carinae black brown. Frons yellowish brown to black, discal area with deeper color, both sides with paler color, median carina yellowish brown, lateral carinae blackish brown. Rostrum generally brown, apex dark brown. Pronotum yellowish brown, color becoming deeper from discal area to lateral margin, carinae yellowish white. Mesonotum generally blackish brown, posterior half of area between lateral carinae rustedly yellow, median carina yellowish brown. Forewing blackish brown, semihyaline; veins blackish brown; tubercles black; stigma pale yellowish brown, indistinct; crossveins black; a deep color spot existing basad of fork PCu+A1. Hind tibiae yellowish brown, apical spines black. Abdomen blackish brown with yellow margin.

Head. Vertex ( Figs 14 , 31 ) nearly rectangle, disc hollowed; 1.5 times wider than long; anterior margin slightly concave, posterior margin archedly recessed and middle with a small gap. Frons ( Figs 15 , 32 ) widest slightly below the level of antennae, 1.4 times longer than wide; anterior margin nearly concave into a right angle; lateral carinae S-shaped, median carina disappeared basally. Rostrum reaching hind femur, subapical segment 1.4 times longer than apical segment.

Pronotum and mesonotum. Pronotum ( Figs 14 , 31 ) 1.1 times longer than vertex; median carina distinct; posterior margin concave, forming an obtuse angle. Mesonotum ( Figs 14 , 31 ) 1.6 times longer than pronotum and vertex combined.

Wings. Forewing ( Figs 16 , 30 ) 2.5 times longer than wide, with 6 subapical cells; tubercles generally situated along veins, C and CuP only one side with tubercles, discal area of stigma with tubercles; crossveins not in rows; fork Sc+ RP slightly basad of fork CuA1+CuA2, first veinlet r+m basad of fork MA+MP; RP 2 branches, MA 3 branches, MP 2 branches; fork PCu+A1 basad of center of clavus; fork MA1+MA2 basad fork MP1+MP2.

Legs. Hind tibia with 6 apical spines; chaetotaxy of hind tarsi: 7/8; 2nd hind tarsus with 2 platellae.

Abdomen. Pygofer ( Figs 17, 18 ), dorsal margin concave and loudspeaker-shaped in ventral view, nearly equal width from base to apex; in lateral view, lateral lobes irregularly extended caudally, outer margin waved. Medioventral process ( Fig. 18 ), broad and thick, length equal to width in ventral view, reaching to one third of length of lateral lobes. Anal segment ( Figs 17, 19, 20 ), in lateral view, both dorsal and ventral margins tilted upward; in caudal view, dorsal margin archedly convex, ventral margin waved; 1.5 times longer than wide in dorsal view; loosely connected with pygofer, movable freely. Anal style with base broad and deplanate, apical part fingerlike, not beyond anal segment. Genital styles ( Figs 17, 18, 21 ), in ventral view, outer margin slightly archedly concave, inner margin waved, generally bush-knife-like, touching each other near apex; in lateral view, both dorsal and ventral margins waved; loosely connected with connective, movable freely. Aedeagus ( Figs 23–26 ), base of ventral margin with two folioles whose margin saw-toothed; aedeagus shaft with three spines near apex, two on right side, both spines across ventral margin of aedeagus to the left, the former slender and pointed, directed dorsocephalad, the latter broad and pointless, directed dorsocephalad, another one arising from ventral margin, short and slender, directed dorsocephalad; dorsal margin of aedeagus with a hook-shaped spine at basal one third, apex directed caudad. Flagellum semi-sclerotized, broad and large, structure simple, generally curving right side, forming a moderately long spine on right side of apex, directed ventrocephalad. Connective anchor-shaped, broad and large ( Fig. 22 ); aedeagal shaft 1.3 times as wide as connective plus ventral arm.

Type material. Holotype: 1 3, CHINA: Daheba (28°33´N, 108°30´E) (450–700 m), Yanhe County, Guizhou Province, 5–12 June 2007, P. Zhang; paratypes: 1 Ƥ, same data as holotype; 3 ƤƤ, Lijiaba (700 m), Yanhe County, Guizhou Province, bamboo, 5–12 June 2007, X.-S. Chen.

Host plant. Bamboo.

Distribution. Southwest China (Guizhou Province).

Remarks. This new species is similar to N. okinawana Emeljanov & Hayashi , but differs in: (1) Spine on dorsal margin of aedeagus upright, strongly curving caudad, directed caudad (transverse, slightly curving upward, directed dorsocephalad in okinawana ); (2) Flagellum with one spine near apex (with two spines near apex in okinawana ); (3) The spines near apex of the aedeagus is different in size, direction and position. Etymology. The name is derived from the Latin words “ hamata ”, which refers to spine on dorsal margin of aedeagus upright and hook-like.
