Descrição de imaturos de Omophoita personata (Illiger, 1807) (Coleoptera: Chrysomelidae: Alticini)

Abstract

Holometabolic insects are characterized by having complete metamorphosis with the larval phase being characteristic of these insects. Coleoptera is the most diverse Order, with 40% of all insect species described, with Chrysomelidae Latreille, 1802 being the second most diverse family among Phytophaga. Within Chrysomelidae, the Alticini tribe is the richest in number of species, reaching 10,000 species, of which 1,407 occur in Brazil. Despite all the diversity in Alticini, studies dealing with biology, especially the description of immatures, are scarce with few records in the literature. The study of Alticini’s immature is important, as many species are agricultural pests and others are used in biological control. Characterizing the immatures also contribute to phylogenetic constructions that seek to establish relationships between groups in the evolutionary context. The present work describes the immatures of Omophoita personata (Illiger, 1807) for the first time. The immatures were examined, illustrated, and compared with the immatures of other species of Oedionychina subtribe and other Alticini. This study provides important data that broadens the knowledge of Alticini’s immatures.
