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], and 13 extinct species in the three genera Karasawaia, Montezumella and Stintonius [3]. Many of these crabs were formerly treated as members of the Atelecyclidae [4]. The family's fossil record extends back at least as far as the Eocene [5].
