Head. Head not depressed, transverse. Ocelli arranged in obtuse triangle. Frons more or less distinctly concave, without median keel and furrow. Eyes shortly and rather sparsely setose. Occipital carina dorsally complete, often fused below with hypostomal carina. Malar suture absent. Clypeus with short lower flange. Clypeal suture distinct laterally, rather shallow dorsally. Hypoclypeal depression medium size and rounded. Postgenal bridge narrow. Maxillary palpi rather long, 6-segmented, its sixth (apical) segment about as long as fifth segment; labial palpi 4-segmented, its third segment not shortened. Scape of antenna wide and short, without apical lobe or basal constriction, its ventral margin (lateral view) shorter than dorsal margin. First flagellomere simple, subcylindrical, weakly curved (in lateral view), usually weakly longer than second flagellomere.
Mesosoma. Mesosoma not or sometimes weakly depressed, medium-sized or weakly elongate. Neck of prothorax short, without pronope. Pronotum dorsally weakly convex; anterior flange distinctly curved up; pronotal carina rather distinct, situated in posterior third of pronotum. Propleural lobe long and wide. Mesonotum highly and perpendicularly or roundly elevated above pronotum. Median lobe of mesonotum usually without median longitudinal furrow, often with more or less distinct and rounded or sometimes pointed anterolateral corners. Notauli deep anteriorly and shallow posteriorly, complete, wide. Tegula weakly widened distally, convex along posterior margin. Prescutellar depression (scutellar sulcus) long, with several carinae. Scuto-scutellar (transscutal) suture distinct. Lateral longitudinal winglike flanges (on the level of prescutellar depression) usually low and rather fine. Scutellum (scutellar disc) weakly convex, with fine lateral carinae. Subalar depression rather deep and wide. Mesopleural pit (episternal scrobe) deep and elongate, fused with mesopleural suture. Metanotum with short and obtuse median tooth. Sternaulus (precoxal sulcus) rather deep, more or less narrow, long, weakly curved or almost straight. Prepectal carina distinct and complete, laterally continued up till sternaulus. Postpectal carina absent. Metapleural flange long, wide basally and rather narrow apically, almost rounded apically. Propodeum usually with areas delineated by carinae, areola present and more or less large; lateral propodeal tubercles wide and low; propodeal bridge absent. Propodeal spiracles rather small and round. Metapleural suture distinct. Metapleuron weakly convex.
Wings. Pterostigma of fore wing wide. Radial vein arising almost from or before middle of pterostigma. Radial cell usually not shortened. Both radiomedial veins always present. Second radiomedial cell medium-sized or rather long. Recurrent vein antefurcal or sometimes almost interstitial. Nervulus distinctly postfurcal. Discoidal cell petiolate anteriorly, petiole rather long. First medial abscissa curved or sinuate. Parallel vein distinctly curved basally. Brachial cell widely open postero-apically; brachial vein absent. Mediocubital vein weakly curved to anal vein. Transverse anal veins absent. Hind wing with 3 hamuli. Radial vein arising from costal vein rather far from basal vein. Radial vein strongly desclerotised, spectral. Radial cell subparallel-sided, without additional transverse vein. Medial cell narrow, weakly widened towards apex, 0.30–0.35 times as long as hind wing. Nervellus present. Submedial cell short. First abscissa of mediocubital vein 0.2–0.4 times as long as second abscissa. Recurrent vein long, distinctly oblique toward base of wing, nebulous. Hind wing of male usually (except D. atriventris) with stigmalike enlargement of the hecaboline type.
Legs. All tibiae rather slender; all femora with low anterodorsal protuberances. Fore tibia with several short and thick spines arranged in almost single vertical row. Middle tibia with several short and thick spines. Middle tarsal segments long. Hind coxa medium size, with distinct basoventral corner and tooth. Hind femur rather narrow, elongate-oval. Hind tibia with row of very dense white setae on inner distal edge. Hind tibial spurs rather short and slender, mainly glabrous, inner spur 0.25 times as long as hind basitarsus. Basitarsus of hind tarsus weakly thickened, rather short.
Metasoma. First tergite not petiolate, varied in length and width. Acrosternite of first segment usually short, but sometimes (two species) elongate, 0.2–0.4 times as long as first tergite. Dorsope of first tergite medium-sized, basolateral lobes absent; spiracular tubercles usually small or indistinct, situated in basal 0.3 of tergite; dorsal carinae distinct and complete. Second tergite with shallow or very shallow, wide subparallel or more or less divergent posteriorly longitudinal sublateral grooves separated subrectangular or trapezoid median area, but grooves often hardly developed. Suture between second and third tergites distinct, narrow, distinctly concave, without or with weak sublateral breaks. Third tergite with distinct or fine transverse furrow in basal 0.3–0.4. Second-fifth tergites with separate laterotergites. Hypopygium rather small, with distinct and pointed process medioposteriorly. Ovipositor apically with two obtuse and small dorsal nodes. Ovipositor sheath longer than metasoma. (from [1])
