In 1913 Horace Gunthorp described a new Kansan lithobiid, Lithobius kansensis (4, p. 166), which he compared with what he took to be a closely related species, cantabrigensis Meinert (5, p. 177). Although the new species was inadequately characterized, it is still possible to say that it is undoubtedly referrable to Tidabius, a group proposed by R. V. Chamberlin in November of the same year (2, p. 80).
