  1. Striae interrupted by longitudinal lines
  2. Striae more widely spaced about central area
  3. Valves 7-9 µm wide

Kobayasiella okadae has valves 7-9 µm wide and a pair of distinct longitudinal hyaline lines that interrupt the striae between the raphe and valve margins. Together these lines form a lanceolate shape within the valve. Striae are very fine near the valve apices but much more widely spaced about the central area, where they may be distinguished in LM.
