(Figures 4, 98)  
 Description. Holotype. Female. Body length 1.9 mm, fore wing length 2.3 mm.   
 Head. Transverse in dorsal view, 1.9× as wide as long, 1.1× as long as mesoscutum. Eyes 3.0× longer than temple in dorsal view. Temple shiny with shallow punctures, strongly constricted behind eyes. Face 0.8× as high as wide, shiny with superficial punctures, inner margin of eyes subparallel. Ocelli large, posterior tangent to anterior ocellus hardly touching posterior ocelli, distance between fore and hind ocellus shorter than diameter of hind ocellus, POL:OD:OOL=2.5:2.0:3.8. Antenna thick, distinctly longer than body length, penultimate flagellomere 1.6× longer than wide.   
 Mesosoma. Length:width:height = 32.8:23.0:24.0. Disc of mesonotum shiny, with relatively strong, fine punctures, except tending to be polished medial-apically. Scutellar sulcus straight, broad, deeply crenulated. Scutellum highly shiny and polished, scattered with several small punctures laterally. Propodeum dull, with groove-like depression above orifice in middle defined by a small U-shaped areolation at bottom, anterio-laterally strongly coarsely punctate. Costulae absent or indistinct but posterior forked carinae obviously present, posterior lateral fields distinctly declivous, shiny and nearly polished. Mesopleuron highly polished, anterior part closely strongly punctate.   
 Legs. Hind coxa shiny without punctures. Spines on outer side of third tibia scattered. Inner spur of hind tibia 2/5 length of hind basitarsus, outer spur less than 1/3. Basitarsus of hind leg nearly as long as tarsomeres 2–4 combined.   
 Wings. Pterostigma 2.9× as long as its widest part. Vein 1-R1 1.3× longer than pterostigma, nearly closing marginal cell. Vein r arising from apex of pterostigma, weakly inclined outwards, evenly curved, weakly shorter than width of pterostigma, r weakly longer than 2-SR, angled at junction, 2-M half length of 2-SR and slightly longer than 1-SR but shorter than 2-SR+M, m-cu as long as width of pterostigma. First discal cell of fore wing 1.3× wider than high. Second submarginal cell of hind wing 2.0× wider than high (9.0:4.5). Vein cu-a straight, perpendicular to 1-1A.   
 Metasoma. Metasoma 1.1× longer than mesosoma. T1 more or less wedge-shaped, horizontal part 1.6× as long as wide across the hump, basal one third concave, shiny and nearly polished entirely (except several indistinct punctures along apical sides). T2 weakly transverse, 2.4× wider than long in the middle, strongly curved into T3 apically. T3 1.5× longer than T2. Tergites posterior to T1 polished, shiny, and sparsely pubescent. Hypopygium large, not longer than apex of mesosoma. Ovipositor sheath weakly longer than hind tibia (31.8.0:30.0), thin and nearly parallel-sided, ovipositor curved throughout, with a short apical attenuation.   
 Colour. Black, T1 and T2 reddish yellow to yellow. Tegula brown. Palpi and spurs pale yellowish. Flagellum brown, pedicel and scape yellow. Ovipositor sheath brown. Labrum and mandible bright yellow. Legs bright yellow entirely (including coxae). Wing membrane hyaline, pterostigma brown, alar veins brownish.   
 Variation. Body length 2.2–2.4 mm, fore wing length 2.5–2.6 mm. Tergites posterior to T2 yellowish brown (specimen from Mt. Gutian) to blackish brown.   
 Male. Body length 2.1–2.4 mm, fore wing length 2.5–2.7 mm. Similar to female, except: penultimate flagellomere 2.0× longer than wide and tergites posterior to T2 more or less yellowish or brown with whitish hind.   
 Material examined. Holotype: ♀, Kending National Forest Park, Taiwan, 2011.V.31, Tang Pu, No. 201104941. Paratypes: 21♂♂, ditto, Nos. 201104934, 201104939, 201104932, 201104931, 201104930, 201104912, 201104914, 201104915, 201104920, 201104921, 201104923, 201104925, 201104933, 201104936, 201104905, 201104907, 201104909, 201104911, 201104926, 201104927, 201104938; 2♀♀ 1♂, Mt.Wugong, Gaoxiong, Taiwan, 2011.VI.15, Tang Pu, Nos. 201104845, 201104836, 201104829 (♂); 1♂, Duonalindao, Taiwan, 2011.VI.13, No. 201104979; 1♀, Mt. Gutian, Zhejiang, 2005.VII.3, Wu Qiong, No. 200616975.   
 Distribution. China (Taiwan, Zhejiang).   
 Etymology. The specific name “ ambultor ” derives from the Latin “amb-” and species-group “ultor”, referring to the transitional state between two species-groups ater and ultor.   
 Remarks. This species is similar to D. latitergita Liu & Chen, sp. nov., but differs in the following: penultimate flagellomere 1.7× longer than wide (cubic in latter); pterostigma relatively small, 2.8× as long as its widest part (very large, 2.3× in latter); and tegula yellow (black in latter).
