Description of the immature stages of the flea beetle Omophoita personata (Coleoptera: Chrysomelidae: Galerucinae: Alticini)

Abstract

Alticini is the most diverse tribe of Chrysomelidae with approximately 8,000 species. Despite of its high diversity, little is known about their natural history and immature stages. Herein, we describe the immatures of Omophoita personata (Illiger, 1807) reared in laboratory from adults sampled in field. We also investigated and compared with immatures of O. octoguttata (Fabricius, 1775). Detailed morphology and chaetotaxy are presented. Larvae of O. personata have their bodies covered with tubercles and the stemmata are absent. These characteristics are shared with other Oedionychina species, reinforcing the stability of these morphological characteristics as diagnostic of this subtribe. This study provides important descriptive and comparative data that increases the knowledge about Alticini immatures.
