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 .
