- Metrioxenini (metrioxenines) are a tribe of belids, primitive weevils of the family Belidae, containing about 30 species. They are only found in two widely separated areas, Southeast Asia extending to Indonesia, and South Africa. In the Paleogene, they were found at least in North America and Europe also, occurring perhaps across the entire Northern Hemisphere. As in other belids, their antennae are straight, not elbowed as in the true weevils (Curculionidae). They are far less characteristic than their presumed closest living relatives, the Aglycyderini. They can be recognized by the sharp-sided rostrum ("snout"). Also, their eyes are bordered by a wide and ridged groove. shows two sharp ribs on each elytron, which are absent in the other genera. These, by contrast, have their tarsal claws fused together at the base (they are unfused in Metrioxena) and grooves on the pygidium which are absent in Metrioxena. (en)
