Description. Holotype. Female. Body length 2.2 mm, fore wing length 2.5 mm.
Head. Weakly transverse in dorsal view ( Fig. 4c View FIGURE 4 ), 1.9× as wide as long, nearly 0.9× as wide as mesoscutum. Temple a little shiny with shallow punctuation, strongly constricted behind eyes from dorsal view. Face ( Fig. 4d View FIGURE 4 ) transverse, 0.8× as high as wide, shiny with shallow, indistinct punctures, inner margins of eyes nearly parallel. Posterior tangent to anterior ocellus transceting posterior pair of ocelli, distance between fore and a hind ocellus slightly shorter diameter of a hind ocellus, POL:OD:OOL = 3.0:2.0:3.5. Last nine antennomeres missing.
Mesosoma. Length:width:height = 36.5:27.0:31.5. Disc of mesonotum ( Fig. 4g View FIGURE 4 ) a little shiny, strongly and coarsely punctate. Scutellar sulcus slightly curved, relatively broad with carinae inbetween. Scutellum evenly punctate, interspaces shiny and about as long as puncture diameter. Propodeum ( Fig. 4f View FIGURE 4 ) shiny, with well-defined areolation which closed at anterior end, costulae well-defined, three posterior fields polished and smooth, shiny and uneven with small hairy punctures anterio-laterally. Mesopleuron highly polished but punctate-rugose anteriorly.
Legs. Hind coxa shiny, almost polished with indistinct small punctures. Spines on outer side of hind tibia long and relatively dense. Inner spur of hind tibia 1/3 length of hind basitarsus, outer spur 1/4 length of hind basitarsus. Basitarsus of hind leg weakly shorter than tarsomeres 2–4 (14.0:15.0).
Wings. Pterostigma 2.8× as long as its widest part ( Fig. 4b View FIGURE 4 ). Vein 1-R1 1.2× longer than pterostigma, 5.0× as long as its distance from apex of marginal cell. Vein r arising from middle of pterostigma, slightly oblique outwards, 1.2× as long as width of pterostigma, vein r 1.3× longer than 2-SR, distinctly angled at meeting, 2-M half-length of 2-SR and weakly shorter than 1-SR and 2-SR+M, m-cu 0.8× length of r. First discal cell of fore wing weakly wider than high (17.5:16.5). Vein cu-a strongly oblique ( Fig. 4e View FIGURE 4 ).
Metasoma. As long as mesosoma. T1 ( Fig. 4h View FIGURE 4 ) strongly widened towards apex, length as long as hind width, basal third concave and nearly polished, turned-over part transverse, strongly rugose, shiny and polished on hind tubercle. T2 strongly rugose as T1, 2.7× wider than long in middle, nearly straight apically. T3 0.8× as long as T2. Tergites posterior to T2 highly polished, shiny, and sparsely pubescent. Hypopygium not longer than apex of metasoma. Ovipositor sheath 1.2× longer than hind basitarsus, thin and parallel-sided, ovipositor thin, without apical attenuation.
Colour. Black ( Fig. 4a View FIGURE 4 ). Tegula black. Palpi and spurs whitish. Flagellum and ovipositor sheath brown, scape dark brown. Labrum light reddish brown and mandible dirty yellow. Legs bright reddish yellow, coxae black, fore and hind femora more or less blackish laterally. Wing membrane hyaline, vein 1-R1 and upper border of pterostigma dark brown, C+SC+ R and pterostigma yellowish brown, vein r, 2-SR and 2-M yellow and other alar veins more or less whitish yellow, pterostigma without basal spot.
Male. Unknown.
Host. Unknown.
Material examined ( ZJUH). Holotype: 1♀, Mt. Longxi, Jiangle , Fujian, 1991.VII.8, Liu Changming, No. 69855.
Distribution. Oriental [ China: Fujian].
Etymology. The specific name “ altithoracica ” derived from the Latin adjective “altus” and noun “thoracica”, referring to its thorax relatively high.
Remarks. This species is closely similar to D. hemitheae (Wilkinson) , but differs in the following: pterostigma without basal spot (the latter with); face shallowly, indistinctly punctate (the latter strongly, closely punctate); and T3 totally smooth (the latter weakly rugose).
