Scaralina cristata is a species of planthopper in the family Fulgoridae.

It is found from Arizona in the United States south to the Sierra Madre Occidental in Mexico.

[1] Scaralina cristata typically occurs at higher elevations, above 1000 meters, and is associated with oaks (Quercus spp.).

[1] It has been reared on Quercus arizonica, but this may not be its preferred host species.

[1] Scaralina cristata is most often found in the Madrean Sky Islands in Arizona down into Sonora, but also with populations of putative conspecifics extending east of the Continental Divide into New Mexico, and south as far as the state of Durango.
