Description. FEMALE. Fore wing 12.8 mm.

Head. Ventral tooth of mandible distinctly longer than dorsal tooth. Clypeus apical area delimited by smooth border; clypeal margin with one tooth. Antenna with 26 flagellomeres; white band starting at flagellomere V; 7 flagellomeres at least 50% white.

Mesosoma . Pronotum latero-ventrally with weak transverse strigation. Mesopleuron strigate, its surface and that of mesepimeron, carinal triangle, lower metapleuron and propodeum behind anterior transverse carina covered with dense white pilosity, hairs longest on propodeum. Subalar prominence suboval, anteriorly and posteriorly lanceolate, centrally rounded. Sternaulus deep, crenulated. Sulcus between sternaulus and scrobe absent. Posterior transverse carina of mesosternum absent. Lower metapleuron very finely strigate-rugulose. Propodeum: area in front of anterior transverse carina anteriorly glabrous, smooth, posterior 0.7 with sparse pilosity and shallow, pilosity-related foveolae, medially with two distinct, diverging ridges extending from carina towards anterior margin. Propodeal apophyses present as subtle scale-like widening of complete posterior transverse carina. Area between anterior and posterior transverse carinae densely, finely, longitudinally rugulose; area behind posterior carina with same sculpturing but approximately transverse. Fore wing in Fig. 189; vein 3-Cu 1.36 length of 4-Cu. Hind wing in Fig. 229.

Metasoma. Postpetiole medio-anteriorly flat, but laterally on each side with small and very weak concavity; dorsolateral and median dorsal carinae absent; petiolar spiracles in dorsal view not prominent. Ovipositor 1.11 length of hind tibia. Apex of lower valve with 13 teeth.

Color. Head, mesosoma and T1–2 main color black, all with pale yellow areas; T3–8 light orange. Lateral pattern as in Figs 79, 133. Orbital band briefly interrupted at malar space only; width on supra-antennal area, temple and dorsal part of gena about 0.2 width of interocular distance, covering most of ventral half of gena, almost reaching occipital carina, dorsally tapering ( Fig. 79). Mandible entirely black. Clypeus main area pale yellow; apical area and clypeal suture laterally, black; supraclypeal area, including parantennal impression, pale yellow. Mesosoma in Fig. 79, with few, small yellow areas laterally. Pronotum dorsally along anterior margin, except apex of lateral corner, with wide yellow stripe, widest just behind epomia; antero-laterally on dorsal margin with elongate yellow spot. Propleuron entirely black. Scutellum and postscutellum entirely yellow. Propodeum as in Figs 79–80, entirely black. Fore and mid coxae pale yellow, mesally brown; fore and mid trochanters pale yellow, fore trochanter antero-apically with small brown streak, mid trochanter anteriorly with wide longitudinal brown stripe; hind coxa, trochanter and trochantellus red (255,000,000); fore and mid femora mostly dark brown, except basal 0.1 pale orange, and mesally, but not basally, yellowish or reddish brown; hind femur orange, apex mesally darkened; fore and mid tibia yellow, mid tibia slightly darker than fore tibia; hind tibia deep yellow; fore and mid tarsi entirely dark brown; hind t1 from basally deep yellow to apically pale yellow, t2–4 pale yellow, t5 dark brown. Metasoma lateral pattern as in Fig. 79; dorsally T1 basally yellow, centrally black, apical margin with wide yellow stripe; T2 black, apical margin with wide yellow stripe; T3 basal margin narrowly black, T3 otherwise and entire T4–8 light orange.

Morphological variation. Fore wing 6.1–14.0 mm. Ovipositor 1.11–1.3 length of hind tibia. Antenna with 24 flagellomeres. Postpetiole on each side without weak lateral depression. Color: gena almost entirely yellow, except only very narrowly posteriorly; clypeal suture laterally yellow; axillar carina yellow, except posterior apex; hind femur progressively darker towards apex; fore and mid t1 at basal 0.8 yellowish brown; T1–2 dark brown instead of black or T2 red instead of black; T3 apical margin with very narrow yellow stripe.

MALE. Similar to female, except as follows. Antenna with 29–30 flagellomeres, white band with 8–9, starting at flagellomere IX; smallest specimen with 27 flagellomeres, white band with 5, starting at flagellomere X. Propodeum sculpturing progressively more fine and irregular with decrease in size of specimens; posterior transverse carina shaped as a “>”. Color ( Fig. 134) generally distinctly lighter than female; clypeal sulcus and malar area entirely yellow; hind coxa to femur light orange; fore and mid femora and tibiae yellow or deep yellow, without dark brown; fore t1–4 light yellow, sometimes (20%) brown; hind tibia apex and t1 at basal 0.2–0.8 dark brown, t1 apex and t2–4 entirely, white; metasoma color pattern as on female, but colors lighter, T1 with dark brown instead of black, T2 darkened only basally, T3 basally more extensively and diffusely darkened than on female. On males from Espírito Santo, Brazil, T1–T2 color pattern as on female, T3 dark brown, apical margin with yellow stripe.

Comments. Isolated from other species of the D. diversicolor complex by the combination of hind coxa without yellow dorsally and T2 main color black or at least darkest in relation to T3–8, also with a transverse yellow stripe apically. On the female, a somewhat transverse propodeum and its transverse carinae remarkably approximated are also characteristic ( Fig. 80). Males can be recognized by sharing the same overall color pattern of the female ( Fig. 134), particularly for the metasoma, as well as by showing the mid tarsus, and sometimes also the fore tarsus, mostly or fully brown or darkened.

The homotype of D. diversicolor Viereck in the AEIC differs from the holotype of D. grenadensis (as seen on photographs sent from the BMNH) by having T2 mostly black (vs. brown), the basis of the petiole yellow (vs. black), hind coxa black with a large yellow spot dorsally (vs. brown), T2 with complete and uniform apical yellow stripe (vs. interrupted medially), postscutellum centrally yellow (vs. entirely black),and mesepimeron black (vs. yellow).
