The cicada genus Chilecicada Sanborn n. gen. is described to accommodate the Chilean species, C. occidentis (Walker, 1850) n. comb., which is redescribed and illustrated, with the first description of the female. The new genus is placed in the Chilecicadini Sanborn n. tribe. Ahomana Distant, 1905 is transferred from the Tibicinini within the Tibicininae to the Carinetini within the Cicadettinae. A lectotype is designated for Ahomana neotropicalis Distant, 1905.
