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

Abstract

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., C. culenesensis Sanborn & Cole n. sp., C. curacaviensis Sanborn & Cole n. sp., C. impartemporaria Sanborn & Cole n. sp., C. magna Sanborn & Cole n. sp., C. mapuchensis Sanborn n. sp., C. oraria Sanborn & Cole n. sp., C. parrajaraorum Sanborn n. sp., C. partemporaria Sanborn & Cole n. sp., C. pehuenchesensis Sanborn & Cole n. sp., C. trifascia Sanborn n. sp., C. trifasciunca Sanborn & Cole n. sp., and C. viridicitata Sanborn & Cole n. sp. are described as new. Chilecicada occidentis Walker, 1850 is re-described to facilitate separation of the new species from the only previously known species. Song and cytochrome oxidase I analysis available for most species support the separation of the new taxa from the type species of the genus. Known species distributions and a key to the species of the genus are also provided. The new species increases the known cicada diversity 61.9% to 34 species, 91.2% of which are endemic to Chile.
