A new species of planthopper in the genus Paraphenice (Hemiptera: Derbidae: Otiocerinae) from palms in eastern Madagascar.

A survey of planthoppers associated with palms in Madagascar was initiated to assess putative vectors of a phytoplasma causing palm decline. Here a derbid collected from a Chinese fan palm (Livistona chinensis) is described as Paraphenice fluctus sp. n., with supplemental molecular data for the cytochrome c oxidase subunit I (COI) gene, 18S rRNA gene, and D9D10 expansion region of the 28S rRNA gene.

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., 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.
