Vertex without lateral tubercles opposite posterior ocelli. Eye 1.15–1.20 × as high as broad. Malar space 0.25–0.30 × height of eye, 0.50–0.55 × basal width of mandible. Face width 0.85 × height of eye and 1.1–1.2 × height of face and clypeus combined. Clypeus convex, without lower flange. Hypoclypeal depression width 0.6–0.7 × distance from edge of depression to eye, 0.35 × width of face. Length of maxillary palpi about 1.5 × head height (without mandible). Head below eyes (front view) distinctly and roundly narrowed.
Antennae filiform, more than 30-segmented (apical segments missing). Scape 1.3 × longer than its maximum width, 2.4 × longer than pedicel. First flagellar segment 2.6 × longer than maximum width, almost as long as second segment. Second segment 4.5 × longer than wide. Submedian segments 2.7 × longer than its width.
Mesosoma. Length 2.35–2.40 × its height. Pronotal neck without pronotal carina. Median lobe of mesoscutum with very shallow median furrow. Notauli deep anteriorly and shallow posteriorly, fused submedially and following as single wide and shallow furrow towards posterior margin of mesoscutum, densely and coarsely crenulate and almost smooth between crenulae. Prescutellar depression deep, with three carinae and fine rugulosity between carinae, medially 0.25–0.30 × as long as scutellum. Scutellum with fine lateral carinae. Metanotum with two short or very short and subparallel carinae and one distinct and short median carinae (dorsal view); with very short wide and subround metanotal tooth (lateral view). Sternaulus rather shallow, weakly curved, sometimes medially finely crenulate, mostly or sometimes entirely smooth. Metapleural flange without pubescence along posterior margin.
Wings. Fore wing 3.1–3.5 × longer than its maximum width. Pterostigma 4.3 × longer than width. Metacarp 0.9 × as long as pterostigma. Second radial abscissa 1.3–1.4 × longer than first abscissa, 0.16–0.18 × as long as the straight third abscissa, 0.45–0.50 × as long as first radiomedial vein. Second radiomedial cell 1.7–1.8 × longer than its maximum width, 0.6–0.7 × as long as the rather narrow brachial cell. First medial abscissa distinctly sinuate. Mediocubital vein almost straight. Recurrent vein postfurcal. Nervulus almost perpendicular to mediocubital vein; distance from nervulus to basal vein 1.6 × nervulus length. Brachial cell rather narrow, long, widened medially, not narrowed apically. Hind wing 4.5–4.8 × longer than maximum width. First abscissa of mediocubital vein 0.40–0.45 × as long as second abscissa. Second mediocubital abscissa thick in basal half and with small submedian prominence, without additional oblique vein. Medial cell with weak constriction submedially, 8.0–8.3 × longer than wide, 0.45 × as long as wing. Recurrent vein straight, interstitial or weakly postfurcal, unsclerotized, but pigmented.
Legs. Fore tibia with six thick spines arranged in single row. Hind coxa rather wide, 1.5 × longer than wide. Hind femur 3.3 × longer than maximum width. Hind tibia dorsally with seven distinct spines arranged in single row. Hind tarsus about as long as hind tibia. Hind basitarsus thickened, 0.7 × as long as second-fifth segments combined (without pretarsus). Second segment of hind tarsus 0.45 × as long as basitarsus, 1.4 × longer than fifth segment (without pretarsus).
Metasoma 1.1 × longer than head and mesosoma combined. First tergite with small dorsope, with small or very small spiracular tubercles in basal 0.3, tergite weakly and linearly widened from base to apex. Acrosternite of first segment about 0.3 × as long as tergite. Maximum width of first tergite 1.7–1.8 × its minimum width; length 1.8–2.0 × its apical width, 1.6–1.8 × length of propodeum. Second tergite with distinct lateral and divergent posteriorly carinae. Median length of tergite 0.8–0.9 × its basal width, 1.7–2.0 × length of third tergite. Second suture shallow and narrow, evenly curved, without lateral bends. Laterotergites separated on second and third tergites. Ovipositor sheath 0.5 × as long as body, almost as long as metasoma, 1.5 × longer than mesosoma, 0.70–0.75 × as long as fore wing.
Sculpture and pubescence. Vertex very densely, distinctly and finely granulate; frons almost entirely curvedly transversely striate, densely granulate laterally. Face entirely coarsely and densely transversely striate; temple densely and very finely granulate in upper half and smooth or almost smooth in lower half. Mesoscutum very densely and small areolate-granulate, rugose in narrow medioposterior half. Scutellum densely and finely granulate. Mesopleuron mostly smooth, densely and finely or very finely granulate below and posteriorly. Propodeum with basolateral areas weakly or sometimes distinctly delineated by carinae, entirely finely coriaceous or very finely punctate to smooth in anterior half basolateral areas, remaining propodeum densely rugosereticulate. Hind coxae entirely or mostly smooth, sometimes only finely reticulate-granulate dorsolaterally. Hind femur densely and finely granulate-coriaceous, almost smooth below. First tergite densely undulately striate with rugosity, with two distinct and convergent dorsal carinae in basal 0.25. Second tergite entirely, densely and regularly longitudinally striate and with very fine reticulation between striae; third tergite densely striate with fine reticulation in basal 0.4, smooth on rest part. Remainder tergites smooth. Vertex entirely with rather dense, short and erect yellow setae. Mesoscutum entirely with very dense, short and erect white setae. Hind tibiae dorsally with rather short, dense and semi-erect setae, its length 0.3–0.6 × maximum width of tibia.
Colour. Body yellow or brownish yellow, mesoscutum infuscate. Antenna dark brown to black, three basal segments yellow to light reddish brown. Palpi pale yellow. Legs brownish yellow, hind tibia and tarsus yellow; all tibiae basally pale yellow. Ovipositor sheath brown to black, light brown basally. Fore wing faintly infuscate. Pterostigma brown, yellow in basal 0.3, pale yellow apically.
Male unknown.
Distribution. Madagascar.
Comparative diagnosis. This species belongs to the morphological group with short second metasomal tergite and very similar to D. ferrugineus (Granger); the differences between these species are showed in the key below.
Remark. Male represented in the original description as paratype of D. rubrotestaceus (Granger) actually belongs to D. ferrugineus (Granger).
