Holotype, female [on slide], China, Hainan Province, Haikou City, Hainan University , 27-29. VI .2019, Yu-Ting Jiang, by yellow pan trapping. Deposited in NEFU .

Paratypes. 6 females, 4 males: [2 females and 2 males on slides, 1 male on card], China, Hainan Province, Haikou City, same data as holotype; [2 females on slides, 1 male and 2 females on cards], China, Shandong Province, Qingdao City, Mt. Xiaozhu , 18-20. V .2014, Guo-Hao Zu, Si-Zhu Liu, by yellow pan trapping. All deposited in NEFU .

Diagnosis.

Female. Body metallic green with lower half of face yellow and basal 1/3 of gaster yellowish; antenna with three discoid anelli, F1 1.4-1.5 × as long as pedicel; midlobe of mesoscutum with two rows of adnotaular setae; fore wing 2.7-2.8 × as long as broad, speculum closed posteriorly; SMV with five setae on dorsal surface. Male. Antenna with scape shorter than an eye, reaching above vertex, 4 × as long as broad; ventral plaque 0.63 × as long as scape.

Among the species recorded from China, N. basiflavus is similar to N. mediterraneus in F1 1.4-1.6 × as long as pedicel, but can be separated from it by the following combination of characteristics: lower half of face yellow and basal 1/3 of gaster yellowish (vs. green); antennal clava 3.5-3.7 × as long as broad (vs. 2.8-3.3 ×); fore wing with speculum closed posteriorly (vs. open posteriorly). The new species is also similar to the extralimital species N. beonus Narendran in base of gaster yellow, but can be separated from it by following characteristics: pronotum 0.3-0.5 × as long as mesoscutum (vs. 0.93 ×); fore wing 2.7-2.8 × as long as broad (vs. 3.7 ×), SMV with five setae on dorsal surface (vs. six), speculum closed posteriorly (vs. open posteriorly).
