description |
A pale species with a head, pronotum, and scutellum that range from light yellow to yellow. The wings are also largely some form of yellow, but there is [typically] a characteristic yellowish-orange to deep orange to reddish stripe/band along the commissural margin of the wings, extending from the sides of the scutellum towards the apical crossveins. In some pale individuals, the wings are whitish-hyaline with yellow veins. There is a transverse band of three defined black spots in a row along the apices of the inner three basal cells, anterior to the apical crossveins. The abdomen is black dorsally, with the outer margin of each segment yellow. Male subgenital plates are yellow. Adults are around 3.5 mm long. (Christian, 1953) |

This species can be similar to form I of O.
flavomarginata, as both species have a flavescent stripe along the commissural margin of the wings. While the stripe is typically more red in flavomarginata, the key difference is the row of black spots near the apical crossveins; in australis, this band of spots extends straight across, while in flavomarginata the band obliquely slants towards the costal margin.
