Cheiragonidae is a small family of crabs, sometimes called helmet crabs , ^[1] placed in its own superfamily, Cheriagonoidea. ^{[2] [3]} It comprises three extant species, Erimacrus isenbeckii , Telmessus acutidens and Telmessus cheiragonus ; ^[2] there are no yet evidences of Cheiragonidae in the fossil record. ^{[3] [4]} Many of these crabs were formerly treated as members of the Atelecyclidae. ^{[5] [6]}
