Diagnosis: It belongs to the annulicornis species-group, and can be separated from other species within that group based on the combination of flagellomeres brown, coloration of mesosoma (propleuron, pronotum partially, small spot on upper corner of mesopleuron, and small marks centrally on anteromesoscutum orange-yellow, rest dark brown), and metacoxa brown.
Description: Female. Body length 2.0–2.1 mm. Fore wing length 2.2–2.3 mm. Head color: mostly dark brown to black; except for orange on most of frons and face, and yellow clypeus, labrum, mandibles, and spot on lower corner of gena near oral foramen. Flagellomere color: all flagellomere brown to black. Mesosoma color: mostly dark brown to black, with pronotum, propleura, anteromesoscutum, spot on mesopleura, and scutellar disc at least partially orange. Metasoma color (dorsally): mostly dark brown to black, except for yellow-orange anterior 0.4–0.6 of mediotergite 1. Coxae color: pale/pale/mostly or completely dark. Metatibia color: mostly pale, with posterior 0.1–0.2 dark. Metatarsus color: pale. Pterostigma color: mostly dark, but with anterior pale spot. Mediotergite 1 length/width at posterior margin 3.6–4.0 ×. Mediotergite 1 maximum width/width at posterior margin 2.5–2.6 ×. Mediotergite 2 width at posterior margin/length: 3.6–3.7 ×. Mediotergite 2 sculpture: Mostly with longitudinally striate sculpture (sometimes with small, smooth area centrally). Ovipositor sheaths length: 1.0 × as long as metatibia. Male. As female, but with coloration of some specimens slightly darker.
