Mastogloia floridensis guide
  1. Valves rhombic
  2. Striae in two zones
  3. Striae alveolate
  4. Proximal raphe ends curved
  5. Partecta transapically elongated, isomorphic

Valves are large and distinctively narrow and rhombic. The apices are apiculate. The striae are separated into two zones on the valve face, with an inner zone of convergent striae and an outer zone of radiate striae. Partecta are transapically elongated and isomorphic, except the terminal partecta.
