ABSTRACT: The main purposes of this paper are to describe the larva of Anthonomus rubricosus Boheman (Curculionidae: Anthonomini) and to provide new information on its host plants. The species is similar to Anthonomus vestitus Boheman, based on the presence of four epipharyngeal sensilla arranged in a single cluster and the labial palpus one-segmented. It differs by its smaller body size (about 2 mm), basal segment of maxillary palpus shorter than apical segment, and premental sclerite with posterior extension shorter than anteromedian extension. Teneral adults, larvae and a pupal exuvia of A. rubricosus, the latter along with a parasitoid (Pteromalidae), were found inside flowers of Hibiscus rosasinensis L. and fruits of Pavonia sp. (Malvaceae), in Misiones Province, Argentina.
