Description: A pale tan species with four bold black dots on the edge of the vertex; the two inner dots are noticeably larger than the two dots at the apex, characteristic of this species. Adults are small, around 3.0 mm long or smaller. The combination of the coloration and pattern, together with the small size, are key characteristics for distinguishing this species from others in the genus; the wing venation is also more complicated than in other members of the genus, with more small cells. The individual male genital plates are triangular in shape, with sharp apexes that are divergent from one another. The female pregenital sternite has a moderate, rounded excavation on the medial half of the posterior margin, with a slight convex tooth in the middle and convex lateral margins to the sternite; the excavation is bordered with brown.

Habitats and Life History
Habitats: Has been found in a grassy, open area near forest edge.
Plant Associates:
Behavior: Can be attracted at night with a light.
Comment: This species is a known vector of sorghum stunt mosaic rhabdovirus (SSMV) and can therefore cause economic agricultural damage. (APS)

This species could be mistaken for the much larger G. fitchii: both have similar coloration and pale faces. However, fitchii has very bold pale wing venation that contrasts with the rest of the wings, and the pronotal lines are boldly defined; in sonora, the wing venation does not stronly contrast with the rest of the wings. Additionally, the black markings on the vertex of sonora are two different sizes, with the two central spots noticeably smaller than the outer ones. In fitchii, these spots are relatively the same size.
