( Figs 23 View FIGURE 23 , 67 View FIGURE 67. 21–35 )
Description. Holotype. Female. Body length 2.3 mm, fore wing length 2.6 mm. Head. Transverse in dorsal view, 2.1× as wide as long, nearly as wide as mesoscutum ( Fig. 23c View FIGURE 23 ). Temple shiny with shallow punctures, slightly constricted behind eyes from dorsal view. Face ( Fig. 23f View FIGURE 23 ) transverse, 0.8× as high as wide, a little shiny, with small punctures, inner margins of eyes subparallel. Ocelli small, posterior tangent to anterior ocellus hardly touching posterior pair of ocelli, distance between fore and a hind ocellus distinctly longer than diameter of an hind ocellus, POL:OD:OOL = 4.0:1.5:5.0. Antenna distinctly shorter than body length, penultimate antennomere subcubic.
Mesosoma. Length:width:height = 36.5:24.5:25.0. Disc of mesonotum ( Fig. 23d View FIGURE 23 ) a little shiny, with large, dense punctures, spaces between punctures weakly rugulose on posterior imaginary notaulic courses. Scutellar sulcus evenly curved, narrow with carinae inbetween. Scutellum shiny, smooth with shallow punctures laterally. Propodeum ( Fig. 23e View FIGURE 23 ) shiny, with less well-defined lozenge-shaped areolation which open at at anterior end and along by some rugosity, three posterior fields shiny and polished with some rugae, anterio-lateral parts shiny, uneven with dispersed shallow punctures. Mesopleuron highly polished, anterior part with sharp, relatively dense punctures.
Legs. Hind coxa relatively dull, with indistinct punctures. Spines on outer side of hind tibia long and dispersed. Inner spur nearly half length of hind basitarsus, outer spur 1/3. Basitarsus of hind leg nearly as long as tarsomeres 2–4.
Wings. Pterostigma 2.7× as long as its widest part ( Fig. 23b View FIGURE 23 ). Vein 1-R1 1.3× longer than pterostigma, 5.0× as long as its distance from apex of marginal cell. Vein r arising from apex of pterostigma, r extremely weakly inclined outward, nearly as long as width of pterostigma, as long as 2-SR, distinctly angled at meeting, 2-M less than half length of 2-SR and as long as 1-SR and a little shorter than 2-SR+M, m-cu as long as width of pterostigma. First discal cell of fore wing 1.2× wider than high. Second discal cell of hind wing 2.0× wider than high. Vein cu-a strongly curved ( Fig. 23g View FIGURE 23 ).
Metasoma. As long as mesosoma. T1 ( Fig. 23h View FIGURE 23 ) nearly parallel-sided, 1.3× longer than hind width, basal 1/3 concave, nearly polished, turned-over part weakly transverse, strongly rugose, weakly longitudinally striate on apical third. T2 weakly rugulose with transverse rows of minute punctures, nearly 4.0× wider than long in middle, strongly curved apically, median length 2.0× longer than lateral length. T3 1.5× longer than T2. Tergites posterior to T2 shiny, slightly smooth, and relatively densely pubescent. Hypopygium distinctly shorter than apex of metasoma. Ovipositor sheath 1.2× as long as length of hind tibia, nearly parallel-sided.
Colour. Black ( Fig. 23a View FIGURE 23 ). Tegula brown. Palpi yellowish brown and spurs whitish yellow. Antenna and ovipositor sheath dark brown. Labrum light yellowish brown and mandible more yellowish apically. Legs dark brown, except fore leg, apex of middle femur, basal 1/3 of mid tibia, and basal 1/3 of hind tibia light yellowish brown. Wing membrane hyaline, vein 1-R1, C+SC+R, and upper border of pterostigma dark brown, remaining border of pterostigma, r, 2-SR and 2-M light yellowish brown, other alar veins almost colourless, pterostigma whitish with dark border.
Male. Unknown.
Host. Unknown.
Material examined ( ZJUH). Holotype: ♀, Ruili , Yunnan, 1981.V.1, He Junhua, No. 812419.
Distribution. Oriental [ China: Yunnan].
Etymology. The specific name “ flexitergita ” derived from the Latin “flexus” and “tergitus”, referring to T2 strongly curved apically.
Remarks. This species is similar to D. subgentilis Tobias & Long, 1990 , but differs in the following: first discal cell of fore wing 1.2× wider than high (the latter as wide as high); temple slightly constricted behind eyes from dorsal view (the latter strongly); and distance between hind ocelli longer than the distance from the eye to a hind ocellus (the latter shorter).
