The head is brown, with a dark gray powdery coating. The frons, clypeus, and occiput are blackish with gray powdery covering. The occiput is slightly darker, and the hairs on it are grayish to black, depending on the light. The mesonotum is grayish-black with a silvery-gray, lyre-shaped pattern that is lighter anteriorly and grayish laterally and posteriorly. The pattern may appear thicker in different lighting, and its anterior border can become black, shining brightly in silky light gray. Sparse, upright hairs cover the mesonotum. The scutellum is blackish-gray, and the hairs on the scutum and scutellum are light gray. The metanotum is velvet blackish, and the pleura is blackish gray. Wings exhibit yellowish veins with brown hairs and spines. The stem of the halteres is yellowish-brown, and the knob is yellowish-white. Legs are mostly blackish, but the basal portions of femur III, basal half of tibiae I-III, basal half of basitarsus II, 3/4 of basitarsus III, and the base of tarsites II-III are light brownish. The abdomen is light grayish powdery, with tergite I being dark grayish. Tergites II-V have black subtriangular median spots, while tergite VII has lighter and powdery spots. Tergites IV-V also have 1+1 lateral, blackish, subrectangular spots that do not reach the posterior border. The pleural tuft hairs are light gray, and the spermatheca has small internal spines. Male individuals have wings measuring 2.8-3.0 mm. The head coloration is similar to that of the female. The scutum is black-gray with 1+1 subtriangular spots anteriorly, covered by sparse, silky grayish hairs. The abdomen is blackish with larger gray spots on tergites II, smaller ones on tergites VII-VIII, and mostly grayish on VI and IX, except for a small and short median darker spot. The pleura, halteres, and wings resemble those of the female. Legs are yellowish-brown with light gray hairs, and blackish brown on coxae, apex of femur III, apex of tibiae, all of basitarsus I, distal third of basitarsi II and III, and tarsites. The hind basitarsus is three times as long as wide, and the calcipala is absent.
