Hybosoridae

Definition

A family of scarabaeiform beetles (order Coleoptera), commonly called scavenger scarab beetles, comprising more than 600 species in approximately 78 extant genera. Members are predominantly tropical in distribution and are thought to feed on decaying organic matter, though their biology remains poorly documented compared to related scarab families.

Etymology

Example

The genus Ceratocanthus, placed in Hybosoridae, exhibits the compact, rounded body form typical of scavenger scarab beetles that burrow in decomposing plant material.

Synonyms

• scavenger scarab beetles

Usage Notes

Distinguished from the larger and more diverse family Scarabaeidae (true scarabs, dung beetles, chafers) by subtle adult and larval characters; the family's phylogenetic position within Scarabaeiformia has been revised in recent molecular studies. Most species are rarely collected due to their cryptic habits in decaying wood, leaf litter, and compost.
