   Pseudophorid gastropods typically occur as warm-water (tropical-subtropical) elements in Late Ordovician-Permian strata. Silurian occurrences are known from the North Silurian Realm (North Atlantic Region) and Devonian occurrences are known only from the Old World Realm and Eastern Americas Realm. No occurrences are known from the cool- to cold water Malvinokaffric Realm during Silurian or Devonian time. New Silurian-Devonian taxa of this biogeographically distinctive gastropod family include three new genera: Late Silurian Gaspephorus, Early Silurian Peelophorus, and Bergmadsenella. In addition, a new species of Astralites, A. gamblei, from early Middle Devonian (Eifelian) strata of the Cheeneetnuk Limestone, McGrath A-5 quadrangle of west-central Alaska is established.
