The Notoxus is characterized by a distinctive elongated snout-like projection (rostrum) extending from the , a trait that separates these beetles from superficially similar ant-mimicking beetles in other families. Records indicate this species occurs in North America and Middle America. Like other anthicids, are likely associated with flowers and vegetation where they feed on pollen and small insects.
