Epandrium as long as wide, basally with 2 large lateral processes; surstylus with wide dorsal lobe bearing shallow concave apex, ventral lobe slender and curved, with 3 apical bristles. Cercus white, somewhat rectangular, bearing white hairs. Aedeagus black, slender. Female. Body length 3.2 mm, wing length 3.5 mm. Similar to male. Type Material. Holotype: male, Hainan: Jianfengling, Tianchi, 2007.VI.5, Jinxian Liu. Paratype: 1 female, same data as holotype. Holotype and paratype deposited in CAU. Etymology. The specific epithet derives from the type locality in Hainan. Distribution. Known only from the type locality in Hainan. Remarks. The new species is similar to Neurigona yunnana Wang, Yang et Grootaert from Yunnan, but can be separated from the latter by having 10–11 irregularly paired acr and tarsomere I 5 dark brown. In N. yunnana, 17–18 irregularly paired acr bristles are present and tarsomere I 5 is white.

Viridigona zhangae (Wang, Yang & Grootaert, 2006), comb. nov. Neurigona zhangae Wang, Yang & Grootaert, 2006: 87. Type-locality: Beijing. Diagnosis. Thorax dark metallic green with pale grey pollen, pleuron shiny black, mesonotum dark metallic green with pale lateral margin. Fore tarsomere 4 with ventral surface of basal half somewhat swollen, with dense pale setae; tarsomere 5 with long claws chiefly black with yellow base. Male cercus elongated, with special setae and process. Material examined. 3 ♂ and 2 ♀, Beijing, Mentougou, Baihuashan, 2005.VII.15, Junhua Zhang (CAU); 1 ♂, Beijing: Mentougou, Baihuashan, 2005.VII.16, Hui Dong & Kuiyan Zhang (CAU). Remarks. The species is somewhat similar to species of Neurigona, but can be separated from the latter by the metallic green mesonotum and elongated male cercus. In species of Neurigona, the mesonotum is mainly yellow, at most with metallic green spots, and the male cercus is short and round (Naglis 2002). Viridigona zhangae represents a new Palearctic record for the genus. Viridigona Naglis is now distributed in the Neotropical, Nearctic and Palaearctic regions with 29 known species. Only one species of this genus is currently known from China.

Known only from the type locality in Neimenggu. Remarks. The species is similar to Neurigona micropyga Negrobov, but can be separated from the latter by the chiefly black pleuron and the normal fore claw. In N. micropyga, the pleuron is chiefly yellow, and the fore claw is distinctly elongated, spine-like., Published as part of Wang, Mengqing, Chen, Hongyin & Yang, Ding, 2010, New species of the genus Neurigona (Diptera: Dolichopodidae) from China, pp. 53-61 in Zootaxa 2517 (1) on page 58, DOI: 10.11646/zootaxa.2517.1.6, http://zenodo.org/record/5302128
