Brentidae as used here includes the Apionidae. Brentids have most of the features of typical weevils, but almost all can be distinguished by the straight antenna. Brentinae are usually elongate and slender, while and Apioninae tend to be shaped like a "tear-drop", wide posteriorly and narrowed anteriorly. |
