Eight New Genera of Unilocular Foraminifera
Abstract and Figures
Although varied and diverse, unilocular foraminifera are among the least understood group of the foraminifera. Part of the problem has been the inadequate number of taxonomic divisions within this diverse group. A new taxonomic framework has been proposed to make the group more useful to taxonomists and stratigraphers. Several additional new genera are proposed herein. The new genera Hyalinonetrion (type species H. sahulense n. sp.) and Pygmaeoseistron (type species P. hispidulum) are included in the Lageninae. Five new genera also are included in the Ellipsolageninae. These include Cursina n. gen. (type species C. adornata n. sp.), Exsculptina n. gen. (type species L. sidebottomi), Favulina n. gen. (type species Entosolenia hexagona), Homalohedra n. gen. (type species Lagena guntheri), and Laculatina n. gen. (type species Lagena quadrilatera striatula). Bifarilaminella n. gen. (type species Lagena advena Cushman) is included in the Sipholageninae. Three additional new species are described: Favulina epibathra n. sp., Pytine petaloskelis n. sp., and Sipholagena structiloides n. sp.
