Metapion is a genus of beetles belonging to the family Brentidae.
The species of this genus are distributed only in the Palearctic zone and likely originate from deserts of Central Asia. They are commonly found in Southern Europe, northern parts of the Middle East, Caucasus and in Central Asia. Some species also appear in northern zones of Africa (south to Sudan).
Species of this genus appear to be associated with plants in the family Rutaceae, particularly the genera Ruta and Haplophyllum. The larvae are believed to develop by mining the roots, necks, and stems of these plants.
Description
Body black, covered with oval, lance-shaped or fine, hair-like scales. The proboscis has a broadening that is either sharply pointed or bluntly angled.
