Description: This species is distinct in color with sexually dimorphic coloration: males are a deep uniform orange while females are milk white without definite color markings. The vertex is bluntly angled, 1/3 to 1/2 wider between the eyes than in the middle. The female pregenital sternite is twice as broad as it is long, with the posterior margin excavated half way to the anterior base with a broad triangular notch, which is interrupted in the middle on either side with rounded lobes; this gives the appearance of three distinct notches. The male genital plates are longer than broad, with rounded tips that diverge slightly from one another. Adults are 5.0-5.5 mm long. (DeLong 1941), (DeLong 1948)
