Identification
Basically identical to G. assimilis, but found in a different region. Songs are different. From other species it differs in having pronotum at least somewhat pubescent, and having a distinctive pattern of brown and black (proportions of light to dark varies so some individuals appear darker than others - but pattern remains the same), including a dark streak along the sides of the pronotum and stripes on the head.

Very dark individuals can be nearly black, and very difficult to separate from other species occuring in the same region, but the pubescent thorax, usually a pale stripe along the angle of the folded tegmina, and at least traces of stripes on the top of the head should separate most of them.

G. personatus can look similar, but usually has pale areas more extensive (including legs and much of venter), lighter in color (tan), and the pattern usaully more contrasting. The song is similar in sound, but individual "chirps" are distinctly longer in G. multipulsator. The two species probably (?) do not occur together in the same places within the US (but they apparently overlap distribution in the desert southwest, where they probably occupy different habitats). G. personatus favors cracked ground in sparsely vegetated (often open desert or badland type) areas, while G. multipulsator apparently favors more heavily vegetated areas near water.
Range
s. California, s. Nevada, sw. Arizona, and the Pacific slope of Mexico
Life Cycle
Apparently does not diapause, and can be found at various stages of maturity (including adult) throughout the year.
