Description
editMetoponium is one of several darkling beetle genera to have the ends of the protibia expanded dorsally.[1][3] It can be distinguished from related genera by the epistomal lobe (front edge of the head) being slightly concave and the presence of distinct carinae over the eyes.[1][3]
Ecology
editBeetles of this genus have been found to damage crops such as tomato[4] and watermelon.[5]
