概要

• 論文の詳細を見る

• Nine species of five lophophaenid genera are described from the Lower Miocene Toyohama Formation, Morozaki Group, Aichi Prefecture and the lowest Middle Miocene Oidawara Formation, Mizunami Group, Gifu Prefecture, central Japan. A special attention is given to describing and illustrating the details of their skeletal structures which possess one or two horizontal rings, since it is believed that these details are important in establishing the taxonomy and clarifying the phylogenetic relationships. The examination discriminates seven types of skeletal structure. Four species are newly described, and two new genera, Steganocubus and Cryptogyrus, are also erected herein.
