DIAGNOSIS. Female (length about 2.1-2.5mm): antenna (Figs 1723-1725) with scape dark brown; scutellum in proximal half relatively dull coppery purple with some weak violet reflections laterally, in apical half contrasting shiny metallic blue-green; fore tibia more or less completely pale orange, mid and hind tibiae pale orange in apical half; eye separated from occipital margin by much less than diameter of facet, occipital margin sharp at nearest point to eye; vertex with a broadly oval, shiny bottomed depression adjacent to eye, slightly smaller than diameter of posterior ocellus and a little behind it; frontovertex (Fig. 1732) with shallow, small, inconspicuous piliferous punctures; antenna (Figs 1723-1725) with pedicel a little more than 2X as long as broad, F1 subequal in length and width to pedicel and about 1.5-2X as long as broad; F6 subquadrate, not more than 1.2X as long as broad; flagellum very slightly shorter than head width; fore wing with venation and distribution of setae as in Figs 1730, 1731; posterolateral angle of propodeum (Fig. 1726) with a short, broadly truncate tooth above hind coxa, area between tooth and spiracle convex not depressed; gaster very slightly shorter than thorax; last tergite about 0.75X as long as mid tibia; hypopygium (Fig. 1727) with depth of posterior invagination about 0.5-0.8X mid tibial spur; ovipositor (Fig,. 1728) about 1.7-1.9X as long as syntergum and about 3.6-3.9X as long as gonostylus. Male (length about 1.8mm): antenna (Fig. 1729) with F1 at most about 2X as long as broad, as wide as pedicel, with at most 25 longitudinal sensilla, each of which is about 0.25X as long as segment; aedeagus (Fig 1722) with pores separated from apex by about 2X their own diameters, apex acute; setae on each side of phallobase relatively close, separated by not more than 1.5X the diameter of sockets.
