Length

7.9–10.1 mm (0.31–0.40 in)

The face is strongly protruding downward, with the anterior oral margin extending well beyond the tubercle. The face is powdery yellow except for the shining black tubercle. (see Figure 1 and general anatomy) The legs are dark, but with short tip of femora and connection of the tibiae pale. The first two tarsomeres of the foreleg are very pale. The first front tarsomere (T1, see general anatomy) is nearly triangular, about 2.5 times as wide as the tip of the tibia, and slightly longer than wide. The second front tarsomere (T2) is nearly rectangular, three-quarters as wide as the first tarsomere, and one-quarter as long. The remaining fore tarsomeres are unmodified. The fore tibia has several fine, wavy setae (hairs) on the outer half of the bottom surface, with the longest setae being approximately three times the tibial width. The middle tibia has sparse, wavy, posterodorsal, and posterior pile (hairs) on the outer half, with the longest pile being about four times as long as the tibial diameter.(Figure 2) The first tarsomere (T1) of the hind leg is strongly swollen. The rest of the legs are unchanged. The entire thorax is strongly yellow or grey powdery, with dense thoracic pile, half pale and half dark. The halter is yellow, and the wing is completely microtrichose (microscopic hairs). The abdomen is narrowly oval, with spots of tergites 2-4 being yellow, longer than wide, and separated from the anterior and lateral margins of the tergites. The female has small yellow spots on tergite 5 ( see figure 1 bottom) ^[9]
