Material examined: 1 ♀, INDIA: Meghalaya, Umiam, College of P.G. Studies, 07.ii.2023, Kennedy Ningthoujam ( NIM) .

Diagnosis: Frons fulvous with 2 pairs of frontal and orbital setae, ocellar seta vestigial, medial and lateral vertical setae and postocellar setae well developed; scape, pedicel and flagellomere slightly fuscous, arista plumose, combined length of pedicel plus flagellomere as long as the face; face fulvous without any markings, genal seta present, postocular setae black and prominent. Scutum with well developed chaetotaxy, fulvous with two pairs of short, brown vittae and prescutellar, conical patch; anepisternum with two lateral brown vittae extending from postpronotal lobe to base of the wing; scutellum yellow with six scutellar setae. Wing dark brown with base of pterostigma fulvous, conical hyaline indentation in cell r 1 and cell m, hyaline spots in cell r 4+5 and dm. Abdomen fulvous with lateral black/brown patches on tergites 1–6 with a pair of submedian spots on tergites 2–5, tergite 6 with a median brown patch. Oviscape dark brown (1.56 mm), eversible membrane slightly shorter than oviscape (1.41 mm) with spicules on distal end of eversible membrane dome shaped with 7–8 conical projections, aculeus (0.98 mm) shorter than eversible membrane, with a blunt apex and well developed preapical setae (2 elongate pairs and two short pairs); spermathecae brown, spherical with an apical projection.
