Curculio Curculis lupus: biology, behavior and morphology of immatures of the cannibal weevil Anchylorhynchus eriospathae G. G. Bondar, 1943.

Weevils are one of the largest groups of living organisms, with more than 60,000 species feeding mostly on plants. With only one exception, their described larvae are typical plant-feeders, with mouthparts adapted to chewing plant material. Here we describe the second case of a weevil with early-instar larvae adapted to killing conspecifics.

A new species of Anchylorhynchus Schoenherr (Coleoptera: Curculionidae) from the Amazon, with a record of a new host palm for the genus.

Anchylorhynchus vanini sp. nov. from the Amazon is described, including the mouthparts and male genitalia.
