The head is as wide as the pronotum, and the crown is slightly produced. The female pregenital sternite has a prominent posterior projection, with a slight median notch; the lateral lobes at the base of the projection are rounded. Adult males are 4.2-4.4 mm long, while females are 4.9-5.2 mm. (Hamilton 1975)
