( Figs 27 , 67 ) Description. Holotype . Female. Body length 2.1 mm , fore wing length 2.6 mm . Head. Transverse in dorsal view, nearly 2.0× as wide as long, weakly narrower than mesoscutum ( Fig. 27e ). Temple shiny and shallowly punctate, strongly constricted behind eyes from dorsal view. Face ( Fig. 27f ) 0.8× as high as wide, shiny, nearly impunctate, inner margins of eyes distinctly converged posteriorly. Hind ocelli distinctly larger than the anterior one, posterior tangent to anterior ocellus virtually touching posterior pair of ocelli, distance between fore and a hind ocellus as long as diameter of an hind ocellus, POL:OD:OOL = 3.5:2.0:4.5. Antenna slightly longer than body, penultimate antennomere 1.4× longer than wide. Mesosoma. Length:width:height = 35.0:23.8:24.0. Disc of mesonotum ( Fig. 27g ) shiny, with strong punctures which becoming denser and larger towards apex. Scutellar sulcus straight, broad with carinae inbetween. Scutellum shiny, with small shallow punctures. Propodeum ( Fig. 27d ) shiny, with well-defined areolation which open at anterior end, costulae well-defined, three posterior fields polished, anterio-lateral parts more or less smooth, indistinctly punctate. Mesopleuron highly polished, with shallow fine punctures anteriorly. Legs. Spines on outer side of hind tibia thin and long. Inner spur of hind tibia half of hind basitarsus, outer spur 2/5 length of hind basitarsus. Basitarsus of hind leg weakly shorter than tarsomeres 2–4. Wings. Pterostigma 3.3× as long as its widest part ( Fig. 27b ). Vein 1-R1 weakly longer than pterostigma, 5.3× as long as its distance from apex of marginal cell. Vein r arising from middle of pterostigma, perpendicular to pterostigma, 1.3× as long as width of pterostigma, r 1.8× longer than vein 2-SR, distinctly angled at meeting, 2-M 4/5 of 2-SR and longer than 1-SR, 2-SR+M nearly as long as 2-SR, m-cu a little shorter than r. First discal cell of fore wing as wide as high. Second discal cell of hind wing 1.4× wider than high. Vein cu-a incurved ( Fig. 27c ). Metasoma. Nearly as long as mesosoma. T1 ( Fig. 27h ) parallel-sided, weakly broad before apex, 1.3× longer than hind width, basal third indistinctly concave and weakly rugose, turned-over part quadrate, shiny with irregular short rugae besides the more or less distinct medio-longitudinal carina. T2 weakly evenly curved apically, weakly strigose, 3.8× wider than long in middle. T3 1.7× as long as T2. Tergites posterior to T2 highly polished, and shiny. Hypopygium not longer than apex of metasoma. Ovipositor sheath shorter than hind basitarsus (8.0:12.5), setae sparse and few, ovipositor straight, short, apical attenuation as long as the thickened, basal part and 1/4 length of hind basitatsus. Colour. Black ( Fig. 27a ). Tegula dark brown. Palpi and spurs whitish. Antenna and ovipositor sheath dark brown. Labrum light reddish brown and mandible more yellowish. Legs yellow to bright reddish yellow, except coxae black and basal half of hind femur darker. Wing membrane hyaline, vein 1-R1, C+SC+ R and upper border of pterostigma brown, pterostigma, r, 2-SR and 2-M light brown and other veins whitish. Variation. Body length 2.0– 2.3 mm , fore wing length 2.5–2.6 mm . Sometimes hind femur blackish brown dorsally. Male. Unknown. Host. Unknown. Material examined ( ZJUH ).

Distribution. Oriental [ China : Fujian , Guangdong , Zhejiang ]. Etymology. The specific name “ hemituba ” derived from the Latin adjective “hemi” and “tuba”, referring to its apical attenuation of the ovipositor as long as the thickened, basal part. Remarks. This species is similar to D. aso (Nixon) , but differs in the following: apical attenuation of ovipositor 1/4 length of hind basitarsus (the latter as long as); penultimate antennomere 1.4× longer than wide (the latter about 2.0×); and hind femur mainly bright reddish yellow (the latter infuscate).
