Distribution Map
(simplified continental distribution)
Geographical Distribution:
North America

Recorded Distribution(s):
The species is restricted to California. According to Oman (1938), the species is known only around the low hills near Los Angeles. However,DeLong and Severin (1949) showed that this species occurred in Santa Barbara and Orange Counties. (Nielson, 1968)

This species is a vector of Pierce’s disease virus of grape in California. Frazier and Freitag (275) were first to report this species as a vector of this virus in 1946. Transmission was accomplished from diseased alfalfa to one of three healthy alfalfa test plants.
(Nielson 1968)

Transmission by this species has not been confirmed, and it is regarded here as an unimportant vector in the natural spread of this virus.

Species Description

Length:
Large, slender species. male 8.00—8.50 mm., female 8.30—9.20 mm.

Colour:
General colour light yellow. Crown light yellow with seven distinct black spots; pronotum light yellow with three black transverse spots; elytra light yellow with orange longitudinal stripes.

Genitalia:
Pygofer in lateral aspect slightly wider than long, caudal margin obtusely angled; aedeagus in lateral aspect broad, tubelike with dorsal margin of shaft expanded laterally, paired subterminal processes on ventral margin, processes heavily spined at basal half, projecting laterad in ventral aspect; gonopore terminal; style in dorsal aspect with apical third narrow and curved laterally at apex, lateral spine near apex; female seventh sternum in ventral aspect with caudal margin slightly convex and slightly notched at middle.

Species Diagnosis

This species, related to triunata on the basis of the genitalia, can be separated by the aedeagus with a pair of short processes, which are covered with minute spines. DeLong and Severin (1949) figured the genitalia and Severin (1949) produced colored illustrations of the adults.
