Diagnosis

Arista bare; scutum yellow to yellow-brown, without transverse band but centre with silver-grey pilosity and microtrichosity; postpronotum white; scutellum white; anatergite and katatergite completely white; legs completely yellow; wing, anterior apical band complete, touching discal band, in male area between posterior apical band and anterior apical band partially darker coloured, discal band not reaching posterior margin; abdomen shining brown with distinct yellow patches on most tergites.

Description

Head. Antennal segments yellow. Arista bare. Frons yellow to yellow-orange. Two frontals, placed parallel to medial eye margin; two orbitals, placed slightly convergent with anterior orbital located more medially. Face white. Occiput completely yellow in dorsal part, only faint pair of brownish patches; otherwise white.

Thorax. Scutum shining yellowish, along margins more yellow-brown, with dark pilosity; centre with silvery pilosity and microtrichosity, no transverse bands. Postpronotum white. Anepisternum pale yellow, with white band occupying posterodorsal part, its ventral margin reaching posteroventral corner; with pale pilosity; one anepisternal seta. Anatergite and katatergite white. Scutellum white. Subscutellum brown. Legs pale yellow.

Wing ( Figure 1B View Figure 1 ). Wing bands brown, well developed but with diffused margins. Basal part wing brownish coloured, subbasal irregular dark spots or streaks present, no distinct subbasal band. Anterior apical band covering cells r 1 and r 2+3 completely, area between anterior apical band and posterior apical band is partially darker coloured than rest of wing. Subapical band touching anterior apical band or almost so. Discal band and anterior apical band united at pterostigma. Discal band not reaching posterior wing margin, basally confluent with subbasal streaks and spots. R-M ratio 0.79–0.87.

Abdomen. Shining brown, tergites 1–2 pale yellow except lateral margins of tergite 2 brown, tergite 4 with posterior half yellow, in median part yellow band reaching anterior margin, tergite 5 broadly yellow in median part.

Female. As male except for following characters: mid and hind femur with darker apical patch anteriorly. Wing with distinctly separated anterior and posterior apical bands and subapical band. Posterior apical band touching anterior apical band only at base; subapical band isolated. Female terminalia, oviscape about as long as abdominal tergites, shining brown, with black pilosity. Aculeus ( Figure 3D View Figure 3 ) orange, flattened, about eight times as long as wide; aculeus tip ( Figure 4F View Figure 4 ) slightly narrowed, almost straight, pointed.

Body length. 3.50–4.30 mm; wing length 3.60–4.20 mm.
