Female. Body color: body mostly dark except for some sternites which may be pale. Antenna color: scape, pedicel, and flagellum dark. Coxae color (pro-, meso-, metacoxa): pale, pale, dark. Femora color (pro-, meso-, metafemur): pale, pale, mostly pale but posterior 0.2 or less dark. Tibiae color (pro-, meso-, metatibia): pale, pale, mostly pale but with posterior 0.2 or less dark. Tegula and humeral complex color: both pale. Pterostigma color: dark. Fore wing veins color: mostly dark (a few veins may be unpigmented). Antenna length/body length: antenna about as long as body (head to apex of metasoma); if slightly shorter, at least extending beyond anterior 0.7 metasoma length. Body in lateral view: not distinctly flattened dorso–ventrally. Body length (head to apex of metasoma): 2.5–2.6 mm or 2.7–2.8 mm. Fore wing length: 2.5–2.6 mm or 2.7–2.8 mm. Ocular–ocellar line/posterior ocellus diameter: 2.0–2.2. Interocellar distance/posterior ocellus diameter: 1.7–1.9. Antennal flagellomerus 2 length/width: 2.6–2.8. Antennal flagellomerus 14 length/width: 1.0 or less. Length of flagellomerus 2/length of flagellomerus 14: 2.6–2.8. Tarsal claws: with single basal spine–like seta. Metafemur length/width: 3.0–3.1. Metatibia inner spur length/metabasitarsus length: 0.4–0.5. Anteromesoscutum: mostly with deep, dense punctures (separated by less than 2.0 × its maximum diameter). Mesoscutellar disc: with punctures near margins, central part mostly smooth. Number of pits in scutoscutellar sulcus: 9 or 10. Maximum height of mesoscutellum lunules/maximum height of lateral face of mesoscutellum: 0.4–0.5. Propodeum areola: completely defined by carinae, including transverse carina extending to spiracle. Propodeum background sculpture: mostly sculptured. Mediotergite 1 length/width at posterior margin: 2.3–2.5. Mediotergite 1 shape: more or less parallel–sided. Mediotergite 1 sculpture: mostly sculptured, excavated area centrally with transverse striation inside and/or a polished knob centrally on posterior margin of mediotergite. Mediotergite 2 width at posterior margin/length: 3.6–3.9. Mediotergite 2 sculpture: with some sculpture, mostly near posterior margin. Outer margin of hypopygium: with a medially folded, transparent, semi–desclerotized area; with 0–3 pleats visible. Ovipositor thickness: anterior width at most 2.0 × posterior width (beyond ovipositor constriction). Ovipositor sheaths length/metatibial length: 0.6–0.7. Length of fore wing veins r/2RS: 1.4–1.6. Length of fore wing veins 2RS/2M: 1.1–1.3. Length of fore wing veins 2M/(RS+M)b: 0.7–0.8. Pterostigma length/width: 2.6–3.0. Point of insertion of vein r in pterostigma: clearly before half way point length of pterostigma. Angle of vein r with fore wing anterior margin: clearly outwards, inclined towards fore wing apex. Shape of junction of veins r and 2RS in fore wing: distinctly but not strongly angled. Male. As in female.
