Abstract

The Neotropical planthopper genus Trigava O’Brien, 1999 (Hemiptera, Fulgoromorpha, Dictyopharidae, Nersiini) is revised. Four species are included: T. brachycephala (Melichar, 1912) (the type species, from Peru), T. obrieni Song, Malenovský & Deckert, sp. nov. (from Brazil), T. peruensis Song, O’Brien & Bartlett, sp. nov. (from Peru), and T. recurva (Melichar, 1912) (from Bolivia and Peru). Lectotypes are designated for Igava brachycephala Melichar, 1912 and Igava recurva Melichar, 1912. All species are described, including habitus photographs and detailed illustrations of the male genitalia. Male and female genitalia are described for this genus for the first time. A key for identification of the species of Trigava and a distribution map are provided.
