Megalopodidae

Definition

A small family of leaf beetles (Coleoptera) containing approximately 30 genera, primarily distributed in circumtropical regions. Formerly classified as a subfamily of Chrysomelidae, Megalopodidae was elevated to family rank based on phylogenetic studies. The family comprises two subfamilies: the nominate Megalopodinae and Zeugophorinae (the latter also historically placed within Chrysomelidae). Adults and larvae feed on plant material, with some species associated with woody hosts.

Etymology

From Greek megalo- (great, large) + podos (foot), referring to the enlarged hind femora characteristic of some members.

Example

The genus Zeugophora, placed in subfamily Zeugophorinae of Megalopodidae, contains species whose larvae are leaf-miners on trees and shrubs.

Usage Notes

Taxonomic placement has been unstable; older literature treats this group as Megalopodinae within Chrysomelidae. Current classifications (supported by molecular phylogenetics) recognize it as a distinct family within Chrysomeloidea. The family is relatively species-poor compared to the megadiverse Chrysomelidae.
