Oedionychina (Coleoptera: Chrysomelidae: Galerucinae: Alticini) from the Parque Estadual Altamiro de Moura Pacheco, a Cerrado remnant

Abstract

Oedionychina Chapuis, 1875 is a large group of flea beetles that have been the subject of several taxonomic studies in recent years. Here, we present data on external morphology and genitalia of six species of Oedionychina from the Brazilian Cerrado. High-quality photos are included. We update descriptions of three known species, Alagoasa burmeisteri (Harold, 1881), Omophoita magniguttis Bechyně, 1955, and Paranaita opima (Germar, 1824), and describe three new species, O. mateusi sp. nov., Walterianella marae sp. nov., and Walterianella tapuiae sp. nov. The specimens were sampled at the Parque Estadual Altamiro de Moura Pacheco (PEAMP), Goiás, Brazil, a remnant of Cerrado mostly covered by semi-deciduous forest. These updates are part of our ongoing efforts to elucidate the diversity of Oedionychina in the Cerrado.
