( Figs 26–38 ) Measurement. Length of body 2.35–2.60 mm (male), 2.80 mm (female); including forewing 4.15–4.50 mm (male), 5.05 mm (female); forewing length 3.95 mm (male), 4.20 mm (female). Coloration . General color reddish brown. Median line of frons, vertex, pro- and mesonotum, commissural suture white. Areas between carinae of frons somewhat blackish brown. Abdomen somewhat dirty yellow to reddish brown. Pygofer brown. Head and Thorax . Vertex longer submedially than wide at base about 1.1:1, apical margin distinctly emarginate at both sides of median point, lateral carinae concave, submedian carinae not really uniting at apex, basal compartment greatest longer than width at base about 0.9:1. Frons longer in middle line than wide at widest part about 2.5:1, widest at level of ocelli, median carina simple. Post-clypeus wider at base than frons at apex, moderately long, longer than half of frons. Antennae reaching over frontoclypeal suture, basal segment longer than wide, shorter than second about 1:3.5. Post-tibial spur with 23–25 teeth. Tegmina longer than widest part about 3.7:1. Male genitalia . Anal segment of male with lateroapical angles widely separated, each produced in a huge, stout spinose process. Pygofer in profile distinctly wider ventrally than dorsally, at caudal margin strongly produced caudodorsad in a large plate-like process, with 2 small tooth at apex, in caudodorsal view opening longer than width, with a long, spinous process at medioventral, apical margin slightly concave medially. Phallus somewhat compressed, long and tubular, L-shaped and strongly bent ventrad, broad at base, abruptly narrowing to apex, with one slender, long process arising from dorsal margin at basal 1/3, directed ventral. Diaphragm broad, dorsal margin with a node protruding cephalad to supporting phallus, ventral margin with a thumb-like process directed caudad. Genital styles very long, slender, sinuate, divergent apically, quadrate at base, abruptly narrowing at basal 1/3, laterobasal angle with short, spine-like process, distinct at lateral view. Type material . Holotype ♂, CHINA : Yunnan Province, Pianma ( 26°03’N , 98’24’E), Lushui, Nujiang, 17–19 Jun. 2011 , lamping, collected by J.-K. Long. Paratypes : 1♂ , 3♀♀, same data as holotype . Host plant . Unknown. Distribution . South China (Yunnan). Remarks . This new species is similar to N. bispinatus sp. nov. , but can be distinguished from the latter by the following features: anal segment each produced in a shorter and slender process; pygofer at plate-like process of caudal margin with 2 small teeth-like processes at apex, with a spine-like medioventral process; phallus with one slender and longer process at basal 1/3; genital styles basal angle with shorter process. The structural features of male genitalia of this species are distinctly different from other known species in this genus. Etymology . The specific name refers to the pygofer with a long, spinous process at medioventral margin.
