Diagnosis: It belongs to the annulicornis species-group, and can be separated from other species within that group based on the combination of flagellomeres 4–8 white-yellow (occupying more than one third of antenna length), head mostly dark brown to black posteriorly, all coxae yellow, and T2 mostly striate.
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: central flagellomeres white-yellow, rest dark brown to black. Mesosoma color: entirely orange to yellow-orange. Metasoma color (dorsally): entirely orange to yellow-orange. Coxae color: all pale. Metatibia color: pale. Metatarsus color: pale. Pterostigma color: mostly dark, but with anterior pale spot. Mediotergite 1 length/width at posterior margin 4.6–5.0 ×. Mediotergite 1 maximum width/width at posterior margin 2.7–2.8 ×. Mediotergite 2 width at posterior margin/length: 3.2–3.3 ×. Mediotergite 2 sculpture: Mostly with longitudinally striate sculpture (sometimes with small, smooth area centrally). Ovipositor sheaths length: 0.8 × as long as metatibia. Male. As female, but with all flagellomeres brown.
Molecular data: Sequences in BOLD: 4, barcode compliant sequences: 4.
