( Figs 40 , 68 ) Description. Holotype . Female. Body length 2.5 mm , fore wing length 3.1 mm . Head. Transverse in dorsal view, 2.1× as wide as long, 0.9× as wide as mesoscutum ( Fig. 40e ). Temple shiny with distinct punctures, strongly constricted behind eyes from dorsal view. Face ( Fig. 40i ) transverse, 0.8× as high as wide, shiny with shallow punctures, inner margins of eyes parallel-sided. Ocelli relatively small, 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 = 3.5:1.7:4.0. Antenna ( Fig. 40b ) distinctly longer than body length, penultimate antennomere 1.8× longer than wide. Mesosoma. Length:width:height = 44.0:29.0:29.0. Disc of mesonotum ( Fig. 40g ) a little shiny, with strong, dense punctures. Scutellar sulcus weakly curved, very narrow with carinae inbetween. Scutellum shiny with sharp, sparse punctuation. Propodeum ( Fig. 40c ) a little shiny, relatively long, with ill-defined pentagonal areolation which closed at anterior end and with a short median carina anteriorly, three posterior fields a little shiny and with a number of rugae, shiny and with dispersed rugose punctures anterio-laterally. Mesopleuron highly polished, anterior part sharply punctate. Legs. Hind coxa shiny with shallow punctures. Spines on outer side of hind tibia long and sparse. Inner spur of hind tibia 2/5 length of hind basitarsus, outer spur 1/3 length of hind basitarsus. Basitarsus of hind leg weakly shorter than tarsomeres 2–4 (20.0:21.5). Wings. Pterostigma 3.0× as long as its widest part ( Fig. 40d ). Vein 1-R1 1.2× longer than pterostigma, 7.0× as long as its distance from apex of marginal cell. Vein r arising from apex of pterostigma, distinctly inclined outwards, weakly longer than width of pterostigma, r weakly longer than 2-SR, curved at meeting, 2-M half length of 2-SR and slightly longer than 1-SR and as long as 2-SR+M, m-cu shorter than r. First discal cell of fore wing 1.2× wider than high. Second discal cell of hind wing 2.0× wider than high. Vein cu-a straight ( Fig. 40f ). Metasoma. 1.1× longer than mesosoma. T1 ( Fig. 40h ) parallel-sided, weakly widened before apex, 1.5× longer than hind width, basal 1/3 indistinctly concave, rugulose, turned-over part a little longer than wide, strongly rugose, longitudinal striate on lateral corners, medio-apical tubercle polished. T2 nearly lunule-shaped, poorly defined, rugulose laterally, polished at middle, 2.5× wider than long in middle, strongly curved apically, suture between T2 and T3 broad. T3 1.3× longer than T2. Tergites posterior to T2 polished, shiny, and sparsely pubescent. Hypopygium long. Ovipositor sheath 1.5× longer than hind tibia, thin and parallel-sided, ovipositor very thin, long (0.9× as long as body length), slightly curved at apex, without apical attenuation. Colour. Black, tergites nearly yellow to slightly reddish yellow entirely except apical several tergites black ( Fig. 40a, h ). Tegula, palpi and spurs whitish. Antenna yellowish brown, tending to be yellow basally. Ovipositor sheath brown. Labrum and mandible yellow. Legs yellow, fore and mid coxae yellow, hind coxa and femur reddish yellow, apical half of hind tibia and tarsus dark reddish yellow. Wing membrane hyaline, vein C+SC+ R and pterostigma brown, 1-R1 and alar veins almost colourless, pterostigma with whitish basal spot. Male. Unknown. Host. Unknown. Material examined ( ZJUH ). Holotype : ♀ , Nanxizheng , Hekou , Yunnan , 2003.VII.20–21 , Xu Zaifu, No. 20055264. FIGURE 40. Dolichogenidea lunatus Liu & Chen , sp. nov. , female, holotype. a. habitus, lateral view; b. antenna; c. propodeum, dorsal view; d. fore wing; e. head, dorsal view; f. hind wing; g. mesosoma, dorsal view; h. metasoma, dorsal view; i. head, frontal view. Scale line = 0.5 mm. Distribution. Oriental [ China : Yunnan ]. Etymology. The specific name “ lunatus ” derived from the Latin “lunatus”, referring to T2 lunule-shaped. Remarks. This species is similar to D. numenes Nixon , but differs in the following: ovipositor thin, without apical attenuation (the latter thick, with attenuated tip); T2 more or less rugulose (the latter polished); and T1 indistinctly narrowed towards base (the latter rather narrowed).
