Description. Ground color light brown to castaneous dorsally and light yellow to brownish yellow ventrally, with extensive areas of metallic green and black; a few ivory markings. Body length excluding hemelytral membranes about 7.5 mm.

Dorsum ofhead metallic green, rather flat before eyes, lateral jugal margins slightly reflexed. Width of head across eyes 2.05 mm, length from ocelli to apex 1.2 - 1.25 mm; interocular width 0.95 - 1.0 mm; distance across ocelli 0.7 mm. Ocelli about 0.1 mm in diameter. Basal part of first antennal segments pale, remainder of antennae black; length of segments 1 - 5 about 0.4 - 0.45, 1.0 - 1.1, 1.1 - 1.3, 1.6, 1.65 mm (fused 4 + 5 in holotype 2.5 mm long). Rostral segments 2 - 4 about 1.0, 1.0, 1.3 mm long; first segment and base of second pale, remainder of rostrum fuscous.

Anterior, posterior and posterolateral pronotal margins and humeri bordered in metallic green. Transverse, impunctate band behind cicatrices and edge of antero lateral margins cephalad of this band, light yellow. Anterolateral margins nearly straight. Pronotal width at humeri 4.6 mm, mesial length 1.9 mm.

Mesial spot at base of scutellum, another at apex, ivory; tongue more or lessmetallic green. Width of scutellum at base 3.0 mm, at distal end of frena 1.1 mm; mesial length 2.9 mm.

Exocorium and posterolateral angle of endocorium of each hemelytron metallic green; adjacent area of endocorium blackish, impunctate, with ivory spot; corial spots and spot on scutellar apex nearly in line. Distal margin of each corium concave, costal angle acute. Membranes of hemelytra heavily fumose, projecting well past apex of body; veins numerous, simple.

Exposed portion of connexiva yellowish, immaculate excepting lateral edge of segments at and near posterolateral angles dark; these angles protruding slightly.

Venter ofhead yellow. Thoracic venter metallic green, excluding dark evaporative areas, with yellow as follows: on prothorax a narrow border along anterior margin between eyes, narrow border along posterior margin, and broad lateral borders; on mesothorax lateral borders and posterolateral corners; on metathorax posterolateral corners; area bordering each supracoxal cleft. Coxae, trochanters and basal region of middle and hind femora yellow, remainder of legs dark brown to black. Abdominal venter yellow with sternites 2 - 4 (first three visible) black exclusive ofbroad borders laterally and sometimes a pair of spots near meson of sterniite 4; on remaining sternites sutures between them, pseudosutures, and mesial linemay be dark in part or whole. Basal plates convex proximally, quite concave distally, nearly reaching apex of abdomen ( Fig. 16). Only apex of paratergite 9 exposed. Spiracles present on para tergite 8.

Male unknown.
