Validation of Pedinocyclus and Quinquerhabdus, New Calcareous Nannoplankton Genera

Abstract

Validation of the names of these two calcareous nannoplankton genera is necessary because generic diagnosis was not given in Bukry and Bramlette (1969) and because a proposed new genus name, Leptodiscus, has been determined to be preoccupied by a dinoflagellate (Leptodiscus Hertwig, 1877). We thank Dr. Alfred R. Loeblich, Jr., for bringing this to our attention.
