New planthoppers in the genus Colpoptera (Hemiptera: Auchenorrhyncha: Fulgoroidea: Nogodinidae) from lowland tropical rainforest and cloud forest in Costa Rica

New species of Colpoptera, C. acinaces sp. nov., C. alacutus sp. nov. and C. falx sp. nov. (Colpopterinae: Colpopterini), are described from Heredia and Alajuela Provinces, Costa Rica, where they were collected during a survey of planthoppers associated with palms. Molecular data for the five-prime region of the cytochrome c oxidase subunit I (COI) gene, 18S rRNA gene, and 28S rRNA gene are provided for available members of Colpopterini to support placement in Colpoptera.
