This species is a vector of phony peach disease virus in the Southeastern United States. In 1949, Turner (792) was first to report versuta as a vector of this virus, and ten years later in 1959 Turner and Pollard (795) confirmed the transmission. Percent efficiency of this vector was 22.2 in all tests conducted between 1947 and 1955. The minimum acquisition feeding period was 1 day and the latent period less than 17 days.
(Nielson 1968)

The species is not considered a primary vector of this virus since it only fed occasionally on peach and had no direct ecological association with this host.

Species Description

Length:
Medium size, slender species. male 5.00—5.50 mm., female 5.50—5.70 mm.

Colour:
General colour yellowish red to reddish brown. Crown yellowish red with linear fuscous markings; pronotum light yellowish red along anterior margin, reddish brown posteriorly; elytra reddish brown with long bluish band along claval suture.
.

Genitalia:
Pygofer in lateral aspect slightly longer than wide, caudal margin convex about middle; aedeagus in lateral aspect short, shaft grooved along middle in ventral aspect with two apical processes extending laterally on each side of shaft; paraphyses asymmetrical with pair of terminal, long, bladelike processes; style in dorsal aspect simple, apex truncate; female seventh sternum in ventral aspect with caudal margin triangularly convex.

Species Diagnosis

This species, related to cythura, can be separated by the aedeagus with the shaft narrowed apically in lateral aspect.
