( Figs 44 View FIGURE 44 , 68 View FIGURE 68. 36–60 )
Description. Holotype. Female. Body length 2.1 mm, fore wing length 2.5 mm.
Head. Transverse in dorsal view, 2.0× as wide as long, 0.9× as wide as mesoscutum ( Fig. 44d View FIGURE 44 ). Temple a little shiny with shallow punctures, strongly constricted behind eyes from dorsal view. Face ( Fig. 44f View FIGURE 44 ) transverse, 0.8× as high as wide, shiny, with small punctures, inner margins of eyes distinctly, but not strongly, constricted posteriorly. Ocelli small, posterior tangent to anterior ocellus virtually touching posterior pair of ocelli, distance between fore and a hind ocellus nearly as long as diameter of an hind ocellus, POL:OD:OOL = 3.0:2.0:4.0. Antenna ( Fig. 44h View FIGURE 44 ) a little longer than body length, penultimate antennomere 2.4× longer than wide.
Mesosoma. Length:width:height = 41.0:25.0:24.5. Disc of mesonotum ( Fig. 44i View FIGURE 44 ) a little shiny, with strong punctures which becoming sparser on posterior half. Scutellar sulcus weakly curved, narrow with carinae inbetween. Scutellum shiny, with shallow punctures laterally. Propodeum ( Fig. 44g View FIGURE 44 ) shiny, with well-defined areolation which opened at anterior end, rugose-punctate medio-anteriorly, three posterior fields highly shiny and with more or less rugae, independently punctate anterio-laterally. Mesopleuron highly polished, anterior part distinctly, sparsely punctate.
Legs. Hind coxa shiny, with extremely shallow punctures. Spines on outer side of hind tibia sparse. Inner spur of hind tibia nearly half length of hind basitarsus, outer spur 1/3 length of hind basitarsus. Basitarsus of hind leg a little shorter than tarsomeres 2–4 (13.0:15.0).
Wings. Pterostigma small, 3.0× as long as its widest part ( Fig. 44b View FIGURE 44 ). Vein 1-R1 1.2× longer than pterostigma, 6.3× as long as its distance from apex of marginal cell. Vein r arising from apex of pterostigma, perpendicular to the latter, and as long as width of it, r 1.3× longer than 2-SR, angled at meeting, 2-M half length of 2-SR and weakly shorter than 1-SR and 2-SR+M, m-cu as long as r. First discal cell of fore wing 1.1× wider than high. Second discal cell of hind wing 1.5× wider than high. Vein cu-a strongly curved ( Fig. 44c View FIGURE 44 ).
Metasoma. 0.8× as long as mesosoma. T1 ( Fig. 44g View FIGURE 44 ) weakly widened towards apex, indistinctly constricted posteriorly, 1.4× longer than hind width, basal 1/3 indistinctly concave, rugulose, turned-over part quadrate, strongly rugose, indistinctly longitudinally striate laterally. T2 rugose medially as T1, longitudinally striate laterally, 3.1× wider than long in middle, weakly curved apically. T3 nearly 1.4× longer than T2. Tergites posterior to T2 polished, shiny, and pubescent. Hypopygium distinctly shorter than apex of metasoma. Ovipositor sheath as long as length of hind basitarsus, thin and parallel-sided, ovipositor a little thick basally, with an apical attenuation.
Colour. Black, tergites posterior to T2 brown ( Fig. 44a, g View FIGURE 44 ). Tegula brown. Palpi and spurs whitish yellow. Antenna and ovipositor sheath brown. Labrum and mandible reddish brown. Legs bright reddish yellow, except coxae black, basal hind femur slightly blackish, apical third of hind tibia and tarsus infuscate. Wings weakly milky, vein 1-R1 and C+SC+R brown, pterostigma, r, 2-SR, and 2-M honey yellow, and other alar veins colourless, pterostigma without whitish basal spot.
Variation. Body length 1.9–2.5 mm, fore wing length 2.5–2.8 mm. Tergites posterior to T2 varied from yellowish red to dark brown, hind femur yellow to infuscate.
Male. Body length 1.9–2.1 mm, fore wing length 2.3–2.6 mm. Similar to female, except: pterostigma whitish with dark border; T1 nearly polished to apx; hind femur always infuscate; and penultimate antennomere 3.0× longer than wide.
Material examined ( ZJUH). Holotype: ♀, Guangzhou , Guangdong, 1979.IV.10, Wu Jianfen, ex Artona funeralis (Butler) , No. 790549 . Paratypes: 1♀ 3♂♂, same data as holotype ; 4♀♀ 1♂, Guangzhou , Guangdong, 1979. IV.24, Wu Jianfen, ex Artona funeralis (Butler) , No. 790550 ; 3♀♀ 1♂, Guangzhou , Guangdong, 1979.IX.10, Wu Jianfen, ex Artona funeralis (Butler) , No. 790015 .
Distribution. Oriental [ China: Guangdong].
Etymology. The specific name “ multicolor ” derived from the Latin “multi” and “color”, referring to colour of tergites posterior to T2 varied from yellowish red to dark brown.
Remarks. This species is similar to D. longialba Liu & Chen , sp. nov., but differs in the following: penultimate antennomere 2.4× longer than wide (the latter 1.5×); hind femur at most infuscate (the latter black); and hypopygium distinctly shorter than apex of metasoma (the latter not).
