Nine isolated teeth recovered from the Creechbarrow Limestone Formation are here described as a new late Middle Eocene ischyromyid genus and species Patriarchamys batesi gen. et sp. nov. Its relationships are discussed with reference to the continental European and North American paramyid faunas. Its closest affinity is with Pseudoparamys and possible ancestral relationship with modem sciurids is indicated.
