Abstract
The Hystricuridae, previously regarded by most workers as a paraphyletic group, is considered on the basis of new and revised silicified species from Utah and Nevada. Major subgroups of hystricurids appear to be monophyletic, but the sister group relationships of several related families require investigation. The Hystricurinae is restricted to Hystricurus Raymond, 1913, Tersella Petrunina, 1973, and Flectihystricurus gen. nov. (type species: Hystricurus flectimembrus). A new subfamily Hintzecurinae is diagnosed. The subfamily appears to be restricted to the upper Skullrockian Stage, and comprises the new genera Hintzecurus (t.s.: Hystricurus paragenalatus), Genalaticurus (t.s.: Hystricurus genalatus), Ibexicurus (t.s.: I. parsonsi sp. nov.), Lavadamia (t.s.: L. joplinae sp. nov.), Politicurus (t.s.: Hystricurus politus), and Rossicurus (t.s.: Hystricurus lepidus).
