DIAGNOSIS. Female (length about 1.4-1.8mm): head generally metallic green or blue-green with violet areas especially in scrobal area; piliferous punctures conspicuous (Fig. 1412), but not contrasting, varying from slightly smaller to slightly larger than ocelli; lower face with setae slightly more dense than those on frontovertex and more conspicuous; thorax pale yellow to pale orange with pronotum, anterior part of mesoscutum and scutellum dark and metallic; hind femur pale orange; fore and mid tibiae yellow to pale orange, hind tibia pale orange with apex brown; all funicle segments (Fig. 1414) a little longer than broad, F6 subquadrate; apex of mandible oblique with 4 extremely short teeth (Fig. 1412); mesoscutum relatively dull with piliferous punctures shallow and indistinct, setae dark brown and conspicuous, sculpture shallow, fine, polygonally reticulate; scutellum with relatively deep, polygonally reticulate sculpture; fore leg with apical tarsomere (Fig. 1419) slightly longer than four basal tarsomeres; hind leg with apical tarsomere about as long as three basal tarsomeres; fore wing (Figs 1413, 1415) with postmarginal vein not reaching wing margin; hypopygium Fig, 1418); ovipositor Fig. 1416.
