Leptopleuroninae is an extinct subfamily of procolophonid reptiles.[2] It is defined as all taxa closer to Leptopleuron lacertinum than to Procolophon trigoniceps.[2] The oldest member of Leptopleuroninae is Phonodus dutoitorum from the Induan age of the Early Triassic.[3] It is the only procolophonid group that survived into the Late Triassic.[4]
