Antenna filiform; antennal segments of specimen from China, Pingyin City, in following proportions: 6:5:8:7:7:7:7:6:6:9; antennal segment 3 less than three times as long as broad: 8:3. Head dull, granulated; frontal line absent; occipital carina absent; ocelli very large; holotype of N. hishimonovorus with POL = 3; OL = 1; OOL = 0.4; in male specimen from China, Pingyin City, POL = 6; OL = 2; OOL = 1; greatest breadth of posterior ocelli shorter than POL (4:6); vertex without two oval smooth and shiny areas situated on sides of posterior ocelli and occupying areas between posterior ocelli and eyes. Palpal formula 6/3. Scutum shiny or dull, granulated. Notauli complete, posteriorly separated; minimum distance between notauli less long than greatest breadth of posterior ocelli (3:4).

Jianfengling), 13.V.1983, Z. Bouček leg., 1♀ (BMNH); Zhejiang, Mt. Gutianshan, 18.VIII.2003, Jingxian Liu & Wuqing Fan leg., 1♀ (ZJUC). MALAYSIA: Sabah, Kinabalu National Park, Headquarters area, 1560 m, 9.IX.1983 (USNM). Palaearctic: CHINA: Shandong, Shanghe, 26.IX.2003, Jiahe Yan leg., reared from Drabescus ogumae Matsumura, 1♀ (ZJUC); same locality label, 16.X.2003, reared from Hishimonus sellatus (Uhler), 1♀ and 1♂ (ZJUC); same locality label, 29.V.2004, collected by sweeping, 1♀ (ZJUC); same locality label, VII.2004, reared from Cicadellid, 1♀ (ZJUC); Shandong, Pingyin City, 8.VII.2006, reared from Cicadellid on rose, Shimin Ding leg., 5♀♀ and 3♂ (ZJUC); same locality label, 5–8.VII.2005, Jiahe Yan leg., 2♀♀ and 2♂ (ZJUC).
Hosts. Cicadellidae (Guglielmino & Olmi, 2006): in China (Shandong): Drabescus ogumae Matsumura and Hishimonus sellatus (Uhler).
Natural enemies. In China, Shandong, Shanghe, this species can be parasitized by an unidentified species of Encyrtidae.
Distribution. China (Jiangsu, Guangdong, Hainan, Zhejiang, Shandong), India (Karnataka), Malaysia (Sabah).
Remarks. N. hishimonovorus is here synonymyzed with G. rufoniger after study of a series of females and males reared from a leafhopper feeding on rose in China, Shandong, Pingyin City (see distribution above). The males and the females were compared respectively with the ♂ holotype of N. hishimonovorus and the ♀ holotype of G. rufoniger, proving the synonymy.
