  broad-nosed weevils

  Ericydeus is a genus of broad-nosed weevils (Curculionidae: Entiminae: Naupactini) containing 16 described species distributed from the United States through Central America to Argentina. The genus was revised in 1995, revealing distinct biogeographic patterns: South American species form one clade and Central/North American species form another, with character evolution following a southern-to-northern direction. Species exhibit varied coloration including metallic green, coppery, and punctate patterns.
