(Figs 44, 52, 60, 71, 75, 88, 95, 126)  
 Description. Female. Fore wing 7.4 mm. Head (Figs 75, 88): Antenna with 28–32 flagellomeres. Clypeus smooth, sparsely punctate towards apex, markedly convex, most prominent ventrally, CWH 1.53; MWC 0.58, MLW 1.82, MWW 0.55; malar space moderately long, MSM 1.27; supra-antennal area with faint, median, longitudinal carina; minimum distance from eye margin to occipital carina laterally approximately same width of mandible base.   
 Mesosoma (Fig. 95). Pronotum lateral portion next to collar inconspicuously strigate-rugose, next to mesopleuron inconspicuously corrugated, epomia faint; notaulus inconspicuously impressed, uniformly sculptured with mesoscutum, reaching about middle of mesoscutum (Fig. 44); mesopleuron dorsal half medially faintly strigulate-rugulose, ventral half without distinct ridges or rugae, epicnemial carina restricted to ventral 0.8 of mesopleuron, posteriorly inconspicuously, densely corrugated; mesopleural groove markedly, sparsely corrugated; sternaulus entirely moderately corrugated; postpectal carina medially slightly to distinctly bent; metapleuron, subapical fovea shallow, subcircular (Fig. 52); pleural carina moderately stout; propodeum anterior area short, PLL 0.44, anterior transverse carina distinct, complete, medially distinctly arched forwards, posterior area densely strigulate-rugulose, with ridges not forming distinct pattern, spiracle distinctly elliptic, SWL 2.00, propodeal apophyses short, conical, AHD 1.00. Legs (Figs 60, 71): Hind t4 posterior lobe about 0.67 × as long as anterior lobe (Fig. 71). Fore wing vein (Rs+M)b slightly sinuous, limit with crossvein 1m-cu indistinct, ramellus absent; vein Rs&1M posteriorly slightly curved; crossvein 1cu-a uniformly slightly convex, arising distinctly apicad vein Rs&1M, by about 0.1 × 1cu-a length, angle with vein M+Cu about 90 degrees; vein 2Cua moderately shorter than crossvein 2cu-a, FWC 0.75; areolet small, APH 0.79; vein 2Ma approximately as long as vein 2Mb; vein 2Mb tubular; crossvein 2m-cu with bulla short, about 0.2 × as long as vein length or shorter; vein 2Rsb sinuous. Hind wing vein 2-1A long, reaching about 0.8 × the distance to wing margin, HWC 2.06.   
 Metasoma (Fig. 95). T1 petiole basal half smooth towards base, apical half, postpetiole coriarious-punctulate, except pospetiole apical parts centrally smooth, sparsely punctulate, spiracle at about basal 0.6, not prominent, T1LW 2.90, T1WW 2.61, T1GL 0.32; T2 moderately short, apically robust, T2T1L 0.75, thyridium distinctly longer than wide, T2LW 1.03, T2WW 1.90. Ovipositor slightly but uniformly downcurved, OST 0.61, dorsal valve with nodus faint, notch present; ventral valve tip with inconspicuous serrations restricted to very tip.   
 Color. Head, mesosoma, legs and metasoma black. Head: Dorsal portion of flagellomeres 5–9 and mouth parts, except mandible, white; mandible blackish, dorsal and ventral margins and apex before teeth lightest, often whitish (242, 228, 204). Mesosoma: Propodeal apophyses white. Legs: Coxae and trochanters apical margin, fore tibia anteriorly and posteriorly, mid tibia posteriorly and basal 0.2 ventrally, and hind tibia basal 0.1 dorsally with whitish mark; fore femur ventrally whitish towards apex; fore t1 pale yellow (221, 190, 117); mid tarsomeres, hind femur, tibia and tarsomeres dark brown (109, 083, 060). Wings: Hyaline. Metasoma: T1 apical margin with central semicircular mark light brown; apical margin of T2–3 whitish; sternites medially white; T2–8 basally black, brownish towards apex; ovipositor sheath dark brown, except basal 0.6 ventrally whitish; ovipositor brown (174, 111, 057).   
 Male. Unknown.   
 Variability. Body size highly variable, with the fore wing length about 6.10 to 8.50 mm. Color: Flagellomeres 4 apical parts and 10 basal parts sometimes white; mandible dorsal margin occasionally slightly whitish; extension and brightness of lightest marks on legs variable; T1 apical margin semicircular mark occasionally taking the entire margin.   
 Comments. Included in the D. soror species group (see item Species Delimitation). It is remarkable that the examined specimens have extreme body size variation as cited under “Variability,” but their identical morphologic features and body coloration strongly support all individuals indeed as a single species. The largest specimens of D. dnopheror can resemble specimens of D. dialeucor because of their similar general morphology and black coloration, but can be recognizable in having the clypeus entirely black (vs. with a central white spot), hind t4 lobes of unequal size, posterior lobe about 0.67 × as long as anterior lobe (vs. lobes of approximately equal size, posterior lobe about 0.95 × as long as anterior lobe), T1 spiracle not prominent (vs. inconspicuously prominent), and apical margin of coxae distinctly whitish (vs. slightly whitish). Its general black coloration can also make it resemble D. palaior, but it can be easily identifiable by having a fainter general sculpturing and strigation on some body regions, such as the pronotum lateral portion next to collar inconspicuously strigate-rugose, and next to mesopleuron inconspicuously corrugated (vs. distinctly strigate to rugose), epomia delicate (vs. moderately stout), mesopleuron dorsal half medially faintly strigulate-rugulose, ventral half without distinct ridges or rugae (vs. dorsal half medially strigulate, ventral half posteriorly strigate with ridges taking mesopleural groove), and sternaulus entirely moderately corrugated (vs. entirely markedly corrugated). However, the coloration of D. dnopheror also differs from that of D. palaior in having the wings hyaline (vs. with uniform yellowish tint) and coxae apical margin whitish (vs. coxae entirely black).   
 Etymology. From the Greek word dnopheron, meaning “dark,” in reference to the body almost entirely black in this species.
