Description. Female. Length 2.8–5.2 mm ( Fig. 18A View FIGURE 18 ). Color. Head and mesosoma iridescent blue-green. Scape yellow to partially brown with iridescence; pedicel and anellus brown. Femora dark brown with iridescence on basal two-thirds, fading to yellow on distal third. Gaster dark brown with strong green-blue iridescence. Head ( Fig. 18B View FIGURE 18 ). HW:HH = 1.1–1.4; IOD:EH = 1.8–2.1; MS:EH = 1.0–1.5. Labrum with 4 digits. FL:HH = 1.2–1.5; F2L:F2W = 1.2–1.5, F2L:F3L = 1.0–1.4 ( Fig. 18D View FIGURE 18 ). Mesosoma ( Fig. 18C, F View FIGURE 18 ). ML:MH = 1.0–1.2. Axilla rugose; axillular sulcus weak and foveate; axillula areolate to areolate-reticulate. Propodeal disc areolate ( Fig. 18G View FIGURE 18 ); callus areolate-reticulate. Propleuron rugose-reticulate. Upper mesepimeron reticulate. HCL:HCW = 1.4–1.8; HFL:HFW = 4.8–6.3. FWL:FWW = 2.2–2.6, FWL:ML = 2.1–2.4. Metasoma. PTL:PTW = 1.1–1.9, PTL:HCL = 0.6–1.2, reticulate, ventral sulcus absent. Ovipositor with second (dorsal) valvula with 6 or 7 annuli that are narrowly separated dorsally, the carinae coalescing.

Male. Length 3.6–4.0 mm. HW:HH = 1.2–1.3. FL:HH = 1.8–2.0, F2L:F2W = 1.6–2.0 ( Fig. 18E View FIGURE 18 ). Femora dark brown medially, tips yellow. PTL:PTW = 4.2–6.5, PTL:HCL = 2.0–2.2.
