Material examined.

3 spm (19 × 16 × 10 - 38 × 25 × 14 mm).

Synonymy.

Remarks.

Aldea and Rosenfeld (2011) commented that it is generally similar to Fissurella radiosa radiosa Lesson, 1831, sharing geographic distribution points. McLean (1984) mentioned the characteristics that differentiate them: Fissurella picta presents more wide shell margins in all of its development stages and the foramen is more centralized and presents black rays that do not occur on Fissurella radiosa .
