Description. Female: Total body length 9.40 mm; forewing length 6.48 mm. Head length 2.93 mm, width 1.87 mm. Clypeus beginning below lower tangent of compound eyes. Malar space 45% compound eye length (malar length 0.73 mm; compound eye length 1.63 mm). Upper interorbital distance 0.87 mm; lower interorbital distance 0.63 mm. Upper portion of pronotum medially depressed, not elongate, medially less than 0.25 times ocellar diameter in length; ventral portion of preepisternal sulcus distinctly broad dorsally at junction of scrobal sulcus and upper portion of preepisternal sulcus; intertegular distance 1.60 mm; mesoscutellum weakly convex, not bigibbous. Basal vein distad cu-a by three times vein width; 1rs-m distad 1m-cu by twice vein width; 2rs-m distad 2m-cu by seven times vein width, 2rs-m straight; first submarginal cell longer than combined lengths of second and third submarginal cells; second submarginal cell not narrowed anteriorly, anterior border of second submarginal cell along Rs slightly longer than that of third submarginal cell; posterior border of third submarginal cell nearly three times longer than anterior border. Distal hamuli arranged 2-1-2. Inner metatibial spur with six branches (not including apical portion of rachis).
Clypeus and supraclypeal area imbricate with weak punctures separated by 1–3 times a puncture width; face with small, contiguous punctures, more widely spaced in malar space; ocellocular area and vertex faintly imbricate with minute punctures separated by 1–5 times a puncture width; gena smooth with minute punctures separated by 1–6 times a puncture width; postgena imbricate and impunctate. Pronotum smooth with minute punctures separated by 1–2 times a puncture width; mesoscutum smooth with minute punctures separated by 1–3 times a puncture width on lateral thirds and along posterior border, medially punctures giving way to imbricate integument; mesoscutellum smooth with minute punctures separated by 1–3 times a puncture width; metanotum smooth with minute punctures separated by a puncture width. Preepisternum smooth to faintly imbricate with minute punctures separated by 2–3 times a puncture width; mesepisternum imbricate with minute punctures separated by 4–5 times a puncture width, punctures weak; metepisternum faintly imbricate. Propodeum strongly imbricate. Metasoma weakly imbricate.
Mandible dark brown except reddish at apex; labrum black; clypeal apex black, remainder blue-black; remainder of head blue-black. Antenna dark brown except ventral surfaces of flagellomeres III–X brown. Mesosoma blue-black, blue faint in most areas; tegula dark brown; propodeum dark metallic blue dorsally, blue-black laterally. Wing membranes weakly infumate; veins dark brown. Legs dark brown. Metasoma dark brown.
Pubescence gold to off-white except fuscous on mesoscutum, mesoscutellum, metanotum, outer surfaces of protibia and protarsus, outer surfaces of mesotibia and mesotarsus, inner surface of metatibia, metasomal T5–6, and S5–6; black on inner surfaces of tarsi and tibiae.
Male: As described for the female except as follows: Total body length 10.49 mm; forewing length 6.61 mm. Head length 2.93 mm, width 1.80 mm. Malar space 46% compound eye length (malar length 0.73 mm; compound eye length 1.60 mm). Upper interorbital distance 0.76 mm; lower interorbital distance 0.47 mm. First flagellomere about as long as pedicel, about as long as wide; second flagellomere four times length of first flagellomere (Fig. 15); ventral surfaces of second through eleventh flagellomeres densely covered in placoid sensilla, placoid fields disrupted by narrow mediolongitudinal line of fine, minute trichoid sensilla for lengths of flagellomeres V–VIII, at base and apex of flagellomere IV and basal half of flagellomere IX. Intertegular distance 1.37 mm; mesoscutellum bigibbous. Inner metatibial spur serrate. Apical margin of metasomal SIII entire; apical margin of SIV medioapically produced, with concave emargination between setose lobes (Fig. 16), with narrow medio-longitudinal furrow in apical half of disc (Fig. 16), furrow widening apically, basally bordered by short carinae; apical margin of SV minutely emarginate; apical margin of SVI emarginate; terminalia as depicted in figures 22 and 23.
Mandible, labrum, and clypeal apex off-white; small, faint off-white patch on malar space near mandible base. Ventral surface and base of scape pale yellow. Inner surface of protibia, profemur, and inner apex of mesofemur yellow.
Typical gender pilosity except postgena with numerous elongate, sinuate setae, such setae with short apical branches; inner surfaces of trochanters, mesofemur, metacoxa, metatrochanter, and metafemur with elongate, apically-plumose setae, similar setae on inner surface of metatibia except largely simple. Apical margin of metasomal SIII with fringe of moderate-length golden setae; SIV with medioapical pads of short golden setae bordering medial furrow (Fig. 16); SV laterally with diffuse pads of elongate, inwardly-curved setae (Fig. 16).
