Hydrothecae alternately arranged in one plane, large and tubular. Adcauline hydrothecal wall adnate for approximately one-third of its length. Free part of adcauline hydrothecal wall straight or slightly convex. Abcauline hydrothecal wall straight or slightly concave. Cusps of hydrothecal aperture sharp and separated by deep embayments. Occasionally with hydrothecal renovations. Gonothecae ovoid, with short distal neck; walls smooth or slightly wavy, with indistinct striae. |
