Description of larva and pupa of the weevil hybolabus amazonicus voss (Attelabidae: Attelabinae), a leaf roller on Brazil nut (bertholletia excelsa)

Abstract

The last instar larva and the pupa of Hybolabus amazonicus Voss, 1925 are described and illustrated, based upon adults and immatures collected in the Amazonian Region (Acre and Amazonas, Brazil). The larvae live and develop inside a leaf-roll made by the female weevil. Although the species has already been reported damaging leaves of the Brazil nut (Bertholletia excelsa Humb. & Bonpl., Lecythidaceae) in the states of Acre and Amazonas, the preimaginal stages have not been formerly described. These are the first descriptions of larva and pupa of a species of the genus Hybolabus Jekel, 1860.
