Lepidotrichidae is a family of basal insects belonging to the order Thysanura. The family is considered to contain two genera: the extinct Lepidotrix, known from specimens preserved in Baltic amber, and the extant Tricholepidion, which contains a single species, Tricholepidion gertschi. This species is an example of a living fossil, the one remaining member of a clade which was once widespread. Recent research has suggested the extant species should be assigned to its own family, Tricholepidiidae.
