Type material

. The type specimens of arrhenotokous D. wani were deposited in the Institute of Plant Protection, Chinese Academy of Agricultural Sciences, Beijing, China.

Arrhenotokous male

(Figs 1A, B). Body length 1.0-1.9 mm, forewing length 0.9-1.2 mm. Body light green with a metallic tint; tegulae dark brown, antenna and mandibles brownish, labial and maxillar palpae pale yellow, compound eyes dark red. Legs with dark green and metallic coxae, brownish and metallic trochanters, anterior 3/4 to the middle of all femora dark brown and metallic, posterior pale yellow, all tibiae dark brown with metallic shine, except base and apical 1/5-2/5 part white or pale yellow, hind tibia with anterior surface dark to white-yellow and posterior surface dark, tarsi yellow, except last 4th tarsomere (dark brown) and 3rd tarsomere (brownish), wings hyaline.

Antenna (Fig. 1C). Antenna with scape 3.8 × as long as broad, pedicel 2.1 × as long as broad, 2 anelli, F1 1.9 × as long as broad, F2 1.7 × as long as broad, clava 3-segmented 3.4 × as long as broad. F1 1.2 × as long as F2, clava 1.7 × as long as scape and 2.6 × as long as F2.

Head (Figs 1C, F). Head wider than height. Toruli inserted a little above the level with the lower margin of eyes. Malar sulcus present, straight, mouth width 1.6 × of malar space.

Thorax (Figs 1C, E). Pronotum, mesonotum and scutellum metallic green. Mesoscutum as long as scutellum. Scutellum 1.09 × as long as broad. Propodeum 2.8 × as broad as long, smooth, without median carina.

Wing (Fig. 1D). Forewings 2.2 × as long as broad. SMV tapering to apex, with six setae dorsally. Costal cell with three rows of setae, ~ 10 dorsal setae on anterior margin apically. Speculum is very small with sparse setations. Relative measurements: SMV: MV: PMV: STV = 10.6: 14.7: 4.7: 4.1.

Metasoma (Figs. 1G and 1H). Petiole short. Gaster 1.8-1.9 × as long as broad. Genitalia: digitus with two developed and two reduced spines.

Arrhenotokous female.

(Fig. 2A). The arrhenotokous female was similar to the thelytokous female in morphological characteristics (Table 2). We only found a little difference on fore- and hind-wings between arrhenotokous and thelytokous D. wani (Figs. 2A, B). For the arrhenotokous and thelytokous females, the forewing with denser setae overall, the costal cell with 2 ~ 4 rows and 2 rows of setae on dorsal surface, respectively and basal cell with 15 ~ 21 hairs and 10 ~ 15 hairs, respectively (Figs 2C-2F, indicated by squares). The setation beneath the marginal vein of the hind-wing of the arrhenotokous female (Fig. 2D) is denser than the same area of the thelytokous female (Fig. 2F).
