Head green with metallic tinge, vertex without a yellow area surrounding ocelli; eyes red; ocelli dark red; antennae with scape, pedicel and flagellum yellow; mandibles dark brown. Mesosoma green with strong metallic tinge. Legs and coxae yellow or pale yellow except metacoxa with green metallic luster as on mesosoma and apical tarsomeres infuscate. Color patterns on metasomal tergites symmetric: anterior part of tergite I with green tinge; tergites I–III yellow, median and anterior parts of tergite IV yellow, laterally with pale green metallic tinge; tergites V–VII with green metallic tinge. Ovipositor sheaths dark with metallic reflections, apex of hypopygium with green metallic tinge.

Head ( Fig. 22 ) with ocellar triangle, not surrounded by distinct grooves. POL 3.5× OOL. Malar space 0.42× as long as height of eye. Scrobal area with a distinct longitudinal median carina. Antennae inserted at level of lower margin of eyes. Malar sulcus strongly curved. Head 1.2× as wide as high, 1.5× as wide as midlobe of mesoscutum.

Antenna ( Fig. 23 ) with scape 4× as long as wide, not reaching median ocellus; pedicel 1.4×, F1 1.7×, F2 1.4×, F3 1.25×, and clava 2.3× as long as wide; clava with sutures between clavomeres difficult to see; C3 short with rounded apex, without a terminal spine.

Mesosoma ( Fig. 24 ) 1.6× as long as wide. Pronotum medially very short in dorsal view. Midlobe of mesoscutum as long as wide, with median line very weak, and with a single row of 3 adnotaular setae. Scutellum 0.8× as long as broad, with anterior pair of setae in its posterior half, submedian and sublateral grooves distinct and parallel to each other. Propodeum medially as long as dorsellum, with a median carina but without paraspiracular carina; callus with 4 or 5 setae; with a groove extending from spiracle to posterior margin of propodeum.

Fore wing ( Fig. 25 ) hyaline, 1.9× as long as wide; CC 2× as long as MV; MV thick, 4× as long as wide; MV 1.7× as long as STV, with 6 marginal setae (about 0.3× as long as STV); STV rather thick; PSV not thicker than MV, very short, stub-like, less than 0.5× length of STV. Speculum large, extending from parastigma to stigmal vein. Discal setae short. Hind wing rounded apically, 5.5× as long as wide.

Legs. Metafemur 4.8× as long as wide.

Metasoma as long as mesosoma, 1.8× as long as wide; hypopygium extending to about 0.5× length of metasoma; cercal setae subequal in length; ovipositor sheaths slightly protruding.

Variation. Body length 1.1–1.3mm. Metallic patterns on metasomal tergites vary from small to large. HW 1.2– 1.3× HL. POL 3–3.5× OOL. EL 1.8–2.4× MS. ML 1.5–1.6× MW. STL 0.8–0.9× STW. FWL 1.8–1.9× FWW. HWL 4.8–5.5× HWW. CC 1.8–2× MV. MV 1.7–2.5× STV. GL 1.7–1.8× GW. MFL 3–4.8× MFW.

MALE ( Figs 26–30 ). Body length 1.01.3mm. Similar to female except as follows: funicle 4-segmented; scape with pale to light brown, ventral plaque apically, 0.33× length of scape; metasoma with area of yellow smaller than for female; STV partly infuscate. HW 1.2–1.25× HL. POL 3.7–4.3× OOL. EL 1.8–2.1× MS. ML 1.6–1.7× MW. STL 0.9–1.1× STW. FWL 1.7–1.8× FWW. HWL 4.8–5.1× HWW. CC 1.8–1.9× MV. MV 1.7–2.1× STV. GL 1.75– 1.9× GW. MFL 3.0–3.4× MFW. VP 0.4–0.43× SL.

Etymology. The species is named after the habitat type (Gobi Desert) of the new species.

Hosts. Unknown.

Diagnosis. This species is similar to D. kasparyani . It differs in POL being at least 3× OOL, the hind wing 4.8– 5.5× as long as broad, metasomal tergite III yellow, and metasomal tergite IV yellow medially and anteriorly but laterally with pale green metallic tinges. In D. kasparyani the POL is 1.45–1.6× OOL, the hind wing 8.0–9.5× as long as broad, and metasomal tergites III–IV are completely metallic with a strong metallic tinge.
