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.

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.
