( Figs 64 View FIGURE 64 , 69 View FIGURE 69. 61–75 )
Description. Holotype. Female. Body length 2.1 mm, fore wing length 2.3 mm.
Head. Transverse in dorsal view, 2.0× as wide as long, nearly 0.9× as wide as mesoscutum ( Fig. 64d View FIGURE 64 ). Temple relatively dull, weakly rough with large, indistinct punctures, slightly constricted behind eyes from dorsal view. Face ( Fig. 64e View FIGURE 64 ) transverse, 0.8× as high as wide, slightly shiny, a little rough with shallow punctures, inner margins of eyes parallel-sided, with short sulcus medio-anteriorly. Ocelli large, posterior tangent to anterior ocellus indistinctly transecting posterior pair of ocelli, distance between fore and a hind ocellus weakly shorter than diameter of an hind ocellus, POL:OD:OOL = 2.7:2.0:3.8. Antenna as long as body length, penultimate antennomere 1.3× longer than wide.
Mesosoma. Length:width:height = 38.0:25.0:27.0. Disc of mesonotum ( Fig. 64c View FIGURE 64 ) shiny, with sharp, dense punctures. Scutellar sulcus nearly straight, narrow with dense carinae inbetween. Scutellum shiny with shallow, sparse punctures. Propodeum ( Fig. 64h View FIGURE 64 ) shiny, with well-defined lozenge-shaped areolation which open at at anterior end and V-shaped at bottom, three posterior fields highly shiny and nearly polished, lateral-anterior parts with indistinct punctures. Mesopleuron highly polished, anterior part with shallow, sparse punctures.
Legs. Hind coxa shiny and polished. Spines on outer side of hind tibia sparse. Inner spur half length of hind basitarsus, outer spur nearly 2/5 length of hind basitarsus. Basitarsus of hind leg a little shorter than tarsomeres 2–4 (13.0:15.0).
Wings. Pterostigma relatively large, 2.5× as long as its widest part ( Fig. 64b View FIGURE 64 ). Vein 1-R1 1.2× longer than pterostigma, 5.8× as long as its distance from apex of marginal cell. Vein r arising from middle of pterostigma, r weakly inclined outwards, indistinctly shorter than width of pterostigma, as long as or weakly longer than 2-SR, indistinctly angled with 2-SR at meeting, 2-M 3/5 length of 2-SR and a little longer than 1-SR and as long as 2- SR+M, m-cu as long as r. First discal cell of fore wing 1.1× wider than high. Second discal cell of hind wing 1.8× wider than high. Vein cu-a strongly curved ( Fig. 64g View FIGURE 64 ).
Metasoma. Nearly as long as mesosoma. T1 ( Fig. 64f View FIGURE 64 ) parallel-sided, weakly widened towards apex, 1.2× longer than hind width, basal 1/3 concave, polished, turned-over part weakly transverse, strongly punctate-rugose medially, weakly rugulose apically, hind tubercle polished. T2 rough with extremely weak but regular rugae and a row of indistinct punctures medio-apically, strongly transverse, 5.0× wider than long in middle, strongly curved apically. T3 2.0× longer than T2. Tergites posterior to T2 a little shiny, polished and with minute hairy bumps. Hypopygium not longer than apex of metasoma. Ovipositor sheath as long as length of hind tibia, thin and weakly broad at apex. Ovipositor thin, weakly curved apically, taped towards apex.
Colour. Black ( Fig. 64a View FIGURE 64 ). Tegula black. Palpi yellowish brown and spurs whitish yellow. Antenna and ovipositor sheath dark brown. Labrum and mandible dark brown. Legs brown to black, except fore leg, apical half of mid femur, mid tibia, mid tarsus, and basal two thirds of hind tibia bright reddish yellow. Wing membrane hyaline, vein 1-R1, C+SC+R, and upper border of pterostigma brown, remaining parts of pterostigma, r, 2-SR and 2-M yellowish brown, other alar veins whitish.
Variation. Body length 1.9–2.5 mm, fore wing length 2.3–2.7 mm. Tergites dark brown to black. Specimens from Sichuan and Yunnan becoming markedly smoother towards apex, T2 nearly polished.
Male. Body length 2.0– 2.2 mm, fore wing length 2.3–2.4 mm. Similar to female, except: T2 less transverse, 2.6× wider than long; antenna distinctly longer than body length, penultimate antennomere 2.6× longer than wide; and pterostigma more whitish with dark border.
Host. Unknown.

Distribution. Oriental [ China: Fujian, Guangdong, Guangxi, Zhejiang].
Etymology. The specific name “ victoria ” derived from the Latin, referring to propodeum distinctly V-shaped at bottom.
Remarks. This species is similar to D. angularis Song & Chen , but differs in the following: areolation V-shaped at bottom (the latter U-shaped); T2 half length of T3 (the latter 0.8×); and posterior tangent to anterior ocellus indistinctly transecting posterior pair of ocelli (the latter hardly touching).
