Size

6.0–8.8 mm (0.24–0.35 in)^[5]

Face

densely Dusted in yellow or grey, with a slightly shining tubercle. The oral margin is rounded at the bottom.

Legs

Pale with darker markings, including a posterior stripe on the fore femur and the basal two-thirds of the mid-femur. Darker areas also appear on mid tarsomeres 4 and 5, the basal three-quarters of the hind femur, the apical three-quarters of the hind tibia, and the hind tarsus. A tuft of 2-3 long, wavy, tightly pressed white hairs adorns the posterior of the fore femur, complemented by black pile elsewhere (see image). The fore tibia broadens from base to tip and has a pointed posterior angle. The first fore tarsomere (T1) is narrower than the tibia's apex, narrowing on the basal third and remaining parallel-sided on the apical two-thirds. There is a shallow groove below. The other fore tarsomeres are slightly narrower than T1. On the mid-femur, up to 13 short black setae (thick hairs) are present on the basal half, along with 4-6 long downward black setae. The mid-tibia features a strong ventral black pile on its basal half.

Thorax

The **Scutum and Scutellum** shine in black, lightly dusted on the sides.

Wings

Brown-tinted and entirely microtrichose, (covered with tiny hairs). The halter knob is brown or yellow.

Abdomen

is parallel-sided, displaying yellow or orange spots on the tergites, sometimes with faint silvery dusting. The second tergite features small, circular spots well separated from the front margin, while tergites 3 and 4 have spots that meet the anterior margins. Tergite 5 is entirely dark.^{[6][7][8][9][10][11]}
