Type material.

Holotype, female [on slide], China, Shandong Province, Qingdao City, Mt. Xiaozhu , 18-20. V .2014, Guo-Hao Zu, Si-Zhu Liu, by yellow pan trapping. Deposited in NEFU .

Paratypes. 2 females: [1 female on slide], same data as holotype; [1 female on slide], China, Hainan Province, Wan Ning City, Shuangxi Village, 17-19.IV.2019, Yu-Ting Jiang , by yellow pan trapping. All deposited in NEFU .

Diagnosis.

Female. Body mainly yellow with green or black markings (Fig. 32 ); F1 4.2 × as long as broad, 1.4-1.5 × as long as pedicel; mid lobe of mesoscutum with three adnotaular setae in one row; propodeum 2.0-2.3 × as long as dorsellum; fore wing with MV 9.5 × as long as STV, speculum closed posteriorly.

Among the species recorded from China, N. flavothorax is similar to N. viridimaculatus (Fullaway) in having similar combination of yellow and green/black parts on mesosoma, but can be separated from N. viridimaculatus by the following characteristics: propodeum completely yellow (vs. completely green); malar sulcus with a subtriangular fovea, extending 0.4-0.5 × the length of malar space (vs. small, 0.2 ×); F1 1.4-1.5 × as long as pedicel (vs. 2.4-2.5 ×). The new species is also similar to the extralimital species N. dispersus Graham in having similar combination of yellow and green/black parts on mesosoma, but can be separated by the following characteristics: propodeum completely yellow (vs. partly green); F1 1.4-1.5 × as long as pedicel (vs. 2.4-2.5 ×).

Description.

Female. Body length 1.9-2.3 mm (1.9 mm). Head with upper half of face and posterior upper part of gena green with metallic reflections, lower half of face yellow; vertex with subtriangular ocelli area and occiput black, mandibles bronze; antenna with radicle, scape and pedicel yellow, flagellum brown. Mesosoma mainly yellow (Fig. 32 ), with pronotum, anterior middle part of mid lobe of mesoscutum black, scutellum green with metallic reflections; legs mainly yellow except tarsomere 4 of all legs dark brown; wings hyaline, venation yellowish brown. Gaster mainly dark brown with basal 1/3 yellow and a yellow spot on the terminal part of gaster, ovipositor sheaths with 1/3 valvula black.

Head (Fig. 11 ) in dorsal view, 2.3 × as broad as long, 1.0-1.1 × as broad as mesosoma. POL 1.2-1.3 × (1.3 ×) OOL, OOL 2.5 × OD. Eyes separated by 1.2 × their length. Malar space ca. 0.6 × as long as eye, malar sulcus with a subtriangular fovea below eyes, extending 0.4-0.5 × (0.4 ×) the length of malar space; mouth opening 1.5 × as wide as malar space. Clypeus with lower margin bidentate. Mandibles tridentate. Facial depression shallow. Torulus with lower margins above the level of ventral margin of eyes. Antenna (Fig. 12 ) with scape 4.5-5.0 × (5.0 ×) as long as broad, slightly shorter than eye length and reaching above the level of vertex; pedicel 2.6 × as long as broad; with four discoid anelli; F1 4.2 × as long as broad, 1.4-1.5 × (1.5 ×) as long as pedicel, F2 and F3 3.2-3.3 × (3.3 ×) and 2.3-2.4 × (2.3 ×) as long as broad respectively; clava 3.8-4.0 × (3.8 ×) as long as broad, 0.8 × as long as F2 and F3 combined, indistinctly segmented and pointed at apex, sensilla numerous, slender; setae on flagellum short and dense.

Mesosoma (Fig. 13 ) 1.9 × as long as broad. Pronotum subconical, 0.3-0.4 × (0.4 ×) as long as mesoscutum. Mid lobe of mesoscutum ca. as broad as long, without median line, with extremely fine reticulation and three adnotaular setae in one row. Scutellum as broad as long; anterior pair of setae situated distinctly before the middle of scutellum, submedian grooves superficial and sublateral grooves distinct, distance between submedian grooves greater than distance between submedian groove and sublateral groove, enclosing a space ca. 2.2 × as long as broad. Reticulation on scutellum similar to that on mesoscutum. Dorsellum ca. 2.5 × as broad as long, without reticulation, posterior edge slightly curved. Propodeum 2.0-2.3 × as long as dorsellum medially, with distinct reticulation, median carina distinct and narrow; spiracles small, circular, separated from anterior margin of propodeum by ca. their own diameter; callus with three setae. Fore wing (Fig. 14 ) 2.8 × as long as broad, SMV with five setae on dorsal surface; costal cell 0.62 × as long as MV; MV 9.5 × as long as STV; STV with a long uncus; speculum small, closed posteriorly. Hind wing 6.2 × as long as broad, pointed. Legs (Fig. 16 ) with metacoxae stout, ca. 1.4 × as long as broad, externo-dorsal surface with fine reticulation, metafemora 3.6 × as long as broad; spur of metatibia 0.7 × as long as length of metabasitarsus.

Gaster (Fig. 15 ) lanceolate, not depressed dorsally, 3.0 × as long as broad and 1.4 × as long as head and mesosoma combined; petiole transverse; the longest cercal seta 2 × as long as the second longest. Ovipositor ca. 0.9 × as long as gaster and slightly exserted at apex of gaster; tip of hypopygium situated at ca. basal 1/3 of gaster.
