( Figs 34 View FIGURE 34 , 68 View FIGURE 68. 36–60 )
Description. Holotype. Female. Body length 2.0 mm, fore wing length 2.4 mm.
Head. Transverse in dorsal view, 2.0× as wide as long, 0.9× as wide as mesoscutum ( Fig. 34d View FIGURE 34 ). Temple shiny with relatively strong punctures, weakly constricted behind eyes from dorsal view. Face ( Fig. 34i View FIGURE 34 ) transverse, 0.8× as high as wide, shiny with distinct punctures, inner margins of eyes subparallel. Ocelli large, posterior tangent to anterior ocellus weakly transecting posterior pair of ocelli, distance between fore and a hind ocellus shorter than diameter of an hind ocellus, POL:OD:OOL = 2.5:2.5:3.5. Antenna shorter than body length, penultimate antennomere cubic.
Mesosoma. Length:width:height = 41.0:26.0:26.5. Disc of mesonotum ( Fig. 34f View FIGURE 34 ) shiny, with strong, dense punctures. Scutellar sulcus straight, broad with carinae inbetween. Scutellum shiny with sharp, sparse punctures laterally. Propodeum shiny, with well-defined areolation which nearly closed transversely at anterior end and rugose-punctate anteriorly, three posterior fields highly shiny and polished, anterio-lateral parts shiny with indistinct punctures. Mesopleuron highly polished, anterior part strongly, densely punctate.
Legs. Hind coxa shiny with superficial punctures. Spines on outer side of hind tibia long and dense. Inner spur of hind tibia nearly half length of hind basitarsus, outer spur 1/3 length of hind basitarsus. Basitarsus of hind leg a little shorter than tarsomeres 2–4 (13.0:15.0).
Wings. Pterostigma 2.3× as long as its widest part ( Fig. 34b View FIGURE 34 ). Vein 1-R1 1.1× longer than pterostigma, 4.8× as long as its distance from apex of marginal cell. Vein r arising from middle of pterostigma, perpendicular to pterostigma, 0.7× as long as width of pterostigma, r indistinctly longer than 2-SR, distinctly angled at meeting, 2-M half length of 2-SR and slightly longer than 1-SR and as long as 2-SR+M, m-cu weakly longer than r. First discal cell of fore wing 1.1× wider than high. Second discal cell of hind wing 1.6× wider than high. Vein cu-a strongly curved ( Fig. 34c View FIGURE 34 ).
Metasoma. 0.9× longer than mesosoma. T1 ( Fig. 34h View FIGURE 34 ) parallel-sided, distinctly widened before apex, its length weakly longer than hind width, basal one third indistinctly concave, polished, turned-over part weakly transverse, strongly rugose, medio-apical tubercle polished. T2 rugose with dispersed punctures, transverse, 5.5× wider than long in middle, strongly curved apically, suture between T2 and T3 broad. T3 2.0× longer than T2. Tergites posterior to T2 polished, shiny, and sparsely pubescent. Hypopygium not longer than apex of metasoma. Ovipositor sheath 1.3× longer than hind tibia, thin and nearly parallel-sided, ovipositor weakly curved throughout, without apical attenuation.
Colour. Black ( Fig. 34a View FIGURE 34 ). Tegula black. Palpi and spurs whitish. Flagellum and ovipositor brown, scape testaceous. Ovipositor sheath brown. Labrum dark reddish brown and mandible yellowish towards apex. Legs bright reddish yellow, fore and mid coxae yellowish brown, hind coxa black and apical fifth of hind tibia and hind tarsus more or less dark reddish yellow. Wing membrane hyaline, vein 1-R1 and pterostigma brown, C+SC+R yellow, r, 2-SR, and 2-M light brown and other alar veins almost colourless, pterostigma with whitish basal spot.
Variation. Body length 2.0– 2.9 mm, fore wing length 2.4–3.0 mm. Areola on propodeum of some specimens from Liaoning with transverse carinae.
Male. Body length 2. 8 mm, fore wing length 2.7 mm. Similar to female, except: T1 polished and weakly constricted posteriorly; T2 less transverse, 4.0× wider than long in middle, and penultimate antennomere 2.0× longer than wide.
Host. Unknown.

Distribution. Eastern Palaearctic [ China: Heilongjiang, Jilin, Liaoning, Shandong, Sichuan]; Oriental [ China: Zhejiang].
Etymology. The specific name “ latitergita ” derived from the Latin “latus” and “tergitus”, referring to T2 very wide.
Remarks. This species is similar to D. molestae (Muesebeck) , but differs in the following: T1 without median fovea on the apical half (the latter with); T2 5.5× wider than long in middle (the latter 4.0×); and hind femur bright reddish yellow (the latter brown to blackish brown).
