MALE—Length 11 mm.; entire body brilliant green, becoming bluish or purplish on abdomen apically; mandibles and labrum black to piceous; clypeus entirely green, shining, with deep, rather close and coarse punctures; supraclypeal area very finely and closely punctate, somewhat shining; face above antennae very closely and finely rugoso-punctate, punctures becoming more distinct on vertex; cheeks shining, sparsely and rather coarsely and deeply punctate below, becoming very minutely and closely punctate above; antennae entirely dark, 2nd segment of flagellum considerably longer than 1st, the following segments nearly twice as long as broad; lateral angles of pronotum broadly expanded, triangularly acute; scutum dull, densely and rather finely rugoso-punctate throughout; scutellum somewhat shining, punctures more coarse, deep and distinct, but quite close; pleura coarsely rugoso-punctate; dorsal area of propodeum subequal in breadth to metanotum, finely roughened, lateral faces closely and rather deeply punctate, posterior face shining, with shallow, scattered, irregular punctures; tegulae green anteriorly, becoming reddish-piceous posteriorly; wings lightly infuscated, veins and stigma brownish-testaceous; tarsi brownish-testaceous, legs otherwise largely green; abdominal terga deeply and closely punctate, basal tergum coarsely so, the successive more apical terga more finely so, terga 1 and 2 with short, apical, pale fimbriae, discal pubescence largely pale on the more basal terga, becoming intermixed with subappressed, fuscous hairs apically, the impressed apical margins more shining, with very fine and well separated punctures; apical margin of sternum 4 broadly incurved on each side of a median truncation, apical margin of sternum 6 nearly straight; gonostyli with a rounded, ventral, basal, inner lobe and a broadly truncate, subapical, flattened lobe, a rounded excavation between basal lobe and apex, both the rounded apex and the excavation bearing numerous elongate setae; volsellae slightly incised apically to form an obscure, outer cuspis, the digitus broad and bearing a short, acute spine on the inner side; penis valves excavated on dorsal surface toward base and on inner surface toward the acute apex.
