Adults of this species resemble mosquitoes in appearance. The head is rounded, with shortened non-biting mouthparts. The antenna features well-developed flagellomeres and shows sexual dimorphism, with males having plumose antennae. The eyes are round and dichoptic, with microtrichia present between the ommatidia. The clypeus is well-developed and larger than the labrum. Mouthparts are reduced, and the mandibles, hypopharynx, labium, and labella together form a food canal. The head bears numerous setae. The thorax possesses two well-developed functional wings and is dorsally convex, providing space for the attachment of flight muscles. It is demarcated into the anterior pronotum (prothorax), medial mesonotum (mesothorax), and posterior postnotum (metathorax), with the mesonotum being the largest part. The wings are setose and exhibit venation, including six primary veins: the humeral crossvein, costal vein, radial vein, medial vein, cubital vein, and anal vein. There is sexual dimorphism in wing shape, with female wings being relatively broader than male wings. Three pairs of legs (forelegs, midlegs, and hindlegs) are present, each consisting of one femur, one tibia, and five tarsomeres. The abdomen is dorsoventrally flattened and also displays sexual dimorphism, with the female abdomen being shorter and broader than that of the male. The terminal abdominal segments bear genitalia. In males, the genitalia comprise paired claspers consisting of a basal gonocoxite and apical gonostylus, surrounding the Y-shaped anal point. The gonocoxite bears several appendages called volsellae. Male genitalia transfer a spermatophore (sperm package) to the female spermathecae. Female genitalia mainly consist of gonapophysis and gonocoxite.
