(Figs 8, 66)
Description. Holotype. Female. Body length 2.0 mm, fore wing length 2.3 mm.
Head. Weakly transverse in dorsal view, 1.8× as wide as long, 0.9× as wide as mesoscutum (Fig. 8h). Temple shiny with superficial punctures, slightly constricted behind eyes from dorsal view. Face (Fig. 8d) transverse, 0.8× as high as wide, shiny, shallowly punctate, with a short sulcus basal-medially, inner margins of eyes subparallel, distinctly tumescent medially. Ocelli small, posterior tangent to anterior ocellus distinctly transecting posterior pair of ocelli, distance between fore and a hind ocellus weakly shorter than diameter of an hind ocellus, POL:OD:OOL = 3.6:1.8:4.0. Antenna (Fig. 8j) a little shorter than body length, penultimate antennomere 1.3× longer than wide.
Mesosoma. Length:width:height = 34.0:23.5:24.5. Disc of mesonotum (Fig. 8g) shiny, with strong punctures. Scutellar sulcus straight, relatively broad with carinae inbetween. Scutellum highly shiny and polished without punctures. Propodeum (Fig. 8c) shiny, with well-defined areolation which open at at anterior end, lateral carinae of areola strongly bifurcated medially, three posterior fields highly shiny and polished, anterio-laterally highly shiny, slightly uneven. Mesopleuron highly polished, anterior part with superficial, sparse punctures.
Legs. Hind coxa highly shiny, polished, and impunctate. Spines on outer side of hind tibia relatively dense. Inner spur nearly half length of hind basitarsus, outer spur 1/3. Basitarsus of hind leg weakly longer than tarsomeres 2–4 (13.8:13.0).
Wings. Pterostigma 2.9× as long as its widest part (Fig. 8b). Vein 1-R1 1.1× longer than pterostigma, 4.4× as long as its distance from apex of marginal cell. Vein r arising from middle of pterostigma, evenly rounded at the meeting with 2-SR, 2-M half-length of 2-SR and as long as 1-SR and 2-SR+M, m-cu almost as long as r. First discal cell of fore wing as wide as high. Second discal cell of hind wing 1.9× wider than high (Fig. 8i). Vein cu-a strongly curved.
Metasoma. 1.2× longer than mesosoma. T1 (Fig. 8e) distinctly, but not strongly, constricted at apex, 1.6× longer than hind width, basal one third concave, polished, turned-over part weakly longer than wide, shiny with several small punctures and very weak rugulosities posteriorly. T2 entirely shiny and polished, 3.0× wider than long in middle, nearly straight apically. T3 1.3× longer than T2. Tergites posterior to T2 highly polished, shiny, and sparsely pubescent. Hypopygium a little shorter than apex of metasoma. Ovipositor sheath (Fig. 8f) nearly 0.9× as long as length of hind femur, parallel-sided. Apical attenuation of ovipositor long, nearly as long as the thickened, basal part and hind basitarsus.
Colour. Black (Fig. 8a). Tegula black. Palpi reddish yellow and spurs whitish. Flagellum and pedicel brown, scape and ovipositor sheath dark brown. Labrum and mandible black, except apices of mandible dark reddish yellow. Legs bright reddish yellow, except all coxae dark reddish brown to black, trochanters, basal half of mid femur, most of hind femur, posterior 1/4 of hind tibia and tarsus infuscate. Wing membrane hyaline, weakly brownish, vein 1-R1, C+SC+ R and pterostigma brown, other alar veins whitish yellow.
Male. Unknown.
Host. Unknown.
Material examined (ZJUH). Holotype: 1♀, Pingtang, Guizhou, 1990, Liu Zhibang, No. 907897.
Distribution. Oriental [China: Guizhou].
Etymology. The specific name “ atarsi ” derived from the Latin “a-” and “tarsi”, referring to basitarsus of hind leg abnormally weakly longer than tarsomeres 2–4.
Remarks. This species is similar to D. prodeniae Viereck, but differs in the following: T2 4/5 length of T3 (the latter half as long as T3); apical attenuation as long as basitarsus (the latter equal to the fourth segment of the hind tarsus); and vertex at most shallowly punctate (the latter largely, finely rugose).
