The Early Cretaceous (Valanginian) ammonite Homolsomites Crickmay, based on imperfect specimens of H. poecilochotomus Crickmay (= Holcodiscus? stantoni McLellan) from southwestern British Columbia, is redefined and the name applied to species from California, Oregon, Washington, and Greenland that have been described under other generic names. The genus is closely related to Tollia Pavlow from the late Berriasian of the Boreal region and is referred to the family Craspeditidae. Homolsomites is commonly associated with the pelecypod Aucella crassicollis Keyserling and with the ammonites Polyptychites, Neocraspedites, Lyticoceras, and Sarasinella.
