(Figs 6, 66)
Description. Holotype. Female. Body length 2.3 mm, fore wing length 2.6 mm.
Head. Transverse in dorsal view, 2.0× as wide as long, 0.9× as wide as mesoscutum (Fig. 6c). Temple shiny with shallow punctures, weakly constricted behind eyes from dorsal view. Face (Fig. 6f) transverse, 0.8× as high as wide, a little shiny with small punctures, inner margins of eyes a little constricted towards apex. Ocelli relatively large, posterior tangent to anterior ocellus virtually touching posterior pair of ocelli, distance between fore and a hind ocellus weakly shorter than diameter of an hind ocellus, POL:OD:OOL = 3.5:2.0:3.5. Antenna a little shorter than body length, penultimate antennomere 1.2× longer than wide.
Mesosoma. Length:width:height = 38.5:25.0:27.0. Disc of mesonotum (Fig. 6d) shiny with distinct, dense punctures, parts along apical margin impunctate. Scutellar sulcus curved, rather narrow with carinae inbetween. Scutellum highly shiny, polished except several minute punctures. Propodeum (Fig. 6e) shiny, with well-defined areolation whichopen at at anterior end and U-shaped at bottom, three posterior fields shiny and polished, medioanteriorly polished, latero-anterior parts shiny with several minute hairy punctures. Mesopleuron highly polished, anterior part with distinct, sparse punctures.
Legs. Hind coxa shiny with indistinct punctures. Spines on outer side of hind tibia long, dense. Inner spur nearly half length of hind basitarsus, outer spur 1/3. Basitarsus of hind leg as long as tarsomeres 2–4.
Wings. Pterostigma 2.6× as long as its widest part (Fig. 6b). Vein 1-R1 1.3× longer than pterostigma, 7.7× as long as its distance from apex of marginal cell. Vein r arising from middle of pterostigma, r perpendicular to pterostigma, weakly shorter than width of pterostigma, indistinctly longer than 2-SR, distinctly angled with 2-SR at meeting, 2-M half-length of 2-SR and nearly as long as 1-SR and 2-SR+M, m-cu as long as 2-SR. First discal cell of fore wing 1.1× wider than high. Second discal cell of hind wing (Fig. 6g) 1.5× wider than high. Vein cu-a weakly curved.
Metasoma. Almost as long as mesosoma. T1 (Fig. 6h) parallel-sided, 1.3× longer than hind width, basal 1/4 concave, polished, turned-over part quadrate, largely polished medially, weakly longitudinally striate laterally. T2 shiny and polished, 4.3× wider than long in middle, strongly curved apically. T3 1.2× longer than T2. Tergites posterior to T2 shiny, polished and pubescent. Hypopygium shorter than apex of metasoma. Ovipositor sheath 1.6× length of hind tibia, thin and parallel-sided, abruptly curved distally.
Colour. Black (Fig. 6a). Tegula dark brown. Palpi and spurs pale yellowish brown. Antenna and ovipositor sheath dark brown. Labrum light reddish brown and mandible reddish yellow. Legs brown to dark brown, except most of fore leg, apex of mid femur, mid tibia, mid tarsus, and basal half-length of hind tibia bright reddish yellow. Wing membrane hyaline, weakly brownish, vein 1-R1, C+SC+R, and upper border of pterostigma brown, pterostigma yellowish brown, other alar veins light yellowish brown.
Male. Unknown.
Host. Unknown.
Material examined (ZJUH). Holotype: 1♀, Huanghuacong to Tongmu, Mt. Wuyi, Fujian, 1983.VIII.5, Ma Yun, No. 832697.
Distribution. Oriental [China: Fujian].
Etymology. The specific name “ apicurvus ” derived from the Latin “apic-” and “curvus”, referring to ovipositor sheath abruptly curved distally.
Remarks. This species is similar to D. longituba Song & Chen, but differs in the following: ovipositor 2/5 length of body (the latter nearly as long as); vannal lobe beyond its widest part of hind wing straight (the latter evenly convex); and scutellar sulcus curved (the latter straight).
