Identification
Toxonotus can be distinguished from true weevils ( Curculionidae) by their straight, non-geniculate rostrum. Within Anthribidae, identification to species level requires examination of subtle morphological characters including antennal club structure, pronotal and elytral sculpturing, and body proportions. The name refers to the bowed or arched notum, a characteristic profile useful for recognition.
