Ericydeus
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.

Psylliodes punctulata is a species of flea beetle in the tribe Alticini, characterized by the enlarged hind femora that enable the jumping behavior typical of this group. The genus Psylliodes contains numerous species associated with brassicaceous host plants, though specific ecological details for P. punctulata remain poorly documented in available literature. Like other members of the genus, it likely exhibits the larval stem-mining habit and adult folivory that define Psylliodes ecology. The species name 'punctulata' refers to the punctate or dotted surface sculpturing typical of many chrysomelid beetles.
