Ceratocanthidae
Ceratocanthidae are a family of Scarabaeoid beetles that are best known for their ability to roll up when disturbed into a nearly spherical shape giving the name of pill scarab beetles.
Ceratocanthidae have a 10 segmented antenna with the terminal three segments forming an opposable club. The basal antenna segment is large and triangular. The eyes are partly separated by a canthus. There are five tarsal segments on all the legs. They were earlier placed in the family Acanthoceridae. The family is closely related to the Hybosoridae.
