Siphluriscidae is a family of mayflies. It contains a single extant species, Siphluriscus chinensis, which is native to Vietnam and China. It is thought to be the most primitive living lineage of mayflies. A fossil genus, Stackelbergisca is known from several species from the Jurassic and Early Cretaceous of Asia. A second species of Siphluriscus, S. davidi was later assigned to the genus Siphlonurus.
