The family Calcitronidae is an extinct group of arachnids. Its two monotypic genera are only known from Pliocene deposits of calcite in Arizona.[2] The family has been placed in the order Schizomida, but a review of the order concluded that "the fossil taxa ... are so poorly known that final placement must await further study and possibly new material",[3] and they are not listed in the order in a 2016 catalog of fossil arachnids.[4]
