Although so generally confused with the Hoplides these 

 insects are quite distinct. They are closely related to the 

 South American genus Ceraspis, which also exhibits most of 

 their characteristic features. They are distinguished from 

 the Hoplides by the possession of six exposed ventral seg- 

 ments, symmetrical claws, and the normal complement of 

 tibial spurs — that is, one upon each front tibia and two upon 

 each of the others.
