Six species of broad nosed weevils of the subfamily Entiminae are recorded as harmful for berries in Argentina. Three of them are exotic and distributed along the Patagonian forests: Otiorhynchus ovatus (Linnaeus), O. rugosostriatus (Goeze) and O. sulcatus (Fabricius) (Otiorhynchini) and three are native and range in the northern and central areas of this country: Hyphantus sulcifrons Boheman (Anypotactini), Naupactus xanthographus (Germar) and N. cervinus Boheman (Naupactini). Larvae live in soil and bore externally on the roots of their host plants, causing more damage than adults that usually feed on the leaves. The main objectives of this contribution are: to give a dichotomous key, diagnoses and habitus photographs for the identification of the six species; to provide information on their geographic distributions, host plants and biology; and to bring the first record of O. ovatus for Argentina and new host associations with cranberry and strawberry.
