Definition

Noun 1. A type of beetle characterized by antennae with flattened, plate-like segments at the tip: This term refers to any beetle belonging to the former superfamily Lamellicornia (now often considered part of Scarabaeoidea), which includes scarabs, dung beetles, and stag beetles. The defining feature is the antennae, which end in a distinctive club composed of several flat, plate-like segments (lamellae) that can be fanned out or folded together.
