Diagnosis. Clypeus deeply indented, medially in form of wide semicircle, wider than antennal torulus; anterior carina of pronotal collar laterally curving towards pronotal lobe; IOC distinctly marked; POD subequal to OOD; in female cephalic punctation distinct, minimal beyond posterior ocellus, mesosoma with conspicuous punctation anteriorly, posteriorly shallow; in male punctation on head wide, scattered, mesosoma granulose with scattered pits; Gt 3 immaculate.

Description. Female. ( Figs 83–90 View FIGURES 83–90 ). Body length 10.97–11.10 mm; fore wing length 7.05–7.11 mm.

Median lobe of clypeus deeply indented, medially in form of wide semicircle, wider than antennal torulus ( Fig. 86 View FIGURES 83–90 ); IOC distinct, not followed by deep excavation on frons ( Fig. 86 View FIGURES 83–90 ); supra-orbital furrow oval, small; cephalic punctation distinct, minimal beyond posterior ocellus; POD subequal to OOD ( Fig. 84 View FIGURES 83–90 ); black with following parts variously coloured: scape yellow, pedicel and fu 1 brown with apex pale yellowish brown; pronotal collar and pronotal lobe pale yellow; axilla and scutellum dorso-medially pale yellow ( Fig. 87 View FIGURES 83–90 ); fore and mid femora black with apical pale yellow spot; fore and mid tibiae yellow with ventral brown streak; hind tibia brown with outer yellow streak; Gt 1 and Gt 3 immaculate; Gt 2 and Gt 4 with oblong maculae laterally; Gt 5 with median yellow band ( Fig. 90 View FIGURES 83–90 ).

Clypeus medially produced into sharp acute tooth ( Fig. 94 View FIGURES 91–96 ); IOC distinct; frons slightly declivous beyond IOC ( Fig. 93 View FIGURES 91–96 ); pronotum anteriorly without conspicuous rugae; black with following parts variously coloured: scape yellow, pedicel pale yellowish brown apically; pronotal collar, pronotal lobe, spot on axilla, continuous spots on scutellum ( Fig. 95 View FIGURES 91–96 ); fore and mid femora apically, fore and mid tibiae yellow with inner brown patch, hind tibia basal two-third yellow; Gt 1 with faint yellow macula; Gt 3 immaculate; Gt 2 and Gt 4 with large yellow maculae; maculae on Gt 5 almost meeting dorso-medially; Gt 6 with transverse yellow band basally ( Fig. 96 View FIGURES 91–96 ).

India: Karnataka (new state record), Kerala (new state record), Meghalaya (new state record), Sikkim (new state record), Tamil Nadu (new state record), Tripura (new state record), Uttar Pradesh (new state report), West Bengal. Elsewhere: China; Laos; Malaysia; Nepal; Pakistan; Philippines; Singapore; Taiwan; Thailand; Vietnam ( Pulawski 2021).

Taxonomic History. Leclercq (1956) recognized D. agilis (Smith) and D. ceylonicus Saussure ( orientalis + impetuosus + revelatus + infantulus + philippinensis + funestus ) as independent species based on differences in the shape of median lobe of clypeus in females. However, upon the examination of the types ( Leclercq 1972), frontal view; 86. Clypeus; 87. Mesosoma , dorsal view; 88. Mesosoma , lateral view; 89. Gt 1 & Gt 2, dorsal view; 90. Metasoma, lateral view.

he recognized D. agilis orientalis as a distinct subspecies of the nominotypic D. agilis ( agilis with the midlobe of clypeus deeply indented in semi-circle, without lateral teeth, while the female holotype of orientalis had clypeal lobe less deeply indented with sharp lateral teeth). The recognised subspecies has a more Oriental geographic distribution, while agilis shows an Australasian distribution. However, this subspecies recognition was not supported by the maculation on the terga and/or of mesosoma of female and the shape of clypeus in male. In fact the medio-apical lobe of clypeus in D. orientalis is produced into a sharp acute tooth, readily distinguishable from that of D. agilis (median lobe of clypeus produced, apical margin truncated), along with maculation on scutellum (in D. agilis scutellum black, in D. orientalis scutellum with large yellow macula) and metasoma (in D. agilis Gt 1 immaculate, in D. orientalis Gt 1 with faint macula) and distinctive yellow colouration of legs in D. orientalis (in D. agilis legs brown with limited yellow marking). It therefore seems judicious to raise D. orientalis to a valid species.
