Geographical Distribution:

Recorded Distribution(s):
It occurs in Mexico and Central America. In 1950, DeLong (181) reported it from the States of Jalisco, Michoacán, and Puebla. In addition to these States, in 1951 Cervantes and Rodriquez (126) reported it from Morelos, Veracruz, Querétaro, Guanajua¬to, Nayarit, and Guerrero. It is common above 750 meters in cen¬tral Mexico (Barnes 1954) [46]. (Nielson, 1968)

This species is a vector of corn stunt virus in Mexico. In 1950, Niederhauser and Cervantes (560) were first to report this species as a vector of this virus. The minimum incubation period in the vector was 20 days. The corn plants showed symptoms 4 to 7 weeks after inoculation. In 1951, Cervantes and Rodriquez (126) confirmed transmission after obtaining from 35.7- to 100-percent transmission efficiency to corn plants. The incubation period of the virus in the vector varied from 19 to 30 days. Maramorosch (485) produced a toxemia on corn with this species in 1959.
(Nielson 1968)

This species is considered the most important vector of corn stunt virus in the central highlands of Mexico.

Species Description

Length:
Small, linear species. male 3.60—3.90., female 3.80—4.00 mm.

Colour:
General colour yellowish brown or tan. Crown with two distinct small subquadrate spots; pronotum yellow with four longitudinal light brown bands; elytra tan, subhyaline.

Genitalia:
Pygofer in lateral aspect about 11/3 times as long as wide, candal margin deeply excavated, caudodorsal margin with distinct spine, caudoventral margin with short spine, ventral margin distinctly scierotized; aedeagus in lateral aspect with basal part broad and lobelike, distal part narrowly attenuated and tubelike; gonopore terminal; style in dorsal aspect simple, apices narrowed; female seventh sternum in ventral aspect elongate and pointed apically.

Species Diagnosis

This species is similar to Dalbulus maidis in general habitus and can easily be separated by the male pygofer with the ventral margin distinctly sclerotized, the distinctive aedeagus, and the female seventh sternum, which is elongate and acutely angled distally.
