Phylogeny of North Americas largest cicada radiation redefines Tibicinoides and Okanagana (Hemiptera: Auchenorrhyncha: Cicadidae: Tibicininae).

Tibicinoides, with three small endemic California cicada species, has a confusing, intertwined systematic history with Okanagana that we unravel here. An ingroup including all species of Tibicinoides and the majority (84.7%) of Okanagana species were sampled for six gene regions, polarized with Clidophleps, Okanagodes, Subpsaltria, and Tibicina outgroups, and subjected to Bayesian phylogenetic analysis.

Thirteen new species of Chilecicada Sanborn, 2014 (Hemiptera: Auchenorrhyncha: Cicadidae: Tibicininae) expand the highly endemic cicada fauna of Chile.

The genus Chilecicada Sanborn, 2014 is shown to be a complex of closely related species rather than a monospecific genus. Chilecicada citatatemporaria Sanborn Cole n. sp.
