This species is a vector of Pierce’s disease virus of grape in California. Freitag et al. in 1935 (287) were first to report this species under the name of “Homalodisca liturata” as a vector of this virus. The leafhopper fed on diseased plants from 1 to 2 days and on test plants from 2 to 10 days. It proved to be a very efficient vector by transmitting the virus from diseased grape and alfalfa to 61 percent of healthy grape and alfalfa test plants. Samples of the population taken from natural habitats failed to show natural infectivity (Freitag and Frazier 1954 [286]).
(Nielson 1968)

This species is not considered an important vector in the natural spread of the virus in view of its incidental association with grape vineyards and alfalfa fields.

Species Description

Length:
Large, slender species. Length of male 9,00—9.10 mm., female 11.0—11.20 mm.

Colour:
General color light brown to black. Crown and pranotum brown to black with yellow or ivory irregular markings, coarsely rugulose; elytra subhyaline.

Genitalia:
Pygofer in lateral aspect about 11/3 times longer than wide, caudoventral margin produced posteriorly to broad convex lobe; aedeagus in lateral aspect with two pairs of apical processes, lateral pair very broad, short, truncate, caudal pair extremely long, narrow, attenuated apically and projecting dorsally; gonopore dorsal; style in dorsal aspect simple, inner margin serrate, small hooked spine subapically; female seventh sternum in ventral aspect with caudal margin distinctly concave.

Species Diagnosis

This species is similar to coagulata in genital characteristics and can be separated by the aedeagus with the short, truncate, lateral atrial processes.
