Diagnosis. Body pale yellowish-brown. Frontal vitta yellow with narrow brown “Y” shaped stripe from anterior margin of frons to ocellar tubercle. First flagellomere ovate; arista apical with faint brown pubescence. Scutum dorsally with two white pruinescent stripes, separated by wide median brown stripe that narrows after transverse suture. Katatergite yellow. Femora yellowish-brown with inconspicuous pale brown distomedial ring.

Male. Body length 6.5–8.8 mm. Wing length 4.8–6.8 mm and width 1.4–1.9 mm. Yellowish-brown with partly yellow head and thorax ( Fig. 12 A).

Head. Moderately elongate in lateral view; dorsal length 1.2–1.6 mm and width 1.1–1.4 mm. Frontal vitta yellow, except for narrow brown “Y” shaped stripe from the anterior margin of frons to ocellar tubercle ( Fig. 12 C). Fronto-orbital plate yellow on anterior half, yellowish-brown on posterior half. Postocellar seta convergent, length 2.3–2.5 times transverse diameter of ocellar tubercle; inner vertical seta slightly convergent, equal to outer vertical seta; outer vertical seta divergent, subequal to postocellar seta. Genal seta hair-like, length 70% length of postocellar seta. Postgena slightly narrow posteriorly. Occiput height 2.5–2.7 times length ( Fig. 12 D). Antennal base brown. Antennae length 60–80% length of head. Scape yellow; 0.2 mm long. Pedicel paler than scape; 0.2 mm long; with outstanding dorso-apical seta; inner process of pedicel finger-like and relatively wide. First flagellomere oblong; length 1.5–1.7 times width. Arista apical with faint brown pubescence.

Thorax. Scutum dorsally with two white pruinescent stripes, separated by wide median brown stripe that narrows after transverse suture; pleuron partly yellow and velvety. Anterior notopleural seta absent. Posterior notopleural seta subequal to scutellar seta. Supra-alar seta subequal to postalar seta. Postalar seta subequal to scutellar seta. Dorsocentral seta length at least half length of scutellar seta. Scutellar seta length 70% length of scutellum. Proepisternum bare. Katepisternum brown with dorsal white pruinescent spot; katepisternal seta straight, black and equal to postalar seta. Katatergite yellow; length 1.8–2.0 times width.

Legs. Mid coxa with one lateral seta. Femora yellowish-brown with inconspicuous pale brown distomedial ring; mid femur anteriorly with three median setae.

Wing ( Fig. 12 E). Basicosta with dorsal inconspicuous seta. Halter whitish-yellow.

Abdomen. Yellowish-brown, dorsally with median yellow stripe from tergite 1 to tergite 4 or tergite 6. Syntergite 7+8 and epandrium shiny yellowish-brown.

Female. Similar to male, differs as follows: body length 6.2–8.0 mm ( Fig. 12 B). Wing length 6.1–6.8 mm and width 1.8–2.2 mm. Fore coxa without anterolateral seta. Oviscape yellowish-brown with apex yellow; length twice maximum width.
