Redescription. FEMALE. Body length 12 mm; fore wing length 9 mm. Clypeus in lateral view moderately convex, in frontal view as long as wide (Fig. 13). Mandible with dorsalmost tooth short and blunt. Pronotal carina strongly produced anteriorly at humeral angles, weakly produced medially. Scutellum and propodeum strongly convex. Metanotum nearly flat. Propodeum in lateral view evenly convex; median longitudinal furrow superficial; posterior face barely depressed medially in dorsal half, more or less distinctly depressed medially in ventral half. Metasomal tergum 1 in lateral view broadly convex dorsally in apical two thirds (Fig. 2), slenderer than that of E. blandus sumbanus . Metasomal tergum 2 in lateral view more or less evenly convex dorsally (Fig. 2), with weak preapical depression; sternum 2 hardly convex.

Body covered with dense silvery hairs; hairs on gena denser and longer than those in other parts of head. Head strongly punctured; clypeus with sparse minute punctures. Punctures on mesosoma slightly larger than those on head. Punctures on metasomal tergum 1 similar to but sparser than those on head; tergum 2 with sparse minute punctures. Body black, with following bright markings: labrum, tegula, parategula, ferruginous; clypeus entirely, large interantennal spot, ventral side of antennal scape, spot at posterolateral corner of pronotum, wide band along pronotal carina, paired lateral spots on dorsal part of propodeum, paired lateral spots and apical band on metasomal tergum 1, large lateral spots and wide apical band on tergum 2, yellow; apical bands on metasomal segments 3–6 (sometimes absent on segment 6) yellow to pale ferruginous. Wings fusco-hyaline; fore wing slightly darker along outer margin; pterostigma dark brown.

MALE. Body length 9–11 mm; fore wing length 7–8 mm. Clypeus in frontal view proportionally narrower (Fig. 14) than in female; mandible with dorsalmost tooth long and sharp. Clypeus entirely, band along outer margin of mandible, yellow; ventral part of antennal flagellomeres 8–10, apex of antenna, pale-ferruginous.

Distribution. Indonesia: Sumatra, Java, Sulawesi, *Lesser Sunda Islands (*Lombok, *Sumbawa).
