Plocamus

Plocamus species can be distinguished from other flower weevils by their compact body form and the presence of distinctive setal patterns on the elytra. P. echidna and P. hystrix bear notably spiny or hispid (bristly) integuments, reflected in their species epithets. The genus is characterized by a short, broad rostrum relative to many other Curculionidae. Species-level identification requires examination of genitalia and detailed setal arrangement patterns.

Found in association with flowering vegetation; specific microhabitat preferences vary by species. P. echidna has been collected from various herbaceous plants and low vegetation.

North America, with records from the United States and likely extending into adjacent regions of Mexico and Canada. Most described species were based on specimens from the southern and western United States.

• AnthonomusBoth genera contain flower-associated weevils with compact bodies; Plocamus differs in rostral proportions and lacks the pronounced elongation seen in many Anthonomus species.
• GymnetronShares flower weevil habits, but Plocamus species generally exhibit more robust body forms and distinct setal patterning on the elytra.
