( Figs 53 View FIGURE 53 , 69 View FIGURE 69. 61–75 )
Description. Holotype. Female. Body length 2.0 mm, fore wing length 2.3 mm.
Head. Weakly transverse in dorsal view, 1.9× as wide as long, 0.9× as wide as mesoscutum ( Fig. 53d View FIGURE 53 ). Temple dull with coarse, dense punctures, slightly constricted behind eyes from dorsal view. Face ( Fig. 53h View FIGURE 53 ) transverse, 0.8× as high as wide, relatively shiny, with small punctures, inner margins of eyes distinctly, but not strongly, converged towards apex. Posterior tangent to anterior ocellus just before posterior pair of ocelli, distance between fore and a hind ocellus almost as long as diameter of an hind ocellus, POL:OD:OOL = 3.5:1.9:4.0. Antenna almost as long as body length, penultimate antennomere 1.7× longer than wide.
Mesosoma. Length:width:height = 34.5:23.0:25.0. Disc of mesonotum ( Fig. 53e View FIGURE 53 ) a little shiny, with deep, dense punctures, spaces between punctures weakly rugulose on posterior imaginary notaulic courses. Scutellar sulcus nearly straight, narrow with carinae inbetween. Scutellum shiny with shallow punctures. Propodeum ( Fig. 53f View FIGURE 53 ) shiny, with well-defined areolation which open at anterior end and lateral carinae bifurcated, three posterior fields highly shiny and more or less polished with several indistinct punctures, anterio-lateral parts with much obsolescent punctuation. Mesopleuron highly polished, anterior part with shallow, sparse punctures.
Legs. Hind coxa shiny and almost impuctate. Spines on outer side of hind tibia dispersed. Inner spur half length of hind basitarsus, outer spur 1/3 length of hind basitarsus. Basitarsus of hind leg distinctly shorter than tarsomeres 2–4 (12.0:14.0).
Wings. Pterostigma small, 3.2× as long as its widest part ( Fig. 53b View FIGURE 53 ). Vein 1-R1 1.3× longer than pterostigma, 6.0× as long as its distance from apex of marginal cell. Vein r arising from middle of pterostigma, r perpendicular to pterostigma, 1.4× longer than width of pterostigma and 2-SR, angled with 2-SR at meeting, 2-M half length of 2-SR and almost as long as 1-SR, 2-SR+M as long as 2-SR, m-cu weakly shorter than r. First discal cell of fore wing slightly wider than high (16.5:14.5). Second discal cell of hind wing 2.2× wider than high. Vein cu-a curved ( Fig. 53c View FIGURE 53 ).
Metasoma. Almost as long as mesosoma. T1 ( Fig. 53g View FIGURE 53 ) parallel-sided, 1.4× longer than hind width, basal 1/3 concave, nearly polished, turned-over part nearly quadrate, strongly punctate-rugose medially, finely longitudinally striate on apical third. T2 weakly rugulose, 5.0× wider than long in middle, strongly curved apically. T3 1.7× longer than T2. Tergites posterior to T2 shiny, polished and with hairy punctures. Hypopygium not longer than apex of metasoma. Ovipositor sheath as long as length of hind femur, parallel-sided. Ovipositor thin, strongly curved, apical attenuation very short.
Colour. Black, tergites posterior to T2 dark brown ( Fig. 53a, g View FIGURE 53 ). Tegula brown. Palpi and spurs whitish.Antenna yellowish brown and ovipositor sheath dark brown. Labrum red and mandible honey yellow. Legs yellow, except fore and mid coxae, mid and hind trochanters, basal half of mid femur, hind femur, apical 1/3 of hind tibia infuscate. Wing membrane hyaline, vein 1-R1, apical C+SC+R, and upper border of pterostigma brown, most of C+SC+R whitish, pterostigma, r, 2-SR and 2-M honey yellow, other alar veins almost colourless.
Variation. Body length 1.9–2.6 mm, fore wing length 2.2–2.6 mm. Apical half to apical 2/3 of hind tibia blackish brown. Ovipositor sheath of one specimen distinctly wider towards apex.

Distribution. Oriental [ China: Fujian, Guangdong, Guizhou, Zhejiang].
Etymology. The specific name “ punctipila ” derived from the Latin “punct-” and “pilus”, referring to T3 with hairy punctures.
Remarks. This species is similar to D. angularis Song & Chen , but differs in the following: temple with coarse, dense punctures (the latter weakly punctate); face with small punctures (the latter with large punctures); and hind coxa almost impunctate (the latter rugose-punctate).
