Metoponium is a North American genus of darkling beetles.[1][2][3]

Description

Metoponium 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

Beetles of this genus have been found to damage crops such as tomato[4] and watermelon.[5]
