least 25 times as long as its narrowest width They range in length from about 7 to 10 mm. The wings are either clear or have very faint brownish markings, have an alula that is much narrower than cell c at its base, a reduced anal angle, and small bare spots near the base, with faint clouding along The apical crossveins.
The eyes have very short and sparse hairs, while its frons and face are mostly pollinose and black.
The antennae are yellow to black and very short, with the scape at least as deep as it is long.
The thorax has short hairs on its scutum, which is mostly shining lightly pollinose above and on the sides, which are either entirely black or with a few yellow margins. The scutellum is similarly colored, but with pile only as a fringe laterally.
On the pleural area the anterior anepisternum, meron, metapleuron, and metasternum are all bare. The upper and lower katepisternal hair patches are widely separated. The postmetacoxal bridge is complete. There is also no posteromedial apical hair tuft on the hind coxa.
In the male, the abdomens are about 40 times longer than the shortest width of segment 2, while female abdomens are 25 or more times longer than the shortest width of segment 2.
In addition to being dark brown to black in color throughout in most specimens, there are reddish hues towards the apex for some females, as well as yellow spots or bands appearing on tergites 2-5, which vary by species.
