The Pylojacquesidae are a small family of hermit crabs comprising only two species in two genera. The family was erected in 2001 after two specimens at Museum für Naturkunde at the Humboldt-Universität zu Berlin were recognised as being quite distinct from other described hermit crabs. The family members differ from other hermit crabs in that their mandibles are chitinous and toothed.
