The frontal tubercles are robust and cylindrical in shape. The antenna exhibits partial fusion of flagellomeres 10–11 and complete fusion of flagellomeres 12–13. Wing vein FCu is situated considerably distal to RM, with a ratio of VR Cu to 1.52. The anal point is wide at the base, narrowing distinctly towards the subapical region, and tapering to a pointed apex. The superior volsella possesses two setae at its apex. The digitus is elongated, extending beyond the superior volsella, curved, and terminating in a blunt apex. The stem of the median volsella is bulbous, featuring slender foliate lamellae.
