Face with subantennal sulci widely separated from each other at junction with clypeus; back of head divided by transverse or oblique sutures into dorsal occiput and ventral genae; pronotum divided into 2 lobes abutting medially; female funicle 8-segmented; dorsellum rhomboidal; propodeum usually with several incomplete, finer and less distinct longitudinal carinae between the submedian carinae; forewing setae usually absent behind venation and usually relatively sparse beyond venation; female gaster often projecting ventrally under mesosoma. The species of G. ( Gastrogonatocerus ) are usually smaller than species of the other subgenera, drymounted specimens rarely being longer than 1000 µm. Distribution. Neotropical region, Nearctic region ( USA , Mexico ), and the Hawaiian Islands ( Hawaii , USA ). Hosts. Membracidae .
