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

Recorded Distribution(s):
This species is known only from California. In 1948, DeLong and Severin (196) recorded it from near Montara, San Mateo County. In 1957, Nielson (561) examined specimens from Lands End, San Francisco, and Stinson Beach. (Neilson, 1968)

This species is a vector of the western strain of North American aster yellows virus. Between 1947 and 1948 Severin (701, 703, 704) was first to report this species under the name of “Friscan’anus rupinatus” and “Friscananus ‘rupinatus var. brunneus” as a vector of this virus. Thirty-seven of 134 celery plants were infected with the virus. Natural infection was obtained by using 100 adults transferred from bracken to celery. Percent efficiency of transmission was 29. Transmission from diseased celery to healthy celery was effected after a 19-day acquisition feeding period. Transmission from diseased aster to healthy aster was not successful. Attempts to transmit curly top virus also failed.


(Nielson 1968)

This species is not considered an important vector in the natural spread of the virus in California.

Species Description

Length:
Medium size, slender species. male 4.20—4.60 mm., female 4.50—5.00 mm.
.

Colour:
General color yellow brown. Crown yellow brown, sometimes with two brown triangular spots at apex; pronotum yellow brown; elytra yellow brown, veins ivory or yellow.

Genitalia:
Pygofer in lateral aspect slightly longer than wide, ventral margin concave at middle, caudal margin broadly and obtusely convex, dorsal margin with distal part convex; pygofer spine straight, lanceolate, arising from middle of caudal margin, projecting dorsally; caudodorsal and dorsal submarginal areas with many long setae; aedeagus in lateral aspect with bifurcate processes about one-half as long as aedeagal shaft, flat and broad at midlength, narrowed apically, crossing in dorsal aspect; gonopore situated at about midlength of aedeagal shaft; style in dorsal aspect about 1½ times as long as connective; stylar shaft long, narrow, about three times as long as wide, curved slightly posterolaterally, sides nearly parallel, slightly wider basally, apex straight; stylar spine apical, long, pointed apically, projecting laterally; female seventh sternum in ventral aspect about twice as wide as long, lateral margins parallel, posterior margin truncate on each side of median spatulate process; median emargination U-shaped, very shallow, about one-fourth length of segment; spatulate process short, slightly longer than basal width, produced considerably beyond posterior margin, with sides nearly parallel, apex convex.

Species Diagnosis

From intricatus, to which it is similar in general habitus, rupinatus can be distinguished by the truncate caudal margin of the male pygofer. The male and female genitalia were illustrated by DeLong and Severin (1948) and Nielson (1957) . Severin (1948) presented color illustrations of the adults.
