Diagnosis.

Female. Body length 10.7–16.5 mm, fore wing 7.2–11.8 mm. Body largely black, following markings creamy yellow: broad band on inner and outer orbits, apical margin of clypeus broadly, without median constriction or separation, antenna 1-4 (5), posterior margin of pronotum, a large medio-posterior transverse mark of mesoscutum, tegula (sometimes wholly, sometimes in two or three spots); paired basolateral round spots on T 2, paired basal band on T 3, paired basal transverse large spots on T 4 (sometimes connected), on T 5 in variously twice constricted band, on GT 6 in a large basal mark and on S 6 spread completely over whole (Fig. 13 A – D ). Apical third of all femora, tibiae, spurs, tarsomere 1 and spines, and tarsomere 2 partly yellowish or brown, rest of tarsi pale or dark brown (Fig. 13 A ). Squamiform pubescence on metanotum, postnotum and propodeum brown yellow, on Tl- 3 coppery (Fig. 13 A, D ). Male. Body length 7.1–11.5 mm; fore wing 6.4–11.0 mm. In addition to spots seen in female, two lateral spots of clypeus; baso-lateral marks of T 3 (usually concealed) and a mark on T 7; hind tibia red, with obscure orange stripe on outer margin at base; apical margin beneath of coxae and a spot above of fore femur whitish yellow; apices of mid and hind femora and mid tibia on outer side slightly reddish; spur except apical part and spines pale (Fig. 14 A – D ). Squamiform pubescence on Tl- 3 coppery, but on metanotum, postnotum and propodeum white, with somewhat a yellow shine (Fig. 14 A, D ) ( Tsuneki 1989).
