( Figs 1–12 ) Measurement. Length of body 2.90–3.00 mm (male), 3.60 mm (female); including forewing 4.85–5.00 mm (male), 5.95 mm (female); forewing length 4.50 mm (male), 5.40 mm (female). Coloration . General color yellowish brown. Median line of frons, vertex, pro- and mesonotum, commissural suture white. Areas between carinae of frons somewhat black. Abdomen somewhat yellowish white. Pygofer yellowish. Head and Thorax . Vertex wider submedially than long at base about 1.2:1, apical margin transverse, lateral carinae nearly straight, submedian carinae not really uniting at apex, basal compartment wider at base than greatest length about 1.1:1. Frons longer in middle line than wide at widest part about 2.8:1, widest at middle, median carina simple. Post-clypeus wider at base than frons at apex, very long, longer than half of frons. Antennae reaching frontoclypeal suture, basal segment longer than wide, shorter than second about 1:2.4. Post-tibial spur with 22–25 teeth. Tegmina longer than widest part about 3.2:1. FIGURES 1–12. Neunkanodes bispinatus s p. nov. (1) Head and thorax, dorsal view; (2) Frons and clypeus; (3) Forewing; (4) Male genitalia, posterior view; (5) Same, left side view; (6) Pygofer, left side view; (7) Same, posterior view; (8) Anal segment, aedeagus and genital style, left lateral view; (9) Anal segment, posterior view; (10) Anal segment, left side view; (11) Aedeagus, left side view; (12) Genital style, left side view. Scale bars = 0.5 mm (Figs 1–3), 0.2 mm (Figs 4–7), 0.1 mm (Figs 8–12). Male Genitalia . Anal segment of male with lateroapical angles widely separated, each produced in a long, stout process, gradually narrowing near middle, obtuse at apex. Pygofer in profile slightly wider ventrally than dorsally, at caudal margin strongly produced caudodorsad in a large plate-like process, with 2 spine-like processes at apex margin, in posterior view opening longer than wide, ventral margin planus, without medioventral process. Phallus somewhat compressed, long and tubular, C-shaped and strongly bent ventrad, broad at base, abruptly narrowing to apex, with one shorter, spinous process at middle directed caudad. 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 long, 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 : 3♀♀, same data as holotype . Host plant . Unknown. Distribution . South China (Yunnan). Remarks . This new species is similar to N. unispinatus sp. nov. , but can be distinguished from the latter by the following features: anal segment each produced in a longer and stouter process; pygofer produced in a plate-like process, with 2 long spine-like processes at apex, without medioventral process; phallus with one shorter process at middle; genital styles at basal angle with slender process. The structural features of male genitalia are distinctly different from other known species of the genus. Etymology . The specific name refers to the lobe of pygofer at caudal margin with two spine-like processes.
