From original description (Hull 1937).
Head: Eyes bare, broadly dichoptic in male. Antennae slender, the first joint sub-equal to last two. Arista thick, its surface pubescent. Hair of upper front directed upward, of vertex directed forward and upward so that the two converge above ocelli. Lower face just above mid oral margin equipped with a beard of long thick shining black bristles.
Thorax normal, thick black bristly, greatly appressed. Scutellum with a pair of enormous spines, deeply sulcate between, directed upward and posteriorward at an angle of 45 degrees. Legs: Hind basitarsi longer than remaining joints, greatly widened and flattened. Remaining joints similarly widened and flattened, but less so. Last section of fourth longitudinal vein (subapical cross vein) bluntly angulate outward, just before terminus the posterior angles of the first posterior and discal cells not angulate but evenly rounded. No spurs except for the posterior cell spur cutting down to terminys of spurious vein. Wings black basally, blackish on a narrow distal apex, and yellow with yellow veins between.
Abdomen broad and thick, the lateral posterior margins of the third segment and adjoining base of the fourth deeply sunken, followed by a simple situation on the next segment so that a strong ridge lies between.
