Neorhipidionina spiralis Hottinger, 2007
Description 1: oblique, almost centered section showing the semiinvolute early spiral stage. Note the umbilical depression. 2: oblique section inclined at about 20° with respect to the coiling axis. 3: section parallel to and near coiling axis. Note the disposition of the foramina on the septal face. 4: At bottom left an axial section of the holotype of this new species, and at the top right a transverse section parallel to the axis of coiling. 5: oblique, almost centered section. 6: section parallel to the axis of coiling. 7: oblique section inclined at about 45° to the axis of coiling. Note the umbilical depression on the left side of the section. 8-9: horizontal sections of the flaring adult parts of the shell showing the radial alignement of the septula in successive semiannular chambers. 10: oblique section of the flaring adult part of shell showing the radial pattern of the endoskeleton.
