Eurhinus festivus, photographed by Bernardo Navarrete.

Belongs within: Baridinae.

The Eurhinina are a group of weevils characterised by a brilliant metallic coloration in the adults. Larvae of the genus Eurhinus create galls in the stems of Vitaceae.

Characters (from Casey 1922): Body shining, wholly glabrous throughout; femora mutic; pygidium vertical and well developed, differing only slightly in the sexes. Posterior lobe of prosternum extending about as far as mesocoxal tangent. Antennal funicle often peculiarly modified, very thick and compact form in many species.
