The genus Xanclomys, named by Rigby J.K. in 1980, is also known as Xancolomys. The identification is based on a single species, Xanclomys mcgrewi. Fossil remains were found in the Torrejonian (Paleocene)-age strata of the Swain Quarry in Wyoming (U.S.). Affinities are uncertain. There's perhaps a second, unnamed species.
