(Figs 24, 67)
Description. Holotype. Female. Body length 2.0 mm, fore wing length 2.3 mm.
Head. Transverse in dorsal view, 2.0× as wide as long, nearly as wide as mesoscutum (Fig. 24i). Temple shiny with shallow punctures, weakly constricted behind eyes from dorsal view. Face (Fig. 24f) transverse, 0.8× as high as wide, dull, rough with shallow punctures, inner margins of eyes nearly parallel-sided. Ocelli small, posterior tangent to anterior ocellus weakly transecting posterior pair of ocelli, distance between fore and a hind ocellus as long as diameter of an hind ocellus, POL:OD:OOL = 3.0:1.5:4.0. Antenna weakly longer than body length, penultimate antennomere 1.4× longer than wide.
Mesosoma. Length:width:height = 35.5:23.5:25.0. Disc of mesonotum (Fig. 24h) shiny, with deep, dense punctures. Scutellar sulcus sinuate, slightly curved downward medially and upward laterally, broad with carinae inbetween. Scutellum shiny, with relatively dense punctures laterally. Propodeum (Fig. 24c) shiny, with well-defined pentagonal areolation which closed at at anterior end, three posterior fields highly shiny and polished, anterio-lateral parts with silvery setae, no any punctures. Mesopleuron highly polished, anterior part with large, dense punctures.
Legs. Hind coxa shiny, without punctures. Spines on outer side of hind tibia stout, dispersed. Inner spur of hind tibia half length of hind basitarsus, outer spur 1/3 length of hind basitarsus. Basitarsus of hind leg a little shorter than tarsomeres 2–4 (13.5:15.0).
Wings. Pterostigma 2.7× as long as its widest part (Fig. 24b). Vein 1-R1 1.2× longer than pterostigma, 6.0× as long as its distance from apex of marginal cell. Vein r arising from middle of pterostigma, perpendicular to the latter, and 0.7× as long as width of it, r as long as 2-SR, angled at meeting, 2-SR weakly incurved, 2-M 2/3 length of 2-SR and weakly longer than 1-SR and as long as 2-SR+M, m-cu distinctly longer than r. First discal cell of fore wing as wide as high. Second discal cell of hind wing 2.0× wider than high. Vein cu-a strongly curved (Fig. 24e).
Metasoma. As long as mesosoma. T1 (Fig. 24d) weakly widened towards apex, indistinctly constricted posteriorly, 1.4× longer than hind width, basal 1/3 indistinctly concave, rugulose, turned-over part weakly longer than wide, punctate-rugose. T2 weakly rugulose, 3.3× wider than long in middle, nearly straight apically. T3 1.4× longer than T2. Tergites posterior to T2 polished, shiny, and pubescent. Hypopygium distinctly shorter than apex of metasoma. Ovipositor sheath (Fig. 24g) 0.7× as long as hind femur, thin and parallel-sided.
Colour. Black (Fig. 24a). Tegula dark brown. Palpi yellowish brown and spurs whitish. Antenna and ovipositor sheath brown. Labrum dark brown and mandible reddish brown. Legs infuscate to brown except most of fore femur, fore tibia, fore tarsus, apex of mid femur, basal mid tibia, mid tarsus, basal 1/4 of hind tibia honey yellow. Wing membrane hyaline, weakly brownish, vein 1-R1, C+SC+ R and upper border of pterostigma brown, pterostigma and another alar veins honey yellow, pterostigma without whitish basal spot.
Male. Unknown.
Host. Unknown.
Material examined (ZJUH). Holotype: ♀, Sanchahe, Yunnan, 1981.IV.12, He Junhua, No. 811835.
Distribution. Oriental [China: Yunnan].
Etymology. The specific name “ fluctisulcus ” derived from the Latin “fluctus” and “sulcus”, referring to scutellar sulcus slightly curved downward medially and upward laterally.
Remarks. This species is similar to D. orelia Nixon, but differs in the following: apical segment of the fore tarsus without a distinct spine (the latter with); T2 weakly rugulose (the latter strongly rugose as T1); and pterostigma honey yellow (the latter dark brown).
