From Wikipedia, the free encyclopedia
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]
