Figs 23, 24, 108, 179, 219  
 Description. Holotype FEMALE. Fore wing 13.6 mm.   
 Head. Ventral tooth of mandible about as long as dorsal tooth. Clypeus apical area delimited medially by brief emargination or incision; clypeal margin with two weak teeth. Antenna beyond flagellomere VI missing; white band starting at flagellomere IV.   
 Mesosoma. Mesopleuron glabrous, weakly and only partially striate. Subalar prominence large, suboval, not keeled. Sulcus between sternaulus and scrobe weak, inconspicuous. Posterior transverse carina of mesosternum absent. Lower metapleuron faintly and incompletely striate-rugulose. Propodeum: area in front of anterior transverse carina polished, smooth, medially without longitudinal ridges. Propodeal apophyses present as very weak and small scale-shaped structures. Posterior transverse carina absent. Propodeum behind anterior transverse carinae densely and regularly finely arcuate-striate, changing to oblique on area between apophyses and apex. Fore wing in Fig. 179; vein 3-Cu 1.48 length of 4-Cu. Hind wing in Fig. 219.   
 Metasoma. Postpetiole dorsally at level of spiracles flat; dorsolateral carina and median dorsal carinae absent; petiolar spiracles in dorsal view not prominent. Ovipositor 1.18 length of hind tibia. Apex of lower valve with 13 teeth.   
 Color. Black and yellowish to reddish brown, with pale yellow marks. Lateral pattern as in Fig. 23. Orbital band complete, very narrow at malar space only; width on supra-antennal area and temple about 0.3 of interocular distance; on temples, yellow stripe margin projecting shortly but distinctly towards center (Fig. 108); gena entirely yellow. Clypeus, including clypeal sulcus, and supraclypeal area entirely yellow. Mesosoma dorsally from pronotum to metanotum black, otherwise orange brown; yellow marks as follows. Pronotum collar entirely yellow, pronotum laterally on dorsal margin with large elongate yellow spot. Propleuron yellowish brown with large subapical dark brown area on each hemisternite. Mesoscutum centrally, at level of tegula, with distinct, anteriorly acuminate yellow spot between notaulus. Axillar carina, scutellum and postscutellum yellow. Propodeum as in Figs 23 & 24, with very weak medio-longitudinal pale yellow stripe. Fore and mid femora yellowish light brown. Hind femur orange brown. All tibiae opaque yellowish, hind tibia darker basally. Fore and mid t1 yellowish brown; apex of mid t1 and fore and mid t2–5 dark brown. Hind tarsus pale yellow. Metasoma dorsally black, except as follows. Petiole basally yellowish, apically reddish brown, changing to black at postpetiole, which apically has a large semicircular yellow spot from side to side. T2–7 apical margin with somewhat narrow yellow stripe. T8 without yellow visible above.   
 Morphological variation. Fore wing 8.0– 15.3 mm. Ovipositor 1.18–1.28 length of hind tibia. Antenna with 27–28 flagellomeres, white band starting at flagellomere IV, with 6–7 articles. Mesoscutum: central yellow spot absent on specimens from Manaus and Obidos (northern Brazil). Propodeum color highly variable, from entirely yellowish or yellowish with black marks to entirely black; medio-longitudinal stripe from weak, pale yellow, to intensely yellow. Mesopleuron may show distinct, but delicate, striation. Lower metapleuron distinctly, regularly finely striate on largest specimen. Meso- and metapleuron sometimes with irregular pale yellow spots. Mid femur light to dark brown on specimens from Brazil. Hind femur on dorsal half dark brown on most specimens; four females with hind femur almost entirely yellowish brown. On paratype from Barquisimeto (Venezuela) propodeum with yellow and black marks near spiracle, medio-longitudinal yellow stripe conspicuous. All specimens from Brazil more reddish than others.   
MALE. Very similar to female, except as follows. Microsculpturing tends to disappear, giving place to polished areas, on smallest specimens. Antenna with white band starting at apex of flagellomere VII, rarely VIII; in one case VIII entirely brown and IX entirely white; with 9–10 fully white flagellomeres. On the smallest specimen, from Quincemil (Peru), orbital band interrupted between 3–4 h; mesonotum centrally without yellow spot; and hind femur black, except basal end yellowish brown.  
 Comments. Similar to D. varipes, from which it can be isolated by having orbital band complete and projecting towards center (vs. broadly interrupted and not projected; compare Figs 108 vs. 112); white band of antenna starting at apical 0.3 of flagellomere IV in all studied females, while in D. varipes it starts at the apex of flagellomere V in nearly all females; pronotum laterally with black reaching ventral angle (vs. changing to reddish brown); central yellow spot of mesoscutum anteriorly acuminate (vs. round or nearly so); speculum and carinal triangle yellowish (vs. dark orange as most of mesonotum); propodeum medio-longitudinally with a faint to distinct yellowish mark (vs. rarely present or, if so, propodeum also with dark marks); dorsal yellow spot of mesoscutum somewhat elongate, and pointed anteriorly (vs. usually rounded); apical yellow spot of T1 large, reaching and advancing a little over lateral margins (vs. not reaching lateral margins); T1 basally sometimes widely or mostly orange (vs. black extending from yellow spot to base of T1 or almost so); T2 apex entirely covered by a yellow stripe of uniform width (vs. yellow stripe not reaching lateral margins); hind t5 mostly or entirely yellow (vs. entirely dark brown). The known distribution is also distinct, the current species occurring in Peru, northern Brazil, Venezuela, and Panama, while D. varipes is known from southeastern Brazil to Argentina.   
 Males of these two species can be generally separated by the same features which characterize the respective females, and by the white band of antenna starting at apex of flagellomere VII or VIII in males of D. archisius (vs. starting at flagellomere IX). As in D. varipes, the highly variable presence of black on the hind femur, for both sexes, seems to be of little or no taxonomic relevance.
