The family Thryonomyidae is represented in the Lower Miocene of Saudi Arabia by a single species, Paraphiomys knolli sp. nov. This new taxon differs from all other thryonomyids in being small, lower molars having a short metalophulid II and an isolated anterolabial cuspid, and upper molars being antero‐posteriorly compressed and pentalophodont. A cladistic analysis involving all extinct and extant species of thryonomyids is provided. Paraphiomys knolli branches as the sister‐species of Paraphiomys pigotti , type species of the genus.
